Abstract
The utility model relates to a dual-purpose first class lithium bromide absorptive heat pump. A second condenser 2 is additionally installed in the same cavity of an evaporator 1 and communicated with an output heat source pipeline in parallel, a valve 11 is additionally arranged on the parallel pipeline. When water with high temperature is prepared, a heat source is driven to work for preparing a heat source with higher temperature than that of a waste heat source. When an available heat source with lower temperature than that of the waste heat source is prepared, the original heat pump can be used, and heat of the waste heat source can be used for heating the available heat source. Only exchanging a plurality of valves is needed, and other kinds of heat exchange equipment does not need to be additionally arranged. The utility model greatly reduces cost of investment for users and has the advantages of convenient installation and use.
Description
(1) technical field: the utility model relates to a kind of lithium bromide absorption type heat pump, and relating in particular to a kind of spent hot water can not directly use, and need exchange the heat pump that is lower than spent hot water's temperature thermal source for.
(2) background technology: first kind absorption heat pump is to reclaim the heat in wasted energy source with heat energy as drive energy, works under high vacuum state, and obtains the heating equipments that are higher than the waste heat source heat more.Because it effectively utilizes waste heat source, in use its thermal efficiency is more than 1.6.Because it must drive with high temperature heat source in using, during than the low available heat sources of waste heat source temperature, this heat pump can't meet the demands, and need set up heat transmission equipment and carry out heat exchange and obtain available heat sources in the needs use.Such method need increase very big investment, and the hot water tube system complexity.
(3) summary of the invention: the purpose of this utility model is to provide a kind of dual-purpose type first kind lithium bromide absorption type heat pump, not needing to set up under the prerequisite of heat transmission equipment, both can produce the thermal source that is higher than the waste heat source temperature, can produce the thermal source that is lower than the waste heat source temperature again.
The technical solution adopted in the utility model is: set up one second condenser in the same cavity of evaporimeter, heat outputting source capsule road is communicated with this second condenser is in parallel, and increases valve on this parallel pipeline.When need are produced than the high thermal source of waste heat source temperature, this valve closing.Heat pump is by former design condition work.Slightly during the available heat sources of low temperature, can not use driving heat source producing than waste heat source temperature.Open the valve of output thermal source, the spent hot water enters evaporimeter, starts cryogenic fluid pump, and the refrigerant vapour that its evaporator evaporation produces removes to heat the fluid of setting up in the condenser tube, and obtains available heat sources.
Because the utility model provides a kind of dual-purpose type heat pump, it with driving heat source work, produces the thermal source that is higher than the waste heat source temperature when producing high-temperature-hot-water.When need are produced than the low available heat sources of waste heat source temperature, can use former heat pump, use the heat heating available heat sources of waste heat source, only need to switch several valves, need not set up other heat transmission equipment, greatly reduce user's cost of investment, and easy to install.

Fig. 1 is the structure schematic flow sheet of former first kind lithium bromide absorption type heat pump.
The dual-purpose type first kind lithium bromide absorption type heat pump structure schematic flow sheet that Fig. 2 proposes for this patent.
(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, second condenser 2, cryogenic fluid pump 3, weak solution pump 4, absorber 5, concentrated solution pump 6, heat exchanger 7, generator 8, first condenser 9, throttling arrangement 10.This heat pump is compared with the heat pump of Fig. 1, sets up one second condenser 2 in the same cavity of former evaporimeter 1, and heat outputting source capsule road and these 2 in parallel connections of second condenser increase valve 11 on this parallel pipeline.It is when producing the output thermal source that is higher than the waste heat source temperature, with driving heat source work.When needs are produced than the lower slightly available heat sources of waste heat source temperature, can not use driving heat source.Open output thermal source valve, the spent hot water enters evaporimeter 1, starts cryogenic fluid pump 3, and the refrigerant vapour that its evaporator evaporation produces removes to heat the fluid of setting up in second condenser, 2 pipes, and obtains available heat sources.
