Abstract

A parallel modular heat pump unit, including a first dry pipe, a second dry pipe, a third dry pipe, and a compressor connected to the second dry pipe and the third dry pipe at both ends; At least two identical modules are connected in parallel on the second main pipe and the third main pipe, and the modules include the first heat exchanger, the first one-way valve, the first electronic expansion valve, the first four-way valve and the first three-way valve ; The first one-way valve is connected in parallel with the first electronic expansion valve, and the three ports of the first three-way valve are respectively connected to one end of the first four-way valve, the second dry pipe and the third dry pipe; the first four-way The four ports of the valve are respectively connected to the first dry pipe, one end of the first heat exchanger, one end of the first three-way valve, and a parallel end of the first one-way valve and the first electronic expansion valve; the first heat exchange The other end of the device is connected to the other parallel end of the first one-way valve and the first electronic expansion valve. The invention can supply cooling and heating at the same time, the whole system is flexible and multi-purpose, improves the comprehensive COP, and saves energy.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to a multi-purpose parallel 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 cond...
