Abstract

The invention discloses a multifunctional split water ring heat pump unit, which includes a compressor, a total heat recovery device, a first four-way valve, a second four-way valve, a ground source heat exchanger, a one-way valve, a solenoid valve, a storage Liquid tank, electric expansion valve, terminal heat exchanger. The outlet end of the compressor is connected to the total heat recovery device, the total heat recovery device is connected to the first port of the first four-way valve, and the fourth port of the first four-way valve is connected to the ground in turn. A source heat exchanger, the liquid reservoir, the electric expansion valve, the solenoid valve, and the terminal heat exchanger, the terminal heat exchanger is connected to the first port of the second four-way valve; the The fourth port of the second four-way valve is connected to the second port of the first four-way valve; the inlet port of the compressor is connected to the second port of the second four-way valve, and the port of the first four-way valve is connected to the second port of the second four-way valve. The third port is connected to the second port of the second four-way valve; the one-way valve is connected between the 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...
