Compared with the ordinary vacuum glass tube solar water heater, the split flat plate pressure-bearing solar water heater has the following six characteristics:
Based on the principle of absorbing solar energy, the collector adopts copper-aluminum plate core and the working medium circulates to collect heat. The water tank is heated to 55℃ and equipped with automatic electric heating system, which is not affected by rainy weather and can provide users with sanitary hot water all day.
The thermal circulating copper tube is bent once, which completely eliminates the welding oxidation phenomenon, fundamentally ensures the manufacturing quality of the heat collector, and fills the gap in the field of welding-free processing of heat absorbing copper tubes in China.
The heat storage tank adopts the most advanced crystal liner, never scaling, and the pressure is 0.8Mpa. The system is operated by intelligent controller and fully automatic, which can meet the demand of multi-point water use at the same time.
The heat preservation of the box is made of polyurethane foam by high pressure molding, with a thickness of 50mm and a heat preservation time of 72 hours. In continuous rainy days without sunshine, the water temperature drops by 2-3℃ every 24 hours. The service life of hot water storage tank is as long as 30 years.
The working medium expansion tank equipped with water heater is safe and reliable, the heat collecting medium does not leak, it is resistant to low temperature and freezes at MINUS 30 degrees, which is the most advanced production technology in China at present.
The patented technology of high-efficiency heat conduction improves the heat cycle transfer efficiency between the heat collector and the thermal storage water tank. The solar energy absorption rate of the heat absorber is not less than 0.68, and the total heat loss coefficient (including the heat loss of the heat collector) is only 7%-9%.
Humanized exterior design can also be perfectly combined with decorative fence to achieve the realm of architectural integration. Nowadays, split wall-mounted flat pressure solar water heaters are being accepted by more and more consumers. ?
