Which Is Better Air Cooled Chillers Or Water Cooled Chillers

[ad_1]

Chillers are the only way of beating the heat, when summers are near. The increased level of humidity in the air often makes people sweat profusely and serves as a breeding ground for bacteria and parasites. The humid air circulating indoors may aggravate sickness and allergic conditions, leaving the atmosphere unhygienic. Dehumidifier’s purify air indoors, rendering it fresh and safe to breathe in. Created for industrial purposes, these dry air Dehumidifiers are now progressively used in every new business set-up and household.

Chillers are basically a closed system, which utilizes the process of evaporation and condensation to cool the air in a room. Making use of drying technology, the dry air system cools the temperature by passing on the heat from the source to the evaporator coil. Basically, there are two kinds of chillers. One is air cooled and the other being water cooled. Air cooled chillers, as the name suggests uses air to dehumidify a space, whereas water cooled chillers uses water to cool a place.

There exists no formulae to find the perfect dehumidifier and neither of them would be suitable to every device. Each chiller has its own set of advantages and disadvantages and a buyer should effectively scrutinise them before investing in one. Space is one of the most important factors, when it comes to choosing a Dehumidifier. Air chillers are larger in size and require a large space for installation, whereas water cooled chillers are small, but require cooling towers and a mechanical room for effective functioning. Air cooled chillers would be unfavourable for industries, which have walls higher than the unit. They require continuous flow of fresh air and an obstructed air flow may create problems with recirculation. Water chilled coolers are more suitable, when there’s a lack of space and restricted air flow.

Every chiller produces a noise when it is in use. The noise of air cooled chillers cannot be determined as each fans installed in them would have a different decibel. Although, there are various ways to decrease the noise produced by them, it is always better to invest in a system, which is quieter. Air chillers are normally cheaper compared to the money spent on the maintenance of water chillers. The air coolers require less maintenance and don’t need cooling towers, condenser pumps or a mechanical room to function. However, the life span of air chillers is short and is less efficient compared to water chillers. Water chillers on the other hand, have a greater life span and work efficiently with continuous maintenance. Lifespan and the performance of the chillers depend on the quality of the chiller you choose. Ideally, it is always better to consult your local contractor before purchasing one.

Spray Foam Insulation and Its Benefits

[ad_1]

Regardless of whether looking to insulate a brand new building or retrofitting an old one, homeowners are finding spray polyurethane foam or SPF as an increasingly viable option. Essentially a spray applied plastic; it can form a continuous insulation as well as a complete air sealing barrier on walls, corners, and all contoured surfaces. In this process, unique liquid contents are mixed and reacted chemically together and quickly to expand on contact and form the foam to provide the necessary sealing and moisture barrier. This form of insulation is highly preferred not only because of its extremely commendable resistance to heat transfer but also because of its exceptional ability to reduce unwanted air infiltration through any joints, cracks or seams.

Types of SPF

Spray foam insulation is primarily of three types and used for specific purposes. They are –

  • High-density SPF which is predominantly used for exterior and roofing applications.
  • Medium density SPF which is mostly used for interior cavity fill, continuous insulation, and unvented attic applications.
  • Low-density SPF is best used for unvented attic applications and interior cavity fills.

Each type has its own unique advantages and normally an SPF contractor takes into account, the building, climate, project, budget, etc. and suggests the best option to go for. Apart from the structure of the foam, its method of delivery and installation also plays a critical role. It is also of three types i.e. high-pressure as well as low-pressure, two-component foam and insulating foam sealant.

Advantages of SPF

While each type of SPF has its own unique advantages and disadvantages, there are some common benefits and advantages of choosing this method, especially over fiberglass as an insulation means. Few of its key advantages are highlighted below:-

  • Powerful insulator

Due to its expansive nature, SPF insulation is much more effective than other types of insulation and effectively seals all nooks and crannies. With it, you are assured of not being left exposed. The method’s resistance value which is its ability to provide an air-tight seal is the best in the market at R-6.

