Four-in-one air-cooling heat pump unit

Abstract

The invention belongs to the technical field of refrigeration and air-conditioning, in particular to a four-in-one air cooled heat pump unit for refrigeration, heating and domestic hot water. A water side heat exchanger and an air side heat exchanger can be used as a condenser or an evaporator, a regenerator can be used as the condenser, and a four-way valve and magnet valves are used for assistance and combined in one direction to form the air cooled heat pump unit with four function, and the four functions are: 1, refrigeration; 2, the refrigeration and total heat recovery; 3, independent domestic hot water; and 4, heating. The heat pump unit can realize the total heat recovery of the hot water during the refrigeration. The hot water produces heat without any expenses. The heat pump unit can produce the hot water all the year around to solve the problem that a use side of an air conditioner cannot produce the hot water when not being used.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning equipment, in particular to a four-in-one air-cooled heat pump unit for refrigeration, heating and domestic hot water. Background technique [0002] At present, the known air-cooled heat pump unit basically only has two functions of cooling and heating; part of the heat recovery unit of the air-cooled heat pump unit has refrigeration, heating and a small amount of domestic hot water; the air-cooled hot water unit can only produce hot water. [0003] The air-cooled heat pump unit with only two functions of cooling and heating cannot produce domestic heat, especially the heat generated by the air conditioner during cooling is wasted, resulting in a lot of energy waste. [0004] Part of the heat return air cooling heat pump unit can only recover a small amount of heat, especially in the cooling process, most of the heat generated by the air conditioner is wasted, which also...

AI Technical Summary

Problems solved by technology

[0003] The air-cooled heat pump unit with only two functions of cooling and heating cannot produce domestic heat, especially when the heat generated by the air conditioner is wasted during cooling, resulting in a large amount of energy waste

[0004] Part of the heat return air cooling heat pump unit can only recover a small amount of heat, especially in the cooling process, most of the heat generated by the air conditioner is wasted, which also causes a lot of energy waste; at the same time, some heat return air cooling heat pump units When it is hot), hot water cannot be produced, and it cannot meet the requirements of general domestic hot water throughout the year

[0005] The air-cooled hot water unit can provide domestic hot water throughout the year, but it cannot produce cooling capacity. The cooling capacity generated by air conditioning in summer is wasted, resulting in a lot of energy waste
