Abstract: A method for control of vapor pressure deficit for food preservation in a refrigerator. The method includes measuring the temperature and humidity of the food storage compartment, determining the vapor pressure deficit in the food storage compartment, and adjusting the temperature in the food storage compartment to maintain the vapor pressure deficit within the desired range.

Abstract: A refrigerator appliance may include a cabinet, a door, a camera module, a user-detection assembly, and a controller. The cabinet may define a chilled chamber. The camera module may be mounted to the cabinet within the chilled chamber. The camera module may be alternately activated in a low-power sleep mode and a high-power awake mode. The user-detection assembly may be mounted to the cabinet to detect a user presence independent from rotation of the door. The controller may be operably coupled to the camera module and the user-detection assembly. The controller may be configured to initiate an operation routine that includes receiving one or more detection signals from the user-detection assembly, determining a user presence based on the received one or more detection signals, and directing the camera module to the high-power awake mode from the low-power sleep mode in response to determining the user presence.

Abstract: An conditioner appliance, including methods for operating the same, is provided herein. The air conditioner appliance may include a housing, an outdoor heat exchanger, an indoor heat exchanger, a bulkhead, an outdoor fan, an indoor fan, one or more sensors, and a substitute control board. The housing may define an outdoor portion and an indoor portion. The outdoor fan may be disposed in the outdoor portion to direct an airflow across the outdoor heat exchanger. The indoor fan may be disposed in the indoor portion to direct an airflow across the indoor heat exchanger. The one or more sensors may be mounted within the housing. The substitute control board may be operably coupled to the outdoor fan, the indoor fan, and the one or more sensors. The substitute control board may be configured to initiate a service operation.
