Multifunctional six-in-one air-cooling heat pump unit

Abstract

The invention belongs to the technical field of refrigeration and air-conditioning, in particular to a multifunction six-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 partial heat regenerator, and a four-way valve, a heat reclaim valve and magnet valves are used for assistance and combined to form six functions: 1, refrigeration; 2, the refrigeration and total heat recovery; 3, the refrigeration and partial heat recovery; 4, independent domestic hot water; 5, heating; and 6, the heating and the partial heat recovery. The heat pump unit is environment-protecting, energy-saving and can be served for multiple purposes.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air-conditioning equipment, in particular to a six-in-one air-cooled heat pump unit with multiple functions of 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...

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

[0006] In the existing technology, the switch between the functions of the unit that can realize one machine with multiple functions is realized by the solenoid valve switch, which is not only expensive, but also the refrigeration system is complicated and the system resistance is reduced, which directly affects the energy efficiency of the system
