Split air conditioner is mainly composed of two parts: outdoor unit and indoor unit.
The outdoor unit is responsible for cooling or heating, and the indoor unit is responsible for transporting cold or hot air to the room, and transporting indoor hot or cold air to the outdoors through pipes to achieve the effect of cooling or heating.
The high-temperature and high-pressure refrigerant vapor from the compressor enters the condenser through the high-pressure hose; since the outside temperature is lower than the temperature of the refrigerant entering the condenser, with the help of the condensation fan, most of the heat of the refrigerant flowing in the condenser Carried away by the air outside the car, the high-temperature and high-pressure gas is condensed into a high-temperature and high-pressure liquid. When this high-temperature and high-pressure liquid flows through the throttling expansion valve, due to the throttling effect, the volume suddenly increases and the pressure drops. It becomes a low-pressure and low-temperature mist liquid that enters the evaporator and vaporizes at a constant pressure. The refrigerant vaporizes in the tube. When the temperature is lower than the circulating wind in the car outside the evaporator tube, it can absorb the heat in the air outside the tube, so that the temperature of the air flowing through the evaporator is reduced, thereby producing a cooling effect, and the vaporized refrigerant vapor is compressed The machine sucks and compresses and turns into high-temperature and high-pressure gas, completing a refrigeration system cycle.
