技术领域technical field
本发明属于空调系统技术领域，具体涉及一种吸收式热泵与蒸发冷却结合的能源综合应用系统。The invention belongs to the technical field of air conditioning systems, and in particular relates to an energy comprehensive application system combining absorption heat pumps and evaporative cooling.
背景技术Background technique
吸收式热泵是利用工质的吸收循环实现热泵功能的装置，它是利用热能直接驱动，而不是依靠电能和机械能等其它能源。目前，工业用能主要是依赖化石类燃料，大量的工业废热常常无法得到有效的回收利用，许多场合应用工业吸收式热泵在提高能源利用率、降低温室气体排放量等方面起到很好的效果；并且，吸收式热泵在回收利用低品位能源的同时，又可以制得低温冷媒水。The absorption heat pump is a device that uses the absorption cycle of the working fluid to realize the heat pump function. It is directly driven by thermal energy instead of relying on other energy sources such as electrical energy and mechanical energy. At present, industrial energy mainly relies on fossil fuels, and a large amount of industrial waste heat is often unable to be effectively recycled. In many occasions, the application of industrial absorption heat pumps has played a very good role in improving energy utilization and reducing greenhouse gas emissions. ; Moreover, the absorption heat pump can produce low-temperature refrigerant water while recycling low-grade energy.
蒸发冷却技术是一种利用水蒸发吸热制冷的技术。现有蒸发冷却设备都是利用循环水对空气降温，无法实现除湿功能，从而阻碍了蒸发冷却设备在高湿地区的应用。Evaporative cooling technology is a technology that uses water evaporation to absorb heat and cool down. The existing evaporative cooling equipment uses circulating water to cool the air, which cannot achieve the dehumidification function, thus hindering the application of evaporative cooling equipment in high-humidity areas.
将吸收式热泵蒸发冷却结合，利用吸收式热泵回收低品位热源(工业余/废热)，制取60℃左右的高温热水和7℃～9℃的冷媒水。其中，高温热水用于工业或民用生活热水，冷媒水为复合式蒸发冷却空调机组的直接蒸发冷却单元提供冷量，使其具有除湿功能，从而能在高湿地区得以应用。由此可见，将吸收式热泵与蒸发冷却结合而构成的综合系统既能提供生活热水，又能对被处理空间进行供冷，有效实现了“一机两用”。Combining the absorption heat pump with evaporative cooling, the absorption heat pump is used to recover low-grade heat sources (industrial waste/waste heat) to produce high-temperature hot water at about 60°C and refrigerant water at 7°C to 9°C. Among them, the high-temperature hot water is used for industrial or civil domestic hot water, and the refrigerant water provides cooling capacity for the direct evaporative cooling unit of the compound evaporative cooling air-conditioning unit, so that it has a dehumidification function and can be applied in high-humidity areas. It can be seen that the comprehensive system composed of the combination of absorption heat pump and evaporative cooling can not only provide domestic hot water, but also provide cooling for the treated space, effectively realizing "one machine with two uses".

填料式直接蒸发冷却单元内的循环水箱b7中设置有冷媒水盘管a6，且冷媒水盘管a6通过循环水管a32、循环水管b33与蒸发器26内的冷媒水盘管b35构成闭合回路，能使循环水箱b7内的喷淋水温低于被处理空气的湿球温度即亚湿球温度，从而使得直接蒸发冷却单元具有冷却除湿功能。The circulating water tank b7 in the packed direct evaporative cooling unit is provided with a refrigerant water coil a6, and the refrigerant water coil a6 forms a closed circuit through the circulating water pipe a32, the circulating water pipe b33 and the refrigerant water coil b35 in the evaporator 26, which can The temperature of the spraying water in the circulating water tank b7 is lower than the wet bulb temperature of the treated air, ie the sub-wet bulb temperature, so that the direct evaporative cooling unit has the function of cooling and dehumidification.
2)水循环处理过程具体如下：2) The water cycle treatment process is as follows:
循环水箱a2内的循环水在循环水泵a3加压作用下输送到水处理器a4中，循环水经水处理器a4净化处理后由第一供水管输送至布水器a10中，并由布水器a10内的喷嘴将水喷淋到每根换热管14的外壁上，喷淋出来的水依靠重力作用向下流动，润湿每根换热管14的外壁并在每根换热管14的外壁上形成均匀的水膜；二次空气与换热管14外壁上的水膜进行热湿交换，从而对一次空气进行等湿预冷；最后，所有换热管14上多余喷淋水在重力作用下流回循环水箱a2中，如此不断循环。The circulating water in the circulating water tank a2 is sent to the water processor a4 under the pressure of the circulating water pump a3, and the circulating water is purified by the water processor a4 and then sent to the water distributor a10 by the first water supply pipe, and the The nozzles in a10 spray water onto the outer wall of each heat exchange tube 14, and the sprayed water flows down by gravity, wets the outer wall of each heat exchange tube 14 and spreads on the outer wall of each heat exchange tube 14 A uniform water film is formed on the outer wall; the secondary air exchanges heat and moisture with the water film on the outer wall of the heat exchange tube 14, thereby performing isohumid precooling on the primary air; finally, the excess spray water on all the heat exchange tubes 14 is Under the action, it flows back into the circulating water tank a2, so that it circulates continuously.
