CO2用于自然复叠制冷系统的理论分析
Theoretical Analysis on Autocascade Refrigeration Systems Using Carbon Dioxide
【摘要】 对采用CO2和烷烃(R290、R600a、R600)组成的混合工质的自然复叠制冷系统应用于普冷领域进行了理论分析。研究了在CO2作为低沸点工质时,高沸点工质和中沸点工质对系统压比和性能系数COP的影响,以及这些性能参数随系统中CO2摩尔含量的变化情况。
【Abstract】 In this article, theoretical analysis is made on the autocascade refrigeration systems which use the mixtures made up of carbon dioxide and paraffins (R290, R600a, R600) and are used to common cooling fields. The influences of high boiling point refrigerants and middle boiling point refrigerants on the COP and pressure ratio of the system are investigated, and the corresponding changes of COP and pressure ratio of these mixtures with the change of carbon dioxide mole fraction are got.
