Qatar outdoor air conditioner removes heat, and dispels indoor hot air when air conditioner cools. When the air conditioner is used for refrigeration, it is a system, not a component, which dissipates the hot air in the room. Refrigerant (Freon) absorbs heat when the pressure decreases and releases heat when it is pressurized. In fact, any gas has this characteristic, including air, but freon has a better effect. The evaporator of the indoor unit of the air conditioner is the decompression process of refrigerant, which will release cold air. Since the cold air is released, it will absorb heat. The absorbed refrigerant is sent to the outdoor unit through the low-pressure pipe (thick pipe) and pressurized by the compressor, which will release heat. The outdoor unit has a condenser, which will radiate the heat of the pressurized refrigerant through the condenser of the outdoor unit, and then transfer it to the indoor unit to decompress and release cold air, thus completing a cycle.
