Shanghai Hitachi electrical appliances co., LTD. Heat pump propulsion office manager LeGong - compared to the reporter analyzed the working principle of three kinds of water heater, air can heat pump water heater energy saving effect is obvious.

According to LeGonheat pump wins, air can heat pump water heater is the use of reverse carnot cycle principle, through the work of compressor, the absorbing heat from the air, and then will absorb heat, together with the compressor power consumption of water, so as to obtain hot water equipment. Electric water heater is only through the electric heating rod fever, to convert electrical energy into heat energy to heat water. Water heater burning gas by burning natural gas or coal gas, to convert chemical energy into heat energy so as to achieve the
purpose oheat pumpf preparing hot water.

Because can absorb heat from the air free of charge, so the air can heat pump water heater ?
