Description

technical field [0001] The present invention relates to a separate solar energy absorption refrigeration system, more specifically, to a separate lithium bromide absorption refrigeration / heating system that adopts heat pipe direct evaporation, adopts capillary plastic material as heat exchanger, and is driven by solar energy. The system form of solution dehumidification integration. Background technique [0002] Solar absorption refrigeration technology originated in the first half of the 20th century. As a combination of low power consumption, pollution-free and ozone-depleting renewable energy utilization technology and absorption refrigeration technology, the key technology of solar refrigeration and air conditioning has matured. . However, compared with the compression system, solar refrigeration and air-conditioning technology still has many areas to be improved, such as simplifying the structure, reducing costs, optimizing the system, miniaturization and diversificati...

Problems solved by technology

[0005] At the same time, the traditional solar absorption refrigeration uses a copper tube metal heat exchanger, resulting in a large equipment volume. The lithium bromide solution used as the working medium of the bromine refrigerator is an alkaline and strong corrosive medium, so the heat exchange surface of each component is easily corroded by the solution and The cooling capacity decay and other problems caused by this

Therefore, in order to solve these problems, Chinese and foreign scholars have carried out a lot of research, such as adding corrosion inhibitors to lithium bromide solution, and using fluoroplastics as nano-scale coatings on the metal tube walls of heat exchangers, although these methods have achieved certain results. results, but the overall performance is not satisfactory
