What are the different parts of an air conditioner?
A standard air conditioner has four major parts: evaporator, condenser, expansion valve, and compressor. Not only do air conditioners cool the indoor air, they also monitor and regulate the temperature of the indoor air with a thermostat. Filters remove airborne particulates from the air. Air conditioners also function as dehumidifiers. When the air outside is humid, an air conditioner will discharge water. More on that at http://frankweglarzhvac.blogspot.com/.
The evaporator receives the liquid refrigerant. The condenser takes the heat from the inside to the outside. The expansion valve regulates the flow of the refrigerant into the evaporator, and the compressor pumps the refrigerant. Frank goes into more detail about what this means for your home on his website https://iamfrankweglarz.wordpress.com/.
Think of an air conditioner as having two sides: a cool side and a hot side. The evaporator is on the cold side of the unit and with the use of a fan, blows air over the chilled coils releasing cool air into a room. The hot air is on the other side along with the compressor and condenser. In between these two sets of coils is an expansion value. Once here, the evaporator drops the pressure changing the refrigerant gas into a gas allowing the heat to escape. The compressor is actually a large pump that puts pressure on the refrigerant gas in order to turn it into a liquid so it can return inside and cool the air once again.
