Two-stage flue gas hot water lithium bromide absorption refrigeration unit with upper and lower sections

Abstract

The invention relates to a vertically-sectioned two-section type smoke hot water type lithium bromide absorption type refrigerating unit. The vertically-sectioned two-section type smoke hot water type lithium bromide absorption type refrigerating unit is characterized in that a low-pressure section evaporator (21), low-pressure section absorbers (19), a high-pressure section evaporator (1) and high-pressure section absorbers (2) are arranged in one evaporation absorber barrel (25), and a transversely-arranged evaporation and absorption sectioned partition plate (23) is arranged between the low-pressure section evaporator (21)and the high-pressure section evaporator (1) and between the low-pressure section absorbers (19) and the high-pressure section absorbers (2); and a steam generator (14), a high-pressure section condenser (13), a hot water generator (15) and a low-pressure section condenser (17) are arranged in one generation condenser barrel (45), and a generation condenser sectioned partition plate (44) is arranged among the steam generator (14), the high-pressure section condenser (13), the hot water generator (15) and the low-pressure section condenser (17). According to a solution heat exchanger, arranged components are few, and a solution circulation pipeline is simplified.

Description

technical field [0001] The invention relates to a lithium bromide absorption refrigerator. It belongs to the technical field of air conditioning equipment. Background technique [0002] A previous two-stage flue gas hot water lithium bromide absorption refrigeration unit such as figure 1 The shown two-stage flue gas hot water single-double-effect composite lithium bromide absorption chiller and hot water unit. The two-stage evaporative absorber of the unit adopts a left and right segmental structure, the evaporator includes a single-effect evaporator 32 and a double-effect evaporator 35, the absorber includes a single-effect absorber 31 and a double-effect absorber 34; the condenser includes a low-pressure section Condenser 17 (also known as single-effect condenser) and high-pressure section condenser 13 (also known as double-effect condenser), solution pump includes single-effect solution pump 33 and double-effect solution pump 34, solution heat exchanger includes single-...

AI Technical Summary

Problems solved by technology

However, this unit has the disadvantages that there are many components in the solution heat exchanger and the solution circulation pipeline is relatively complicated.
