Technical field
The utility model relates to a kind of absorption heat pump unit that utilizes low-temperature heat source for the energy.This absorption heat pump unit is the heat pump assembly that adopts lithium bromide-water absorption type refrigeration principle design, mainly is made up of parts such as water at low temperature water inlet pipe, water at low temperature outlet pipe, heater, heater bromize lithium dilute solution efferent duct, bromize lithium dilute solution shower, generator, bromize lithium concentrated solution liquid trap, water vapour passage, absorber, bromize lithium concentrated solution shower, heat(ing) coil, heat(ing) coil hot water outlet pipe, heat(ing) coil hot water inlet pipe, bromize lithium dilute solution liquid trap, bromize lithium dilute solution efferent duct, bromize lithium dilute solution delivery pump, bromize lithium dilute solution carrier pipe, bromize lithium concentrated solution efferent duct, bromize lithium concentrated solution delivery pump, bromize lithium concentrated solution carrier pipes.In the existing lithium bromide-water absorption refrigerating plant, producing cold effect is evaporimeter, and producing fuel factor is condenser and absorber.When freezing summer, can in evaporimeter, extract water at low temperature confession idle call, reverse thinking also can be taken out the high-temperature-hot-water in the absorber in the winter time be used for winter heating.The imagination of absorption heat pump unit; Main purpose is the condensation heat of utilizing in lithium bromide-water refrigerating plant and absorption heat; Promote the temperature of water at low temperature; Can make the temperature of the temperature of output water, the temperature of low-temperature wastewater brought up to available high-temperature water, thereby can better utilize underground low temperature thermal source and factory's low-temperature wastewater greater than input water.Through the high-temperature water that absorption heat pump unit is made, can directly be used for the Process heat of heating system and factory.
Background technology
At present, existing heat pump is to adopt the compression-type refrigeration principle mostly, the air-cooled and water-cooled heat pump of the electrodynamic type that is designed to.Absorption heat pump is at present also rarely found, because the heat pump effect of absorption heat pump does not have the effect of compression heat pump obvious, so the heat pump of research employing lithium bromide-water refrigeration principle seldom.All refrigerating plants can both produce hot and cold effect, and lithium bromide-water absorption refrigerating plant is no exception, when doing heat pump work, all a large amount of low-temperature heat sources will be arranged, could operate as normal.The low-temperature wastewater of China factory and cryogenically descend heat mostly at 10～20 ℃ does not have value to be wasted because temperature is low mostly, uses a large amount of electric power again if adopt the electrodynamic type heat pump to promote temperature.Utilize lithium bromide-water absorption type heat pump to promote temperature, can utilize a large amount of low-temperature heat sources and a spot of electric power, 10～20 ℃ low-temperature heat are risen to about 50～70 ℃, reach the temperature requirement of heating and Process heat water.
Summary of the invention
The purpose of the utility model provides a kind of, utilizes lithium bromide-water absorption type refrigeration principle, the absorption heat pump unit of design.
The purpose of the utility model is to realize like this; Lithium bromide-water absorption refrigerating plant; Form by heat exchangers such as heater, generator, condenser, evaporimeter, absorbers; In process of refrigerastion, can produce,, often adopt a large amount of cooling waters that heat is discharged in order to reach the purpose of refrigeration above the used heat of heater.Absorption heat pump is a purpose to heat; In lithium bromide-water absorption refrigerating plant; Cancelled is condenser, the evaporimeter that order gets with the refrigeration; Having kept to heat is heater, generator and the absorber that order gets, and utilizes the absorption hot and cold in absorption and the condensation process to coagulate heat, with the temperature raising of water.Its course of work is: low-temperature water heating gets into the heater heating from the absorber, has accomplished the lithium bromide-water weak solution of absorption process.Heated lithium bromide-water weak solution is sent into generator by pipeline.Water in generator in the weak solution is separated, and produces water at low temperature steam and bromize lithium concentrated solution, and water at low temperature steam gets into absorber by the water vapour passage.Lithium bromide-water concentrated solution is pumped into the concentrated solution shower of absorber by concentrated solution; Bromize lithium concentrated solution is sprayed on the heat(ing) coil of absorber uniformly; Absorption is from the water at low temperature steam of generator; In absorption process, will produce a large amount of absorption heat, absorb the temperature raising of heat lithium-bromide solution.The absorption heat of lithium bromide-aqueous solution surpasses the heat that adds of heater, absorbs the hot water that is heated continuously in the coil pipe and takes away, and supplies the user to use.After the lithium bromide-aqueous solution that has absorbed a large amount of water vapours has been accomplished absorption process, convert lithium bromide-water weak solution to by lithium bromide-water concentrated solution.Lithium bromide-water weak solution is sent into heater by the bromize lithium dilute solution delivery pump through pipeline again, the defeated generator continuous process once more of sending into again of the bromize lithium dilute solution after being heated.
Owing to adopted such scheme,, be designed to absorption heat pump unit with regard to the heat of the absorption in the absorption type refrigerating unit capable of using.
