 ENERGY LABELLING AND MINIMUM  
ENERGY PERFORMANCE REQUIREMENTS  
FOR AIR -CONDITIONERS  
 
1. SCOPE  AND OBJECTIVE  
1.1 Scope  
 This standard specifies the energy labelling requirements and the Minimum 
Energy Performance Standard (MEPS) requirements for single -package (such as 
window type) and split -system non -ducted air conditioners using air - and water -
cooled condensers and heat pumps employing air -cooled condensers and ducted  
air-conditioners using  air-to-air heat pumps for residential , commercial and 
industrial sector as applicable in accordance with Qatari  standards.  
1.2 Objective  
 The objective of this standard is to:  
a) Provide detailed information on the performance and energy labelling 
requirements which an air conditioning  appliance has to meet in order to 
carry a valid energy efficiency label; and  
b) Provide detailed information on the performance requirements which a n 
air-conditioning appliance has to meet in order to meet minimum energy 
performance standard requirements.  
 
2. NORMATIVE REFERENCES  
         Updated editions of the following normative ref erences  are applied  (Including any  
         changes on these normat ive references).  
 
2.1 QS ISO :5151 “Non-ducted air conditioners and heat Pumps -Testing and rating 
for Performance” . 
2.2 QS ISO :13253 “Ducted air -conditioners and air -to-air heat Pumps - Testing and 
rating for Performance ”. 
 
3. TERMS AND DEFIN ITIONS  
 For the purposes of this standard, the terms and definitions given in QS 
mentioned in sub -clauses 2.1 and 2.2 and those below are considered.  
3.1 Ducted air conditioners  
 An air conditioner  model configuration where the indoor side is situated remote 
to the space to the conditioned.  The conditioned air is supplied or extracted via 
a duct.  
3.2 Non-ducted air conditioner  
 An air conditioner  model configuration where the indoor side is situate d partly 
or wholly within the space to be conditioned.  The conditioned air is supplied 
and extracted directly to and from the conditioned space.  FinaL DraftQATAR STANDARD  QS  2663/2020

 3.3 Rated capacity  
 The nominal rated capacity claimed by the manufacturer of an air conditioner  
model determi ned as follows, as applicable:  
(a) Rated total cooling capacity   as claimed by the manufacturer for 
temperature condition T1 and T3.  (Units: Btu/h).  
(b) Rated heating capacity   as claimed by the manufacturer for temperature 
condition H1.  (Units Btu/h).  
 The rated capacity appears on the energy label as ‘Capacity Output’ (heating 
and/or cooling as applicable.  (Units: Btu/h).  
3.4 Rated power  
 Effective power input of the air conditioner  model as claimed by the 
manufacturer during the determination of rated cooling capacity and rated 
heating capacity, as applicable.  (Units: W or kW.)  
3.5 Split system  
 An air conditioner  with separate indoor and outdoor components that are 
connected with refrigerant piping.  The indoor unit usually lies within the 
conditioned space and may be installed or portable/mobile.  
3.6 Star rating  
 The number of stars displayed on the energy label.  Available stars are between 
a minimum of one and a maximum of six.  It is considered as an indication of 
the claimed energy efficiency of a model at rated conditions.  A higher star rating 
indicates a higher energy efficiency.  It is derived from the measured EER.  
3.7            Estimated annual energy consumption  
                 Rated power expected within 2700 working hour with a full load annually.  
                 Formula to calculate  the Estimated Annual Energy Consumption:  
                 Estimated Annual Energy Consumption = (Total  Input Power i n KW at (T1) 
conditions)  x (2700  hours/year ).   
 
 
4. REGISTRATION REQUIREMENT S
