Energy efficiency

 

For the establishment and improvement of industry standards system

Solar water heaters

Industry began to take action. It is understood that within the next few years, solar energy

Water heater

Industry will be issued 16 standards, energy efficiency standards for solar water heater is one of the first on the agenda, and by the widespread concern outside the industry.

2009 4 22, Yangzhou Lida Solar Japan Co., Ltd. (hereinafter referred to as “Japanese Leader”) was held in Beijing, “Japan-profit energy-efficient solar Seminar.” Described in detail at the meeting on the development of corporate profit efficiency standards?? Q321001FTA4-2008 “domestic solar water heating systems limit the value of energy efficiency and energy efficiency levels,” and the entire contents of the entire process of development. The experts believe that Japan’s corporate profit energy efficiency standards for the formulation of national standards with the first meaning. Solar thermal utilization in China Industry Alliance Executive Chairman Luo Zhentao revealed that the solar water heater efficiency standards in the developed countries to work is well underway to start the General Assembly will be held in May this year. Energy efficiency.

Standard-setting business first

“Japanese Leader to develop enterprise energy efficiency standards to meet the requirements for the development of solar water heater industry. Although the use of solar water heater is clean

Energy

, But over the years because of energy efficiency is no mandatory requirement, coupled with low brand concentration, some low-energy efficient products is still popular in the market, while the introduction of energy efficiency standards to limit and eliminate inefficient products, and promote the development of solar water heater industry. “Japanese Leader, Chairman Wang Hui Yu said. According to reports, a conversion rate of solar energy water heater, must do three aspects: first, endothermic endothermic nature of the system, and second, thermal system insulation of Paul, 3 is the thermal conductivity of the system, each link should not be overlooked. and

Home Appliances

Product difference is that a solar water heater does not consume energy, its energy efficiency level is the level of the main level of thermal performance of the system. Energy efficiency.

It is understood that profit making companies on energy efficiency standards mainly GBT19141 “Household solar water heating systems technology” and HJT363-2007 “the technical requirements for environmental labeling products for domestic solar water heating system” based on two criteria and reference relevant provisions of the foreign. According to Chief Engineer Zhao on profit group introduced the implementation of the standard range of hot water storage tank volume of 0.6m3 of solar water heating systems for home the following, and GBT19141 “Household solar water heating systems technology” provides the same scope, and specific product categories by reference to the GBT18708-2002 “Thermal performance of domestic solar hot water system test method” requirement, the product is divided into compact, discrete and indirect 3. The business solar water heater energy efficiency standards will be divided into five levels, energy efficiency grading basis for the domestic hot water systems on unit area of a useful outline of light minimum and average thermal heat loss factor of the maximum (see Table 1). Among them, the Energy Efficiency 5 for the limited value of energy efficiency, related numerical and GBT19141 “Household solar water heating systems technology” provisions. Energy efficiency.

Intense national standards

Experts believe that the Japanese Leader to develop enterprise energy efficiency standards is important. “Japanese Leader to develop energy efficiency standards under the effort, and energy efficiency grade gradient more realistic, reflecting the solar water heater industry level, while the enterprise first step to develop energy efficiency standards in line with industry development track.” National Solar Water Heater Quality Supervision and Inspection Center (Beijing), deputy director of Renhe Tao said. “Enterprises are able to walk in front of a good thing, for the formulation of national standards to provide a reference.” Solar water heater National Quality Supervision and Inspection Center (Wuhan) Room in chief engineer said. However, He Tao believes that the formulation of national standards, more factors to consider, “This standard is formulated in accordance with the enterprise itself, the formulation of national standards is more complex, more comprehensive, if we take into account different collector solar water heater The type of. ” I know that the solar water heaters in China is dominated by all-glass vacuum tube products, in addition, type and plate type heat pipe products account for a certain percentage. Energy efficiency.

It is understood that the national energy efficiency standards for solar water heater is approved in December 2008 set the standard name of “domestic solar water heating system thermal efficiency limit the value and efficiency rating.”

