Solar water heater standard is expected to launch the second half of 2011
By the National Development and Reform Commission, China National Institute of Standardization, the National Standardization Technical Committee of solar led the drafting of the first mandatory national standard – \"home efficiency of limited value and energy efficiency rating\" (hereinafter referred to as \"energy efficiency rating\") has into real operational phase, sent to the national energy efficiency labeling management center validation, and is expected to launch in the second half of 2011.
By the National Development and Reform Commission, China National Institute of Standardization, the National Standardization Technical Committee of solar led the drafting of the first mandatory national standard – \"home solar hot water system efficiency of limited value and energy efficiency rating\" (hereinafter referred to as \"energy efficiency rating\") has into real operational phase, sent to the national energy efficiency labeling management center validation, and is expected to launch in the second half of 2011.
It is understood that the \"energy efficiency rating\" is the development of solar energy companies in the 81 trials with a variety of products formed on the basis of the study, and based on actual research and product usage and product standards have been classified as compact, separate-and bored with indirect drying-type three species, and each product is divided into three energy efficiency rating.
For the previous five to three criteria, participation in standards development, experts said, because \" system technology,\" this revision to improve the performance of solar products, and energy efficiency is identified as a basis, if divided into five, will lead two of the performance index is very close, increase the difficulty of detection, so the energy efficiency of solar water heaters will be divided into three, one of the most energy efficient products.
It should be noted that the use of solar water heater itself is a work of natural sunlight as energy, there is no basis for energy-saving considerations. This time the \"energy efficiency rating\" based on the formulation of daily heat gain and heat loss of two technical indicators to determine the energy efficiency of solar water heater product level, even the three energy-efficient products are also cleaning products
