This specification specifies the measurement requirements, measurement and testing procedures, measurement and testing methods, evaluation criteria for measurement and testing results, and testing reports for energy efficiency of multi line systems with climate type T1. This specification is applicable to the supervision and testing of multi line energy efficiency measurement, and entrusted testing can refer to this specification. Units that produce and sell multiple units can also refer to this specification for testing. The measurement and detection method for multi line energy efficiency specified in this specification is the air enthalpy difference method. This specification does not apply to units with dual refrigeration cycle systems and multiple refrigeration cycle systems. The multi line tested should be products that have passed the producer's self inspection, or products imported or sold by the seller
