根據(jù)熱力學(xué)第二定律，熱可以自發(fā)地由高溫物體傳向低溫物體，而由低溫物體傳向高溫物體則必須作功，正如水能夠通過水泵從低處向高處流動一樣，熱泵系統(tǒng)實(shí)現(xiàn)了把能量由低溫物體向高溫物體的傳遞，它是以花費(fèi)一部分高質(zhì)能（耗電）為代價(jià)，從自然環(huán)境中獲取能量，并連同所花費(fèi)的高質(zhì)能一起向用戶供熱，也就是說熱泵的供熱量永遠(yuǎn)大于所消耗的功量，所以是綜合利用能源的一種很有價(jià)值的措施。根據(jù)熱力學(xué)第二定律，熱可以自發(fā)地由高溫物體傳向低溫物體型槽模具 一次性止血帶 保定水處理設(shè)備 一次性止血帶 保定空壓機(jī) 北京真空泵，而由低溫物體傳向高溫物體則必須作功，正如水能夠通過水泵從低處向高處流動一樣，熱泵系統(tǒng)實(shí)現(xiàn)了把能量由低溫物體向高溫物體的傳遞，它是以花費(fèi)一部分高質(zhì)能（耗電）為代價(jià)，從自然環(huán)境中獲取能量，并連同所花費(fèi)的高質(zhì)能一起向用戶供熱，也就是說熱泵的供熱量永遠(yuǎn)大于所消耗的功量，所以是綜合利用能源的一種很有價(jià)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
