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 mainly made up of generator 1, condenser 2, evaporimeter 3, the second absorber 5, solution heat exchanger 6, the first solution pump 10 and connected pipeline.Generator 1 is under the effect of external heat source, the water as refrigerant steam that produces HTHP after lithium-bromide solution wherein is concentrated enters condensation in condenser 2 by the first water as refrigerant vapor line 11, the lower water as refrigerant of the temperature that produces after condensation enters in evaporimeter 3 by the first water as refrigerant path 12 after via first throttle expansion gear 8 reducing pressure by regulating flows, in evaporimeter 3, after the heat of water as refrigerant absorption refrigerating water backwater, become steam, input in the second absorber 5 and absorbed by lithium-bromide solution by the second water as refrigerant vapor line 15.In the second absorber 5, the lithium-bromide solution concentration that has absorbed steam reduces, done work by the first solution pump 10, in the first weak solution pipeline 18 input generators 1, in generator 1, concentrate regeneration, the concentrated solution producing after concentrated is returned in the second absorber 5 and is continued to absorb steam by the first concentrated solution pipeline 19, 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, owing to being subject to the impact of 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, thereby causes the saturated weak solution outlet temperature of the second absorber 5 to have a upper limit.Because the temperature of the first cooling thermal source 26 must be lower than the saturated weak solution outlet temperature of the second absorber 5, therefore meet cooling requirement the first cooling thermal source 26 temperature also there is a upper limit, if the first cooling thermal source 26 that physical condition can provide temperature higher than this upper limit, so above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system cannot normally be worked.For example, while above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system being used for to the heating condition of heat pump, if heat supply hot water backwater temperature is during higher than the temperature upper limit of above-mentioned the first cooling thermal source 26, 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 to the cooling condition of handpiece Water Chilling Units, if the cold in-water temperature that can provide is during higher than the temperature upper limit of above-mentioned the first cooling thermal source 26, above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system also cannot realize.Therefore, improve the temperature upper limit that the absorption pressure of the second absorber 5 and the saturated weak solution outlet temperature of the second absorber 5 just can improve the first cooling thermal source 26, make Lithium Bromide Absorption Refrigeration Cycle system meet application conditions and the field of higher the first heat of cooling source temperature.
Because the second cooling thermal source 45 temperature must be lower than condensation temperature, also there is a upper limit in the temperature that therefore meets the second cooling thermal source 45 of cooling requirement, 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 be worked.For example, while above-mentioned traditional Lithium Bromide Absorption Refrigeration Cycle system being used for to the heating condition of heat pump, if the heat supply heat medium temperature requiring is during higher than the temperature upper limit of above-mentioned the second cooling thermal source 45, 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 to the cooling condition of handpiece Water Chilling Units, if the temperature of the cooling water that can provide is during higher than the temperature upper limit of above-mentioned the second cooling thermal source 45, 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 the second heat of cooling source temperature.
