Embodiment Construction

[0012] Such as figure 2 As shown, it consists of high pressure generator 1, low pressure generator 2, condenser 3, evaporator 4, absorber 5, low temperature solution heat exchanger 6, working steam condensate solution heat exchanger 7, high temperature solution heat exchanger 8, high A high-efficiency steam double-effect lithium bromide absorption chiller composed of refrigerant steam condensate heat exchanger 9, solution pump, refrigerant pump, control system (not shown in the figure) and pipelines and valves connecting various components The unit has added a high-refrigerant steam condensate heat exchanger 9,

[0013] The specific process is that the dilute solution in the absorber 5 is boosted by the solution pump and divided into two paths, one path enters the low-temperature solution heat exchanger 6 and the high-temperature solution heat exchanger 8 in series to raise the temperature, and the other path enters the high-refrigerant steam condensate water exchanger in ser...

Abstract

The invention relates to a high-efficiency steam double-effect lithium bromide absorption type water chilling unit comprising a high-pressure generator (1), a low-pressure generator (2), a condenser (3), an evaporator (4), an absorber (5), a low-temperature solution heat exchanger (6), a working steam-condensed water solution heat exchanger (7), a high-temperature solution heat exchanger (8), a solution pump and a chilling agent pump. The water chilling unit is additionally provided with a high-chilling agent steam-condensed water heat exchanger (9), dilute solutions in the absorber are divided into two paths through the solution pump, one path is connected in series and sequentially enters the low-temperature solution heat exchanger (6) and the high-temperature solution heat exchanger (8), the other path is connected in series and sequentially enters the high-chilling agent steam-condensed water heat exchanger (9) and the working steam-condensed water solution heat exchanger (7) for raising temperature, the two paths of temperature-raised dilute solutions independently or together enter the high-pressure generator (1) and the low-pressure generator (2), and a chilling agent enters the condenser (3) after entering the high-chilling agent steam-condensed water heat exchanger (9). Through the optimization of solution processes, the consumption of working steam can be reduced by about 5%, and meanwhile, the invention reduces the load of the condenser and the consumption of chilling water amount.

Description

(1) Technical field [0001] The invention relates to a steam double-effect lithium bromide absorption chiller. It belongs to the technical field of air conditioning equipment. (2) Background technology [0002] At present, the solution series process steam double-effect lithium bromide absorption refrigeration unit such as figure 1 , consisting of high-pressure generator 1, low-pressure generator 2, condenser 3, evaporator 4, absorber 5, high-temperature solution heat exchanger 8, low-temperature solution heat exchanger 6, working steam condensate solution heat exchanger 7, solution pump, It consists of a refrigerant pump, a control system (not shown in the figure), pipelines and valves connecting various components. The dilute solution of the absorber is boosted by the solution pump and enters the low-temperature solution heat exchanger 6 , the working steam condensate solution heat exchanger 7 and the high-temperature solution heat exchanger 8 sequentially in series. Sin...
