2011 年 6 月 1 日, basic parts of CO2 heat pump water heater standard –GB/T26181-2010 ‘household and similar refrigerant heat pump water heater with a fully CO2 engine closed – compressor ‘will be implemented. ‘At present the Chinese market, using the water heater pump CO2 refrigerant heat is not removed, these are the basic elements – the compressor is still under development, but it does not prevent not the development of standards for ‘participating in normative Shanghai Hitachi Minister pump Promotion Office Appliance Co., music Hongshenghuo told reporters before the development of standards in this area relatively promoting products on the market will play a good role.
Reporter noted that the development of standards compressor and water heat pump heater caused all business concerns, Xi’an Qing Refrigeration Equipment Co., Ltd, Shanghai Hitachi Electrical Appliances Co ., Ltd., Guangdong Meizhi Refrigeration Equipment Co., Ltd., Guangdong Wan and the new air conditioners Electric Co., Ltd., Xi’an Daikin Qing’an Compressor Co., Ltd., Daikin Electrical Equipment (Suzhou) Co., Ltd., Shanghai Mitsubishi Mitsubishi Electric Appliance Co., Ltd., Panasonic Wanbao (Guangzhou) Compressor Co., Ltd. and Zhuhai Lingda Compressor Co., Ltd. and so participate.
Performance requirements is the key
‘GB/T26181-2010 detailed list of motors for household and similar CO2 refrigerant heat pump water heater uses heat with fully enclosed – term compressor and definitions, product classification, technical requirements, test methods and marking, packaging, transportation asumitomo coal crushersnd storage requirements, the most important part is the performance requirements of the product, including cooling capacity and coefficient of performance (COP), the input power and operating current, noise, vibration, machine and the residual moisture of impurities and other internal indicators Machine. ‘Guangdong million and the new engineer Huang Qing Johnson Electric Co. said.
Reporters in GB/T26181-2010 ‘Household and similar CO2 refrigerant heat pump water heater with a fully enclosed motor – compressor ‘to see the project for approval, a standard compressor capacity and the coefficient of cooling performance (COP) requirements, testing methods where necessary, the cooling capacity measured shall not be less than 95% of its nominal value, the measured coefficient of performance (COP) shall be at least 95% of its nominal value, and should not be less than in Table 1, the limits specified in Table 2. Secondly, the standard for regulations on noise is when the compressor is running, there should be no noise. When needed by the standard test method, various types of compressors measure (weighted) noise sound power must not exceed the limits specified in Tables 3-5, which measure the speed of the compressor rated speed corresponding noise must not exceed the value of the nominal value of the compressor noise, and the nominal value of noise to comply with laws and regulations and standards. Standard also provides input power and operating current must not exceed 110% of the nominal value.
In addition, when detecting vibration of the compressor, according to standard methods, the compressor rotor at each point of the predetermined maximum value of the measuring cup (setpoint for compressor vibration acceleration variable speed measurement test corresponding speed) shall not exceed the limits given in Table 6, the scroll compressor must not exceed the limits given in Table 7, piston compressor must not exceed the limits shown in Table 8. standard on all residual moisture content and impurity content also makes all internal needs, the limits described in Table 9 and Tacone crusher franceble 10. Additional technical requirements
The standard includes: a compressor should be completed not less than atmospheric pressure nitrogen sealed or dry air (dew point temperature -35 ℃ or less), you can also take to other measures to effectively sealed to prevent moisture and other airborne contaminants; painted surfaces of the compressor casing should be uniform and should not be tainted paint, scratches and rust and other defects; in the accelerated aging test, the cooling capacity and coefficient of performance (COP) of the reduction shall not exceed 5% of the initial measured value, the noise should not exceed the value of the initial measured value of 3 dB (A).
Entry requirements based on national conditions
Reporters learned that there is no CO2 heat pump water heater business promotion refrigerant heat water heater pump in the Chinese market, this product is only in foreign markets exist.
