Technical field
The utility model belongs to the heating equipment technical field, particularly a kind of high efficiency lithium bromide absorption type heat pump.
Background technology
The heat-exchange system of using lithium bromide absorption type heat pump in the heat supply secondary station can increase the heat transfer temperature difference of one-level heating network, is a kind of effective way that increases existing pipe network heat capacity, reduces the heat supply investment.The absorption heat pump heat-exchange system mainly is made up of warm water type lithium bromide absorption type heat pump and heat exchanger, because the lithium bromide absorption type heat pump heating efficiency is generally 1.6～1.8, the heat exchange of heat exchanger does not consider to lose efficient can think 1.0, and at present in this system absorption heat pump driving heat source heat, absorption heat pump recovery waste heat heat and heat exchanger heat exchange amount three ratio be 1.6:1.0:1.6, that is to say that the overall efficiency of this system is about 1.3 at present.If can allow absorption heat pump reclaim more heat so in this system, not only the overall efficiency of system can rise thereupon, also can further strengthen the first-level pipeline network heat supply temperature difference, thereby further increases existing heating network heat capacity.
The utility model content
For overcoming the above problems, the utility model provides a kind of high efficiency lithium bromide absorption type heat pump heat exchange unit, this unit is used in combination with heat exchanger, can further improve absorption heat pump recovery heat in the absorption heat pump heat exchange unit, thereby raising system effectiveness, increase the heating network temperature difference, increase existing heating network heat capacity.The technical scheme that the utility model adopts for achieving the above object is: a kind of high efficiency lithium bromide absorption type heat pump heat exchange unit, comprise lithium bromide absorption type heat pump, heat exchanger and connecting line, described lithium bromide absorption type heat pump comprises generator, condenser, absorber and evaporimeter, generator is connected with condenser, and absorber is connected with evaporimeter; It is characterized in that: have additional regenerator in the lithium bromide absorption type heat pump, wherein absorber, regenerator, generator are communicated with the circulation of formation lithium-bromide solution by pump and pipeline; Water as refrigerant in the condenser enters evaporimeter through throttling arrangement, and first-level pipeline network heat supply hot-water line passes generator, regenerator, heat exchanger and evaporimeter successively from the water inlet to the delivery port; Absorber and the condenser of heat exchanger and lithium bromide absorption type heat pump passed in the parallel connection of secondary network heat supply hot-water line or series connection.
Described lithium bromide absorption type heat pump and heat exchanger adopt integral structure, perhaps split-type structural.
The utility model increases regenerator machine connecting line on existing warm water type lithium bromide absorption type heat pump basis, utilize this regenerator can bromizate the lithium absorption heat pump and reclaim more heats in heat-exchange system, thereby improve heat-exchange system efficient.After the driving heat source of first-level pipeline network hot water as lithium bromide absorption type heat pump, the concentrated solution temperature of its temperature and lithium bromide absorption type heat pump is suitable, but still be higher than the weak solution temperature, the utility model is exactly to utilize the regenerator that increases to bromizate the weak solution and the further heat exchange of first-level pipeline network hot water of coming out from generator of lithium absorption heat pump, thereby strengthen first-level pipeline network hot water as the use amount of lithium bromide absorption type heat pump driving heat source part, because lithium bromide absorption type heat pump driving heat source heat is proportional with reclaiming the low temperature exhaust heat amount, so the low temperature exhaust heat heat that lithium bromide absorption type heat pump reclaims also can further strengthen, so just make that absorption heat pump reclaims more first-level pipeline network hot water heat in this heat-exchange system, and the heat that heat exchanger reclaims reduces, and realizes improving the efficient purpose of absorption heat pump heat-exchange system.The utility model improves the overall efficiency of lithium bromide absorption type heat pump heat-exchange system, adopts this technology that this system synthesis efficient is brought up to more than 1.4 from 1.3.Can a step increase the first-level pipeline network heat supply temperature difference, improve the first-level pipeline network heat capacity.

The specific embodiment
Describe the utility model in detail below in conjunction with embodiment and accompanying drawing, but the utility model is not limited to specific embodiment.
Embodiment
As shown in Figure 2, a kind of high efficiency lithium bromide absorption type heat pump heat exchange unit, comprise lithium bromide absorption type heat pump 1, heat exchanger 2 and connecting line, described lithium bromide absorption type heat pump comprises generator 1-1, condenser 1-2, absorber 1-3 and evaporimeter 1-4, regenerator 1-5, its inner annexation is that generator 1-1 is connected with condenser 1-2, and absorber 1-3 is connected with evaporimeter 1-4; Wherein absorber 1-3, regenerator 1-5, generator 1-1 are the lithium-bromide solution circulation, namely the bromize lithium dilute solution that comes out from absorber 1-3 is introduced into regenerator 1-5 by pump and pipeline and enters generator 1-1 then and become bromize lithium concentrated solution, returns absorber 1-3; Condenser 1-2, evaporimeter 1-4 are the circulation of cold-producing medium water, the water as refrigerant that comes out from condenser 1-2 enters evaporimeter 1-4 through throttling arrangement, and first-level pipeline network heat supply hot-water line 3 passes generator 1-1, regenerator 1-5, heat exchanger 2 and evaporimeter 1-4 successively from the water inlet to the delivery port; Absorber 1-3 and the condenser 1-2 of heat exchanger 2 and lithium bromide absorption type heat pump passed in 4 parallel connections of secondary network heat supply hot-water line.
This unit running process is: first-level pipeline network hot water 3 enters generator 1-1 realize heat exchange cooling as driving heat source after, enter regenerator 1-5 and lithium-bromide solution heat exchange and realize the secondary heat exchange cooling, enter heat exchanger 2 then and realize three heat exchange cooling with the heat exchange of secondary network hot water, enter evaporimeter 1-4 at last and carry out four heat exchange of waste heat recovery realization cooling back as the first-level pipeline network backwater; Secondary network backwater 4 can be connected also can in parallel enter absorber 1-3, condenser 1-2 and the heat exchanger 2 of lithium bromide absorption type heat pump, mixes the back then as secondary network heat supply hot water.This system is because increasing the heat that regenerator 1-5 reclaims, bromizating the lithium absorption heat pump utilizes more heat as driving heat source in this heat-exchange system, the low temperature exhaust heat of corresponding evaporimeter recovery is also more with it, the first-level pipeline network heat that absorption heat pump can be recycled in this system like this is more, heat exchanger reclaims heat to be reduced, because of lithium bromide absorption type heat pump efficient far above heat exchanger, therefore using this system can improve the system synthesis heat exchange efficiency, and the first-level pipeline network heat supply temperature difference is further strengthened.In the above system, lithium bromide absorption type heat pump and heat exchanger adopt split-type structural, also can adopt integral structure (omitting diagram).Secondary network hot water enters lithium bromide absorption type heat pump and the heat exchanger employing is connected in parallel, and also can be absorber and condenser (omitting diagram) that heat exchanger and lithium bromide absorption type heat pump are passed in the series connection of secondary network heat supply hot-water line.
