热泵可以有效地利用自然环境资源和低温位热源,因此热泵可以大量节约燃料和提高能源利用率。本文主要介绍了压缩式热泵的工作原理;推导了热泵供热与直接用电加热和锅炉加热的经济性比较公式、并进行了对比;结合实例对常用热泵工质进行了比较,结论认为R12、R114、R142是比较好的热泵工质;最后简单介绍了热泵的一般应用范围及在空调、冷藏工程上的实例。
Heat pump can effectively use the natural environment resources and low-temperature heat source, so the heat pump can save a lot of fuel and improve energy efficiency. This paper mainly introduces the working principle of the compression heat pump; deduces the economic comparison formula between the heat pump heating and the direct electric heating and the boiler heating, and makes a comparison; compares the common heat pump working fluid with examples, concludes that R12, R114, R142 is a good heat pump working fluid; Finally, a brief introduction to the general application of heat pump and air conditioning, refrigeration engineering examples.
