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...
