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。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型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵，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 transferred spontaneously from a high-temperature object to a low-temperature object, and work must be done to transfer heat from a low-temperature object to a high-temperature object. Just as water can flow from a low place to a high place through a pump, the heat pump system realizes the transfer of energy from a low-temperature object to a high-temperature object. It obtains energy from the natural environment at the cost of some high-quality energy (power consumption), Together with the high-quality energy spent, it provides heat to users, that is to say, the heat supply capacity of the heat pump is always greater than the work consumed, so it is a very valuable measure for the comprehensive utilization of energy
