Problems solved by technology
The disadvantage of the above-mentioned wall-mounted solar water heater is that the hot water storage tank is a pressurized water tank. Due to the large daily temperature difference, the pressurized water tank made of metal and its welding parts will expand with heat and contract with cold due to the change in temperature difference, resulting in fatigue. Effect, the fatigue effect of the metal material and welding parts is limited. If it exceeds its limit, the pressurized water tank will leak. some economic loss

The invention relates to a non-pressure bearing operation wall mounting type solar water heater hot water supply pressurization control device. The technical points of the device are that an increasing pump which is arranged on a hot water supply and water supplementing pipe is utilized; when using hot water, an infrared sensor sends signals into a controller regulator, and then the controller regulator gives out commands to start the increasing pump to work. The beneficial effect of the device is that a heat storage water tank operates in the non-pressure bearing status; the service life of the heat storage water tank is greatly prolonged; and the manufacture cost is greatly reduced; in addition, the device has the function of leading cool water in the hot water supply and water supplementing pipe to automatically cycle to the heat storage water tank and solves the waste phenomenon that before using hot water, the cool water in the hot water supply and water supplementing pipe is firstly let out.
Description
technical field [0001] The invention relates to a pressure-free wall-mounted solar water heater hot water pressure control device, which is suitable for split and integral wall-mounted solar water heaters. Background technique [0002] At present, the commonly used wall-mounted solar water heaters include hot water storage tanks, solar collectors, heat exchangers located in the hot water storage tanks, hot water supply pipes, water supply pipes and other components; connected. Its working process is as follows: the medium in the heat exchanger is heated by the solar collector, and then exchanges heat with the tap water in the hot water storage tank through the heat exchanger to heat the tap water in the water storage tank. When using hot water, it needs to use The top water mode operates, that is, the tap water enters the hot water storage tank through the water replenishment pipe, and the pressure of the tap water is used to make the hot water flowing out of the hot water ...
