Description
Technical field
The invention belongs to household electrical appliance efficiency and evaluate field, particularly relate to a kind of air-conditioning on-line operation energy efficiency monitoring and evaluation system and method.
Background technology
Along with China's sustain economic high speed development and national income improve constantly, the use of household electronic products, value volume and range of product are all increase fast and gesture universal rapidly, power consumption total amount of its generation also with every year on average 10% speed increase.But China's Energy situation allows of no optimist, strengthening energy conservation priority becomes national energy strategy important option.For this reason, State Council has printed and distributed " " 12 " energy-conserving and environment-protective industrial development planning " on June 16th, 2012, emphasize that energy-conserving and environment-protective industry is that country accelerates one of 7 emerging strategic industries cultivated and develop, and emphasis claims, quickening household appliances are as Based Intelligent Control power-saving technology and standby energy consumption technical research progresses such as air-conditioning, washing machine, refrigerator, television set, water heaters.
The measure that Oriented by Enterprises Energy-saving reduces discharging carries out Energy Labeling certification to product.As for air-conditioning products, 2004, National Development and Reform Committee, National Standards Commission issue and implement " room air conditioner energy efficiency market and energy efficiency grade " (GB12021.3-2004 substitutes GB12021.3-2000), " unit type air conditioner energy efficiency market and energy efficiency grade " (GB19576) and " handpiece Water Chilling Units energy efficiency market and energy efficiency grade " three national standards.Air-conditioning is divided into 1 to 5 grades according to Energy Efficiency Ratio by regulation, and 1 grade the most energy-conservation, and 5 grades of efficiencies are minimum, do not allow list marketing lower than the product of 5 grades, and Air-conditioning Enterprise needs to stick on Energy Labeling on product, informs its efficiency hierarchical level of consumer.
Although Energy Labeling approval procedure has guided product to energy-conservation, reduction of discharging future development, existing efficiency evaluation and management have had following point:
1) because efficiency grade entrusts third party or testing result demarcation voluntarily according to enterprise, be a kind of behavior of personal control, therefore, cause some household appliances enterprises to be that the event of gaining energy-conservation subsidy empty mark efficiency grade by cheating is reported in media again and again.Only issuing the household appliances sampling results such as washing machine, refrigerator and television sets in 2012 with nearest Shanghai City matter office, being on the list with regard to there being numerous once rather well-known brand.Display in its report, in 17 batches of washing machines, 5 batches defective.And in these underproof products, the home brands such as once far-famed power, Konka, duckling, also have the internationally renowned brands such as Panasonic, be all on the list because defective item relates to washing (-)off properties, power consumption and efficiency grade.Such as in the inspection of refrigerator, a station symbol is called the power board BCD-165MX1 model freezer compartment of refrigerator of 1 grade of efficiency grade, and test does not reach the minimum limit value of subzero 18 DEG C of national Specification unexpectedly.In fact, numerous washing machine, refrigerator efficiency grade already empty mark are serious, and 3 grades, 4 grades efficiency void are designated as 2 grades, and 2 grades of efficiency void are designated as 1 grade, even also occur that efficiency threshold does not also reach but void and is designated as 1 grade of efficiency product.
