Abstract

The invention relates to a solar cooling system in the technical field of solar utilization. According to the solar cooling system, high-pressure gas generated in a solar thermal collector enters a jet pump from a power fluid inlet of the jet pump, so that low-pressure gas in a thermal absorber is sucked into the jet pump. Gas pressure in the heat absorber is lowered so that liquid in the heat absorber can be evaporated, heat can be absorbed and cooling can be carried out. The solar cooling system can utilize low-focus-degree or non-focus low-grade solar energy to carry out cooling, and therefore the application of the solar energy is enriched.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar refrigeration system. Background technique [0002] The application of solar power generation or heating is very extensive, but due to the low grade of solar energy, especially low-focus or non-focused solar energy, if a device that utilizes this low-grade solar energy for refrigeration can be invented, the utilization rate of solar energy will be greatly improved. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Option 1. Solar refrigeration system, including solar heat collector, jet pump, heat exhauster and heat absorber, the pressure bearing capacity of the heated fluid channel of the solar heat collector is greater than 0.15MPa, and the heated fluid channel is set as a fluid A vaporization channel, the gas outlet of the fluid vaporization channe...
