An air conditioner(AC) is tasked with changing the temperature, then general quality of air, and or the humidity. Specifically, an AC makes your home air cooler, by removing heat energy out of your home and then transferring the heat energy to the outside, it then replaces the air inside your house with air that is conditioned and cool.
HOW IT WORKS
The AC portion in a central HVAC system circulates cool air through the ducts inside your house, by providing a system that removes the heat from the warm air inside the home. In your basic split system, the HVAC compressor condenses and moves a chemical refrigerant through the outdoor condenser unit, which changes the composition of the refrigerant from a gas to a liquid form. This liquid refrigerant is then pushed through the indoor evaporator coil. The indoor AC unit has a fan that circulates the inside air to move aross the fins of the evaporator coil. The evaporator’s fins which are usually metal, exchanges the thermal heat energy with all of the air around it. The, liquid refrigerant is then transformed into a vapor, removing any heat from the surrounding air. The process removes the heat from the air and the cooled air is then circulated back around the house.
The outdoor unit or condenser then turns the chemical refrigerant vapor back to a liquid form, which removes the heat. By this time the refrigeration fluid leaves the evaporator coil again, it is now a cool, low pressure gas, which eventually returns to the outdoor condensor to start the process all over again. This process continues over & over until your house reaches the temperature your thermostat senses. And that’s it in a nutshell.
