scope:

Specifies the requirements and methods of test for the rational use of energy of gas-fired absorption and adsorption air conditioning and/or heat pump appliances having a net heat input not exceeding 70 kW, hereafter referred to as "appliances". Applies to appliances having flue systems of Type B12, B12BS, B13, B13BS, B14, B22, B23, C12, C13, C32 and C33, and to appliances designed for outdoor installations. Only applies to appliances having: - integral burners under the control of fully automatic burner control systems;- closed system refrigerant circuits in which the refrigerant does not come into direct contact with the fluid to be cooled or heated;- mechanical means to assist transportation of the combustion air and/or the flue gases. Appliances covered by this standard include one or a combination of the following: - gas-fired absorption air conditioner;- gas-fired adsorption air conditioner;- gas-fired absorption heat pump;- gas-fired adsorption heat pump. The above appliances can have one or more primary or secondary functions and this standard applies to all such functions providing that the function concerned is dependent on circulation of fluid within the absorption, or adsorption, refrigerant ciruit.
