What Makes My Air Conditioner Work?

Air conditioning is a relatively new technological invention that many homeowners take for granted. Many of us do not even consider how our systems work until they need repairing or replacing. Understanding what makes an air-conditioning system work and how the various parts function, however, is an excellent way to spot potential problems before they become too serious.

What Makes an Air Conditioning System Work?

First important thing to note is that Air Conditioning is a component of your Heating and Air Conditioning (HVAC) system. The system absorbs heat from the inside of your home through the evaporator (box generally attached to the top of your heater) and disposes of that same heat outside of your home through the condenser (box that blows hot air outside of your home).

How Cool Air is Produced

While air conditioning systems work through evaporation, there are many parts that play key roles. Outside your home we will start with the condensing unit, because it’s the starting and stopping place for your system. The compressor a component in that unit should be considered the heart in the refrigerant system. Just like your heart it moves its blood (refrigerant) throughout the system. No heart no life, no compressor no cooling. The compressor like its name says compresses the refrigerant into a high temperature high pressure vapor. This vapor now moves through the condensing coil where it is cooled using the outdoor fan, to the point that it condenses into a high temperature high pressure liquid.

This liquid refrigerant travels through the copper piping to the inside of your home till it reaches the evaporator coil (the evaporator coil is located just above your heater in a box.) The liquid refrigerant is forced through a metering devise which causes the refrigerant to drop in pressure and starts to flash back into a low temperature, low pressure vapor. The vapor travels through the coil where the fan in the heater forces the air drawn from your home to pass over the outside of the aluminum fins of the coil (the refrigerant and the air never physically touch.) Since heat is drawn to cold the refrigerant absorbs the heat from the air. The humidity or moisture condenses on that cold coil and drains out at the condensate pipe. The refrigerant now returns back through the copper piping to the condensing unit and back into the compressor to start all over again. This process continues until the temperature that you have set on your thermostat is met.
