Studies the heat pump systems exploiting the freezing heat 研究了利用冷水凝固热的热泵技术。
2.
Calculation results show that by the heat pump technology , the freezing heat can be used economically and practicably , and therefore be taken as a low temperature heating source for buildings 计算结果表明,热泵可以在经济、可行的前提下大量利用冷水凝固热,作为建筑的低温供暖热源。