 

 

In refrigerators, air conditioners, washing machines, TVs and other products for energy efficiency standards promulgated and implemented the same time, improve its energy efficiency level is also in the pipeline. However, the market, energy-saving products were praised in the situation still exists, the experts interviewed pointed out that upgrading the level of energy efficiency appliances, not only the efforts of enterprises and consumers energy-saving awareness, also needs a strong government incentives promotion. Energy efficiency.

Appliance energy efficiency standards enter the full upgrade phase

2005 3 1st, China’s domestic refrigerators and air conditioning energy efficiency labeling system is in operation. In order to give the market a transition period, the relevant state departments to permit March 1, 2005 have been imported, produced no identification refrigerator and air conditioning sales to 1 September. Then, led by the China Institute of Standardization developed the “color television receivers limit the value of energy efficiency and evaluating values of energy efficiency” standards are promulgated in November 2005 and on March 1, 2006 began formal implementation. It is understood that the implementation of energy efficiency in China’s household electrical appliances will also be identified from the current refrigerators, air conditioners, washing machines, color TV extended to gas water heaters, drinking fountains and other high prevalence of small appliances.

CNIS director of energy efficiency labeling, energy infrastructure and management of the National Standardization Technical Committee of the Secretary-General Li Xian love that energy efficiency standards in China have entered a stage of a comprehensive upgrade. The logo, in addition to the expansion of product range, more importantly, changes in technical content. New system, the revised part of the energy efficiency standards for energy efficiency in the original assessment of the value of limited value and energy efficiency but also provides energy efficiency rating and advanced energy efficiency and other indicators of limited value. National Energy Foundation and Management Technical Committee have been the first appliance efficiency standards on a comprehensive amendment, some of which standards have been revised for the second time. Energy efficiency.

CNIS, director of energy efficiency labeling management Wangruo Hong said, in September to carry out the refrigerator, air conditioner energy efficiency label inspection is almost over, from the sampling results, the overall energy efficiency level of air conditioning is increasing, level 2 products increased, while the initial estimate five air conditioning products for more than 80% pass rate. But Wang Hong also said that at present China’s energy efficiency level of air conditioning products, and in 2009 will amend the “room air conditioner energy efficiency rating limit value and energy efficiency,” there is a considerable gap between the provisions. According to report, the current air conditioning products on the market is still dominated more by 5, which is the average of a refrigerator, two very different levels of energy efficiency. That is now our air conditioning products, the general level of energy efficiency that is not energy efficient.

But Wang Hong also pointed out that the current situation on Technology is not the problem, the most fundamental reason lies in the cost of the above, we all know, raise the level of energy efficiency one of the ways is to increase the area of heat exchanger and air conditioning products, which will increase copper, aluminum and other raw materials, use of the product, but now the price of raw materials is rising sharply, manufacturers have been formed to pressure.

An air conditioning company official said: “production of energy-saving air-conditioning must be replaced by ordinary copper grooved copper tube, compressors have to replace a highly efficient, generally at least to these energy-saving production costs increased by 300 yuan. lowered prices in home appliances, the current rising prices of raw materials, the pressure of each enterprise are very large, so even though strongly amortization, a significant portion of the additional costs, still can only be passed on to consumers. ” Energy efficiency.

Government needs to develop effective incentive mechanism

According to “People’s Daily” reported that the Spanish Government is implementing a plan to promote energy-saving appliances. To encourage the public to buy energy-saving appliances, plans to require the purchase of a replacement A-level energy-saving products and old products, to give consumers some concessions. Discount rate determined by the autonomous region, generally between 75-80 euros, about equal to the price of a home appliances 15% -20% bonus by the government subsidies, replacing the uniform down Jiujia Dian recycling. In addition, in accordance with the new rules, new housing must be equipped with the appliances are to achieve A-class energy efficient products. The Government will provide funds to promote energy-saving appliances plans to invest over 200 million euros. It is understood that in the United States, the Government will through financial.incentives to encourage manufacturers and users to achieve higher energy efficiency standards, to purchase “Energy Star” energy-saving product certification can be obtained from the public funds to finance the return of the exemption from consumption tax and other benefits.

