How does air conditioning work?
An air conditioner can transform the temperature, humidity or general quality of the air. More specifically, an air conditioner makes your home a cold or warm comfortable place, by drawing heat energy out of the house and transferring that heat to the outdoors, then replacing the air inside your home.
How do split wall and ducted air conditioners work?
The air conditioner in a ducted heating and cooling system delivers cool air across ductwork inside your home, by providing a process that draws out the warm air inside, removing its heat.
In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, shifting it from a gas to a liquid. The liquid is then forced through the indoor evaporator coil. The indoor unit’s fan circulates the inside air to pass across the evaporator fins. The evaporator’s metal fins exchange the thermal energy with the air around it. There, the refrigerant turns from liquid into vapour, eliminating any heat from the surrounding air. As the temperature is taken out from the air, the air is chilled and carried back into the house.
From that point, the outdoor unit then turns the refrigerant vapour back into a liquid, eliminating any heat. By the time the liquid leaves the evaporator again, it is a cold, low-pressure gas, eventually returning to the condenser to start the trip all over again. This process continues until your home reaches the programmed desired set temperature and detected by your thermostat.
