Abstract

Specifies the conditions on which the capacity and energy consumption of factory-made close control airconditioners are based and the test methods to be applied for determining the capacity and efficiency ratings.

Scope

This Standard specifies the conditions on which the capacity and energy consumption of factory-made close control airconditioners are based and the test methods to be applied to determine the capacity and efficiency ratings. This Standard covers equipment utilizing a single or multiple refrigerated direct expansion (DX) system designed to control and monitor temperature and humidity and may include supplementary conditioning equipment.
Appendix A establishes testing procedures. Appendix B describes the test facilities required for the calorimeter method. Appendix C provides formulae for calculating heating and cooling capacities. Appendix D describes methods for measuring airflow. Appendix E describes the refrigerant enthalpy test method. Appendix F lists the symbols used in this Standard.
This Standard does not cover the determination of seasonal efficiencies, which may be required in some countries.
