Forward

The Public Authority for Industry (PAI), through the program of energy efficiency of air

conditioners subcommittee of (The National Committee for the Sector of Electrical and

Electronics Standards) prepared the Kuwaiti Technical Standard Number 1893:2018

“Energy Efficiency Labelling Requirements and the Minimum Energy Performance

Standard (MEPS) requirements for DX air conditioners”


4

1. SCOPE

This standard specifies the requirements of 1) energy efficiency labelling and 2) Minimum

Energy Performance Standard (MEPS) for air-cooled DX air conditioners with capacities

including and up to 70,000 Btu/h. It is applied to units designed to operate in AC single

phase circuits of 240 V, and three phase circuits of 415 V with a frequency of 50 Hz.

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;

b) Provide detailed information on the performance requirements which an air

conditioning appliance has to achieve in order to meet minimum energy

performance standard requirements.

3. NORMATIVE REFERENCES

The following normative references are applied, taking in account the differences in this

standard:

MEW/R-6 “Energy Conservation Program, Code of Practice - Kuwait”.

GSO ISO 5151 "Non-Ducted Air-Conditioners and Heat Pumps – Testing and

Rating for Performance".

GSO ISO 13253 “Ducted Air-Conditioners and Air-to-Air Heat Pumps – Testing

and Rating for Performance”.


5

4. TERMS AND DEFINITIONS

For the purposes of this standard, the terms and definitions given in GSO/KWS

Standards mentioned in Section 3 and those below are considered.

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.

DX air-conditioners

Air-conditioners that direclty cools the space by boiling the refrigerant in the evaporator, and condenser is cooled by ambient air (e.g.: mini-split unit, ducted split units, VRF, packaged units, etc.).

Non-ducted air-conditioner

An air-conditioner model configuration where the indoor side is situated partly

or wholly within the space to be conditioned. The conditioned air is supplied

and extracted directly to and from the conditioned space.

Package system

A self-contained air-conditioner with all its components assembeled into one

casing. It is usually installed outside of the conditioned space.

Rated capacity

The nominal rated capacity claimed by the manufacturer of an air-conditioner model determined as follows:

- Rated total cooling capacity As claimed by the manufacturer for

temperature condition T1 and T4. (Units: Btu/h).

The rated capacity at T4 appears on the energy label as ‘Capacity Output’

(Units: Btu/h).

Rated power

Effective power input of the air-conditioner model as claimed by the

manufacturer during the determination of rated cooling capacity.

(Units: W or kW.)

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.

Star rating

The number of stars displayed on the energy effecincy label. Available stars are


6

between a minimum of one and a maximum of four for window A/C type

and seven stars for other A/C types. 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 tested EER .

T4

Test conditions where the outdoor design temperature is (48ºC DBT &26.9ºC WDT) & the indoor design temprature is (26.6ºC DBT & 19.4ºC WBT)
