Abstract
A refrigeration system 1a includes a refrigerated compartment 2 for storing perishable goods; a refrigeration unit 10 operably coupled to the refrigerated compartment 2; a plurality of sensors including an internal temperature sensor 4 configured to determine a temperature of the refrigerated compartment 2, and a weight sensor 5a configured to determine a weight of the goods located within the refrigerated compartment 2; and a controller 20 configured to: receive data from the plurality of sensors; determine a thermal inertia parameter of the goods located within the refrigerated compartment 2 based upon the temperature of the refrigerated compartment 2 and the weight of the goods; and adjust a mode of operation of the refrigeration unit 10 in accordance with the thermal inertia parameter of the goods.
Claims6
A refrigeration system comprising:
- a refrigerated compartment for storing perishable goods;
- a refrigeration unit operably coupled to the refrigerated compartment;
- a plurality of sensors including an internal temperature sensor configured to determine a temperature in the refrigerated compartment, and a weight sensor configured to determine a weight of the goods located within the refrigerated compartment;
- and
- a controller configured to:
- receive data from the plurality of sensors;
- determine a weight and a temperature of the perishable goods located within the refrigerated compartment based on the data from the plurality of sensors;
- run the refrigeration unit until the internal temperature of the refrigerated compartment reaches a target temperature of the perishable goods;
- adjust predetermined bounds of the target temperature based on the weight and temperature of the perishable goods located within the refrigerated compartment;
- stop running the refrigeration unit until the internal temperature of the refrigerated compartment is outside the predetermined bounds of the target temperature of the perishable goods;
- and
- resume running of the refrigeration unit;
- wherein the plurality of sensors further comprises a camera positioned within the refrigerated compartment and configured to monitor the refrigerated compartment;
- and wherein the controller is configured to:
- determine that the internal temperature of the refrigerated compartment is outside predetermined bounds of the target temperature of the perishable goods within the refrigerated compartment, operate the camera to monitor an air vent of the refrigerated compartment, and raise an alert signal responsive to determining that the air vent of the refrigerated compartment is obstructed.
