Description

Technical Field

[0001] The present application relates to the technical field of heat pump water tanks, and in particular to an air energy heat pump water tank and a method of using the same. Background Art

[0002] With the development of economy, people's requirements for quality of life are getting higher and higher. People's requirements for showering are getting higher and higher. Gas water heaters, electric water heaters, and solar water heaters are far from meeting people's needs for comfort, energy saving and safety. Air-to-air heat pumps use the heat in the air to generate heat energy. They can provide the whole family with different hot water, heating and cooling needs with large water volume, high water pressure and constant temperature 24 hours a day, while meeting the above requirements with the least energy consumption.

[0003] The air energy heat pump works according to the "reverse Carnot" principle, the reverse Carnot cycle principle. The compressor system works by absorbing heat from the air to produce hot water. The specific process is: the compressor compresses the refrigerant, and the refrigerant with a higher temperature after compression passes through the condenser in the water tank to produce hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the heat of the air is absorbed by the evaporator and introduced into the refrigerant, and the refrigerant is then introduced into the water to produce hot water. The new generation of water heaters that heat air through compressors is the air energy heat pump water heater. Figuratively speaking, the "outdoor unit" compresses the air like an air pump to increase the air temperature, and then conducts the heat to the indoor water tank through a liquid that boils at -17°C, and then releases the heat and conducts it into the water.
