METHOD FOR REDUCING FUEL CONSUMPTION

A method of operating a condenser of a transport refrigeration unit (TRU) of a vehicle, the method comprising:determining whether revolutions per minute (RPM) of an engine of the vehicle exceeds a predefined level;computing an air flow due to motion of the vehicle from the RPM of the engine if the RPM of the engine exceeds the predefined level;obtaining a nominal air flow due to motion of the vehicle for which the condenser is rated;determining whether the air flow due to motion of the vehicle is equal to or greater than the nominal value; andswitching the condenser off if the air flow due to motion of the vehicle is equal to or greater than the nominal value.
