Abstract

The invention discloses a high-efficiency ammonia-water absorption-type refrigeration device, which adopts an ejector to substitute the original dilute solution throttling device, adopts dilute solution from a solution heat exchanger as the work fluid of the ejector and adopts ammonia steam from an evaporator as the driving fluid; and the dilute solution and the ammonia steam are injected into an absorber after being mixed and pressurized inside the ejector. The ejector recycles the energy discharged during the depressurization process of the dilute solution to be used for improving the absorption pressure of the absorber, so under the condition that the cooling water temperature and the heat source temperature are equal to that of the conventional ammonia-water absorption refrigeration system, the refrigeration coefficient of the system is improved; and moreover, since the ammonia steam and the ammonia-water dilute solution are adequately mixed inside the ejector, the absorber is simplified to a simple cooler.

Description

Technical field:

[0001] The invention relates to an ammonia water absorption refrigerating system, in particular to an ammonia water absorption refrigerating system which utilizes dilute solution spraying, mixing, pressurization and absorption. Background technique:

[0002] The basic principle of conventional ammonia water absorption refrigeration system is as follows: figure 1 As shown, it mainly includes the following parts: condenser A, ammonia liquid throttling device B, evaporator C, dilute solution throttling device F, absorber E, generator H, solution heat exchanger G, solution circulation pump D and distribution Condenser I.

[0003] The ammonia liquid cooled by the cooling water A1 in the condenser A is throttled and depressurized by the ammonia liquid throttling device B, and then evaporated and refrigerated by the carrier refrigerant C1 in the evaporator C; the evaporated ammonia vapor is sent to the absorber E , the ammonia vapor is cooled by the cooling water...
