SANS 1125

This standard specifies requirements for single-package and split-system non-ducted air conditioners that employ air-cooled and water-cooled condensers and for heat pumps that employ air-cooled condensers. It is limited to systems that utilize a single refrigeration circuit and have one evaporator and one condenser. It covers air conditioners that are intended for operation on an a.c. power supply, single-phase not exceeding 250 V to earth, and three-phase not exceeding 418 V to earth, with a frequency of 50 Hz, and that have a cooling capacity not exceeding 12 000 W.

 

Total cooling capacity: When determined in accordance with SANS 5151, the total cooling capacity shall be at least 95 % of the value marked on the appliance. If the appliance is tested above sea level, the determined cooling capacity shall be increased by 0,24 % for each kilopascal of ambient air pressure below 101 kPa at the test site.

 

Heating capacity of heat pumps: When determined in accordance with SANS 5151, the heating capacity shall be at least 95 % of the value marked on the appliance. CAUTION: The total cooling and heating capacity tests shall be followed by the maximum and minimum operating conditions tests given in SANS 5151.
