When the air conditioner of the heat pump type Discount Explosion compressor prices china operates in the heating condition, the four-way valve is reversed so that the dotted line in the figure is connected. At this time, the indoor heat exchanger of Discount Explosion compressor prices china becomes the condenser, and the outdoor heat exchanger becomes the evaporator.

The low-temperature and low-pressure superheated gas from the outdoor heat exchanger enter the gas-liquid separator through a four-way valve and a muffler. After the liquid is separated, the dry superheated gas is sucked and compressed into a high-temperature and high-pressure gas by Discount Explosion compressor prices china. The through valve enters the indoor heat exchanger to release heat and condense (at this time, the indoor air is heated) and becomes a subcooled liquid.
The supercooled liquid becomes a low-temperature and low-pressure two-phase fluid after being depressurized by capillary resistance. It enters the outdoor heat exchanger to evaporate and absorb heat, and then the superheated gas enters the next cycle through the four-way valve and the gas-liquid separator. In order to prevent the decrease in indoor comfort caused by defrosting the air conditioner during heating, the hot gas bypass uninterrupted heating and defrosting method are adopted. When defrosting, the operating principle is basically the same as heating, except that the defrosting solenoid valve is turned on.
Part of the high-temperature and high-pressure superheated gas from Discount Explosion compressor prices china is shunted to the entrance of the outdoor heat exchanger, rapidly raising the temperature of the outdoor heat exchanger to above 0°C, and melting the frost layer on the outdoor heat exchanger, Keep the heat exchanger with good heat exchange efficiency.
Through the above introduction and analysis of the Engineering Principle of Heating the Discount Explosion compressor prices china, hope it helps you.
