JJF 1769-2019 Rules of Metrology Testing for Energy Efficiency of Unitary Air Conditioners

Scope

This standard specifies the measurement requirements, measurement and inspection procedures, measurement and inspection methods, evaluation criteria for measurement and inspection results, and inspection reports for the energy efficiency of unit air conditioners, ducted air conditioners, and rooftop air conditioning units (hereinafter referred to as "air conditioners") with a nominal cooling capacity of more than 7,100 W and driven by electric motors.
This standard applies to the supervision and inspection of the energy efficiency of air conditioners. For commissioned inspections, this standard can be referenced. Units that produce and sell air conditioners can also conduct inspections in accordance with this standard.
The energy efficiency measurement method for air conditioners specified in this standard is the air enthalpy difference method.
This standard does not apply to multi-zone air conditioning (heat pump) units and frequency-converted air conditioners.
The air conditioners accepted for inspection shall be products that have passed the manufacturer's self-inspection or goods imported and sold by the seller.
