Scope
This standard specifies the measurement requirements, measurement inspection procedures, measurement inspection methods, evaluation criteria for measurement inspection results, and inspection reports for the energy efficiency of multi-unit air conditioners with a climate type of T1.
This standard applies to the supervision and inspection of the energy efficiency of multi-unit air conditioners. For commissioned inspections, this standard can be referred to. Units that produce and sell multi-unit air conditioners can also conduct inspections in accordance with this standard.
The energy efficiency measurement inspection method specified in this standard is the air enthalpy difference method.
This standard does not apply to units with dual refrigeration cycle systems and multi-refrigeration cycle systems.
The multi-unit air conditioners accepted for inspection should be products that have passed the manufacturer's self-inspection or goods imported and sold by the seller.