  • Lower energy costs

Owing to its high efficiency as an insulator, it allows the property and house-owner to save significantly on their energy bills. In contrast to other methods saving about 30% in energy bills on average, The SPF insulation is known to reduce energy bills by 50% or more.

  • Air-tight seal

One big reason of mountainous energy bills is air leaks. However, no method takes better care of it than SPF. They can easily seal any holes or cracks in the smallest and the darkest of the place. Its airtight seal is so powerful that studies suggest it to be about 24 times less permeable than any other type of insulation to air filtration.

  • Moisture barrier

Any holes or cracks on the walls or other places not only allow air but also moisture and water to permeate inside the house. With its known potential to cause damage, it is imperative to keep them at bay. Being impermeable to water, the SPF not only fantastically protects the attic and crawl space from possible moisture and leaks but in the scenario for flooding for any reason, The SPF does not absorb moisture and water like other materials. This imperviousness to water helps and protects any living space.

  • Deters mold

SPF is composed of inert polymers which block of all possible source of food for the mold or bacteria. Thus no mold and mildew are able to thrive and the house gets insulated against it. The closed-cell SP is better in this trait than the open cell SPF.

  • Long life span

The inert polymer of the SPF facilitates them having an indefinite lifespan. Thus house owners and businesses are not required to re-insulate for years. Once installed, it can last up to 20 years or more with optimal performance.

How To Choose The Best Table Saw for Your Needs

[ad_1]

Shopping for a table saw is one of the most significant investment decisions a carpenter or wood-worker can make.

To make the right decision you really have to be specific about what your options are.

Types of Table Saws:

Virtually all table saws are categorized in one of these following classifications:

  • ‘job-site’ or portable table saws
  • contractor table saws
  • cabinet table saws
  • ‘hybrid’ table saws

For anyone hoping to buy a table saw, you need to understand what these categories mean, and what you can expect to get from saws in each category.

Portable Table Saws:

Portable table saws were developed for you to easily transport them round.

This is often beneficial to craftsmen along with others who spend considerable time on-site. Portable table saws nevertheless manage to carry out the same primary functions as heavier table saws, but on a lower level. Rather than having a large induction motor like on saws in other groups, these saws are typically powered with a compact universal motor. This may mean these saws have less power and may be noisier.

The progress made in the last few years to portable/job-site saws have ensured that they are far better and more desirable to serious wood workers.

Having said that, portable table saws lack sufficient enough power to cut through thick hard woods and tend to be inappropriately designed to give the true precision in which exceptional carpentry asks.

Contractor, hybrid, and cabinet saws provide better choices for the experienced wood-worker and extreme hobbyist, so now we’ll go through them in-depth.

Contractor Table Saws:

Contractor saws were originally meant to be light enough to be taken from site to site, on the go. Most have an open base and weigh in at about 250-350 lbs. They may also be priced within range of your keen hobbyist’s pocket.

Contractor table saws can be suited to simple cabinetry and carpentry tasks and straightforward furniture making. Tons of contractor table saws now feature premium fence systems. Making use of the highest quality saw blade, and utilizing blades suitable for a certain type of cut will certainly help the ability of a contractor table saw and allow it to complete some sophisticated carpentry projects.

Cabinet Table Saws:

Cabinet table saws – given their name due to the totally enclosed ‘cabinet’ type base platform. These kinds of saws represent the other end of the scope compared to the contractor saw. They are meant to match the capability and durability requirements of experienced woodworkers and carpenters.

Cabinet table saws are much more substantial and robust in their all round structure versus contractor saws. They’ve been created with greater trunnions, arbor assemblies, gearing and much more cast iron and steel. They are loaded with more potent huskier motors compared to contractor table saws. This means the cabinet saw is perfect for sawing through thick hard wood with ease, all day long!

There is very little wearing vibrations across the saws positioning and settings.

