Draft of the Egyptian standard "Multiple split-system air conditioners and air-to-air heat pumps — Testing and rating for performance "; (102 page(s), in English)

This draft of Egyptian standard specifies the performance testing, the standard conditions and the test methods for determining the capacity and efficiency ratings of air-cooled air conditioners and air-to-air heat pumps.

It is applicable to the following equipment:

Basic multi-split systems, modular multi-split systems and modular heat recovery multi-split systems. These multi-split systems include air-to-air systems with non-ducted and/or ducted indoor units with integral fans and indoor units supplied without fans.

It is limited to:

- Residential, commercial and industrial split-system air conditioners and heat pumps;

- Factory-made, electrically driven and use mechanical compression;

- Single- and multiple-circuit split-systems which utilize one or more compressors with no more than two steps of control of the outdoor unit; or

- Split-systems with a single refrigeration circuit which utilize one or more variable-speed compressors or alternative compressor combinations for varying the capacity of the system by three or more steps.

Worth mentioning is that this Draft standard adopts the technical content of ISO 15042:2017/AMD 1:2020
