Abstract

The invention discloses an auxiliary vapor compression refrigeration system for semiconductor refrigeration driven by solar photovoltaic power generation. The auxiliary vapor compression refrigeration system comprises a common vapor compression refrigeration system body and a photovoltaic power generation driving semiconductor refrigeration system body which are coupled through a liquid accumulator; the photovoltaic power generation driving semiconductor refrigeration system body comprises a photovoltaic conversion device, the photovoltaic conversion device converts solar energy into electric energy, and the electric energy is output to serve as a direct current power source of a semiconductor refrigeration element; one end of the semiconductor refrigeration element is a cold end, the other end of the semiconductor refrigeration element is a hot end, and the cold end conducts heat exchange with intermediate medium water in the liquid accumulator; and the water in the liquid accumulator and refrigerants at an outlet of a condenser in the common vapor compression refrigeration system body are subjected to head exchange in a tube-shell type heat exchanger, the water passes through the shell pass, and the refrigerants pass through the tube pass, so that the refrigerants reach a supercooled state. According to the auxiliary vapor compression refrigeration system, the refrigerating capacity of the system is increased so that the purposes of improving the system energy efficiency ratio and reducing system energy consumption can be achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an auxiliary vapor compression refrigeration system driven by solar photovoltaic power generation for semiconductor refrigeration. Background technique [0002] In today's society, fossil fuels are facing depletion and the energy crisis is becoming more and more serious.
