AS:one truck drivs 10T boiled water to a big-arch she lter greenhouse 5Km away,,consuming srveral hters of gasoline ,and,afrter draining the water ,return to the original place, making a great dea l of heat heergy shipped with lnly a little mechanical energy (vehicle ) .The heat making process of the heat pump is some how like this truck’s”” heat energyshipmentprocess,only except that the “shipment”prodcess.only except that the “shipment”process can notbe the end and electric energy can be accurately measurde by means of calculation .This means a process of heat energy indirect shipment with the working medium as the acrrier and the raito between the “”shipment capactiy and the electric comnsumption by the heat pump is callde ad the enregy-gfficiency ration,expressed by a COP value,which ca be up to over 450% at 25C,in general Hence, it follows the in verse Carnots principle adn does not villate the law of energy conservation for the teat pump to make wateer heattedf width only a little electric energy comsumed.
