| 摘 要： | 在对中高温热泵进行了大量的试验研究之后，发现了四种有别于理论分析结果的试验现象，如冷凝温度下降，COP也下降；压缩机转数降低，COP降低等。针对这些特殊现象，进行了详细的描述、分析和较合理的解释，最终给出了对中高温热泵在设计和实际运行中的一些建议，这将有助于中高温热泵系统的安全高效运行。

| Abstract: | Four kinds of phenomena in moderate and high temperature heat pumps are found, which those are clear difference between theory and experiments, for example, the COP may be reduced with condensation temperature drop or working frequency of compressor decreasing. Those phenomena were described in detail and analyzed, some possible explains were presented. Based on those conclusions, some advises was given and it will be helpful for de- signing and running of moderate and high temperature heat pumps. |
