根据热力学第二定律，热可以自发地由高温物体传向低温物体，而由低温物体传向高温物体则必须作功，正如水能够通过水泵从低处向高处流动一样，热泵系统实现了把能量由低温物体向高温物体的传递，它是以花费一部分高质能（耗电）为代价，从自然环阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具境中获取能量，并连同所花费的高质能一起向用户供热，也就是说热泵的供热量永远大于所消耗的功量，所以是综合利用能源的一种很有价值的措施。
According to the second law of thermodynamics, heat can be spontaneously transferred from high-temperature objects to low-temperature objects, and work must be done to transfer from low-temperature objects to high-temperature objects. Just as water can flow from low to high through water pumps, the heat pump system realizes the transfer of energy from low-temperature objects to high-temperature objects. It obtains energy from the natural environment at the cost of spending part of high mass energy (power consumption), Together with the high-quality energy spent, it provides heat to users, that is to say, the heat supply of the heat pump is always greater than the work consumed, so it is a very valuable measure for comprehensive utilization of energy.
