24 hour operation.
The solar circulation pump can operate 24 hours a day. Most solar circulation pumps need to operate 24 hours a day and require a dedicated dual outlet to provide electricity: turn off the hot water under the faucet connection line to access the sink area. The closer the faucet is to the elbow, the faster hot water will flow from the pump circuit. Water from this pipe connection will return to the cold water pipe and then recirculate to the hot water tank. It is important that all hot water circulation pump circuits are insulated with foam insulated pipes.
There are many brands of solar water heaters, such as Huangming, Sanle, Temple, Tsinghua Sunshine, Aucma, etc. The recommendations are as follows:
1, Huangming: Huangming Solar Energy Co., Ltd. (hereinafter referred to as “Huangming Solar Energy Co., Ltd. "), as a leader in the global solar energy industry, promotes a collector area of 3 million square meters per year, which is equivalent to the entire European Union and twice the area of North America. The business mainly includes: solar water heaters, high temperature solar thermal power generation, solar air conditioning, seawater desalination, etc.
2. Sanle: Shandong Sanle Solar Energy Co., Ltd. was founded in 1987, with Shandong Academy of Sciences as technical support. It is a high-tech joint stock enterprise located in Jinan City. become a national research, development and production company. An integrated, large-scale, specialized solar power generation company. Currently, he is the vice president of the China Solar Energy Industry Alliance and the president of the Shandong Solar Energy Society.
3. Temple: Temple began operations in 1989 and is committed to becoming a globally trusted, comprehensive provider of new energy services. In more than 20 years of development, it has always been at the forefront of industrial development, from inventing the first round solar water tank and redefining the appearance of solar water heaters to the first development of the Ф 58, which today represents more than 80% of the market. Vacuum tubes, etc.
4. Tsinghua Sunshine: Beijing Tsinghua Sunshine Energy takes solar energy utilization technology as the core and integrates product research and development, manufacturing, engineering design and marketing, and engages in the promotion and application of clean energy. Tsinghua Sunshine Company built the world's first automated collector tube production line and the largest full vacuum collector tube production base.glass producer in the world, with an annual production capacity of 12 million collector tubes and 300,000 water heaters.
5. Aucma: Aucma adheres to the strategic goal of becoming the world's most reliable refrigeration equipment supplier and "refrigeration expert", constantly promotes technological innovation, and has formed a core business of freezers, refrigerators and of commercial products. cold chain products. The main business focuses on ultra-low temperature equipment, electric bicycles, washing machines, household appliances and vending machines as the development activity, and new energy electric tool carts and household appliances new energy as a future activity.
Detailed information:
Solar water heater selection method:
1. Parmi thermal performance indicators, the higher the “average daily efficiency” the better, and the lower the “average heat loss coefficient” the better.
2. The key part of the domestic solar water heater is the all-glass evacuated solar collector tube (called vacuum tube). The quality of the vacuum tube directly affects the performance of the whole house. solar water heater.
3. The support design of domestic solar water heaters should be reasonable and should have sufficient strength, rigidity and corrosion resistance to ensure sufficient long-term carrying capacity. When purchasing a home solar water heater, you should be careful not to focus only on the appearance of the bracket.
4. Reflectors for domestic solar water heaters are very important and come in various shapes including flat reflectors, curved reflectors, embossed aluminum, etc.
5. It is very important to choose the insulation layer of domestic solar water heaters. Polyurethane foam is generally used, but polyurethane is divided into several grades and their quality varies greatly.
