PRINCIPLE OF OPERATION
After the power supply is switched on and the machine is set to COOL mode, with the compressor being
operating, the low-temperature and low-pressure refrigerant vapor is sucked into it and then compressed
into high-temperature, high-pressure gas. The gas is cooled into liquid by the air through the outdoor
heat-exchanger. The liquid comes into the indoor unit after being throttled by the capillary. The
refrigerant in the indoor heat-exchanger evaporates, absorbing heat and reducing the room temperature.
The evaporated refrigerant vapor then returns to the outdoor unit where it is sucked into the compressor
again and discharged from the same after being compressed. By cycling in this manner, the purpose of
reducing the room temperature is fulfilled.
After the power supply is switched on and the machine is set to HEAT mode, the coil of the reversing
valve is energized. With the compressor being operating, the high-temperature, high-pressure refrigerant
vapor discharged from it first comes to the heat exchanger of the indoor unit where it is cooled, releasing
heat and making the room temperature rise. The cooled high-pressure refrigerant is throttled in the
outdoor unit and returns to the compressor after evaporation. By cycling in this manner, the purpose of
increasing the room temperature is fulfilled.
