Example Embodiment

[0038] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0039] reference image 3 As shown, a multifunctional split water ring heat pump unit in this embodiment includes an indoor unit and an outdoor unit. The outdoor unit includes a compressor 1, the indoor unit includes a total heat recovery device 2, a first four-way valve 3, and a ground source changer. Heater 4, accumulator 5, electric expansion valve 6, solenoid valve 7, one-way valve 8, end heat exchanger 9, second four-way valve 10.

[0040] The outlet end of the compressor 1 is connected to the total heat recovery device 2, the other end of the total heat recovery device 2 is connected to the first port a1 of the first four-way valve 3, and the four port d1 of the first four-way valve 3 is connected to the ground source heat exchanger 4. In this way, the ground source heat exchanger 4 is connected to one end of the accumulator 5, the electric...

Abstract

The invention discloses a multifunctional split water-loop heat pump unit comprising a compressor, a total-heat recoverer, a first four-way valve, a second four-way valve, a geothermal exchanger, a one-way valve, a solenoid valve, a liquid reservoir, an electric expansion valve and a tail-terminal heat exchanger. An outlet end of the compressor is connected with the total-heat recoverer that is connected with a first port of the first four-way valve, a fourth port of the first four-way valve is connected with the geothermal exchanger, the liquid reservoir, the electric expansion valve, the solenoid valve and the tail-terminal heat exchanger sequentially, the tail-terminal heat exchanger is connected with a first port of the second four-way valve, a fourth port of the second four-way valve is connected with a second port of the first four-way valve, an inlet end of the compressor is connected with a second port of the second four-way valve, a third port of the first four-way valve is connected with a second port of the second four-way valve, and the one-way valve is connected between a third port of the second four-way valve and the electric expansion valve.

Description

technical field [0001] The invention relates to the technical field of heat pump units, in particular to a multifunctional split water ring heat pump unit. Background technique [0002] The basic working principle of the water loop heat pump air conditioning system is: when the water / air heat pump unit is heating, the water in the water circulation loop is used as the heating source; when the unit is cooling, the water is used as the heat exhaust source. [0003] Existing commonly used total heat recovery systems such as figure 1 As shown, including expansion valve, condenser, four-way valve, total heat recovery device, compressor, and evaporator. The heat of this system will not attenuate during cooling and heating, but the heat will attenuate when making domestic hot water. This is because the refrigerant is not supercooled after passing through the heat recovery device, resulting in "refrigerant flash before the valve" , so that the heating capacity is attenuated, and t...
