发明名称 Controlling chilled state of a cargo
摘要 A method for operating a refrigeration system for a container for refrigerating chilled cargo includes providing a refrigeration system including a compressor and an evaporator fan associated with an evaporator. The method also includes determining the temperature of supply air and the temperature of return air. The method further includes determining one of a requirement for heating and a requirement for cooling based on the temperature of the return air and the temperature of the supply air. The method additionally includes activating the evaporator fan when a requirement for heating is determined and increasing the speed of the evaporator fan when increased heating is determined. The method also includes activating the compressor and the evaporator fan 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.

主权项 1. A method for operating a refrigeration system for a container for refrigerating chilled cargo, the method comprising: providing a refrigeration system including a compressor, a condenser, and an evaporator connected in series, an evaporator fan associated with the evaporator, and a heater, the refrigeration system operable to discharge supply air to the container and to receive return air from the container; determining the temperature of the supply air; determining the temperature of the return air; determining one of a requirement for heating and a requirement for cooling based on the temperature of the return air and the temperature of the supply air; activating the evaporator fan when a requirement for heating is determined and increasing the speed of the evaporator fan when increased heating is determined; and activating the compressor and the evaporator fan 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.
