MOREOVER, NEW TERMS AND DEFINITIONS USED IN THE OTHER PARTS HAVE BEEN ADDED AND EXISTING TERMS AND DEFINITIONS HAVE BEEN UPDATED CONSISTENTLY TO THE OTHER PARTS OF THIS STANDARD. - Appliances covered by this European 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 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 standard applies only to those designed and supplied as a complete package.
