Scope of EN 12309 series Appliances covered by EN 12309 include one or a combination of the following: - gas-fired sorption chiller; - gas-fired sorption chiller/heater; - gas-fired sorption heat pump; EN 12309 applies to appliances only when used for space heating or cooling or refrigeration with or without heat recovery. Appliances can be monovalent, bivalent or hybrid types. EN 12309 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 applies to appliances that can be single ducted or double ducted. EN 12309 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 prEN 12309 1:2012) and EN 12309 applies to all such functions providing that the function concerned is dependent on circulation of fluid (refrigerant and/or solution) within the absorption, adsorption or refrigerant circuit(s). NOTE 1 Any appliance function that is not dependent on circulation of the fluid within the absorption, adsorption, or refrigerant circuit(s) should be assessed separately. EN 12309 is applicable to appliances that are intended to be type tested. Requirements for appliances that are not type tested would need to be subject to further consideration. In the case of packaged units (consisting of several parts), EN 12309 applies only to those designed and supplied as a complete package. EN 12309 does not apply to air conditioners. The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by EN 12309. Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309. NOTE 2 All the symbols given in this text should be used regardless of the language used. Scope of this Part 3 to EN 12309 This part of EN 12309 specifies the test conditions for the rating of energy parameters of gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW.
