Several Types of Air Conditioners

By Marie Alvarez


Air conditioners are considered to be appliances that modify the air in a room to provide human comfort. Air conditioning involves heating a cooling air. There are lots of types of air conditioning units available. Several air conditioners cool the air making use of refrigerants while some heat the air using oil, electrical power or other types of fuels. The following are a few of the different kinds of air conditioners available on the market.

Through Wall Air Conditioners

Among the different kinds of air conditioning units are through wall air conditioners. These air conditioners are fitted through an opening on the wall and have got interior components and exterior components. This type of air conditioning unit works by cooling the interior air over an evaporator. On the outside the air conditioner condenses the air from the inside over a condenser and fans it out of the room. This creates a temperature gradient making heat move out of your room to the outside. A number of these air conditioners could be installed in a building to cool different rooms. These air conditioning units are great because they allow rooms to be cooled independently thus occupants could cool a place to their wanted temperatures without affecting in different rooms.

Evaporative Air Conditioners

Evaporative air conditioners are the types of air conditioners utilized in dry climates. An evaporative air conditioning unit brings in air from the outside thru a wet pad drenched in water. The air being drawn in significantly decreases its temperature. Whenever the outside air is really dry, evaporative coolers have got a significant cooling effect which gives comfort to dwelling occupants. Nevertheless when the exterior air is humid evaporative coolers provide no change at all and could be thought to be inefficient in humid climates. Evaporative air conditioners are wonderful because they're cheap and simple to maintain.

Transportable Air Conditioners

Portable air conditioners are air conditioners that are on wheels and can very easily be relocated within a building. These kinds of air conditioning units are obtainable either as evaporative coolers or as refrigerative chillers. The refrigerative type works in the same manner as a through the wall air conditioner. It dehumidifies the air and cools it. Hot air is created along the way that has to be blown out. By blowing warm air outside the air conditioner makes a temperature gradient that causes the air within the place to cool. The evaporative air conditioning units don't have a compressor or condenser. They work by releasing water on cooling fins as well as the vapor cools the room.

Heat Pumps

Heat pumps are different kinds of air conditioning units which reverse the refrigeration cycle and produce heat instead of cooling the air. They're also called reverse cycle air problems. Heat pumps are preferred to using electric resistance heaters as they make use of less energy and are eco-friendly. Heat pumps are suitable for use in mild winter temperatures otherwise they are inadequate against very low temps because of formation of ice on the heat exchanger coil. Heat pumps are usually affordable and easy to maintain.
