摘要
在60~140℃的冷凝温度范围,对21种环境友好、温度压力水平适宜的流体及CFC11、CFC114进行了中高温热泵理论循环对比分析。结果表明,HFC254cb、HC600、HFC143、HFE134、HFC236ea、HFC236ca、HFC245ca、HFE143、HFE245fa、HFC245fa等工质的理论循环性能较优。
The performances of 21 chlorine-free environmentally benign fluids in the theoretical heat pump cycles of condensing temperatures ranged from 60℃to 140℃ were comparatively assessed with CFC11 and CFC114. It was shown that HFC254cb, HC600, HFC143, HFE134, HFC236ea, HFC236ca, HFC245ca, HFE143, HFE245fa and HFC245fa are promising working fluids for moderate and high temperature heat pump systems.
