Abstract
A container refrigeration apparatus includes circuitry configured to control a pressure equalizer so that during a cooling operation for cooling of the inside of a container, the pressure equalizer performs a pressure equalizing action to equalize the pressure between the inside and the outside of the container when the pressure detected by a pressure sensor is lower than a predetermined first pressure being lower than the atmospheric pressure.
Claims20
A container refrigeration apparatus, comprising:
- a pressure sensor configured to detect a pressure of an inside of a container;
- a pressure equalizer configured to equalize the pressure of the inside of the container and a pressure of an outside of the container;
- and
- circuitry configured to control the pressure equalizer so that the pressure equalizer performs a pressure equalizing action to equalize the pressure of the inside of the container and the pressure of the outside of the container when the pressure sensor detects a pressure lower than a predetermined first pressure that is lower than an atmospheric pressure during a cooling operation in which the inside of the container is cooled.
A method for controlling a container refrigeration apparatus, the method comprising:
- detecting, by a pressure sensor, a pressure of an inside of a container;
- and
- controlling, by circuitry, a pressure equalizer to perform a pressure equalizing action to equalize the pressure of the inside of the container and a pressure of an outside of the container when the pressure detected by the pressure sensor is lower than a predetermined first pressure that is lower than an atmospheric pressure during a cooling operation in which the inside of the container is cooled.
A non-transitory computer-readable medium storing instructions that, when executed by circuitry of a container refrigeration apparatus, cause the circuitry to perform operations comprising:
- acquiring a pressure of an inside of a container detected by a pressure sensor;
- and
- controlling a pressure equalizer to perform a pressure equalizing action to equalize the pressure of the inside of the container and a pressure of an outside of the container when the pressure detected by the pressure sensor is lower than a predetermined first pressure that is lower than an atmospheric pressure during a cooling operation in which the inside of the container is cooled.
