System for efficiently utilizing afterheat and circulating multiple refrigerants

Abstract

The invention discloses a system for efficiently utilizing afterheat and circulating multiple refrigerants, comprising a compressor, a solar ejector, a condenser, a solution circulating system, a gas-liquid separator, a throttle valve, an evaporator, and a four-way reversing valve. The condenser, the evaporator, the compressor, and a solar ejection compressor are all connected to the four-way reversing valve; the compressor is connected with a main inlet of the solar ejection compressor by means of a refrigerant pipe; and the solar ejection compressor is provided with two outlets, is connectedwith the four-way reversing valve by means of one outlet, and is connected with the solution circulating system by means of the other outlet. The system has the beneficial effects that diversified utilization of energy can be implemented by means of utilization of afterheat and waste heat in the solution circulating system and utilization of solar energy; and a two-stage compression system composed of two systems can also reduce the power required by the compressor, so that the energy is further saved.

Description

technical field [0001] The patent of the invention relates to an air-conditioning and refrigeration system, in particular to a high-efficiency utilization of waste heat and a multi-refrigerant circulation system. Background technique [0002] With the development of economy and society, the use of refrigeration equipment such as air conditioners is increasing day by day, and its total amount is growing rapidly. Most of the refrigeration systems we currently use are vapor compression refrigeration systems, because vapor compression refrigeration systems have many advantages, such as compact structure, good stability, easy control, and easy maintenance, so they are widely used in our production and life. However, with the large-scale use, its shortcomings are increasingly manifested. Vapor compression refrigeration systems basically use high-grade heat sources for energy. As the base increases, the load on our energy system is very large, and the waste heat generated in the p...
