A refrigerating appliance (100) is provided. The refrigerating appliance (100) comprises: at least one storage compartment (110) for storing goods to be refrigerated; a pressure sensor (180), a control unit (172) configured to control operation of the refrigerating appliance (100), the control unit (172) being in signal communication with said pressure sensor (180); wherein: said pressure sensor (180) is a MEMS pressure sensor configured to measure the pressure inside said at least one storage compartment (110) and to transmit to the control unit (172) a corresponding pressure signal proportional to said measured pressure, the control unit (172) being configured to control the operation of the refrigerating apparatus (100) based on the pressure signal received from the pressure sensor (180).

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.
