A more detailed description of who knows
As we all know, solar energy, as a new energy with bright prospects, is being paid more and more attention. Solar energy water heater as the representative of the rapid development of the green energy industry, but accompanied by disorderly and chaotic state has to pay attention to. The lack of access standards, the enterprise quality problems caused by serious effects of dragons and fishes jumbled together, the solar water heater in China further promotion and popularization, improve the quality standard of solar energy, regulate the development of the industry is imminent.
Three also pay attention to the diameter and length of the vacuum tube, which directly determines the size of the vacuum tube heating surface, the distance between the vacuum tube, the general two tube center distance is about 75mm. It is best to choose the solar power that can produce vacuum tubes. Haier launched the solar industry to enhance the quality Quality Alliance in 2010 04 months 21 days 10:38 April 21st today, "solar energy quality alliance was founded in beijing. The alliance is composed of solar leader Haier launched China, Baoshan, Kim, GE and other domestic and foreign top suppliers, the United China Appliance Association, Chinese Quality Association, China Consumer Association, the state information center, information resources development department jointly established. The alliance aims to provide the best quality products for consumers with the best materials and service team, through the powerful combination of the best raw materials suppliers in the industry and solar manufacturers and distributors. Industry experts said that the current situation in the quality of the industry worrying, Haier move in highlighting its role in the quality of the vane, but will drive the upgrading of the quality of the entire solar industry.
Two is the use of eye observation, the purchase should be carefully observed in the vacuum tube glass coated tube, vacuum tube using the inferior solar energy, it is the blue color coating, good quality coating color uniformity, the film is black, no scratches, no peeling or shedding phenomenon, no glass stones. Supports the glass pipe in the correct place, no loose. Do not choose the red tube
Don't listen to what the solar water heater "three high", "space tube '," "the ordinary vacuum tube is a manufacturer name trick, one touch, feel if the temperature is normal, slightly cooler, which indicates that the vacuum tube for quality product; if feel hot, the vacuum tube quality is not good in it, and at the same time absorbing heat, the effect will be relatively poor in winter;
