A method of operating an air conditioning system includes operating a refrigeration unit to cool a volume of refrigerant and circulating the refrigerant to a heat exchanger. A serviced space is cooled via a thermal energy exchange between the serviced space and the refrigerant at the heat exchanger. Thermal energy generated by operation of the refrigeration unit is stored at a thermal energy storage system. An air conditioning system includes a refrigeration unit and a heat exchanger operably connected to the refrigeration unit. The heat exchanger is configured to transfer thermal energy between a serviced space and the refrigeration unit, thus cooling the serviced space. A volume of thermal energy storage medium is utilized to absorb thermal heat generated by the refrigeration unit for dissipation into the ambient environment at a selected time.

A refrigerator includes a cabinet having a storage space and a door configured to open and close the storage space. The door includes a panel assembly including a front panel and an insulating panel spaced apart from the front panel, a door frame that is in contact with the front panel, and a door liner which is connected to the door frame and is in contact with the insulating panel, the door liner being configured to define an insulating space, in which an insulator is disposed, together with the panel assembly and the door frame. The door liner includes a contact surface that is in contact with the insulating panel, and a recessed space is defined on the contact surface.
