Specifies procedures for calculating the performance of airconditioners and heat pumps of the vapour compression type up to a rated cooling capacity of 65 kW, for minimum energy performance standard requirements. It does not cover multi-split appliances or evaporative airconditioners. This Standard sets out a method of determining the performance of airconditioners using a combination of measured component performance, equipment operating conditions and a mathematical model to determine the appliance performance.

This Standard specifies procedures for calculating the performance of airconditioners and heat pumps of the vapour compression type up to a rated cooling capacity of 65 kW, for minimum energy performance standard requirements. It does not cover multi-split appliances or evaporative airconditioners. This Standard sets out a method of determining the performance of airconditioners using a combination of measured component performance, equipment operating conditions and a mathematical model to determine the appliance performance.This Standard can be used to quantify the following values for cooling and heating:(a) Rated cooling capacity.(b) Rated heating capacity.(c) Energy efficiency ratio (EER).(d) Coefficient of performance (COP).This Standard does not apply to the rating of the following:(i) Water-source heat pumps.(ii) Multi-split airconditioners and heat pumps. (iii) Mobile appliances having a condenser exhaust duct. Unitary systems where there is a thermal interaction between the evaporator and condensor.
