The principle of solar water heater introduces the working principle of solar water heater
Solar water heaters are more energy-saving water heater products that are used nowadays. Solar water heaters are usually used in some places where there is sufficient light, and the working principle of solar water heaters when working is what we usually use. Gas water heaters are different, so what is the principle of solar water heaters ? The following decoration home decoration network Xiaobian will bring you the working principle of solar water heaters, hoping to help everyone. Â Â What is the principle of solar water heaters? Solar water heaters convert solar energy into heat and heat water from low to high temperatures to meet the hot water use in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat solar water heaters according to the structure, and vacuum tube solar water heaters, accounting for 95% of the domestic market share. The vacuum tube type domestic solar water heater is composed of a heat collecting tube, a water storage tank and a bracket and the like, and the conversion of solar energy into heat energy mainly depends on the heat collecting tube. The heat collecting tube utilizes the principle that the hot water floats on the cold water to make the water generate micro-circulation to reach the required hot water. Introduction to the working principle of solar water heaters: The flat-panel type water heater is generally a split type water heater. The medium is naturally circulated by the thermosyphon in the heat collecting plate, and the heat of the solar radiation on the heat collecting plate is timely transmitted to the water tank, and the water tank is heat exchanged (jacket or coil). Heat is transferred to cold water. The medium can also transfer heat through the pump cycle. When the vacuum tube type water heater absorbs heat, the solar radiation passes through the outer tube of the vacuum tube, is absorbed by the collector coating film, and is transferred to the water inside the tube along the inner tube wall. After the water in the tube absorbs heat, the temperature rises, the specific gravity decreases and rises, forming an upward power, forming a thermosyphon system. As the hot water continuously moves up and is stored in the upper part of the water storage tank, while the lower temperature water is continuously replenished along the other side of the tube, the whole tank water is raised to a certain temperature. Domestic solar water heaters usually work in a natural circulation with no external power. The vacuum tube solar water heater is a direct insertion structure, and the hot water is powered by gravity. Flat-panel solar water heaters are powered by tap water pressure (called top water). The solar central heating system uses pump circulation. Since the solar water heater has a small heat collecting area, in consideration of heat energy loss, pipeline circulation is generally not used. The flat-panel solar water heater works in the top water mode, and the vacuum tube solar water heater can also implement the top water working mode. The water tank can be jacketed or coiled. The advantage of the top water work is that the water supply pressure is the tap water pressure, which is larger than the natural gravity type pressure, especially when the installation height is not high. The water temperature is high and then low during the use, easy to grasp, the user is easy to adapt, but the tap water is required. Maintain water supply capacity. The solar water heater in the top water working mode is more expensive and higher in price than the gravity water heater. These are the principles of solar water heaters, small series to bring you introduce the entire contents of the working principle of solar water heaters, we believe that after reading this article have a basic understanding of the solar water heater works, if you want to know more decoration advice, please Click to enter the decoration knowledge channel .

A drinking glass is a glass which has been designed to hold a fluid for drinking. There are a number of drinking glass styles, ranging from generic drinking glasses for milk, water, and juice to specialized drinking glasses like champagne glasses. Drinking glasses are part of a large glassware family known as beverageware or Drinkware . They are differentiated from mugs and cups by their glass construction, and the fact that they lack handles. A drinking glass is often sold as part of a set with coordinating glasses in various sizes and shapes.
We offer a diversity of glassware products mainly including many types of Drinkware, Wine Glasses , Glass Vase , Glass Plates/Dishes, Glass Candle Holder, Storage Jar , wood product, ceramic, Rattan Wrapped Glass, and lots of other popular glass products on the market. With numerous glassware available on our site in different color, shape, process and design, many of them can be customized.
