Compact Solar Water Heater Should Have Water Temperature Display
The compact solar water heater is divided into two types: the flat type and the glass vacuum tube type, according to the system operation mode, divided into the natural circulation and the forced circulation two kinds of systems. The natural circulation compact solar water heater system has been widely applied in solar energy industry because of its simple operation mode, single function and convenient maintenance. Compact Pressure Solar Water Heater Traditional household type natural circulation plate compact solar water heater products, the water tank and the plate collector in the structure design only need to set up a cycle and a lower circulation port, can satisfy the natural circulation hot siphon request, in order to ensure the natural circulatory system smooth, avoids the circulation gas resistance, the bracket design must side low, side high, forms has the 2°3° The circulation angle, Compact Pressure Solar Water Heater namely the upper circulation port direction is higher than the lower circulation port direction, and the compact solar water heater system installs, has certain selectivity to the construction installs the roof. Usually the installation of compact solar water heaters Roofing, roofing waterproof for easy drainage, there is a certain degree of water gradient. And the pan-water gradient is in all directions, such as the installation of compact solar water heaters, the next cycle of the direction of the mouth than the upper circulation of the direction of higher, Compact Pressure Solar Water Heater the emergence of the reverse slope, will result in a compact solar water heater system operation is not normal, the water temperature is not high. At the same time, the traditional plate compact solar water heater water tank and collector plate, is not a short distance connection, the upper and lower circulation pipeline is longer, the pipe bulk heat increase, which is unfavorable to the thermal performance of the plate solar heat system. In order to overcome the existing technical deficiencies, it is necessary to develop a compact solar water heater with short cycle path and high thermal cycling efficiency.
Compact solar water heaters should have the following characteristics:
1: The tank inside the material to use sanitary, non-toxic, not rusty SUB304 high-quality stainless steel materials, or the use of enamel liner;
2: The tank liner seals should use the endurance, long life of high-grade food hygiene silicone rubber material, water tank shell dust Ring also has anti-aging and long life requirements;
3: The quality and performance of the vacuum tube should conform to the requirements of the national standard of gb/t17049-2005 "all glass evacuated solar collector tube";
4: Water tank insulation layer required to foam evenly, no gap, Compact Pressure Solar Water Heater heat insulation foam can be used in the whole polyurethane foam or polyurethane and polystyrene compound foaming;
5: If the compact solar water heater adopts auxiliary heat source, its electric heating should meet the requirement of safe operation.
6: The bracket must ensure that the tank is filled with water without shaking and any deformation, while ensuring long-term use;
7: The compact solar water heater can use automatic control instrument, Compact Pressure Solar Water Heater can also use artificial Sheung Shui;
8: Compact Solar water heaters should be water temperature display, Compact Pressure Solar Water Heater or automatic control of water temperature meters, to prevent the use of scald accidents.
