Abstract
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).
Claims13
A refrigerating appliance comprising:
- at least one storage compartment for storing goods to be refrigerated;
- a refrigeration circuit configured to cool the at least one storage compartment;
- a pressure sensor;
- a control unit provided on a printed circuit board the control unit being electrically coupled to the refrigeration circuit and configured to control operation of the refrigerating appliance, the control unit being in signal communication with said pressure sensor;
- and
- at least one defrost heater in signal communication with the control unit,
- wherein:
- said pressure sensor is a MEMS pressure sensor configured to measure the pressure inside said at least one storage compartment and to transmit to the control unit a corresponding pressure signal proportional to said measured pressure, the control unit being configured to control the defrost heater and the refrigeration circuit of the refrigerating apparatus based on the pressure signal received from the pressure sensor, and
- the control unit is configured to activate the at least one defrost heater for a corresponding period of time, the control unit being further configured to:
- increase the duration of said corresponding period of time if the pressure signal is indicative of a decrease in the pressure inside said at least one storage compartment;
- and
- decrease the duration of said corresponding period of time if the pressure signal is indicative of an increase in the pressure inside said at least one storage compartment.