Marketplace will see all of the appliances will have a “energy efficiency label affixed.” Found that the current energy efficiency labeling on these figures are marked by the manufacturer directly, as the market has not yet led to the formation of an effective supervision system identifies home appliances energy efficiency, “Water” big, formed a misleading consumers. A person engaged in home appliance sales told reporters: Now manufacturers, whether or not the highest energy efficiency rating, but they like to mark the highest energy efficiency rating, so the energy efficiency label is now the consumer has no reference value.

In fact, the subject of energy efficiency issues in the trade of virtual identity is not secret. “What grade are marked on their own, said the operator, mainly lack of supervision caused the market.” Appliance sales reflect this. Last year, several countries have also conducted sampling, the results from the sampling of view, the energy consumption of a regional virtual appliance stores reached 50% of the standard problem, which identifies the energy efficiency of small businesses almost 100% of the virtual standard, while some large There is also the phenomenon of virtual brand standard.
What causes
household electrical appliance enterprises are willing to do energy-efficiency labeling of Deficiency?

“Hidden rules” of virtual exposure to energy efficiency standard issue

Since the national energy efficiency are not the subject of false identification to be checked, then the question is how the virtual standard found it? Reporter with a
Refrigerator
A corporate R & D personnel interview that: At present, refrigerator standard problem of virtual enterprises are also common. At the same time, the researchers also described a “hidden rules” are exposed fundamental problems of energy efficiency virtual object.

Said, according to the R & D staff: At present, many companies have introduced information on consumption of 0.35 degrees below the refrigerator, some enterprises have even reached the Japanese consumption of 0.27 degrees, 0.29 degrees, this propaganda is false propaganda. This R & D personnel reveals that, in the refrigerator industry, there is a “hidden rules”: any of a company introduced a super-efficient refrigerators, so the super-efficient refrigerators must be other manufacturers to learn from. Other companies usually buy a rival claim of the low power of the refrigerator, first test, and then dissected to see opponent’s manufacturing process, using what technology. This is a “hidden rules” to allow this research found that the market is claimed on their power companies 0.27 degrees, 0.29 degrees of the refrigerator in line with state regulations out of the laboratory test values were 0.38 degrees and 0.41 degrees far beyond the national scope of the provisions of the energy efficiency of floating.

“This is the only lab results, if placed in regular environments, power consumption at least more than 0.5 units of electricity, not just virtual target problem and it is arbitrary standard.” This R & D personnel stressed to reporters. Another reporter also made a large domestic refrigerator business related to personnel, but the other did not give a clear answer.

Enterprises do not lack faith market supervision

Standard for energy efficiency labeling of virtual enterprises concerned, the industry expert analysis: household appliances put a lot of energy-efficiency labeling implies the trap that some companies with “Every potter praises hit” type of way to publicize the lack of self-exaggerating the integrity of the practice, so in urgent need of relevant norms.

‘s Investigation found that the lack of market supervision, many of energy-efficient sales channel identification stickers are to be posted up sales, and sales of certain brands of drawer or even a large number of different energy-efficiency labeling stickers After the prototype refrigerator can put their own paste, due to its own sales staff do not know what the refrigerator is level of energy efficiency, it usually will be the highest energy efficiency labeling a paste on the refrigerator, this approach is in fact false identification enterprises lack faith, consumer fraud practices.

“Are products that consumers choose energy efficiency an important factor in the refrigerator, so some manufacturers virtual standard of energy efficiency will undoubtedly mislead consumers identify the purpose of selling products, whether you look at what is now the mall refrigerator dare Paste the highest energy efficiency rating label. “a refrigerator brand sales representative angrily.

It is reported that the energy efficiency of appliances for the construction of national identity is a saving society to a proposed policy, but a few bad faith business practices in real terms is misleading, fraudulent behavior. Ningbo Yongcheng a household electrical appliance industry veteran told reporters, a number of household electrical appliances “grade virtual standard”, this profiteering, “especially in the rural market, the phenomenon of virtual standard more focused.” Therefore, the energy efficiency label urgent national authorities regulate.
