About

When you say cooling systems you first think of air conditioning, but there are many other inexpensive cooling ways that can provide better cooling with less energy. Air conditioners can use a lot of electricity on hot summer days. According to specialists, heating and cooling systems emit over a half billion tons of carbon dioxide into the atmosphere each year, adding to global warming.

Ventilation

One of the best and inexpensive cooling systems is ventilation which is used to maintain a healthy living environment by supplying fresh air to your home while at the same time removes stale and polluted air. Ventilation also helps to maintain suitable humidity levels of 30 percent to 50 percent.
The air in your home is used many times over, sometimes with fresh air entering only when you open doors or windows. As long as we struggle to build homes more and more energy efficient we create an environment prone to indoor air quality problems, and by reducing the house capability to breath natural air changes do not occur. Another important aspect of using ventilation is that it can help reduce allergy and asthma symptoms and other respiratory problems.

Air conditioning units

Air conditioning is probably the most efficient of all cooling systems available on the market.
There are many types of air conditioning units ranging from a small room air conditioner to a large central air conditioning unit. New generation of air conditioning units are available on market and they are much more efficient than earlier models providing you the possibility of energy saving.

Evaporative cooling

If you live in a dry climate evaporative cooling is certainly a good way to cool your place. Known as swamp cooling these types of cooling systems offers the same experience like an air conditioning unit but with less energy consumption. These evaporative coolers continually use water and that is why they are not meant to be used in areas with limited water supplies.

Other cooling systems

There are other cooling options available like absorption coolers which use heat instead of electricity as their energy source, and they are now available for big houses. Another efficient cooling system is radiant cooling which can work best in arid climates. There are also earth cooling tubes which have been already installed in some houses, but these types of cooling systems are not very efficient.

About

If there is not enough fresh air inside a room, pollutants can sometimes accumulate to levels that can cause health and comfort problems. By using ventilation fans you can lower the concentrations of indoor air pollutants in your home by increasing the amount of outdoor air coming in.
Nearly all home cooling systems as well as forced air heating systems, do not mechanically bring fresh air into your house. Opening windows and doors, operating window or attic ventilation fans, when the weather permits, or running a window air conditioner with the ventilation control open increases the ventilation rate. Local bathroom or kitchen ventilation fans that exhaust outdoors remove contaminants and pollutants, including moisture, directly from the room where the ventilation fan is located and also increase the outdoor air ventilation rate.

Why ventilation fans

Ventilation fans are an excellent way to ventilate your entire home efficiently, and cheaply.
A ventilation fan is a motorized ventilation device that helps to draw out stale and impure air from your home and bring in fresh air and improve the quality of indoor air.

Types of ventilation fans

Ceiling mounted ventilation fans
Ceiling ventilation fans are those which are installed in the ceiling. These fans push out stale air from your home upwards through the roof.  The ventilation fan is connected to ducting, which is exhausted outside the house through an external vent, like a roof cap or soffit exhaust vent.

Wall mounted ventilation fans
These types of ventilation fans are installed directly on exterior walls. Because they are installed on exterior walls of the home and not on interior walls, the stale air has a direct route to the outside of your home and no ducting work is needed when installing these ventilation fans.

Exterior remote mounted ventilation fans
These types of exterior remote mounted ventilation fans are installed outside your house and drag out stale indoor air instead of pushing it out like others ventilation fans which are installed inside.
Exterior remote mounted ventilation fans are very noisy but the noise remains outside because they are installed outside your house.
