In the chest of no pressure tank have been set a prtesurrized copper coil,the water of the tank can be naturally cycle with that of collector’s. Washing water turn hot through the heat exchange between the copper coil and the hot water in the tank,and so can have pressure spray. Copper coil is increased cost, but the heat transfer ability greatly increased.In order to ensure a continuous bath ,The water temperature in tank and heat transfer area of copper coil is determined.
The water in tank only play the role of endothermic and exothermic.Water capacity in storage tank keeps constant.Using water go into solar storage tank through the cold water inlet of the coil. Cold water absorb heat energy of hot water in starage tank to rise itseft temperature.( temperature difference
