In in September this year, the National Standardization Management Committee announced the 10 national standards formulated and revised project plan, GB12021.2-2008 the household refrigerator power consumption limit value and energy efficiency rating "(hereinafter referred to as the refrigerator energy efficiency standards) amendment items among them. This means that the 4 years of the refrigerator energy efficiency standards will be revised. At present, the refrigerator safety and performance standards are also revised, and has been approved.

　　Energy efficiency standards years or will come up with a draft of the draft

　　The implementation of the energy saving products for the implementation of the energy efficiency for the Chinese home appliance industry has played a tremendous role in promoting the energy efficiency level of mainstream home appliances and 3 years ago have a greater upgrade. Such as the current provisions of the refrigerator energy efficiency standards, energy-efficient products refrigerator energy efficiency index is less than 40%, and other types of products of energy efficiency index is not greater than 50%. But it is understood that the market now 90% of the refrigerator are 1 energy efficiency products. This shows that the current energy efficiency standards for refrigerators is not consistent with the current situation of the development of the industries and products, the role of norms in the industry is not obvious, so the revision of the refrigerator energy efficiency standards will be put on the agenda. "For this standard amendment, the industry has been discussed several times." Cheng Jianhong, a researcher at the China Institute for standardization research, said the hope can be the fastest pace to complete the work, and strive to come up with the draft at the end of 2013.

　　Safety standards have two changes

　　The special requirements of safety standards GB4706.13-201X "household and similar electrical appliances Safety of refrigeration equipment, ice cream machine and ice making machine since July 2012 in Qingdao held a kick-off meeting, after a series of amendments, has formed the draft for approval. New safety standards level using the latest version of the international standard, the change is mainly reflected in two aspects: is increased in the standard transcritical refrigeration system of the special requirements; the second is aimed at many of the products on the market in order to beautiful by the phenomenon of glass panel increases the impact test of glass panel, because glass fragmentation will cause a certain impact on personal safety, so standard requirements after the test panel cracked into pieces or with sufficient mechanical strength.

　　Performance criteria will be re submitted for approval

　　Current GB/T8059.2-1995 refrigerator performance standards "household refrigerating appliances refrigerator freezer" formulated in the early 1990s, after more than ten years of development, the original standard has not adapted to the current situation of industrial development. The new national standard to pay more attention to the actual power consumption level and comprehensive performance of the refrigerator product. China Household Electrical Appliances Research Institute of large home appliances business minister Mario Zanin told reporters that the standard has been in the approval stage, but due to IEC62552 the household refrigeration equipment, characteristics and test methods. "The revision is nearing completion, is expected to 2013 will be introduced at the end of the final draft, so grass group will be revised draft for approval, and again submitted to the relevant departments for approval.

　　Energy efficiency testing method deposit disputes

　　According to experts, at present for the refrigerator consumption power test method the main revised contents include: test conditions from 25 DEG C to under 16 and 32 degrees Celsius respectively and calculate the weighted annual electricity consumption; freezing chamber is no longer placed payload packet. Instead, the copper cylinder thermocouple to measure the temperature of the room, the indoor temperature is the average of all copper cylinder thermocouple temperature; the temperature and power to test stability judgment; no frost refrigerator power consumption by stable operation of the power consumption and the frost power consumption during the composition of added value; increase the loading test power consumption; increase the calculation of auxiliary power consumption of the device.

　　Cai Ning said that the new test method of power consumption calculation in more detail, especially of air-cooled refrigerator, to avoid the current standards may exist in the power cycle without defrosting, the measured power consumption closer to the real power consumption. But the problem is that the testing period is too long and the cost is increasing. China Household Electrical Appliances Research Institute of testing methods for the new power consumption test methods and the existing GB/T8059 standards of comparison, the new test method of power consumption will increase by about 20%; better overall performance of the refrigerator, in case of thermostat is not regulated, loading in the process of temperature rise time short and stable operation can recovery to the load of temperature; and to the relatively poor performance of the refrigerator, in the process of loading, temperature rise for a long time, generally after the loading temperature than before loading.

　　In addition, the current controversy in the energy efficiency detection method, mainly in a kind of called "switch door detection" test. According to the introduction, this experiment from the new IEC standard load test. The load test is the process of opening the refrigerator door, the load of the load, the change of the power consumption and the process of the switch door.. In the IEC standard, this is an optional test. And China's refrigerator energy efficiency standards to increase the "opening and closing test" and the different and need to repeatedly switch doors, to model the user's actual usage, so as to make the test data more close to the user actual use of the refrigerator energy consumption. But many enterprises worry that in the actual operation process, because of the measurement tools, test sites, testing methods, etc., resulting in a certain error. There may be a large error between the product test results and the marking value in the late quality spot checks..

　　It is understood that the discussion of the test method is not yet come to the final conclusion, the specific energy efficiency rating and energy efficiency index of the revised direction is not clear.
