Explanation of How Split System Air Conditioners Work
Split system air conditioners are a popular choice for cooling homes and offices. They consist of two main components: an outdoor unit (the condenser) and an indoor unit (the evaporator). The two units are connected by refrigerant pipes and electrical wires.
The outdoor unit houses the compressor and condenser coil, while the indoor unit contains the evaporator coil and blower fan. When the air conditioner is turned on, the compressor pumps refrigerant to the outdoor unit, where it absorbs heat from the indoor air.
The refrigerant then flows back to the indoor unit, where it releases the heat and cools the air. The cool air is then distributed throughout the room via the blower fan. This continuous process keeps the room cool and comfortable.
