China's northern winter heating with a large number of coal combustion, aggravated air pollution. So, is there any clean renewable energy for winter heating? What about solar heating? Can it be promoted on a large scale? Solar heating is applied less than one in a thousand in the countrySolar heatin

After two years of declining sales, the Polish solar collector market showed an upward trend in the first half of 2018. According to the polish association of heating equipment manufacturers and importers (SPIUG), sales of collectors increased by more than 50% in the first half of 2018, as shown in the figure below. Much of the industry's growth was due to the fact that many companies had won open tender contracts in the previous year.

Indirect solar hot water system, the heat transfer cycle system needs to use the heat transfer medium, of the heat transfer system corrosion and prevention as many flat solar manufacturers concerned about the problem. This paper will analyze the causes of corrosion from many aspects and put forward preventive measures.

Plate solar collector (hereinafter referred to as the "flat-plate collector") to receive the most solar radiation, the most mature technology, low cost and no need to trace the characteristics of the dispersion of strong, fit the solar energy can flow density is low and unstable characteristics, is the most warm in a large number of low human can consume one of the most effective device, its solid slab structure is easy to combine with architecture, as solar heat utilization technology and hardware support.

Taking "solar air source coupling hot water system" as an example, the annual energy-saving rate of solar energy is analyzed and calculated in detail. From the perspective of the calculation process and calculation basis, this calculation method is more scientific and reliable, and has important reference significance for the analysis and calculation of energy saving and emission reduction of solar thermal application system.

2018 China solar energy industry and economic development (Beijing) BBS and the first "China solar energy excellent parts" award ceremony was grandly held in Beijing.
