Testing and rating including seasonal performance of air-to-air air-conditioners and heat pumps considering the effect of native control

Essai et détermination des performances, y compris les performances saisonnières, des climatiseurs et des pompes à chaleur air/air en tenant compte de la régulation intrinsèque des produits

Abstract / scope

This document applies to air-to-air air conditioners and heat pumps.
This document deals with test methods, test conditions, required measurement and calculation methods for determining capacity ratings and seasonal performance factors for heating and cooling including native control evaluation while minimizing the discrepancy between rating seasonal efficiency and average field performance.
This document provides specific requirements for load-based testing and/or CVP (standard loading, required measurements, calculations, and controls).
