DIN EN 14825:2016-10

This European Standard covers air conditioners, heat pumps and liquid chilling packages. It applies to factory made units defined in EN 14511-1:2011, except single duct, control cabinet and close control units. This European Standard gives the temperatures and part load conditions and the calculation methods for the determination of seasonal energy efficiency SEER and SEER_on, seasonal coefficient of performance SCOP, SCOP_on and SCOP_net, and seasonal space heating energy efficiency ns. Such calculation methods may be based on calculated or measured values. In case of measured values, this European Standard covers the test methods for determination of capacities, EER and COP values during active mode at part load conditions. It also covers test methods for electric power consumption during thermostat-off mode, standby mode, off-mode and crankcase heater mode. The word "unit" is used instead of the full terms of the products. This document (FprEN 14825:2015) has been prepared by Technical Committee CEN/TC 113 "Heat pumps and air conditioning units", the secretariat of which is held by AENOR (Spain). Regarding the German collaboration, the responsible committee is Working Committee NA 044-00-06 AA "Elektromotorisch angetriebene Wärmepumpen und Luftkonditionierungsgeräte" ("Heat pumps with electrically driven compressors") at DIN Standards Committee Refrigeration Technology (FNkä).
