This document applies to hermetic motor-compressors for room air conditioners, which use the refrigerants R22, R410A, R32, R290 (hereinafter referred to as compressors, including rotor compressors and scroll compressors). The similar compressor, which use other types of refrigerants, can make reference to this standard. 2 Normative references The following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) is applicable to this standard. GB/T 1019 General requirements for the package of household and similar electrical appliances GB/T 4214.1-2017 Test method for noise of household and similar electrical appliances - General requirements GB/T 5773 The method of performance test for positive displacement refrigerant compressors GB/T 7725 Room air conditioners GB/T 9237 Refrigerating systems and heat pumps - Safety and environmental requirements IEC 60335-2-34:2016 Household and similar electrical appliances - Safety - Part 2-34: Particular requirements for motor compressors Variable capacity compressor A compressor, whose working capacity is changed by mechanical and (or) electrical means. 3.7 Annual performance factor of compressor When the compressor is tested according to the prescribed test method, the performance index, that reflects the compressor's annual operating energy efficiency, which is obtained by referring to the calculation method of the annual performance factor of the air conditioner. Note: Refer to Appendix A for the test method of the annual performance factor of the speed controllable compressor. 4 Product classification 4.1 According to structure type, it can be divided into: a) Rotor compressor; b) Scroll compressor. 4.2 According to the type of power supply, it can be divided into: a) Single-phase power compressor; b) Three-phase power compressor. 4.3 According to the type of speed control, it can be divided into: a) Fixed speed compressor; b) Speed controllable compressor. 4.4 According to the change of cylinder capacity, it can be divided into: a) Fixed capacity compressor; b) Variable capacity compressor. 5 Requirements 5.1 Product technical specifications value of the compressor, when it is running under the test conditions. 6.5 Noise measurement This document adopts GB/T 4214.1-2017, as the method for determining the noise level of the compressor's A-weighted sound power level. The fixed-speed compressor is tested at the rated frequency. The speed controllable rotor compressor is tested at 60 Hz. The speed controllable scroll compressor is tested at 60 Hz (or 90 Hz). The variable capacity compressor is tested at full capacity AND 60 Hz. The compressor under test is placed in an occasion, that meets the requirements of the test environment in 4.4.1 of GB/T 4214.1-2017. The test environment is a semi-anechoic chamber. The compressor shall be equipped with its own damping pad. Place it on a rigid platform (with fixing bolts), in the center of the semi-anechoic chamber. The mass of the rigid platform shall be more than 10 times the mass of the compressor under test. The compressor is connected to the alternative cooling system, which is outside the semi-anechoic chamber, by a non-rigid connecting pipe. Alternative outdoor refrigeration system. The recommended alternative refrigeration system is as shown in Figure 2. The compressor is vacuumed AND filled with a suitable refrigerant. Run the compressor. Adjust the condensing temperature (dew point temperature), to stabilize it at 54.4 °C ± 0.3 °C. Adjust the evaporation temperature (dew point temperature), to stabilize it at 7.2 °C ± 0.2 °C. Adjust the thermostatic control water valve, to make the return air temperature reach to the suction temperature, which is same as that in the refrigeration capacity test. The system enters a steady state for 30 min. After the system is stable, it may start to measure the A-weighted sound pressure level AND noise value, at each point, according to the provisions of GB/T 4214.1-2017. Then calculate the average A-weighted sound pressure level's noise value of the measured surface. Calculate the compressor's A- weighted sound power level's noise value.
