Description

单工质联合循环热泵装置Single working substance combined cycle heat pump device 技术领域：Technical field:
本发明属于制冷与热泵技术领域。The invention belongs to the technical field of refrigeration and heat pumps.
背景技术：Background technique:
冷需求、热需求和动力需求，为人类生活与生产当中所常见；其中，利用机械能转换为热能是实现制冷和高效供热的重要方式。一般情况下，制冷时冷却介质的温度是变化的，制热时被加热介质的温度往往也是变化的；利用机械能制热时，很多时候被加热介质同时具有变温和高温双重特点，这使得采用单一热力循环理论实现制冷或供热时存在着性能指数不合理、供热参数不高、压缩比较高、工作压力太大等多个问题。Cold demand, heat demand and power demand are common in human life and production; among them, the use of mechanical energy to convert heat energy is an important way to achieve cooling and efficient heating. In general, the temperature of the cooling medium changes during refrigeration, and the temperature of the heated medium often changes during heating; when using mechanical energy to heat, often the heated medium has the dual characteristics of variable temperature and high temperature at the same time, which makes the use of a single Thermal cycle theory has many problems such as unreasonable performance index, low heating parameters, high compression ratio, and too much working pressure when it realizes cooling or heating.
具体来看，基于逆向朗肯循环的蒸汽压缩式热泵装置，当放热主要依靠冷凝过程时，工质与被加热介质之间温差损失大；同时，冷凝液的降压过程损失较大或利用代价高；采用超临界工况时，压缩比较高，使得压缩机的制造代价大，安全性降低等；两种情况下，对获取低温热负荷的副作用难以消除。同样地，基于逆向布雷顿循环的气体压缩式热泵装置，要求压缩比较低，这限制了供热参数的提高；同时，低温过程是变温的，这使得制冷或制热时低温环节往往存在较大的温差损失，性能指数不理想。Specifically, based on the vapor compression heat pump device of the reverse Rankine cycle, when the heat release mainly depends on the condensation process, the temperature difference between the working fluid and the heated medium loses a lot; at the same time, the condensate loses a lot in the depressurization process or is used The cost is high; when the supercritical working condition is adopted, the compression ratio is high, which makes the manufacturing cost of the compressor high and the safety is reduced; in both cases, it is difficult to eliminate the side effects of obtaining low-temperature heat load. Similarly, the gas compression heat pump device based on the reverse Brayton cycle requires a relatively low compression, which limits the improvement of heating parameters; at the same time, the low temperature process is variable temperature, which makes the low temperature link of cooling or heating often large The temperature difference loss, the performance index is not ideal.
不可否认的是，依靠蒸发过程吸收低温热负荷是蒸汽压缩式热泵的优点，变温放热是气体压缩式热泵的优点；如果能够保留二者的优点，充分利用冷凝液的显热，消除冷凝液降压的副作用，那么得到的热泵装置将具有合理的性能指数，从而扩大其应用场合。基于综合考量，从简单、主动和高效地利用机械能进行制冷或制热的原则出发，力求制冷或热泵装置的简单、主动和高效化，本发明提出了单工质联合循环热泵装置。It is undeniable that relying on the evaporation process to absorb the low temperature heat load is the advantage of the vapor compression heat pump, and the variable temperature heat release is the advantage of the gas compression heat pump; if the advantages of both can be retained, the sensible heat of the condensate can be fully utilized to eliminate the condensate As a side effect of lowering the pressure, the obtained heat pump device will have a reasonable performance index, thereby expanding its application occasions. Based on comprehensive considerations, starting from the principle of simple, active and efficient use of mechanical energy for cooling or heating, and striving to make the cooling or heat pump device simple, active and efficient, the present invention proposes a single working substance combined cycle heat pump device.
