3 Terms and Definitions
The following terms and definitions as defined in GB/T 15765-2014 and GB/T 5773 apply to this document.
3.1
Compressor energy efficiency limit minimumalowablevaluesofenergyefficiencyforcompressors
The minimum allowable value of the coefficient of performance (COP) of the compressor under specified operating conditions.
4 Energy efficiency rating
4.1 Compressors are classified by energy efficiency based on measured COP, divided into 1, 2, and 3 levels. Level 1 indicates the most energy efficiency.
high. The corresponding coefficient of performance (COP) for each energy efficiency class shall not be less than that specified in Table 1.
