Multi-functional modularization heat pump machine set

Abstract

A multi-functional modularization heat pump machine set comprises a compressor, an electronic expansion valve, four main pipes which are a first main pipe, a second main pipe, a third main pipe, a fourth main pipe, and at least two same modules which are connected with the compressor and the electronic expansion valve in parallel and arranged on the four main pipes, wherein the modules comprises a first heat exchanger, a first three-port valve and a second three-port valve, wherein three ports in the first three-port valve are respectively connected with one end of the first heat exchanger, the first main pipe and the second main pipe; the three ports in the second three-port valve are respectively connected with one end of the first heat exchanger, the third main valve and the four main valve. The machine set can simultaneously supply cold and heat, causes that each heat exchanger can be both a condenser and an evaporator; namely, the heat exchanger becomes the heat-producing or cold-producing operation condition from the cold-producing or heat-producing operation condition without changing the cold-producing or heat-producing operation condition of other heat exchangers.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to a multi-connected heat pump unit with multiple functions. 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...

AI Technical Summary

Problems solved by technology

However, the functions are small, and it cannot realize the function of cooling or heating by any heat exchanger, nor can it recover the cooling capacity, but can only recover the heat; and it cannot achieve the modular effect like the multi-line, which limits its application.
