Solar refrigeration system

Abstract

The invention discloses a solar refrigeration system, which comprises a tank body for storing a heat-conducting medium, a drainage pipe connected with an opening of the tank body, and a return pipe connected with a return port of the tank body. The drainage pipe is connected with the return pipe through a plurality of groups of distribution branch pipes; the plurality of groups of distribution branch pipes are inserted into a solar island; the solar island consists of a plurality of solar reflecting devices; and at least two solar reflecting devices are inserted into each group of distribution branch pipes. The solar refrigeration system also comprises a heat exchange device, wherein the return pipe passes through the heat exchange device; an inlet of the heat exchange device is connected with a water tank through a water inlet pipe; an outlet of the heat exchange device is connected with a single-screw expander through a pipeline; and an air outlet of the single-screw expander is connected with an air conditioner through the pipeline. Due to heat exchange of the heat exchange device, the single-screw expander is pushed to work for refrigeration, and the solar refrigeration system has the advantages that: the solar energy utilization efficiency is high, and the solar energy can be converted into power.

Description

technical field [0001] The present invention relates to a refrigeration device, more specifically to a solar refrigeration system that converts the sun into power to drive a single-screw expander for refrigeration. technical background [0002] Traditional refrigeration equipment uses a power supply to drive the compressor to work for refrigeration. It uses secondary energy as power and cannot directly use solar energy. Electricity is mainly converted from coal, oil or natural gas through power generation, while coal, oil, and natural gas These energy sources will not only be exhausted, but also cause environmental pollution. As a clean energy source, solar energy has broad development prospects. Devices related to utilizing the sun emerge in an endless stream, such as solar water heaters, etc., which have entered people's lives. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art, and provide ...
