Description
Technical field
The present invention relates to a kind of direct-burning lithium bromide absorption cold-hot water assembing group.Belong to air conditioner technical field.
Background technology
Direct combustion type dual effect type cold/hot water machine of lithium bromide group as shown in Figure 1, is made up of the pipeline of direct combustion high pressure generator 1, low pressure generator 9, condenser 8, evaporimeter 5, absorber 5, cryogenic fluid heat exchanger 3, high-temperature solution heat exchanger 2, heating solution transfer valve 12, heating refrigerant vapour transfer valve 13, solution pump 6, cryogenic fluid pump 7, valve, control system (not shown) and connecting components at present.When unit moves in heating operating mode, heating solution transfer valve 12 and heating refrigerant vapour transfer valve 13 are opened, cryogenic fluid pump and external system cooling water pump stop, the low-temperature water heating coming from air conditioner user enters in heat exchange pipe of evaporator, the heat of condensation of the water vapour being produced by heat exchange pipe external surface direct combustion high pressure generator heat dilute solution heats, temperature is sent to heating user after raising, the water as refrigerant that solution after direct combustion high pressure generator is concentrated enters in absorber and after condensing is mixed into weak solution, is again circulated and heats toward direct combustion high pressure generator from solution pumping.When heating water outlet reaches 60 ℃, solution temperature reaches 110 ℃ of left and right, 50 ℃ of left and right of heating hot water and the solution temperature difference.In the time that needs are produced more than 70 ℃ high temperature heating water, may exceed the resistance to extreme temperature of existing solution pump, operational reliability reduces greatly.Another direct combustion high pressure generator exhaust gas temperature rises, heating decrease in efficiency.Produce at present high temperature heating hot water and conventionally adopt flow process as shown in Figure 2, on traditional direct combustion high pressure generator, heating hot water heat exchanger 16 is set.In the time of heating operation, heating solution transfer valve and heating refrigerant vapour transfer valve to be closed, the independent similar boiler operatiopn of direct combustion high pressure generator, produces refrigerant vapour and enters heating hot water heat exchanger heating water, and the solidifying water of refrigerant vapour is got back to direct combustion high pressure generator.Which systematic comparison complexity, cost is high, while producing high temperature heating water, because solution temperature is higher, causes exhaust gas temperature higher, affects the heating thermal efficiency.How to find the novel direct-burning lithium bromide absorption cold-hot water assembing of producing high-temperature-hot-water that a kind of effective reduction solution running temperature, system are simple, heating efficiency is high to consist of one of important topic of current research.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the direct-burning lithium bromide absorption cold-hot water assembing group of producing high-temperature-hot-water that a kind of effective reduction solution running temperature, system are simple, heating efficiency is high is provided.
The object of the present invention is achieved like this: a kind of direct-burning lithium bromide absorption cold-hot water assembing group of producing high-temperature-hot-water, comprise direct combustion high pressure generator, low pressure generator, condenser, evaporimeter, absorber, cryogenic fluid heat exchanger, high-temperature solution heat exchanger, solution pump and cryogenic fluid pump, between solution pump discharge pipeline and evaporimeter water as refrigerant liquid capsule, set up a solution communicating pipe, solution transfer valve was set on solution communicating pipe.
In the time that heating operating mode is moved, solution transfer valve is opened, solution pump discharge solution is divided into two tunnels, it is concentrated that one tunnel enters high pressure generator heating, separately leads up to and enter evaporimeter liquid capsule solution communicating pipe, makes the liquid in evaporimeter liquid capsule become weak solution from original water as refrigerant, open cryogenic fluid pump, weak solution in evaporimeter liquid capsule is evenly distributed to outside heat-transfer pipe of evaporator, and lithium-bromide solution is emitted the heat of condensation of refrigerant vapour, the hot water that heating is flowed through in heat-transfer pipe of evaporator in the time absorbing refrigerant vapour.
The invention has the beneficial effects as follows:
The present invention is by above-mentioned flow process, under heating operating mode, weak solution temperature is higher than in 10 ℃ of heating hot water outlet temperatures, reduce by 40 ℃ of left and right than traditional approach, while producing high-temperature-hot-water, solution temperature is effectively controlled, and has improved operational reliability, exhaust gas temperature reduces by 40 ℃ simultaneously, fuel consumption 2% left and right that declines, improves energy utilization rate, and has reduced the thermal pollution of smoke evacuation to environment.
