Description

A kind of cold dual effect type lithium bromide jet suction type cooling cycle system

Technical field

The present invention relates to a kind of absorption type refrigeration circulating system, be specifically related to a kind of cold dual effect type lithium bromide jet suction type cooling cycle system.

Background technology

Traditional absorption type refrigeration circulating system as shown in figure 12, is formed primarily of generator 1, condenser 2, evaporimeter 3, second absorber 5, solution heat exchanger 6, first solution pump 10 and connected pipeline.Generator 1 is under the effect of external heat source, water as refrigerant steam lithium-bromide solution wherein being concentrated rear generation HTHP enters condensation in condenser 2 by the first water as refrigerant vapor line 11, the water as refrigerant that the temperature produced after condensation is lower enters in evaporimeter 3 via after first throttle expansion gear 8 reducing pressure by regulating flow by the first water as refrigerant path 12, in evaporimeter 3, become steam after the heat of water as refrigerant absorption refrigerating water backwater, by the second water as refrigerant vapor line 15 to input in the second absorber 5 absorb by lithium-bromide solution.In the second absorber 5, the lithium-bromide solution concentration absorbing steam reduces, done work by the first solution pump 10, by in the first weak solution pipeline 18 input generator 1, concentrating regenerative is carried out in generator 1, the concentrated solution produced after concentrated is returned in the second absorber 5 by the first concentrated solution pipeline 19 and continues to absorb steam, and wherein, the lithium-bromide solution in the first concentrated solution pipeline 19 and the first weak solution pipeline 18 carries out heat exchange by solution heat exchanger 6.

In above-mentioned Lithium Bromide Absorption Refrigeration Cycle system, due to the impact by solution self-characteristic, when temperature one timing of the first high-order thermal source 25 and low level heat energy 27, there is a upper limit in the absorption pressure of the second absorber 5 of system, thus causes the saturated weak solution outlet temperature of the second absorber 5 to there is a upper limit.Because the temperature of the first cooling thermal source 26 must lower than the saturated weak solution outlet temperature of the second absorber 5, therefore meet cooling require first cooling thermal source 26 temperature also there is a upper limit, if physical condition can provide first cooling thermal source 26 temperature higher than this upper limit, so above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system cannot normally work.Such as, when above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system being used for the heating condition of heat pump, if when heating water's return water temperature cools the temperature upper limit of thermal source 26 higher than above-mentioned first, then above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system just cannot realize; When above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system is used for the cooling condition of handpiece Water Chilling Units, if when the cold in-water temperature that can provide cools the temperature upper limit of thermal source 26 higher than above-mentioned first, then above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system also cannot realize.Therefore, the saturated weak solution outlet temperature of the absorption pressure and the second absorber 5 that improve the second absorber 5 just can improve the temperature upper limit of the first cooling thermal source 26, makes Lithium Bromide Absorption Refrigeration Cycle system meet application conditions and the field of higher first heat of cooling source temperature.

Because the second cooling thermal source 45 temperature must lower than condensation temperature, also there is a upper limit in the temperature therefore meeting the second cooling thermal source 45 that cooling requires, if the temperature of the second cooling thermal source 45 that physical condition can provide is higher than this upper limit, so above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system cannot normally work.Such as, when above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system being used for the heating condition of heat pump, when heat supply heat medium temperature to ask cools the temperature upper limit of thermal source 45 higher than above-mentioned second, then above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system just cannot realize; When above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system is used for the cooling condition of handpiece Water Chilling Units, if when the temperature of the cooling water that can provide cools the temperature upper limit of thermal source 45 higher than above-mentioned second, then above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system also cannot realize.Therefore, raising condensing pressure and condensation temperature just can improve the temperature upper limit of the second cooling thermal source 45, make Lithium Bromide Absorption Refrigeration Cycle system adapt to application conditions and the field of higher second heat of cooling source temperature.