The cabinet table saw is much more costly than a contractor table saw.

They are not transportable, with a weight of above six hundred pounds. However, even with the higher cost, the power needs, and the hulk of the machine, cabinet saws have become the ultimate desired saw for certified woodworkers/carpenters and serious enthusiasts alike.

Hybrid Table Saws:

Lately businesses have identified that there’s an apparent gulf in class between cost-efficient contractor saws and high-end cabinet saws. It has resulted in a whole new group of saw – The ‘hybrid’ saw.

The hybrid table saw includes several of the most necessary cabinet saw capabilities at a price that may still be in range for a keen beginner hobbyist.

A few hybrid saws possess a more cabinet style foundation and other types possess a small enclosed base and legs. In each case, the base is enclosed, housing the motor inside.

Hybrid saws have more powerful trunnions and arbor bearings and in most cases have got a stronger drive belt system and gearing when compared to contractor saws. The trunnions of hybrid saws are oftentimes attached to the base of the saw, which makes detailed placement of the blade with the miter slot less painful and more enjoyable.

The fact is hybrid table saws are a scaled down adaptation of a cabinet saw. They’re lighter in weight and designed with less powerful motors. They aren’t in reality in the same class as superior cabinet saws, nonetheless hybrids have proven to be stable and well made and can offer several positive aspects to a keen hobbyist.

Choosing the Best Table Saw for Your Needs:

The type of saw that may suit your needs best is based on:

  • Whatever woodworking you perform
  • The time you spend woodworking
  • Your budget and
  • Your own working area as well as the sort of access you’ll have to your working area (for example, think twice before having to move a large cabinet saw into a smallish cellar or basement)

If you simply spend only a few hours per week in your workshop, building small cabinets and working on modest craft-type projects, even though a cabinet saw could be wonderful to have, it is beyond what you’ll need.

Having said that, if you’re managing a nice work shop and so you demand a saw that could run for several hours without hesitation, a low-end contractor saw might slow you down and you’ll wind up being frustrated.

Hybrid saws provide you with flexible options both for dedicated hobbyists and in particular small-scale specialist work shops.

In addition to the type of saw you need, the particular characteristics of the saw are equally as important.

More and more inexpensive contractor saws offer you several of the capabilities that you might find on an excellent cabinet saw.

But don’t forget that while saws within the cabinet saw category share specific characteristics, they are not all produced at the same level of quality. Be aware of the level of a saw’s components, which includes the standard of:

  • The grind and finish of the top and extension wings
  • The fence system
  • The weight and positions of the trunnions
  • The features that make power to the blade stronger

When you buy a table saw you’re making a large investment which means that it is worth thorough consideration. So read through reviews, analyze specifications and check out the good and bad points of any saws you are considering.

Resurrecting an Old Technology – VSR Motors

[ad_1]

A 170 year old electrical technology, called variable switched reluctance (VSR) motors was resurrected in the 1980s with the advent of electronic controllers. The Texas based Le Tiurneau.inc has developed a wheeled front end loader for mining work which use large horsepower VSR motors for its wheel drives. Basically, a VSR motor comprises a rotor and a stator with a coil winding in the stator. The rotor, which consists of a laminated permeable material with teeth, is a passive device with no coil winding or permanent magnets.

The stator typically consists of slots containing a series of coil winding, the energization of which is electronically switched to generate a moving field. When one stator coil is set on, a magnetic flux path is generated around the coil and the rotor. The rotor experiences a torque and is moved in the line with the energized coils, minimizing the flux path. with the approximate switching and energization of the stator coils, the rotor can be encouraged to rotate at any desired torque and speed.

VSR Motors offers the following advantages: Since there are no brushes ringing, there is no requirement of commutator maintenance. the motor is more robust since there are no coils or moving parts. A VSR motor can maintain higher torque and efficiency over broader speed ranges than is possible with other advanced variable speed systems. In addition, as the commutation can be accurately controlled with respect to the rotor angle, the motor will operate at its predicted high efficiency. With VSR technology it is possible to design a low cost motor with over 90% system efficiency and variable speed.

