The day before yesterday just installed solar energy, today found a vacuum tube completely black, how ahBlack but no water
Yeah, no water. There is a crack in the outer wall of the pipe. Air intake. The pipe is double.The vacuum tube is the core of the solar water heater, his structure is like an elongated thermos bottle container, vacuum between the inner and outer layers.
The inner tube of the solar vacuum tube is broken, and the interlayer of the vacuum tube enters the water. If the outer tube is broken, interlayer inlet, vacuum tubes of white. Either way, you need to change the root canal.
The temperature rise of the hot water in the solar water heater is not related to the outside temperature. When the opening of the kitchen or bath in any one of the taps, the water heater will rely on the natural fall out, the greater the gap, the higher the water pressure. At present, the domestic production of rough pipe enterprises are mainly Connaught, Yuan Yaohui, and other enterprises, the main production of vacuum tube enterprises powerful new materials, Nobel Baoguang heat collection tubes and other enterprises, there are two main types, one is not a water pipe, water pipe is the traditional vacuum tube is a tube water, double vacuum launch and heat pipe in-line launch vacuum tube makes glass tube is not water.
The surface of the inner glass tube is coated with a selective absorption coating by a special process to absorb the solar radiation energy. By sunlight, the photons hit the coating, solar energy into heat energy, water from the outside of the coating absorbs heat, the water temperature increases, the density decreases, the hot water to move up, and more than a significant drop in cold water. Hot water is always on the upper part of the tank.
