Appliances covered by BS EN 12309-2:2015 include one or a combination of the following:

• gas fired sorption chiller;
• gas fired sorption chiller/heater;
• gas fired sorption heat pump.

This European Standard applies to appliances only when used for space heating and cooling with or without heat recovery.

This European Standard applies to appliances having flue gas systems of type B and C (according to CEN/TR 1749) and to appliances designed for outdoor installations. EN 12309 does not apply to air conditioners, it 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 water or air to be cooled or heated;
• mechanical means to assist transportation of the combustion air and/or the flue gas.

The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions in EN 12309-1:2014). In the case of packaged units (consisting of several parts), the standard applies only to those designed and supplied as a complete package.

The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by this European Standard. Installations used for heating and/or cooling of industrial processes are not within the scope of these standards.
