Description

逆向单工质蒸汽联合循环Reverse single working substance steam combined cycle 技术领域：Technical field:
本发明属于热力学、制冷与热泵技术领域。The invention belongs to the technical fields of thermodynamics, 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性能指数不合理；这些存在的问题是——性能指数不合理，供热参数不高，压缩比较高，工作压力太大。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. Under normal circumstances, the temperature of the cooling medium changes during cooling, and the temperature of the heated medium often changes during heating. When using mechanical energy to heat, the heated medium often has the dual characteristics of variable temperature and high temperature at the same time, which makes the use of a single The thermal cycle theory realizes the unreasonable performance index for cooling or heating; these problems are-unreasonable performance index, low heating parameters, high compression ratio, and too much working pressure.
从基础理论看，长久以来存在重大不足：(1)采用逆向朗肯循环为理论基础的蒸汽压缩式制冷或热泵循环，放热主要依靠冷凝过程，导致放热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。(2)采用逆向布雷顿循环为理论基础的气体压缩式制冷或热泵循环，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。From the basic theory, there have been major shortcomings for a long time: (1) The vapor compression refrigeration or heat pump cycle based on the reverse Rankine cycle is used. The heat release mainly depends on the condensation process, resulting in the heat release between the working fluid and the heated medium The temperature difference loss is large; at the same time, the pressure reduction process of the condensate has a large loss or high utilization cost; when the supercritical working condition is adopted, the compression ratio is high, which makes the compressor expensive to manufacture and reduces the safety. (2) The gas compression refrigeration or heat pump cycle 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 cooling or heating process low temperature The link often has a large temperature difference loss, and the performance index is not ideal.
