Solar water heater is solar energy into heat energy device, the water from low temperature to high temperature, to meet people in life, production of hot water use. Solar water heaters, according to the structure is divided into vacuum tube solar water heaters and flat-panel solar water heaters, mainly vacuum tube solar water heaters, accounting for 95% of domestic market share. Vacuum tube household solar water heater is a collection of heat pipes, storage tanks and scaffolding and other related components, the solar energy into heat mainly rely on the vacuum tube, vacuum tube using hot water floating cold sinking principle, the water microcirculation and Reached the required hot water.
Collector
System in the collection of components. Its function is equivalent to electric water heater in the electric tube. And electric water heaters, gas water heaters, the difference is that the solar collector is the use of the sun's radiant heat, so the heating time can only be reached when the sun reaches a certain value.
Currently the most common on the Chinese market is all-glass solar vacuum tube. Structure is divided into outer tube, inner tube, outer tube coated with a selective absorption coating. Plate collector collector panels coated with black chrome and other heat-absorbing film, the metal pipe is welded to the collector plate, plate collector vacuum tube collector slightly higher cost, flat collector in recent years showed an upward trend , Especially in high-rise residential balcony solar water heater has a unique advantage. All-glass solar vacuum tube is generally made of high-borosilicate 3.3 special hard glass, selective heat-absorbing film using vacuum sputtering selective coating process.
Insulation tank
Container for storing hot water. The hot water collected by the collector must be stored in a holding tank to prevent heat loss. The capacity of a solar water heater refers to the water capacity that can be used in a water heater, excluding the capacity that can not be used in a vacuum tube. For pressure-type solar water heaters, its capacity refers to the heat exchange medium capacity.
Solar water heater insulation tank from the liner, insulation, tank shell composed of three parts.
Tank liner is an important part of the storage of hot water, its material strength and corrosion resistance is essential. Stainless steel, enamel and other materials on the market. Insulation material insulation is directly related to the insulation effect, especially important in the cold season. The better insulation method is polyurethane foam insulation process. Shell is generally color plate, galvanized sheet or stainless steel plate.
Insulation tank requires good insulation effect, corrosion resistance, water quality and clean.
Bracket
Support the collector and the insulation tank shelf. Requires a solid structure, high stability, snow-resistant, anti-aging, no rust. Material is generally stainless steel, aluminum or steel spray.
Connect the pipe
Solar water heater is the first cold water into the heat storage tank, and then through the collector heat will be delivered to the insulation tank. The hot water storage tank is connected with indoor cold and hot water pipes to form a closed loop of the whole system. Well-designed, properly connected solar-powered pipelines are crucial to the optimal functioning of the solar system. Solar energy pipe must be heat treatment, cold northern areas need to be laid in the pipe wall with tropical, in order to ensure that users can also be used in the cold winter solar hot water.
Control unit
General domestic solar water heaters need automatic or semi-automatic operation, the control system is essential, the controller is commonly used automatic Sheung Shui, water full of water and show the water temperature and water level, with auxiliary heating solar water heater also leakage protection, anti-dry Features. The market has a mobile phone message control of intelligent solar water heaters, water temperature water level check, fault alarm, start the water, shut down the water, start heating and other functions, to facilitate the user.
Bar fittings suit for 42.4mm and 48.3mm tubes.
Stainless steel bar fittings are available for railing systems. Currently we use three types, including bar end caps, bar connectors and bar holders.
They are also available in exterior (Grade 316 Stainless Steel, Mirror Polished) and interior applications (Grade 304 Stainless Steel, Satin Finish).
