Scope

This specification specifies the measurement requirements, measurement testing procedures, and measurement testing for the energy efficiency of inverter air conditioners with air-cooled condensers, fully enclosed speed-controllable electric compressors, rated cooling capacity of 14,000 W and below, and climate type T1. Methods, measurement test results evaluation criteria and test reports, etc. This specification is applicable to the energy efficiency measurement supervision and testing of inverter air conditioners. Commissioned testing can refer to this specification. Units that produce and sell inverter air conditioners may also refer to this specification for testing. The energy efficiency measurement and testing method for inverter air conditioners stipulated in this specification is the air enthalpy method. The speed controllable type referred to in this specification includes the use of AC frequency conversion, DC speed regulation or other methods of changing the compressor speed. This specification does not apply to mobile air conditioners, multi-connected air conditioners and duct air conditioners. The inverter air conditioners to be tested should be products that have passed the manufacturer's self-inspection, or products imported and sold by the seller.
