Water can be supplied by opening the water supply tap using solar energy. Tap water passes through the upper and lower water pipes and begins to replenish solar energy. When the water is full, it will automatically stop. When we use water, close the water supply valve and open the water switch or water mixer.
There are three valves in the water supply system of the solar water heater. One is the tap water switching valve, the second is the water injection valve for the solar water heater, and the third is the after water outlet valve. The water is full. When water is to be supplied, the tap water must first be turned on. switch, then open the water supply valve and drain valve. When the water is full, the buzzer will sound an alarm. Normally, the drain and tap water switches can be normally open,so in actual use, only one water supply valve is needed.
Detailed information
Solar water heaters convert solar energy into thermal energy and heat water from low temperature to high temperature to meet the people's needs in life and hot water production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are the main ones, accounting for 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related accessories. The conversion of solar energy into thermal energy mainly relies on heat collecting tubes. The heat collecting tube uses the principle of floating hot waterupward and cold water descending to cause microcirculation of water to achieve the required hot water.
When the vacuum tube water heater absorbs heat, solar radiation passes through the outer tube of the vacuum tube, is absorbed by the heat collecting coating, and then transferred to the water in the tube along the wall of the inner tube. . After the water in the tube absorbs heat, its temperature increases and its density decreases and increases, forming an upward force and forming a thermosyphon system. As the hot water continues to rise and be stored in the upper part of the water storage tank, at the same time the lower temperature water is continuously replenished on the other side of the pipe and so Afterwards, the entire tank is filled. the water rises to a certain temperature.
Flat plate water heaters are generally split type water heaters. The fluid circulates naturallyactually in the heat collecting plate due to the thermal siphon, and the heat radiated by solar radiation on the heat collecting plate is transferred to the water tank timely. The water tank uses a heat exchange (jacket or coil) transfers heat to cold water. Fluid can also flow through the pump to achieve heat transfer.
