Water cooling type single pressure absorption refrigerator

Abstract

The present invention is a kind of single pressure absorbing refrigerator and relates to refrigerating equipment technology. The single pressure absorbing refrigerator includes a generator, a cooling water sleeve, a rectifier, an evaporator, a pre-cooler, a combined condensator / absorber, a liquid storage, a solution heat exchanger and a bubble pump. It has three loops, including one refrigerant loop between the evaporator and the condensator / absorber; one pressure poiser loop among the generator, the evaporator and the condensator / absorber; and one absorbent loop among the generator, the liquid storage and the condensator / absorber. The present invention has the advantages of silencing operation under single pressure, utilization of solar energy and waste heat, no power consumption, capacity of forming small household air conditioner, etc.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a technology of a small absorption refrigerating machine operating under a single system pressure. Background technique [0002] Under the circumstances that people's demand for comfortable air conditioners continues to increase, and the refrigeration and air conditioning industry is making unremitting efforts to reduce the impact of HCFC refrigerants on the environment, absorption refrigeration technology has a broad application space. The lithium bromide absorption refrigerator widely used at present adopts a dual-pressure cycle. The high and low pressure ends of the system need solution pumps and throttling devices to realize and maintain them. The system is complicated and inevitably generates noise and consumes electricity. At hundreds of kilowatts, it is concentrated in large-scale construction applications, and there are few small-scale systems suitable for...

Problems solved by technology

The lithium bromide absorption refrigerator widely used at present adopts a dual-pressure cycle. The high and low pressure ends of the system need solution pumps and throttling devices to realize and maintain them. The system is complicated and inevitably generates noise and consumes electricity. At hundreds of kilowatts, it is concentrated in large-scale construction applications, and there are few small-scale systems suitable for household applications; while the traditional small diffusion-absorption refrigerators that use ammonia-water-hydrogen three-working fluid cycle operation are also under a single pressure However, the cooling capacity of existing devices of this type is below 200w, which is not enough to meet the requirements of room air conditioners, and can only be made into small absorption refrigerators

Moreover, the pipeline routing of the diffusion-absorption refrigerator is complicated, so the manufacturing process is very demanding, and it is very difficult to achieve mass production
