Problems solved by technology

Flat-panel solar water heaters mostly use indirect heating. Because the heat transfer medium is relatively viscous, the shape design of the heating liner or jacket is unreasonable, resulting in low heat conduction efficiency.
Moreover, the use of solar water heaters is easily restricted by weather and day and night.
[0003] At present, there are many patents on solar water heater tanks, but there is no water heater tank that can use liquid antifreeze as the heat transfer medium and the heating liner is placed horizontally inside the water tank. Discover

Embodiment Construction

[0013] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] The hot water storage tank is connected with a flat solar heat collector, the heat storage chamber 2 is filled with phase change heat storage material, and the heating liner 7 is filled with a heat transfer medium with a low boiling point, and the heat transfer medium flows into the flat solar heat collector from the return pipe 8 The device absorbs heat. The heated and vaporized heat-conducting medium enters the heating inner tank 7 from the liquid inlet pipe 6, and releases heat and liquefies in the heating inner tank 7. The water in the water storage chamber 3 absorbs heat from the heating liner 7 and heats up. The liquefied heat transfer medium flows back from the return pipe 8 to the flat solar heat collector. When the water temperature exceeds 50°C, the phase change heat storage material in the heat storage chamber 2 absorbs a large am...

Abstract

The invention discloses a heat storage water tank. The water tank is characterized in that a heating liner is arranged inside a water tank; phase change heat storage media with melting points being 50 DEG C are filled in a jacket of the water tank; and media with boiling points being about 30 DEG C are filled in the heating liner. By adopting the design, the circulation speed of heat-conducting media can be increased, the speed of heat exchange between a solar heat collector and the water tank can be increased, and when the hot water temperature is higher than 50 DEG C, heat storage materials store plenty of heat absorbed from hot water; and when the water temperature decreases, the heat storage materials release heat to stabilize the water temperature at about 50 DEG C.

Description

technical field [0001] The invention relates to solar heat utilization technology and phase change heat storage technology, in particular to a heat storage tank for solar water heaters. The water tank is provided with a heating liner and a phase change heat storage medium is installed in the jacket of the water tank. Background technique [0002] In the field of solar thermal utilization, solar water heaters have appeared in a variety of mature products including vacuum tube water heaters and flat plate water heaters. Flat plate solar water heaters are rapidly opening up the market due to their longer service life and easy installation methods. Flat-panel solar water heaters mostly use indirect heating. Because the heat transfer medium is relatively viscous, the shape design of the heating liner or jacket is unreasonable, resulting in low heat conduction efficiency. Moreover, the use of solar water heaters is easily restricted by weather and day and night. [0003] There ar...
