Abstract

The invention provides a modularized heat pump unit, comprising a compressor, an electronic expansion valve and at least two modules which are parallelly connected between the link-loops of the compressor and the electronic expansion valve; each module comprises a first three-way valve, a second three-way valve, a first electromagnetic valve, a second electromagnetic valve and a heat exchanger, the three ports of the first three-way valve are respectively connected with one end of the first electromagnetic valve, the second electromagnetic valve and the heat exchanger, and the three ports of the second three-way valve are respectively connected with the other end of the first electromagnetic valve, the second electromagnetic valve and the heat exchanger; the two ends of the first electromagnetic valve and the second electromagnetic valve are respectively connected between the link-loops of the compressor and the electronic expansion valve. With the invention adopted, each heat exchanger in each module can be a condenser or an evaporator, and the exchanger can be changed from a refrigerating / heating working condition into a heating / refrigerating working condition without changing the refrigerating or heating operation working conditions of other exchangers, thus improving the comprehensive refrigerating efficiency of the system, saving energy and satisfying the requirements of different customers.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to a multi-purpose modularized heat pump unit. Background technique [0002] In the past, people mainly used single evaporator systems for heat pump units, such as figure 1 As shown, during cooling operation, the compressor 100 sucks the low-pressure and low-temperature refrigerant vapor generated in the evaporator 101 to maintain the low-pressure state in the evaporator 101 to create conditions for the refrigerant liquid in the evaporator 101 to boil at low temperature. The vapor sucked by the compressor 100 is compressed, and the pressure and temperature are increased, so that the refrigerant can be liquefied at normal temperature. After the high-pressure and high-temperature refrigerant vapor is discharged from the compressor 100 into the condenser 102, it is cooled by the cooling medium under the condition of constant pressure, releases heat, lowers the temperature, and finally condenses int...
