Air Conditioning

Air conditioning, ventilation, and heating are the science of vehicular and indoor environmental comfort. Its objective is to offer comfortable indoor air quality and thermal comfort. An air conditioner, as the name suggests, cools a room by releasing heated or cooled air into the room through a refrigerant. This is usually a refrigerant gas like propane, but can be a liquid such as ethylene glycol or some combination thereof. A duct system and a condenser collect the cooled or heated air from the interior of the unit and transports it out of the room.


The cooling system inside an air conditioning unit from this pageincludes the evaporator that condenses moisture on the outside of the unit and transfers it into outdoor air through a condenser coil and then it returns the cooled or heated air to the room by way of a duct. A fan in the exterior part of the unit draws air into the exterior chamber of the unit and is then discharged through the exterior vent.


In most places, air conditioning can be used to help lower the temperature in the home during the hot summer days or in cold weather. Most air conditioners are designed to be very effective at reducing heat related illnesses like bronchitis, emphysema, and allergies. Air conditioners also help keep rooms cooler on days when the weather is too hot. Know more about HVAC at http://www.ehow.com/how_5458851_repair-home-air-conditioners.html


Air conditioning systems that run on electricity typically use a refrigerant gas to chill the inside of the building. There are two types of electric air conditioners - one which heat air before circulating it throughout the building, and the other that circulates the heat into air vents before it is delivered into the room. In both cases, the air that is circulated is still chilled. These types of air conditioners are commonly installed by building managers.


Many people believe that it is a good idea to have an air conditioner installed in all rooms in a house; however, this may not be practical, especially if the room has limited space. If the room is not too large, it may be possible to get away with having a central air conditioner that only cools the main rooms in a house.


In the colder months, it is usually necessary to have indoor air conditioning systems installed for people who work outside to keep their indoor air comfortable. In areas where there is high humidity, it is also a good idea to have the air conditioning systems in the home running to reduce the humidity level inside the building. Air conditioning systems can also be helpful in maintaining healthy indoor air quality by controlling the amount of pollutants and cleaning up smoke and dust particles that are airborne. In addition, air conditioners help increase comfort by increasing the temperature in a room while reducing the humidity level, thereby helping to keep a room more comfortable. Start now!
