Air/water source heat pump unit

Abstract

The invention discloses an air / water source heat pump unit which is capable of adapting to the environment with lower temperature to work, and comprises a condenser, a compressor, an evaporator, an expansion valve, a filter and a liquid storage tank, wherein the condenser, the compressor, the evaporator, the expansion valve, the filter and the liquid storage tank are sequentially connected in series, so that a system can be formed; and a solar thermal collector is connected between the compressor and the evaporator in series. As a structure that the solar thermal collector is connected between the compressor and the evaporator in series is adopted by the air / water source heat pump unit, refrigerant gas which flows out from the evaporator and obtains the air / water source energy flows through the solar thermal collector, the heat energy is transmitted into the compressor, more higher energy can be obtained by the refrigerant working medium in the compressor, and the refrigerant working medium is rapidly and efficiently evaporated to be gas. After the solar thermal collector is adopted, the reliable circulation of the unit can be guaranteed, so that the heat pump unit can be used for heating in the season of severe winter in most parts of the north.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to a heat pump unit utilizing heat energy in air or water source. Background technique [0002] With the rapid development of the economy, human production and life have more and more trust and demand for energy, but most of the energy is non-renewable, and the energy on the earth will become less and less. For this reason, human beings are constantly looking for new energy sources to replace traditional energy sources. At the same time, the research on energy-saving technologies is getting deeper and deeper. In recent years, some new energy-saving technologies have been successfully developed, such as air / water source heat pump unit is one of them. The air / water source heat pump unit uses the low-level heat energy of the air or water source to perform work through the machine and electricity, so that the energy is transferred from the low-level heat source to the high-level heat source, which c...

AI Technical Summary

Problems solved by technology

The energy efficiency of heat pump units in the vast north of my country is greatly reduced in winter. The main reason is that the refrigerant working medium in the compressor is affected by the environment and the temperature is low, so it cannot work normally, which seriously affects the heating effect.
