Description

一种使用太阳能和水源的溴化锂吸收式制热、制冷装置A lithium bromide absorption heating and cooling device using solar energy and water source

技术领域technical field

目前,在全国节能减排的倡导下,降低建筑能耗,特别是空调能耗尤为重要,所以寻找新型可再生能源成为暖通工作者的研究重点。我国地处北半球亚欧大陆的东部,具有比较丰富的太阳能资源。另一方面,我国地表水资源较为丰富,居世界第六位。因此,太阳能资源和地表水中含有能量可以用于空调行业。溴化锂吸收式热泵具有耗电少、能源适用性强以及环保的特点,被广泛应用于空调领域。At present, under the advocacy of national energy conservation and emission reduction, reducing building energy consumption, especially air-conditioning energy consumption is particularly important, so finding new renewable energy has become the research focus of HVAC workers. my country is located in the eastern part of the Eurasian continent in the northern hemisphere and has relatively rich solar energy resources. On the other hand, my country's surface water resources are relatively rich, ranking sixth in the world. Therefore, solar resources and surface water contain energy that can be used in the air conditioning industry. Lithium bromide absorption heat pump has the characteristics of low power consumption, strong energy applicability and environmental protection, and is widely used in the field of air conditioning.

由于单一热源驱动形式的热泵存在一定的局限性,制约着各自的发展。如果将两种或者两种以上不同形式的热泵结合起来运行,则既可以克服单一热源供热能力的不足、运行不稳定的问题,又有良好的互补和匹配性。目前,复合式热泵系统主要以双热源联合运行方式存在,主要有太阳能-土壤源热泵、太阳能-空气源热泵、太阳能-水源热泵以及太阳能-溴化锂吸收式热泵等,这些双热源联合热泵较好地解决了单一热源供热不足的问题。但是,由于它们的能效较低,应用范围较小。Due to the limitations of heat pumps driven by a single heat source, their development is restricted. If two or more heat pumps of different forms are combined to operate, it can not only overcome the problems of insufficient heating capacity and unstable operation of a single heat source, but also have good complementarity and matching. At present, the combined heat pump system mainly exists in the joint operation mode of dual heat sources, mainly including solar-soil source heat pumps, solar-air source heat pumps, solar-water source heat pumps, and solar-lithium bromide absorption heat pumps. These dual heat source combined heat pumps are better The problem of insufficient heat supply from a single heat source is solved. However, due to their low energy efficiency, the range of applications is limited.

The heating pipeline of 8 is sealed and communicated; the first absorbent outlet of the generator 8 is sealed and communicated with the absorbent inlet of the condenser 13 through the third valve 12, and the absorbent outlet of the condenser 13 is connected with the absorbent of the evaporator 15 through the expansion valve 14 The absorbent inlet is sealed and connected, the absorbent outlet of the evaporator 15 is sealed and connected with the absorber 19, and the absorbent inlet and outlet of the absorber 19 are connected with the fourth valve 17, the solution pump 18 and the solution heat exchanger 16 through a pipe sealed connection, and the solution The other pipeline of the heat exchanger 16 is in sealing communication with the second absorbent inlet and outlet of the generator 8; the cooling water inlet and outlet of the evaporator 15 are connected to the heat exchanger through the fifth valve 21 and the first cold water pump 20. One pipeline of 22 is sealed and communicated, and the other pipeline of heat exchanger 22 is sealed and communicated with outdoor water source 25 through the sixth valve 23 and the second cold water pump 24 .

所述的第二热水泵5与发生器8之间串接辅助加热器7;所述发生器8的第二路吸收剂出口通过第七阀门9与所述的冷凝器13的吸收剂进进口密封相通,发生器8的第三路吸收剂进出口通过第八阀门11、压缩机10密封相通。即可在压力较低下利用压缩机的热能,来提高吸收剂循环效率,弥补太阳能集热板供热能力的不足。其原理为:当从热水箱4出来的热水温度较高时,打开第三阀门12,关闭第七阀门9和第八阀门11,这时压缩机10不运行。当从热水箱12中出来的热水温度较低时,关闭第三阀门12,打开第七阀门9和第八阀门11,这时压缩机10运行,从发生器8出来的蒸汽都被压缩机压缩至高于发生温度的状态,压缩后的蒸汽在发生器10中放热,然后通过第七阀门9进入冷凝器13。The auxiliary heater 7 is connected in series between the second hot water pump 5 and the generator 8; the second absorbent outlet of the generator 8 passes through the seventh valve 9 and the absorbent inlet of the condenser 13 Sealed communication, the inlet and outlet of the third absorbent of the generator 8 are in sealed communication with the compressor 10 through the eighth valve 11 . The thermal energy of the compressor can be used at a low pressure to improve the cycle efficiency of the absorbent and make up for the lack of heat supply capacity of the solar collector plate. The principle is: when the temperature of the hot water coming out of the hot water tank 4 is high, the third valve 12 is opened, the seventh valve 9 and the eighth valve 11 are closed, and the compressor 10 is not running at this moment. When the temperature of the hot water coming out of the hot water tank 12 is low, close the third valve 12, open the seventh valve 9 and the eighth valve 11, at this moment the compressor 10 runs, and the steam coming out of the generator 8 is all compressed The steam is compressed to a state higher than the generation temperature, and the compressed steam releases heat in the generator 10, and then enters the condenser 13 through the seventh valve 9.

The absorption efficiency of the lithium bromide solution can be increased, so that the lithium bromide solution from the solution heat exchanger 16 enters in the form of a spray in the absorber 19, and the lithium bromide solution absorbs the heat generated by itself while absorbing the water vapor and rises. temperature. The heat exchange area of the lithium bromide solution is increased, thereby increasing the absorption efficiency.

利用溴化锂溶液浓度的变化来获取冷、热量,装置中主要工质为溴化锂溶液、水,其中溴化锂为吸收剂,水为制冷剂。利用太阳能集热板1将太阳能转为热能把水加热,从太阳能集热板出来的热水经过热水泵加压进入热水箱4储存。热水箱4储存的热水用于加热发生器8中溴化锂溶液,将制冷剂蒸汽解析出来,进入冷凝器13,在冷凝器13中,制冷剂蒸汽被冷却凝结成液体,然后通过膨胀阀14降压,送入蒸发器15,蒸发器15吸收剂吸收来自室外水源25的热量后蒸发,蒸发后的吸收剂进入吸收器19,被来自发生器8的浓的溴化锂溶液吸收,再通过溶液热交换器16进入发生器19蒸发,由此形成一个循环。The change of lithium bromide solution concentration is used to obtain cold and heat. The main working medium in the device is lithium bromide solution and water, among which lithium bromide is the absorbent and water is the refrigerant. Utilize the solar thermal collector plate 1 to convert solar energy into thermal energy to heat water, and the hot water coming out of the solar thermal collector plate is pressurized into the hot water tank 4 for storage through the hot water pump. The hot water stored in the hot water tank 4 is used to heat the lithium bromide solution in the generator 8, decomposes the refrigerant vapor, and enters the condenser 13. In the condenser 13, the refrigerant vapor is cooled and condensed into a liquid, and then passes through the expansion valve 14 Reduce the pressure and send it to the evaporator 15. The absorbent in the evaporator 15 absorbs the heat from the outdoor water source 25 and then evaporates. The evaporated absorbent enters the absorber 19 and is absorbed by the concentrated lithium bromide solution from the generator 8. The exchanger 16 enters the generator 19 for evaporation, thereby forming a cycle.
