热泵热泵heatpump将低温热源的热量转移到温度高于环境温度的物体，从而获得热量的机器和设备。在空气调节设备中，热泵的工作过程与制冷机相仿，但它是向高于环境温度的物体供给热量，例如向建筑物供暖、供应生活或某些生产过程用的热水等。热泵的低温热源最常用的是环境介质(空气或地面水)的热量，也可用地热或生活过程中排放的废汽、废水和废油等的热量。压缩式热泵主要由压缩机、冷凝器、节流阀和蒸发器组成，用一般的制冷剂(氨或氟利昂)作为工质。衡量热泵工作有效性的一个重要技术指标是热量变换系数，它等于热泵向高温物体供热的速率与压缩机消耗功率的比值。热量变换系数随热泵的工作温度而变化。蒸发温度越低，冷凝温度越高则热量变换系数越小。所以，在供热温度较高而低温热源温度较低的情况下，用热泵供热不很经济。在电力供应不足和电费价格较高的情况下，压缩式热泵不宜大量使用。应用压缩式制冷机和压缩式热泵的工作原理，可以组成热泵型空调机组。夏季按制冷循环工作，可使房间降温；冬季按热泵循环工作，可向房间供热。
