SASO 2663:2018 MEPS Small air conditioners

Minimum energy performance, labelling and testing requirements for low capacity window type and single-split air conditioners (entry into force: 16th August, 2018) This standard supersedes the previous standard: SASO 2663:2014 "Energy Labelling and Minimum Energy Performance Requirements for Air-Conditioners". The standard was updated in order to: 1- Improve the minimum energy efficiency requirements (MEPS) 2- Clarify the definitions for rated values, tested values and acceptance criteria. 3- Update the label design This standard specifies the Minimum Energy Performance Standard (MEPS) and the energy labelling requirements for single-package of window type, single split-system non-ducted air conditioners using air-cooled condensers, single split-system ducted air-conditioners using air-cooled condensers, and heat pumps using air-cooled condensers or using electric resistance for residential, commercial and industrial sector as applicable in accordance with SASO standards. The standard applies to units designed to operate with the following voltages: - AC single phase circuits of 220 V or 230 V, - DC single phase up to 400V, - Designed for dual voltage (including DC) up to 400V, - Voltage range including above values, and three phase circuits of 380 V or 400 V - At frequency of 60 Hz. The standard covers units with capacities up to and including 65,000 Btu/h (19 kW). MEPS (EER Values (Btu/h)/W): Single package of Window type – CC = 24,000 Btu/h (7,050W) : T1* - 9.80 ; T3** - 7.00 Single package of Window type - 24,000 (7,050W) < CC = 65,000 (19,050 W) : T1* - 9.00 ; T3** - 6.20 Split type ducted and non-ducted using aircooled condensers, heat pumps using air cooled condensers - CC = 65,000 (19,050 W) : T1* - 11.80 ; T3** - 8.30 *T1 - testing conditions: indoor section dry-bulb 27°C, wet-bulb 19°C, outdoor section dry-bulb 35°C, wet bulb 24°C *T3 - testing conditions: indoor section dry-bulb 29°C, wet-bulb 19°C, outdoor section dry-bulb 46°C, wet bulb 24°C
