The invention discloses a natural circulation type window type solar water heater device and a control method thereof. Two heat collecting plates connected in series are arranged. Water inlets / outlets for the two heat collecting plates are formed in the top and bottom of a water storage tank correspondingly, and then the angle of the heat collecting plates and opening and closing of the water inlets / outlets are correspondingly adjusted according to the flowing speed of water flow in a water heater and changes of the water temperature. The natural circulation type window type solar water heater device and the control method thereof can overcome the defects in the prior art and improve the efficiency of the solar water heater.
Description
technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a natural circulation window type solar water heater device and a control method thereof. Background technique [0002] In order to save installation space, window-type solar water heaters have been more and more widely used. There are two types of window solar water heaters, natural circulation and forced circulation. Among them, the natural circulation type is more common among ordinary household users due to its simple structure. However, after the external heat collecting plate of the solar water heater with this structure absorbs solar energy, the internal water flow will expand inside the heat collecting plate, forming an "air resistance effect", which will cause the water flow circulation of the entire solar water heater to attenuate or even be interrupted, reducing the the efficiency of solar water heaters. Contents of the invention [0003] The technical...