VSR motors can be programmed to precisely match the loads the serve, and their simple rugged construction has no expensive magnets or squirrel cages like the induction motor. VSR motors are smaller than DC motors. VSR motor is inherently resistant to overload and immune to single point failure. They have a high level of fault tolerance and are immune to switching faults. According t a spokesman of Le Tourneau, While the initial cost of SR motor and control is a little more expensive than standard DC system, in the failure, there may be little or no difference in the manufacturing costs due to decreasing prices of electronic components. VSR motors are not without their drawbacks, however. The most significant downside is the acoustic noise and the large vibration caused by the motor’s high pulsating magnetic flux. Another limitation is torque ripple. But while these drawbacks have an effect in small horsepower VSR motors, they are of no significance in large horsepower traction motors.

Energy Saving Tips Using Your Thermostat

[ad_1]

Twenty years ago thermostats were turned up and down for comfort levels with absolutely no thought to saving energy. In fact, the wars over the thermostat are legendary in most families. There is usually one spouse who wants the house over 72 degrees and the other who wants the temperature at least 68.

Today amnesty has been declared! Energy efficient homes and saving money now take precedent regarding where to set the thermostat.

Finding and setting the right temperature is the first goal. The general recommendation is to set the heat at 68 F degrees and at 76 F degrees in the summer. Any time you can either move this number up or down two degrees will give you a substantial cost savings.

For example, if you have your thermostat set at 70 F degrees in the winter and feel comfortable walking around in a short sleeve shirt, you may want to turn the temperature down two degrees and wear a long sleeve shirt and a fleece vest. Setting the air condition at 76 F degrees and turning on the fan is enough to pull out the humidity in the air and keeping it at that level will save energy because the air conditioner will not have to turn on and off.

One quick energy saving tip to keep in mind is that if you are not going to be home for a period of time, whether it is visiting family, taking a vacation, or going to a business trip, Turn you thermostat down in the winter to at least 65-62 F degrees. As long as your furnace is working your pipes will not freeze. If you are leaving during the summer months turn your thermostat to 78. If you live in a climate where there are a lot of insects, keep the air circulating by keeping on the fan.

Programmable Thermostats

If you are serious about saving energy and money your very best decision is to invest in programmable thermostats. They are not too expensive selling at just a bit more than a standard model. However, they can save you money.

For instance, they work the same as other thermostats. When your home temperature changes so much that the furnace or air conditioner needs to kick in, they do the work. However, you can program them to turn on before you come home from work. If you are gone most of the day and there is no one at home, why would you want to keep the furnace blasting all day? If the period of time that you are gone is longer than a couple of hours, these programmable thermostats are a blessing.

You simply set the time in which you will be home and at that time they will kick on. Better models can be programmed for various days of the week such as Saturday when you may be home all day. When the time comes to turn on, they turn on by themselves and get your home at the right temperature.

You can also program them for different temperatures at night when you are sleeping. By raising the temperature in your home during the summer a couple of degrees, or lowering it a couple of degrees in the winter, you are saving a great deal of energy and lowering the cost of your utility bills.

Can You Eat Chicken Eggs Directly From the Coop?

[ad_1]

Can you eat chicken eggs directly from the coop? Absolutely. Fresh eggs from backyard chicken flocks are typically more nutrient-dense and disease-free than the eggs from factory farms sold in most grocery stores today. In fact, fresh eggs from backyard chicken flocks may even be eaten raw or used when still warm from the hen.

