4 Foreword This Malaysian Standard was developed by the Working Group on Minimum Energy Performance Standards (MEPS) for Air Conditioners under the authority of the Industry Standards Committee on Electrical and Electronics Equipments and Accessories. MEPS for electrical appliances have been introduced to Malaysian market since Since then, development has been carried out by to put MEPS requirement in the Electricity Regulation The amendment of Electricity Regulation 1994 enables the enforcement of MEPS and labelling to specified electrical appliances. Compliance with a Malaysian Standard does not of itself confer immunity from legal obligations. STANDARDS MALAYSIA All rights reserved iii

5 Minimum energy performance standards (MEPS) for air conditioners 1 Scope This Malaysian Standard specifies minimum energy performance standard (MEPS) and energy labelling requirements for single-phase non-ducted single split wall mounted type vapour compression air conditioners with cooling capacity up to 7.1 kw. The models that have been granted exemption by the relevant authority is excluded from the scope of this standard. 2 Normative references The following normative references are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the normative reference (including any amendments) applies. MS ISO 5151, Non-ducted air conditioners and heat pumps: Testing and rating for performance 3 Terms and definitions For the purposes of this standard, the following terms and definitions apply. 3.1 energy efficiency ratio (EER) Ratio of the total cooling capacity to the effective power input at any given set of rating conditions. The unit is (Btu/h)/W. NOTE. Cooling capacity in terms of 1 W (watt) = Btu/h. 3.2 inverter air conditioners Air conditioners employ technologies that vary the output of the compressor, by means other than start-stop operation. 3.3 minimum energy performance standards (MEPS) The minimum level of energy efficiency which has to be met by each of applicable air conditioners. 3.4 non inverter air conditioners Air conditioners employ technologies that control the output of the compressor by start-stop operation.

6 3.5 star rating The number of stars displayed on the energy label. Available stars are between a minimum of one and a maximum of five. 3.6 wall mounted air conditioners An encased assembly that consists of at least an evaporator, fan motor assembly and electrical assembly and mounted on a wall. Primarily designed to provide free delivery of conditioned air to an enclosed space, room or zone. 4 Measuring condition 4.1 The cooling capacity value shall be determined in accordance with the MS ISO 5151 or identical under condition stated below: a) 100% Load Cooling Capacity Test (inverter and non inverter air conditioners); and b) 50% Load Cooling Capacity Test (inverter air conditioners only). For 50% Load Cooling Capacity Test, the following tolerance shall be met as followed. 50 % Load = 100 % Load capacity x 0.5 (tolerance ± 0.1 kw or ±2.5%, whichever is larger) where 100 % load capacity refers to measured cooling capacity during 100 % Load Cooling Capacity test. 4.2 For non-inverter air conditioners the EER is given by the following equation: where EER Cooling Capacity (Btu/h) Input Power (W) Cooling capacity refers to measured cooling capacity during 100% Load Cooling Capacity test and the inverter air conditioners is given by the following equation : 100 %Load Cooling Capacity 50 %Load Cooling Weighted EER %Load Input Power 50 %Load Input Capacity Power 2 STANDARDS MALAYSIA All rights reserved

7 5 Star rating The star rating for the rated cooling capacity < 4.5 kw and 4.5 kw rated cooling capacity 7.1 kw shall be in accordance with Table 1 and Table 2 respectively. 6 MEPS requirement Table 1. The rated cooling capacity < 4.5 kw Star rating Tested EER (Btu/h) / W to to to to 9.55 Table kw rated cooling capacity 7.1 kw Star rating Tested EER (Btu/h) / W to to to to 8.02 The MEPS requirement shall accordance with relevant regulatory requirements.
