(5) specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is former first kind lithium bromide absorption type heat pump structure flow chart.This heat pump is made up of generator 7, condenser 8, evaporimeter 1, absorber 4, solution heat exchanger 6, concentrated solution pump 5, weak solution pump 3, throttling arrangement 9, cryogenic fluid pump 2 and system pipeline, valve etc.Generator 7 and condenser 8 are arranged in the same cavity.Evaporimeter 1 and absorber 4 are arranged in the same cavity.Heat pump moves under high vacuum state during work, solution pump 5 is carried the bromize lithium dilute solution of absorber, after heating up, heat exchanger 6 enters generator 7, driving heat source adds the weak solution in the heater 7, make its boiling produce refrigerant vapour, refrigerant vapour enters condenser 8, is condensed into water as refrigerant by the output thermal source hot water that flows in managing, and output thermal source temperature in condenser 8 raises.Water as refrigerant in the condenser 8 enters evaporimeter 1 after throttling, in evaporimeter 1 copper pipe surface, because heat pump is a high vacuum, the heat of vaporization that water as refrigerant is drawn the waste heat source that flows in evaporimeter 1 pipe becomes refrigerant vapour by the cryogenic fluid pump delivery profile.This refrigerant vapour enters absorber 4 and is absorbed in absorber 4 by the concentrated solution from generator 7, and the absorption latent heat that absorption process produces adds output thermal source in heat absorber 4 pipes, and the heat outputting source temperature is raise.In the course of work of heat pump, the heat part of driving heat source flows to the output thermal source of condenser; Another part has entered absorber, and the conversion of the heat of evaporimeter waste heat source enters the output thermal source that a part of thermal source that absorber and generator come adds heat absorber together.The input thermal source of heat pump is the thermal source of driving heat source and waste heat source.This two part of heat energy enters from generator and evaporimeter, and the output thermal source obtains from condenser and absorber.In the course of work of heat pump, the output thermal source has been given in driving heat source 100% conversion, adds the recovery heat of evaporimeter waste heat source under the high vacuum state, so quantity of heat given up is much higher than the heat of driving heat source, has played the effect in effectively reclaiming waste heat source.
Each functions of components is at work: generator is in the process of heat conversion and concentrate lithium-bromide solution, and condenser obtains water as refrigerant finishing under the prerequisite that is converted to the generator heat.The water as refrigerant that evaporimeter utilizes generator, condenser to provide comes the waste heat source heat in the suction pipe, makes water as refrigerant become refrigerant vapour.Absorber utilizes the concentrated solution of generator to absorb the refrigerant vapour heating output thermal source of evaporimeter.Solution heat exchanger reclaims the heat of concentrated solution and improves the thermal efficiency.
The dual-purpose type first kind lithium bromide absorption type heat pump structure schematic flow sheet that Fig. 2 proposes for this patent.Among the figure: evaporimeter 1, cryogenic fluid pump 2, water as refrigerant liquid capsule 3, weak solution liquid capsule 4, weak solution pump 5, weak solution switch valve 6, weak solution pipe 7, weak solution liquid dish 8, absorber 9, concentrated solution dish 10, concentrated solution switch valve 11, solution heat exchanger 12, concentrated solution pump 13, generator 14, condenser 15, water as refrigerant arm 16, water as refrigerant arm switch valve 17, throttling arrangement 18, U type pipe 19, cryogen water pipe 20, water as refrigerant switch valve 21.
This heat pump is compared with the heat pump of Fig. 1, set up solution dish 8 in absorber 9 bottoms, between the liquid capsule 4 of solution dish 8 and absorber 9 bottom solution weak solution pipeline 7 being set is communicated with, and on this pipeline 7, valve 6 is set, between the water as refrigerant liquid capsule 3 of solution dish 8 and evaporimeter 1 pipeline 20 being set is communicated with, and on this pipeline 20, valve 21 is set, leading at condenser 15 increases arm 16 towards absorber 9 on the water as refrigerant pipeline 19 of evaporimeter 1, and increases valve 17 on this pipeline 16.Go out on the pipeline that heat exchanger 12 enters absorber 9 to set up arm 10 in concentrated solution, directly lead to absorber 9 bottom weak solution liquid capsules, and on this pipeline 10, valve 11 is set.Its when producing than the high output thermal source of waste heat source temperature, driving heat source work.When producing than the low output thermal source of waste heat source temperature, as long as start cryogenic fluid pump 2, water as refrigerant is distributed to the tube-surface of evaporimeter 1, and water as refrigerant is drawn the waste heat source temperature and gasified and become refrigerant vapour.Output thermal source in this water vapour heating absorber tube, water vapour is condensed into water.This water as refrigerant flows into water as refrigerant liquid capsule 3 through weak solution liquid dish 8 and water as refrigerant liquid capsule 3 connecting pipes 20, has finished cyclic process like this.The effect of valve 21 is to state circulation time in realization to open, and allows the water as refrigerant of absorber 9 enter water as refrigerant liquid capsule 3.When this valve need be worked with driving heat source at heat pump, promptly close valve 21, open valve 6, the weak solution of weak solution dish 8 flows into weak solution capsules 4 by pipeline 7.Valve 6 is in close valve state when producing the output thermal source that is lower than the waste heat source temperature.Do not allow water as refrigerant enter weak solution liquid capsule.The effect of weak solution valve 11 and water as refrigerant transfer valve 17 simultaneously is: produce than waste heat source temperature slightly during the available heat sources of low temperature at needs, opening concentrated solution goes out heat exchanger and leads to the valve 11 on the pipeline of absorber bottom and open condenser and lead to valve 17 on the absorber pipeline, start the heat pump running, driving heat source adds the lithium-bromide solution in the heater, produce refrigerant vapour and directly add heat absorber and the interior available heat sources of condenser tube, the water as refrigerant that the absorber condensation produces is got back to absorber liquid capsule, such running purpose is that the solution at the absorber position water as refrigerant with condensation is washed away totally, guarantee in running, lithium-bromide solution in the original absorber is cleaned up, do not allow lithium-bromide solution enter absorber again, obtain clean water as refrigerant when guaranteeing operation.The operation a few hours, record water as refrigerant pure after, promptly stop the heat pump for supply driving heat source.Close the valve 6 that liquid dish 8 leads on the weak solution liquid capsule pipeline, open the valve 21 that liquid dish 8 leads on water as refrigerant liquid capsule 3 pipelines.The spent hot water enters evaporimeter, starts cryogenic fluid pump 2, and the refrigerant vapour that its evaporator evaporation produces removes to heat the fluid in the absorber tube, and obtains available heat sources.
