Résumé

This study presents a new test method for determination of energy consumption of bus HVAC units. The energy consumption corresponds to a bus engine fuel consumption increase during the operation period of the HVAC unit. The bus engine fuel consumption incrementally induced by powering an HVAC unit is determined from the HVAC unit total input power measured under four levels of bus engine speeds and at three levels of total heat load in the laboratory environment. The tested HVAC unit operates in automatic temperature control mode for one hour after reaching setpoint for each test condition. The results are subsequently recalculated to the HVAC unit fuel consumption under the defined road cycles. Therefore, the fuel consumption data gained in this way can give a true picture of real operating conditions.
