Flue gas and hot water single-double-effect combined type lithium bromide absorption water chilling unit

Abstract

The invention relates to a flue gas and hot water single-double-effect combined type lithium bromide absorption water chilling unit, and belongs to the technical field of air conditioning equipment. The flue gas and hot water single-double-effect combined type lithium bromide absorption water chilling unit comprises a hot water side generator (1), a flue gas side high pressure generator (2), a flue gas side low pressure generator (3), a condenser (4), a high temperature heat exchanger (5), a low temperature heat exchanger (6), a second solution pump (7), an absorber (8), a first solution pump (9), a coolant pump (10), an evaporator (11) and a flue gas solution heat exchanger (12). The hot water side generator (1) and the flue gas side low pressure generator (3) are arranged in a cavity, and a heat transfer pipe bundle is arranged up and down. The second solution pump (7) is arranged at a strong solution outlet of the flue gas side low pressure generator (3). The water chilling unit can fully utilize the hot water with the temperature being decreased to conduct refrigeration.
