1.1Scope of EN 12309 Appliances covered by this standard 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 designed to be used for space heating or cooling or refrigeration with or without heat recovery.This European Standard applies to appliances having flue gas systems of type B and type 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), this European 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 EN 12309.Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.All the symbols given in this text should be used regardless of the language used.1.2Scope of this Part 6 to EN 12309This part of EN 12309 specifies the calculation methods of seasonal performances for gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW. It deals in particular with the calculation methods of reference seasonal performances in cooling and heating mode for monovalent and bivalent appliances.NOTEThis European Standard serves as an input for the calculation of the system energy efficiency in heating mode of specific heat pump systems in buildings, as stipulated in EN 15316-4-2.
