Embodiment Construction
[0025] figure 2 Shown is a kind of application example diagram of the lithium bromide absorption heat pump unit with refrigerant water subcooling heat exchanger involved in the present invention on the single-effect unit, the unit consists of generator 1, condenser 2, absorber 3. Evaporator 4, heat exchanger 5, solution pump 6, refrigerant pump 7, refrigerant water subcooling heat exchanger 8, control system (not shown in the figure) and pipelines and valves connecting various components, etc. . The waste heat source flows through the evaporator 4, and the heat medium water flows through the absorber 3 and the condenser 2 in series. When the unit is running, the refrigerant water sprayed from the top of the evaporator 4 by the refrigerant pump 7 absorbs the heat of the waste heat source flowing through the heat transfer tube of the evaporator 4, enters the absorber 3 after being vaporized, and is absorbed by the concentrated lithium bromide solution therein. Release heat to...

The invention relates to a lithium bromide absorption heat pump set with a refrigerant water supercooling heat exchanger. The lithium bromide absorption heat pump set with the refrigerant water supercooling heat exchanger comprises a generator (1), a condenser (2), an absorber (3), an evaporator (4) and a heat exchanger (5), wherein the refrigerant water supercooling heat exchanger (8) is arranged in a refrigerant water pipeline system between the condenser (2) and the evaporator (4) of the set; and refrigerant water passes through the refrigerant water supercooling heat exchanger (8) and exchanges heat with other heat exchanging fluid flowing through the refrigerant water supercooling heat exchanger (8). The refrigerant water passes through the refrigerant water supercooling heat exchanger and exchanges heat with other heat exchanging fluid flowing through the refrigerant water supercooling heat exchanger, so that the temperature of the refrigerant water is reduced; under the conditions that the size of the set, the circulating amount of the refrigerant water and the consumption of a high-temperature heat source are unchanged, heat extracted from an afterheat source is increased,so that the heat generating capacity of the set is increased and the coefficient of performance (COP) of the set is improved; after obtaining heat, the heat exchanging fluid flows out of the refrigerant water supercooling heat exchanger; the heat exchanging fluid can be applicable to proper heat utilizing places as required.
Description
technical field [0001] The invention relates to a first-type lithium bromide absorption heat pump unit. It belongs to the technical field of air conditioning equipment. Background technique [0002] The first type of lithium bromide absorption heat pump unit such as figure 1 As shown, it consists of generator 1, condenser 2, absorber 3, evaporator 4, heat exchanger 5, solution pump 6, refrigerant pump 7, control system (not shown in the figure) and pipelines connecting various components , composed of valves. The waste heat source flows through the evaporator 4, and the heat medium water flows through the absorber 3 and the condenser 2. When the unit is running, the refrigerant water sprayed from the top of the evaporator 4 by the refrigerant pump 7 absorbs the heat of the waste heat source flowing through the heat transfer tube of the evaporator 4, enters the absorber 3 after being vaporized, and is absorbed by the concentrated lithium bromide solution therein. And rele...
