Development of an Energy Efficient Climate Controller 971789

The process of developing an energy efficient climate controller (EECC) is described. The purpose of the project was to reduce the energy consumption of the climate system in a car, still fulfilling the requirements of climate comfort in the car compartment.The energy efficiency of the EECC was determined by measuring the fuel consumption of the car at various climate conditions in the controlled environment of a climatic wind tunnel.The measurements show that the EECC reduces the fuel consumption by 1.6 % compared to an ECC (Electronic Climate Controller) of an existing production vehicle, when driven for one year in a European climatic zone.
