Double chamber vortex generator for single effect solar energy absorption refrigeration system

Abstract

The invention relates to a double-chamber vortex generator used in a single-effect solar absorption refrigeration system, belonging to the refrigeration technical field. The double-chamber vortex generator comprises a low pressure generating chamber and a high pressure generating chamber. After fluid is heated to a certain temperature by an external heat source, the fluid enters the generator through a nozzle which is in tangency with the low pressure generating chamber to generate rotational flow motion, so as to effectively reduce the evaporation pressure and the evaporation temperature of solution in the generator, improve utilizable temperature difference of the heat source and increase condensing vapor used for refrigeration cycle. The double-chamber vortex generator has the advantages that: the double-chamber vortex generator has a simple structure, no moving element, low cost, high efficiency, energy conservation and environmental protection, and can effectively utilize low-level energy source (such as solar energy, geothermal energy and tide energy) as drive heat source of the generator.

Description

technical field [0001] The invention relates to a double-chamber vortex generator used in a single-effect solar absorption refrigeration system, which belongs to the technical field of refrigeration. Background technique [0002] Absorption refrigeration has made a breakthrough in the field of solar energy utilization in recent years because of its ability to utilize low-temperature heat sources. Solar air conditioners are air conditioners that use solar energy as the cooling energy. There are two ways to use solar energy for cooling. One is to use photovoltaic technology to generate electricity and use electricity to drive conventional compression refrigerators for cooling; the other is to perform light-to-heat conversion and use heat as Energy refrigeration. The former system is relatively simple, but based on the current cost price of photoelectric conversion, its cost is 3-4 times that of the latter; the latter can also be used in combination with heating in addition to...