To eat your chicken eggs directly from the coop:

  • Make sure your hens are healthy and disease-free; luckily, this is typical with backyard flocks. Chickens with salmonella are notoriously sickly in appearance and generally found only in large factory-farm operations.
  • Wash eggs before using but not necessarily before refrigerating or storing, as washing eggs removes a protective film that keeps the egg fresher for longer.
  • Provide your hens with a clean area for nesting. Spread fresh straw or cedar chips in their nest boxes weekly to keep the eggs clean after they are laid.
  • Collect eggs daily and store them in a cool place.
  • Refrigerate eggs after washing.

The next time someone asks you if you can eat chicken eggs directly from the coop, you’ll know what to say: Yes, of course. Ironically, chicken eggs from small backyard flocks are not only higher in nutrients and far less likely to have any type of disease, they also have better ratios of good cholesterol.

Eating fresh farm eggs is good for your health — and cooking them so the yolk is still runny (or adding them fresh and whole to yogurt smoothies) is the best way to assimilate their nutritive benefits. Raw eggs are not a health hazard if they are fresh and the shells have been washed (use water mixed with vinegar) and dried prior to use, just as a precaution.

Eggs from free-range chickens are also tastier than those from caged hens. The flavor is buttery and good, really not even comparable to store-bought eggs. Backyard hens who have access to grass and bugs in the yard produce eggs with yolks that are a darker, brighter color, nearly orange, compared to the pale yellow of confined birds. These differences are readily apparent to families that have both purchased conventional eggs and raised their own hens.

Once comfortable with the health of your chicken flock, try adding raw egg yolks to smoothies and health shakes for added nutrition. The incredible nutritive benefits from egg yolks are best assimilated raw or close to raw. In addition to raw in yogurt smoothies, try eggs fried in coconut oil, over easy or sunny-side-up and then eaten plain or over toast. This is almost like eating eggs directly from the coop — delicious, and good for your health.

Load Bank Testing To Verify Generator Performance

[ad_1]

Diesel engine power generators are one of the most crucial components of an industrial emergency backup plan. The failure of power generators in emergency situations can lead to disastrous conditions. It is important for companies to monitor and maintain the performance of their power systems. This is where load bank testing comes into play and helps facility managers maintain their power equipment. Load bank testing uncovers potential problems in power generators and enables managers to take preventive measures.

Load bank testing is probably the most effective technique to ensure efficient operations of backup generators. No matter the nature or type of a load bank system, it can not only test the equipment but also improve the overall health of backup units. Load bank testing is a process to:

Verify Cooling System Operation

A load test makes the generator inject additional heat into the cooling air stream. This process will indicate malfunctions in the cooling system. The additional heat created during the process also puts stress on components of a cooling system: thermostat, oil cooler, radiator, etc. We can also obtain valuable data from a testing process that can help us with temperature differential. The temperature data also helps verify backup unit compliance. The process verifies the operations of cooling system alarms such as engine coolant overheat and high cooling water temperature alarm.

Verify Fuel System Operation

Latest diesel engine models are highly turbocharged, which makes them prone to poor combustion at low loads and over fueling. Sometimes power systems do not operate at a load high enough to generate flow velocities and high exhaust temperatures. This situation can lead to issues like wet stacking or accumulation of debris in the exhaust system. These problems can seriously damage the overall performance of a backup system; operation in an unloaded condition or continual use at less than what is the recommended level of load can diminished engine output capacity.

Verify control operation

Power supplies and controls of a generator are sensitive to transients, and, when load changes, can shut down unexpectedly. An inductive or resistive load test is the best way to ensure smooth generator operations. A reliable testing procedure can help uncover many electrical and operational issues such as voltage and frequency adjustments, failed connections, circuit breaker trip settings, and voltage regulator performance. It also provides a best-case simulated real-world condition where efficiency, harmonics, and voltage drop can be studies effectively.

These are some of the benefits of load bank testing. Make sure you are taking good care of your power equipment and generator sets. You can hire a private company to deliver rental load bank testing and preventive maintenance services at your doorstep.

