Himfr.com Reports Solar Water Heater Energy Efficiency Standards Have Been Questioned
A consumer to buy a an energy-efficient solar water heaters
, resulting in less than three years, with the bad. "You say that such a energy-efficient solar energy in the end it is good or bad?" The consumer asked the reporter. A solar energy enterprises on condition of anonymity told this reporter that engineers currently in a number of solar water heater technology, spare parts, hot water and other infrastructure projects have not developed standards and improve on the rush to promote the development of solar energy efficiency standards, a bit act with undue haste.Beijing New Energy and Renewable Energy Association Vice Chairman Luo Yun-chun told reporters that now that a solar water heater energy efficiency standards is difficult, even if drawn up will face difficulty in enforcement. Solar energy better than air conditioners, refrigerators and other appliances mature, their poor foundation for development, many of the basic conditions do not improve, and do not have the product energy efficiency standards to promote soil.
A solar energy company sources, the relevant bodies in this standard-setting process, taking into consideration the standard of health is not an industrial sustainable development, but the interests of all parties can get how much. Some agencies in order to develop this standard ground head, to want to participate in the enterprise to set threshold standards must be by these institutions and organizations to participate in a number of exhibitions, forums, disguised charges. Virtually increase the business costs and expenses.
LUO Yun-jun told reporters that at present the field of solar water heaters need to develop and improve the standards of many, especially when it comes to product performance, quality, and materials and other basic components of standards, there is also imperfect place. Lighting such as solar water heaters, heat-absorbing area, the definition of terms such as the reflection coefficient is not clear. The current vacuum tube water heaters, heating area in the end how the calculation, we should not be deducted on glass aperture. Another example of solar water tank, frame and other key components of the material, thickness and so there is no uniform requirement.
"We must engage solar energy efficiency standards, now the area of how to calculate heating and unity are not clear, how to count the value of energy efficiency? National Standards emphasize that the authority and scientific, to the time standards were introduced to explain the unknown, that would be trouble joke. "LUO Yun-jun said.
Experts say learn from the relatively mature standard-setting system for home appliances of view, are the first complete standards-based products, and then formulating the overall performance of the standard product, so that from low to high, from basic to the performance of a steady push. At present, the development of solar water heaters in China in just 10 years time, typical of grass-roots industry, after the government and relevant industry associations based standards for product development work has been relatively lagging behind. Right now, for the standard-setting in this area, should accelerate the improvement of the basic products before specification and to promote market development of this product and order.
National Solar Water Heater Quality Supervision, Inspection (Wuhan) The Center Chief Engineer Zhang Xiaoli told our reporter, solar water heater energy efficiency standards by industry associations are not the lead organization, but directly from the Development and Reform Commission and the Commission jointly to promote the national standard is currently the standard has been held over two seminars, the test of 61 enterprise's product data, energy efficiency standards for an initial period of five criteria.
Zhang Xiaoli with particular emphasis on solar energy is different from the traditional consumer electronics, and appliance energy efficiency is not a concept compared to solar energy are clean energy, energy consumption does not exist, even five energy-efficient products, but also energy-saving products.
Solar industry observers, Zhicheng Wang Chengying Smart, chairman of the view that the product energy efficiency standards does not matter sooner or later, there is no better than to promote the standardization of product energy efficiency is one of the industry's development direction.
