1, no electricity pressurization: Sun Yu's original jet pressurization technology uses the vacuum suction between cold and hot water to pressurize, and the cold and hot water evenly mix the jet, so that the hot water is strong and smooth, preventing the cold water from flowing backwards and bringing surfing-level bathing. The water heater only needs to set the water temperature once, and the system will automatically remember and realize constant temperature water discharge. Products use solar energy, clean and pollution-free, no electricity, green and energy-saving.
2. Energy-gathering Antarctic tube: Solar rain solar water heater adopts a new type of energy-gathering Antarctic tube, and its unique multi-spectral energy-gathering film layer comprehensively uses high vacuum manufacturing technology, three-target coating technology and frequency conversion absorption technology. Under full illumination, the internal temperature of the vacuum tube is as high as 250℃, and the heat-absorbing film has good oxidation resistance, which can accumulate energy for 25 years (ordinary vacuum tube 15 years), even in the Antarctic.
3. Thermal insulation wall: The patented thermal insulation wall technology is adopted for the thermal insulation of fluorine-free water tank of solar rain solar water heater, and the comprehensive thermal insulation performance is improved by more than half. According to the testing data of national institutions, solar water heaters can maintain a constant temperature of over 40℃ 100 hour even in the absence of sunlight, and one day's heat absorption can guarantee three days' hot water.
4. Intelligent control operating system: Solar rain solar water heater adopts a unique humanized intelligent system, which can intelligently adjust the temperature of the water heater. Intelligent design: Sunrain makes the ratio of instant heating area, volume and heat preservation of solar water heater reach a good state through advanced unsteady thermal efficiency algorithm.
