IN THE BEGINNING:
On July 17, 1902, Willis Haviland Carrier designed the first modern air-conditioning system, launching an industry that would fundamentally improve the way we live, work and play.
Thermostat: Some of us think of the thermostat as an entirely different component but it is actually one of the most important parts of your air conditioner. Your air conditioner's job is to cool the temperature, but how will it know when to start and stop unless the temperature is being monitored? Making sure your thermostat is working correctly and up to date is an important part of an efficient air conditioner.
Evaporator: Air conditioners use a chemical compound known as refrigerant to cool the air. The evaporator is the part or your air conditioner that receives the liquid refrigerant.
Condenser: The condenser facilitates the heat transfer in your air conditioner.
Expansion Valve: The expansion valve regulates the flow of refrigerant into the evaporator of an air conditioner.
Compressor: The compressor works as a pump that pressurizes the refrigerant in your air conditioner.
HOW IT WORKS:
The most common setup of an air conditioner is called the "cold side" and the "warm side." On the cold side is the evaporator that houses the refrigerant. It includes the fan that pulls the warm air in and blows it over chilled coils. The hot side of the air conditioner contains the compressor, the condenser and an additional fan that takes the hot air from the compressor to the outside. In central air systems, the condenser and compressor are housed in the outside part of the unit. In the middle of both sides of the air conditioner sits the expansion valve that regulates the amount of liquid refrigerant flowing into the evaporator. As the refrigerant moves into the evaporator, the pressure drops and it turns into a gas. Then the compressor works like an electric pump to cause pressure and turn the gas back into liquid.
Remember, there are all sorts of little parts like valves, sensors and timers, but these four parts of your air conditioner are the largest and cause the most trouble when there is a breakdown.
Understanding a little more about how your air conditioner works can be very helpful if your HVAC technician is explaining a current problem you are experiencing or a future problem that you can prevent.
