When the air conditioner of the heat pump type quality Explosion Compressor suppliers china operates in the heating condition, the four-way valve reversing makes the dotted line in the figure connected. At this time, the indoor heat exchanger of quality Explosion Compressor suppliers 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 enters the gas-liquid separator through the four-way valve and the muffler. After the liquid is separated, the dry superheated gas is inhaled and compressed by quality Explosion Compressor suppliers china to become high temperature and high pressure gas. 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 quality Explosion Compressor suppliers china from defrosting the air conditioner during heating, the indoor comfort is reduced, and the hot air bypass uninterrupted heating and defrosting method is 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 quality Explosion Compressor suppliers china is shunted to the inlet of the outdoor heat exchanger, which quickly raises the temperature of the outdoor heat exchanger to above 0°C and melts the frost layer on the outdoor heat exchanger. Make the heat exchanger maintain good heat exchange efficiency.
Through the above introduction and analysis of the Heating Engineering Principles of the Quality Explosion Compressor suppliers china, hope it helps you.
