Bus HVAC energy consumption test method based on HVAC unit behavior / M. Hegar in International journal of refrigeration, Vol. 36 N° 4 (Juin 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 4 (Juin 2013) . - pp. 1254–1262 Titre : Bus HVAC energy consumption test method based on HVAC unit behavior Titre original : Méthode d'essai pour déterminer la consommation d'énergie d'un système de chauffage, de ventilation et de conditionnement d'air d'un bus fondée sur le comportement du système Type de document : texte imprimé Auteurs : M. Hegar, Auteur ; M. Kolda, Auteur ; M. Kopecka, Auteur Année de publication : 2013 Article en page(s) : pp. 1254–1262 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Bus;  HVAC  unit;  Input  power;  Standard  engine;  Fuel  consumption;  Test  method Résumé : This paper presents a test method for determination of energy consumption of bus HVAC unit. The energy consumption corresponds to a bus engine fuel consumption increase during the HVAC unit operation period. The HVAC unit energy consumption is determined from the unit input power, which is measured under several levels of bus engine speeds and at different levels of testing heat load in the laboratory environment. Since the bus engine fuel consumption is incrementally induced by powering an HVAC unit, the results are subsequently recalculated to the unit fuel consumption under the defined road cycles in terms of standardized diesel engine. The method is likewise applicable either for classic or electric HVAC units with a main consumer (compressor or high voltage alternator) mechanically driven directly from the bus engine and also for electric HVAC units supplied from an alternative electric energy source in case of hybrid or fully electric buses.
