【摘要】 对利用适宜的循环工质实现蒸气压缩式制冷热泵近卡诺循环进行了分析,包括基本思路、可行性分析、典型工质及其特性,并在相同设备条件和工作温度下,对近卡诺循环制冷热泵和普通循环制冷热泵(R22为工质)的效率进行了计算比较,最后对进一步需做的工作进行了探讨。更多还原

【Abstract】 When refrigerators and heat pumps run along Carnot cycle, their energy efficiency is highest. Method to help refrigerators and heat pumps running near Carnot cycle by way of refrigerant design is given and it can make the refrigerating efficiency higher than common cycle when components and working temperature are the same. Relative research about expander and other components is also discussed.更多还原
