Problems solved by technology
[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a waste heat-driven adsorption refrigeration unit. The heating and cooling of the adsorption bed are respectively completed through closed-circuit circulation, so as to solve the problem of flue gas corrosion caused by the alternation of cold and heat in the existing tradition. At the same time, reduce the number of valves to improve the reliability of the system operation, and change the working state of the valves in the system so that the valves are always in a positive pressure state to improve the working life of the system. At the same time, change the position of the return valve to make the adsorption Refrigeration units for true continuous cooling

Description
technical field [0001] The invention relates to a refrigerating unit in the technical field of refrigeration, in particular to a waste heat-driven adsorption refrigerating unit. Background technique [0002] Adsorption refrigeration has the advantages of zero ODP (ozone depletion potential), zero GWP (global warming potential), and the ability to utilize low-grade heat energy. It is in line with the human development theme of economic, environmental and sustainable development in the 21st century. The adsorption refrigeration system can use low-grade thermal energy, such as solar energy, industrial waste heat, engine waste heat and geothermal heat, which is of great significance to energy saving in the field of refrigeration / air conditioning, so it can alleviate the current tight supply of electricity. In addition, compared with vapor compression refrigeration, it has the characteristics of simple structure, no moving parts, low noise, and long life. Compared with absorption...
