A method for operating a refrigeration system for a container for refrigerating chilled cargo, and a system employing the method. The method includes providing a refrigeration system (100) including a compressor (110), a condenser (120), an evaporator (140), an evaporator fan (150), and a heater. The method also includes determining the temperature of the supply air discharged into the container and the return air from the container, determining one of a requirement for heating and a requirement for cooling based on the temperatures of the return air and the supply air, activating the evaporator fan (150) when a requirement for heating is determined and increasing the speed of the evaporator fan when increased heating is determined, and activating the compressor (110) and the evaporator fan (150) when a requirement for cooling is determined and increasing the power supplied to the compressor and maintaining the evaporator fan at a first speed when increased cooling is determined. |
