Description
Technical field
The utility model relates to a kind of air-conditioning system, particularly relates to a kind of air-conditioning system of lithium bromide absorption cooling and warming water machine.
Background technology
Along with the raising of people's quality of life, except there being the demand of air conditioner cold-warm, increasing user also has the demand of continual use health hot water.In order to adapt to the variation of this market demand, the producer of more and more freezing is devoted to the lithium-bromide absorption-type refrigerating machine that exploitation provides health hot water.Common way on market is on lithium bromide absorption cooling and warming water machine basis, to append health hot water heat exchanger now, usually health hot water heat exchanger is arranged on high-temperature generator, the solidifying water of cryogen in health hot water heat exchanger has returns to high-temperature generator, and entering in kind of refrigeration cycle of having gone; Cooling condition and heating operating mode realize by changes in temperature transfer valve is set.
As shown in Figure 1, existing lithium bromide absorption cooling and warming water machine group in the fall, when winter and spring, for warm water is produced separately operation mode, be high-temperature generator independent operation pattern: first valve-off (solution inlet port transfer valve) F1, valve (taphole transfer valve) F2, valve (refrigerant vapour outlet transfer valve) F3, open valve (air-conditioning heating water heat exchanger cryogen Condensate Controlling Equipment valve) F5, valve (cryogen Condensate Controlling Equipment valve for health hot water) F6.Burn in the burner solution of 1 li of the heat heating high-temperature generator that produces of combustion gas or fuel oil, make the cryogen in solution absorb heat vaporization out, refrigerant vapour enters the health hot water heat exchanger 15 on high-temperature generator top by refrigerant vapour pipeline 17, because be added with health hot water in the heat-transfer pipe of health hot water heat exchanger 15, so health hot water absorbs the latent heat of refrigerant vapour, be heated, and the refrigerant vapour that has been absorbed latent heat becomes the solidifying water of cryogen and uses cryogen Condensate Controlling Equipment valve F6 and health hot water to get back to high-temperature generator 1 with cryogen condensate line 18 by health hot water.Another part refrigerant vapour that high-temperature generator 1 produces is also by refrigerant vapour pipeline 17, to enter the air-conditioning heating water heat exchanger 16 on high-temperature generator 1 top, because have air-conditioning heating water in the heat-transfer pipe of air-conditioning heating water heat exchanger 16, so air-conditioning heating water absorbs the latent heat of refrigerant vapour, be heated, and the refrigerant vapour that has been absorbed latent heat becomes the solidifying water of cryogen and gets back to 1 li of high-temperature generator by air-conditioning heating water heat exchanger cryogen Condensate Controlling Equipment valve F5 and heating water heat exchanger cryogen condensate line 19.The cryogen solution that high-temperature generator is 1 li does not pass in and out and flows, and is only carrying out the circulation that simple solution is heated, cryogen evaporates, the solidifying water of cryogen is absorbed by solution again.Said process is both to have needed air-conditioning heating winter, needs again the operating mode of health hot water.When spring and autumn only needing health hot water, close air-conditioning heating water heat exchanger cryogen Condensate Controlling Equipment valve F5, obstructed air-conditioning heating water in heat exchanger tube, air-conditioning heating water heat exchanger 16 just can not worked, and unit just can be realized the workload demand that health hot water is provided separately.
When summer, for cold water and warm water are produced operation mode simultaneously, be high-temperature generator dependent operation mode: unit adopts complete machine circulation, Open valve F1, valve F2, valve F3, valve F5, valve F6, burn in the burner solution of 1 li of the heat heating high-temperature generator that produces of combustion gas or fuel oil, make the cryogen in solution absorb heat vaporization out, part refrigerant vapour enters the health hot water heat exchanger 15 on high-temperature generator top by refrigerant vapour pipeline 17, because be added with health hot water in the heat-transfer pipe of health hot water heat exchanger 15, so absorbing the latent heat of refrigerant vapour, health hot water is heated, and the refrigerant vapour that has been absorbed latent heat becomes the solidifying water of cryogen and uses cryogen Condensate Controlling Equipment valve F6 and health hot water to get back to high-temperature generator with cryogen condensate line 18 by health hot water.Another part refrigerant vapour of 1 li of generation of high-temperature generator passes into by valve F3 in the heat-transfer pipe of cryogenerator 8, and the weak solution of 8 li of cryogenerators of heating makes it to thicken, and refrigerant vapour self becomes cryogen condensed water and passes into condenser 9.Cryogenerator 8 produces a part of refrigerant vapour simultaneously, this part refrigerant vapour becomes cryogen condensed water after entering the water condensation that is cooled in condenser 9, the cryogen condensed water that condenser is 9 li leads to evaporimeter 7 through expenditure and pressure device, in 7 li, evaporimeter, by cryogenic fluid pump 14, suppressed spray, cryogen condensed water sprays on the heat-transfer pipe of evaporimeter 7 and evaporates, the heat of the cold water in heat-transfer pipe is drawn in evaporation, so just can produce out cold water from evaporimeter 7.The concentrated solution from high-temperature generator 1 and cryogenerator 8 that the refrigerant vapour of 7 li of generations of evaporimeter is absorbed 6 li of devices absorbs, and therefore concentrated solution becomes weak solution.Weak solution is transferred out by solution pump 10, wherein a part is sent to the interior heating of cryogenerator 8 through low temperature heat exchanger 11, another part is sent to the interior heating of high-temperature generator 1 after low temperature heat exchanger 11 and high-temperature heat exchanger 12, starts next round circulation.
When kind of refrigeration cycle is produced cold water, because the solidifying water of the cryogen in health hot water heat exchanger is still got back to high-temperature generator 1, do not participate in kind of refrigeration cycle, so refrigerating efficiency is lower.
