Classification and working principle of the air source heat pump

An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source air to a high-level heat source. Next, we will describe how many types of air source heat pumps there are and how they work.

Classification of air source heat pumps

1、According to the type of compressor, air source heat pumps can be divided into fully enclosed and semi-hermetic piston compressors, scroll compressors, semi-hermetic screw compressors, etc.

2、According to the size of the unit capacity, air source heat pumps can be divided into villa-type small units and medium and large units.

3、According to the structure of the unit, air source heat pumps can be divided into an integral unit and a modular unit.

4、According to the function, air source heat pumps can be divided into general heat pump units, heat recovery units, and storage heat units.

Working principle of air source heat pumps

1、The air-water heat pump works according to the inverse Carnot principle, namely the principle of the inverse Carnot cycle. Through the operation of the compressor system, the air source heat pump absorbs heat from the air to produce hot water. The specific process is as follows. The compressor compresses the refrigerant. The compressed refrigerant increases in temperature and passes through the condenser in the water tank to produce hot water. After the heat exchange, the refrigerant returns to the compressor for the next cycle. The air heat is absorbed into the refrigerant through the evaporator. The refrigerant is then introduced into the water to produce hot water. The new generation of water heaters through the compressor air heat, that is, the heat pump water heater. Figuratively speaking, it is the outdoor unit that compresses air like a pump to raise the air temperature. Then the heat is transferred to the indoor storage tank through a liquid that boils at -17°C. The heat is then released and transferred to the water.

2、Air water heat pumps use the working principle of heat pumps to produce heat. According to the principle of heat balance, the air source heat pump produces at least 2,800 watts of heat at the same time, plus the input of 1,000 watts of electricity, the actual heat produced is 3,000 to 4,000 watts, and the heat pump delivers this heat to the thermal tank. Its power consumption is only a quarter of that of an electric water heater.

3、Water heaters using inverter air source heat pumps do not need sunlight, so they can be placed at home or outdoors. There
