Problems solved by technology

But this kind of diffuse absorption refrigeration system has such disadvantages: since the solution lifting pump does not need external power, it relies on the thermosiphon phenomenon to drive the solution circulation, so the delivery volume of the solution is very limited, and the original absorber and evaporator Its structure is in the form of pipelines, and the area cannot be made larger, so that the cooling capacity of the entire system is very limited. The existing devices generally have a cooling capacity below 200W, which is only suitable for small refrigerators, thus limiting the use of this refrigeration technology. scope

Abstract

The present invention relates to diffusion and absorption refrigerator, belongs to the field of diffusion and absorption refrigerating technology, and aims at raising the refrigerating amount of diffusion and absorption refrigerator to realize relatively large diffusion and absorption refrigerating system. The diffusion and absorption refrigerator is provided with solution circulating pump between the solution recovering unit and the absorbing unit, liquid ammonia circulating pump between the evaporator and refrigerating terminal, evaporator with stuffing, absorbing liquid circulating loop, liquid ammonia circulating loop and ammonia-hydrogen mixture gas circulating loop. By means of the small power solution circulating pump and liquid ammonia circulating pump and great power absorber and evaporator, great refrigerating amount may be obtained. The present invention is suitable for various kinds of diffusion and absorption refrigerating system.

Description

technical field [0001] The invention relates to the technical field of diffusion absorption refrigeration. In particular, it is a diffusion absorption refrigeration device with a solution circulation pump and a liquid ammonia circulation pump. Background technique [0002] Diffusion absorption refrigeration system is a technology that utilizes thermal energy to refrigerate. It can use various waste heat as power, and the refrigerant is a typical environmentally friendly refrigerant. Therefore, the application of this technology is of great significance for improving environmental protection and energy utilization. The diffusion absorption refrigeration cycle consists of a refrigerant pair, an absorbent and a diffusant. An existing diffusion absorption refrigeration system uses ammonia as the refrigerant, water as the absorbent, and hydrogen as the diffusion agent, and consists of a generator, a condenser, an absorber, an evaporator, a regenerator and a solution lift pump. ...