Postnatal ‘Confinement’ Food Part 1

[ad_1]

During pregnancy, the baby is like a parasite and will take all the nutrients that he requires from you. If your diet is sufficient in nutrients for both, it does not cause any problems. If on the other hand your diet is insufficient for both, then your recovery after the birth will take longer and if you still do not replenish your body stores during the confinement period, you may remain weak for a long time. This is probably why our elders make such a lot of fuss about eating well during the confinement period.

Wherever you are in the world, everyone will try and tell you what to eat and if possible how to eat it. The most important thing to do is follow your own body’s needs. Whatever you eat, do make sure that you have a good balance of proteins, vitamins, minerals, fats, carbohydrates, and water in every meal.

Just remember the following pointers:

1. If you are breast feeding whatever you eat will be transferred to your baby via your breast milk therefore it is important that you eat a balanced diet so that your baby will get the right nutrients for optimum growth and development.

2. Some food does cause the baby to become ‘windy’ or have loose stools. If you find that your baby is suddenly quite unsettled, try and think of what you ate during the last 12 hours. Avoid that food for a few days and then try again. If the same happens again, then you should avoid that particular food for a while and re-introduce it into your diet by taking a very small amount and see how baby reacts then slowly increase the amount so that baby gets used to the food.

3. You may find that your appetite is slightly low especially during the first week. This is normal as your body is readjusting to its non-pregnant state both physically and mentally therefore it is better to have small frequent meals instead of the normal 3 big meals a day.

4. You need to drink plenty of fluids in order to make sufficient breast milk and if you are forbidden to drink water, you can get the amount of fluid from other sources such as soup.

So what should you eat?

Most Eastern cultures believe that your body is cold after delivery therefore you should avoid cooling or cold food but eat a lot of yang or ‘heaty’ food to warm the body up. However, if you are normally a yang person, eating too much ‘heaty’ food may cause rashes and fever. In this case it would be better to reduce the amount of ‘heaty’ food and eat more neutral food. If you are normally a Yin person, you should not have any problems eating ‘heaty’ food (lucky devils). The following table gives you a quick review of the types of food to eat or avoid.

Types of food to avoid

‘Cooling food’ for example: banana, cabbage, cucumber, coconut and Chinese cabbage

Contribute to mother’s poor blood circulation and stomach ache in the baby if you are breastfeeding. Salt as a condiment and salty foods in general are to be rejected, too, in the belief that use reduces breast milk production

‘Acidic food’ for example: pineapple, mango, lemon, lime

Contribute to excessive lochia in the mother and diarrhea in the baby.

Too much ‘Heaty food’ for example: chilli, pepper, spices, tonics, spirits and medicines.

Contribute to diarrhea in the baby and maternal headaches

‘Windy food’ for example: jackfruit, tapioca, pumpkin, onions.

Contribute to baby being colicky and may cause indigestion for mother and baby.

Poisonous food such as prawns, shellfish, crab, eel, ginger

Delay healing of the mother’s wound and may cause allergies and eczema in the baby. These foods may cause stomach upsets and vomiting

Type of food recommended

To improve milk production

Chicken, squid, clams (small varieties), fish (especially carp), millet, mutton, pork, rice wine, sea slug, soybean milk mixed with powdered walnuts, wheat cakes, wheat noodles with egg, green papaya

To provide strength to the mother so she recovers quickly from the exertion of labor.

Chicken, frog, Panax ginseng, licorice extract and razor clam

What you eat also depends on what you believe in and who cooks for you. If it is your mother or MIL you may not have many choices. I have seen women quarrelling and not talking to each other because of this issue. Try and work out a compromise which is acceptable to both parties. Use a persuasive and logical approach instead of confrontation.

Several Methods Of Cooling A Transformer In Different Industries

[ad_1]

The transformers are used widely throughout various industries for the conversion of energy at a certain voltage level to the energy at another voltage level. During such conversions and processes, different types of loss occur in the form of heat that also reduces the output power of the device in comparison to the input voltage. The loss varies as the size and capacity of the transformer varies. To withstand this situation, most industries use different methods to dissipate the heat developed during the process and control the losses. These methods are known as the cooling of the transformer which is utterly important if you want to stop the occurrence of loss.