同理，循环水箱b7内的循环水在循环水泵b5加压作用下输送到水处理器b11内，循环水经水处理器b11净化处理后通过布水器b12内喷头喷淋到填料9上，喷淋出来的水靠重力作用向下流，润湿整个填料9并形成均匀的水膜；一次空气(即被处理空气)与填料9上的水膜充分进行热湿交换后，实现冷却除湿；最后，填料9上多余的喷淋水在重力作用下流回循环水箱b7中，如此不断循环。Similarly, the circulating water in the circulating water tank b7 is transported to the water processor b11 under the pressure of the circulating water pump b5, and the circulating water is purified and treated by the water processor b11 and then sprayed onto the filler 9 through the inner nozzle of the water distributor b12. The sprayed water flows down by gravity, wets the entire packing 9 and forms a uniform water film; the primary air (that is, the air to be treated) and the water film on the packing 9 fully perform heat and moisture exchange to realize cooling and dehumidification; finally , the redundant spray water on the filler 9 flows back in the circulating water tank b7 under the action of gravity, so that the circulation continues.
冷媒水在冷媒水盘管a6与冷媒水盘管b35之间循环，完成蒸发器26与循环水箱b7内的循环水的换热。The refrigerant water circulates between the refrigerant water coil a6 and the refrigerant water coil b35 to complete the heat exchange between the evaporator 26 and the circulating water in the circulating water tank b7.
3)吸收式热泵的工作过程：3) Working process of absorption heat pump:
a.吸收剂循环过程：在吸收器20中，吸收剂吸收来自蒸发器26内的低压制冷剂蒸汽，成为含有制冷剂浓度较高的制冷剂-吸收剂二元溶液；制冷剂-吸收剂二元溶液经发生器泵22加压后由第一管道G1送入溶液热交换器24中，再从溶液热交换器24中经第二管道G2送到发生器16中；在发生器16中设置有加热盘管15，主要用于回收利用低品位热源的热量，使制冷剂-吸收剂二元溶液中的制冷剂大量汽化为高温高压的气态制冷剂并进入到冷凝器17中，而剩下的含有制冷剂浓度较低的制冷剂-吸收剂二元溶液则经第四管道G4流入到溶液热交换器24内，并把热量传给来自吸收器20的制冷剂-吸收剂二元溶液，最后经膨胀阀b23节流减压后由第三管道G3流回吸收器20内，如此不断循环。a. Absorbent circulation process: In the absorber 20, the absorbent absorbs the low-pressure refrigerant vapor from the evaporator 26 to become a refrigerant-absorbent binary solution containing a relatively high concentration of refrigerant; After the primary solution is pressurized by the generator pump 22, it is sent into the solution heat exchanger 24 by the first pipeline G1, and then sent to the generator 16 through the second pipeline G2 from the solution heat exchanger 24; There is a heating coil 15, which is mainly used to recover and utilize the heat of a low-grade heat source, so that a large amount of refrigerant in the refrigerant-absorbent binary solution is vaporized into a high-temperature and high-pressure gaseous refrigerant and enters the condenser 17, while the remaining The refrigerant-absorbent binary solution containing a relatively low refrigerant concentration flows into the solution heat exchanger 24 through the fourth pipeline G4, and transfers heat to the refrigerant-absorbent binary solution from the absorber 20, Finally, it flows back into the absorber 20 through the third pipeline G3 after being throttled and decompressed by the expansion valve b23, and the cycle continues like this.
b.制冷剂循环过程：从发生器16出来的高温高压制冷剂蒸汽进入冷凝器17中，并向供热管21传递热量成为高压常温的液体，接着经膨胀阀a18节流后进入蒸发器26内，在蒸发器26内，液态制冷剂在蒸发器泵25加压作用下经第五管道G5输送至冷剂喷淋系统27，经冷剂喷嘴喷出，洒在冷媒水盘管b35外表面，吸收冷媒水的热量后汽化为冷剂蒸汽，被吸收器20内的吸收剂吸收后在发生器泵22作用下经第一管道G1送入发生器16中，而部分来不及汽化的制冷剂与来自冷凝器17的液态制冷剂一起被蒸发器的水盘收集后重新送入冷剂喷淋系统27，如此不断循环。b. Refrigerant cycle process: the high-temperature and high-pressure refrigerant vapor from the generator 16 enters the condenser 17, and transfers heat to the heat supply pipe 21 to become a high-pressure and normal-temperature liquid, and then enters the evaporator 26 after throttling by the expansion valve a18 In the evaporator 26, the liquid refrigerant is transported to the refrigerant spray system 27 through the fifth pipe G5 under the pressure of the evaporator pump 25, sprayed through the refrigerant nozzle, and sprinkled on the outer surface of the refrigerant water coil b35 After absorbing the heat of the refrigerant water, it is vaporized into refrigerant vapor, and after being absorbed by the absorbent in the absorber 20, it is sent to the generator 16 through the first pipeline G1 under the action of the generator pump 22, and part of the refrigerant that is too late to vaporize and The liquid refrigerant from the condenser 17 is collected by the water pan of the evaporator and sent to the refrigerant spraying system 27 again, so that the cycle continues.
