How Does Central Air Conditioning Work?

XL15i AC CUTAir conditioners work very similar to another machine in your home, the refrigerator. However Air conditioners doesn't have the outer construction as a refrigerator needs to work as a cold box, AC systems use the walls in your home to keep the cool air in and the hot air out!

Air conditioners run on refrigeration to cool down the air in your house, making use of a remarkable physical law. AC systems preform this attribute of phase conversion by applying specific chemical combination to dissolve and compress over and over again in a sealed system of coils. The combination used are refrigerants that have properties allowing them to adjust at a somewhat low temperatures. Air conditioners also include fans that shift warm inside air over the cold, refrigerant-filler coils. For example central AC's contains of a whole system of ducts arranged to circulate air to and from these winding, air-chilling coils.

At the time where hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside take in the high temperature as it transforms from a fluid to a vaporous condition. To keep the cool effect efficiently, the AC unit has to transform the refrigerant vapor back to fluid again. With the help of a compressor that puts the vapor under high pressure, a method that develop undesirable high temperature. All the added high temperature that is developed by the compressor is cleared to the outdoors by a second set of coils that are named  condenser coils, as well as a second set of fan.

Imagine it as an never ending, sophisticated rotation: fluid refrigerant, turns into gas, high temperature absorbed, compressor turns it back to fluid again.


The Parts of an Air Conditioner

The toughest job an AC unit has to do is to cool down the inside air. But that is not all, Air conditioners also oversees and adjust the air temperature through a thermostat. The Air conditioning unit also has a filter that kills particulates that are floating through the air from breezing into your indoor air. AC's also work as dehumidifiers, considering temperature is an essential element of relative humidity, decreasing the temperature of an amount of humid air results it to release a share of its dampness. That is the reason why there are channels and moisture-collecting containers close to it, or attached to the AC unit, which results in why AC's release water when they run during humid periods.

These are the major parts of an air conditioner that manage refrigerant and circulate air in two directions:

  • Evaporator - Take in the fluid refrigerant
  • Condenser - Takes care of heat transfer
  • Expansion valve - Adjust refrigerant circulation into the evaporator
  • Compressor - A pump that suppress refrigerant

Even though this is a conventional arrangement for an air conditioner system, there are a couple of variations available out on the market. For example larger air conditioners runs a little differently: Central air conditioners has one control thermostat with a the home's AC system, and the compressor and condenser is outside of the house, separated by house walls.  In very large buildings, like hotels and hospitals, the outside condensing Air conditioning unit is often installed and built somewhere on the roof top.