The transformer has in-built oil tank which helps in the process of cooling of both core and windings that is carried through the space between both. There are different ways of cooling a transformer. The coolants are used in the device to dissipate the heat are oil and the air. The heat is either dissolute in the surrounding air or in the oil surrounding the core and windings.

Methods Of Cooling The Transformers Using Air And Oil:-

  • Air Cooling: The heat generated across the core and winding of the device is dissipated from the outer surface of the core and windings to the surrounding air. This method can be classified as the natural air cooling and blast air cooling. In the first method, ambient air is used as the cooling medium where natural circulation of the air dissipates the heat. Another method involves, the circulation of continuous blast of cool air using the external fan without causing any mechanical damage to the device.
  • Oil And Air Cooling: In this method the heat is substantially transferred to the oil surrounding the core and windings. It is conducted through the walls of the device’s tank and finally transferred to the enclosing air by the means of convection and radiation. The benefit of using the method is; it provides better transmission than the first method and high coefficient of conduction results in the natural exchange of the oil.
  • Oil And Water Cooling: As the name of the method suggests, the process typically involves the usage of both oil and the water as the coolant. Along with the oil cooling, the water is circulated through the copper tubes which enhance the overall process. The method is classified as Oil Natural Water Forced and Oil Forced Water Forced. The second method is always preferred over the first one because it is much safer alternative for the oil cooling.

Sub Floor Ventilation – Effective Options Available

[ad_1]

It is always important to ensure that your surroundings are safe and are not a risk to your health. Buildings should always adhere to health and safety standards so that the occupants are free from the risk of disease. An important aspect of buildings that contribute to the health of the occupants is the sub floor ventilation. Proper ventilation will enable you to breathe in fresh air and will also keep termites away which can cause damage to the floor of the building.

Why Sub Floor Ventilation

A sub floor refers to an extra level of flooring that is positioned right on top of the floor joists, and another level of flooring is then placed over it which is the visible floor. A sub floor is usually added to a building so that the floor remains even and flat and also to increase its stability. When air between the floors absorbs moisture from the soil, the humidity of the air goes up which causes the flooring and the framing of the building to also absorb moisture.

Ventilation is therefore important in order to decrease the humidity of the air that is found between the floors. This can be done by replacing the dump air found between the floors with dry air from outside.

Need For Ventilation

Once you realize that your floor has mould and that there is a stale smell in the rooms of your home, then you may be in need of immediate sub floor ventilation. Dampness of the soil usually increases during wet weather, and the moisture easily gets absorbed into the floor and walls of your home. This dampness causes moulds that attract termites which end up destroying your floor.

Moulds can also discolor the tiles of your floor and the bricks that make up your home. Sub floor ventilation is therefore important to in reducing the maintenance costs of your home and also in retaining its value.

Types Of Ventilation

There are different methods that can be used for sub floor ventilation, and how much ventilation will be required will depend on the amount of humidity in that location. The use of air vents is widely used in ventilating the sub floor. This is where air vents are located on opposite sides of the sub floor and air can therefore get in through one side and out through the other.

There should be nothing blocking the movement of the air in and out of the sub floor. To make this system more effective, sub floor fans can be installed to ensure there is proper movement of air. The fans create negative pressure thus causing air to rush in from the vents.

You can decide to have fans which run throughout or ones which are timed. There are also fans which ran on solar energy which means that they do not run when it is cold. Fans should not run when it is wet since the air that comes in will be damp.

Another method of ventilation is compelled ducted ventilation, which causes air to flow freely in areas which are damp and those that are not easily reachable. Damp air is replaced by fresh, dry air from outside. This method uses fans and ducting connected to a power source.
