Abstract

The invention relates to a smoke lithium bromide absorption refrigerating unit with a smoke solution heat exchanger. The smoke lithium bromide absorption refrigerating unit comprises a high pressure generator, an evaporator (1), an absorber (2), a low pressure generator (12), a condenser (13), a high-temperature heat exchanger (5), and a low-temperature heat exchanger (4). A waste heat smoke outlet tube (8) of the high pressure generator is provided with a smoke solution heat exchanger (26). A dilute solution outgoing tube of the low-temperature heat exchanger (4), as a smoke solution heat exchanger solution incoming tube (24), is connected to the smoke solution heat exchanger (26); a smoke solution heat exchanger solution outgoing tube (25) is connected to the high-temperature heat exchanger (5). Emission temperature of waste heat smoke from the smoke lithium bromide absorption refrigerating unit can be further lowered both in refrigerating and heating.

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] Previous flue gas type lithium bromide absorption refrigeration units such as figure 1 and figure 2 The shown flue gas type lithium bromide absorption chiller. This unit uses the high-temperature waste heat flue gas discharged from an external device to heat the lithium bromide solution in the flue gas-type high-pressure generator 7 to drive refrigeration (heat) operation, and is mainly used in natural gas distributed energy supply systems and industrial kiln flue gas waste heat air conditioning systems. figure 2 The unit is equipped with a direct-fired high-voltage generator 21 (also known as a supplementary-fired high-pressure generator), the flue gas-type high-voltage generator and the direct-fired high-voltage generator are arranged in series, and there is a high-fired solution conne...
