Standard lag time constraints in the future development of solar water heaters
[REVIEW] solar water heater energy efficiency standards is an important reason for the absence of related subsidies, and \"energy efficiency of domestic s and energy efficiency level limit value\" standard to be submitted for review at the end of October. In fact, in recent times, attention to relevant departments in the country, China\\ s solar water heater standards are rolled out, only because after a long period of non-industry standard laws of the state, the continuous introduction of several standard has not yet play a significant effect.
Solar water heater energy efficiency standards is an important reason for the absence of relevant subsidies, and \"domestic solar hot water system efficiency limit value and energy efficiency rating\" standard to be submitted for review at the end of October. In fact, in recent times, attention to relevant departments in the country, China\\ s solar water heater standards are rolled out, only because after a long period of non-industry standard laws of the state, the continuous introduction of several standard has not yet play a significant effect. Standard lag for the impact of the development of solar water heater for some time in the future will continue to exist.
Standards into the fast lane
Chinese Solar Energy Society, said Luo Zhentao Industry Committee, beginning in 2009, the state authorities to speed up the solar water heater standards work.
January 1 this year, \"domestic solar water heating system controller\" officially promulgated national standards. Also in this year, \"solar hot water system with the rubber seal\" is officially implemented.
Recently, China\\ s solar thermal industry alliance Secretary-General Huozhi Chen said, after a year of continued promotion of solar water heater energy efficiency standards will be the end of October to complete all the work, will the national energy efficiency labeling management center trial.
In addition, the \"solar air collector technical conditions\", \"solar air collector thermal performance test method\", \"split double-loop solar domestic hot water system technical conditions\", \"split double-loop solar domestic hot water system performance test method \"four solar thermal technology has been completed using the national standards seek stage, industry sources, the implementation of these standards will raise the threshold for market access of solar water heaters, regulate the industry.
Although the formulation and implementation of the standards are in full swing them, but because of \"debt\" too much, now, to regulate this industry standard is still too little.
Regulate the development of imminent
At present, China\\ s solar water heater to maintain the total accounted for 76% of the world\\ s total, but the solar water heater overall consumer satisfaction, only 53.9%. Nearly 6,000 in the business, the real scale with R & D capabilities and production of business less than 20. It is not difficult to see, China is the production of solar water heaters use a big country, not the technical power, which is one of the main crux of the problem: the lack of production standards.
For a long time, it was believed that the solar water heater is a new industry, carbon industries, need support, but not to regulate its rapid introduction of the standard, which leads to long-term no criteria to guide the industry, and even some of the safety standards at all.
China\\ s solar water heater and did not implement the production license system, although the state has issued a relevant product quality standards, but all the sale of solar water heaters do not need a separate test, as long as the enterprises in accordance with national standards to produce, own commitment to protect the product quality can be . Lack of standards, cohabitation has seriously affected the business of solar water heaters in China to further promote and popularize.
In coastal areas, poor quality of solar water heater is wrapped in heavy rain storm to bring down, resulting in a number of personnel and property damage from the accident. The crux of this issue is not related to the installation of solar water heater standard, resulting in the installation of materials installed to use the quality tests, corrosion resistance is poor, installation design, unreasonable, or even cut corners when installing, so frequent accidents.
Widely used in China for the , vacuum tube is the product of the \"heart.\" But, the quality of vacuum tube production enterprises, specifications vary from 1.5 meters to 2.3 meters. Since the state has not issued the relevant mandatory standards to regulate the length of the tube, resulting in increased maintenance costs of consumers, even in the case of business failures was told can not be repaired.
