The main advantages of solar single-series series-parallel system are easy installation, natural circulation of the system, stable and efficient heat collecting effect, and the number of solar single-units can be increased when the unit staff increases the amount of hot water, but the following points should be noted for the single-machine project.

AbstractFor a long time, the solar water heater industry has entered a low threshold, and counterfeit and shoddy products have become rampant. At present, there are hundreds of brands of solar water heaters on the market, which are dazzling and can't distinguish between good and bad.

1 IntroductionSince the heat output capability of solar water heaters is greatly affected by weather conditions such as sunshine, environment and temperature, in order to obtain hot water stably, domestic solar water heaters are usually equipped with auxiliary heat sources, and auxiliary electric he

Compared with active building energy-saving design, passive building energy-saving mode has low investment cost and low technical requirements. It is an efficient, low-consumption and low-pollution building design, and is one of the main ways for the future development of architectural design.

At present, solar energy has a bad reputation in some markets, which has affected the development of enterprises and the entire industry. The reason is nothing more than the internal and external causes. Combine what I have seen and heard, and do the following analysis for reference.

Taking the solar energy air source coupled hot water system as a sub-project of the Guangxi Environmental Protection Department's dilapidated housing reform project, the annual energy saving rate of solar energy was analyzed and calculated in detail. From the calculation process and calculation basi
