The present invention discloses a refrigerator controlling method and system with a linear compressor. The method comprises: monitoring an environment temperature T of the refrigerator located in the environment comparing the environment temperature T with a preset environment temperature threshold T0; if T is larger than T0, controlling a refrigerating unit and/or a heating unit in the refrigerator such that the refrigerator runs under a first operation condition; and if T is smaller than or equal to T0, controlling the refrigerating unit and/or the heating unit in the refrigerator such that the refrigerator runs under a second operation condition. When the linear compressor runs within predetermined time, a refrigeration amount of the linear compressor under the second operation condition is controlled to be larger than a refrigeration amount of the linear compressor under the first operation condition, such that a compartment of the refrigerator reaches a target temperature.

A frame for a refrigerated enclosure includes a frame segment having, in cross-section, a main frame member including a base, a middle wall, and a forward flange. The forward flange of the main frame member absorbs heat from the ambient air to increase a temperature of one or more locations of the frame segment or a door of the refrigerated enclosure.

A method for controlling the temperature and humidity level of the air contained in an enclosed refrigerated space includes the step of measuring the temperature of air in the space. The space includes a cooler having a plurality of cold batteries; at least one coolant temperature sensor at the input and at least one coolant temperature sensor at the output of the cooler; at least one fan with an adjustable, reversible direction of ventilation for producing a variable flow of air through the cooler; at least one temperature sensor upstream of the fan; at least one temperature sensor downstream of the cooler; at least one humidity level sensor upstream of the fan; and at least one humidity level sensor downstream of the cooler. The control is affected by reference values given initially for the temperature and humidity level in the enclosed space.

A refrigerator has a refrigeration compartment, a drawer located inside the refrigeration compartment, and a lid adapted to open or close the drawer. The refrigeration compartment includes: a support module, mounted on an inner side wall of the refrigeration compartment, where the support module includes an elastic member; and a motor module, including a motor, a cam, and a connection portion connected to the lid and the cam. The motor drives the cam to generate a first rotation to push the connection portion to move upward, to cause the lid to compress upward the elastic member, so that the lid ascends to a first position. The motor further drives the cam to generate a second rotation to push the connection portion to move downward, to cause the connection portion and the elastic member to push downward the lid, so that the lid descends to a second position.

A method for controlling a refrigerator, includes turning off a cold air transmission unit as a temperature of a storage compartment becomes equal to or less than a second reference temperature while a cold air generator is operated, turning on the cold air transmission unit, upon determining that the temperature of the storage compartment is equal to or greater than a first reference temperature which is greater than the second reference temperature, and calculating, by a controller, an operating ratio of the cold air transmission unit based on ON and OFF time of the cold air transmission unit, determining an output of the cold air transmission unit based on the operating ratio of the cold air transmission unit, and operating the cold air transmission unit with the determined output, upon determining that the temperature of the storage compartment is equal to or less than the second reference temperature.

Systems and methods are provided for bimodal refrigeration, which uses a combination of mechanical refrigeration and phase change material (PCM) cells to provide cooling for one or more units of storage, such as freezers, coolers, storage or display cases, open cases (without doors), closed cases (with doors), rack systems (with compressors located remotely), self-contained refrigeration systems (with embedded compressors), in an optimal and efficient manner. In some embodiments, the systems and methods employ intelligent controls which may monitor and receive input for system conditions, time of day, and other conditions, and turn on/off the mechanical refrigeration as appropriate to provide for efficient and cost-effective use of energy.

An artificial intelligent refrigerator is disclosed. The artificial intelligent refrigerator includes: one or more first temperature sensor that senses refrigerating compartment-internal temperature in a refrigerating compartment of the refrigerator; one or more second temperature sensor that senses freezing compartment-internal temperature in a freezing compartment of the refrigerator; and a refrigerator processor that calculates a load accumulation amount for food put in the refrigerator on the basis of the refrigerating compartment-internal temperature or the freezing compartment-internal temperature, and performs a load correspondence operation using the calculated load accumulation amount. According to the artificial intelligent refrigerator of the present disclosure, one or more of a user terminal, and a server of the present disclosure may be associated with an artificial intelligence module, a drone ((Unmanned Aerial Vehicle, UAV), a robot, an AR (Augmented Reality) device, a VR (Virtual Reality) device, a device associated with 5G services, etc.

Delivering items to users by a delivery organization comprises a delivery container suitable to deliver items that require storage at a specific temperature range for the duration of the delivery. The delivery container may be a cube or a rectangular prism constructed of an insulating material. The delivery organization may position a panel in the delivery container to separate a chilled compartment from a compartment with a coolant. The panel between the compartments includes a pressure relief valve that opens when the pressure difference between the compartments reaches a set point. The open valve allows the chilled compartment to exchange air with the compartment with the coolant until the drop in the pressure difference allows the valve to close. The temperature in the chilled compartment is maintained in the desired range by the opening and closing of the valve.

A method for adjusting temperature controls of a refrigerator appliance. The method includes scanning an indicium with a user interface, transmitting data corresponding to a registration request from the user interface to a server, and receiving, at the user interface, data corresponding to a temperature control adjustment instruction from the server.

An AI agent includes an information receiver configured to receive a purchase history of an article and determine whether or not a new article for storage in refrigerator requiring refrigeration or freezing storage exists in the purchase history, an information collector configured to collect capacity information on the new article for storage in refrigerator and movement path information on the new article for storage in refrigerator when the new article for storage in refrigerator exists in the purchase history, and an agent controller configured to determine an expected arrival time at which the new article for storage in refrigerator is to be received in a refrigerator based on the movement path information, and transmit the movement path information and the capacity information and the expected arrival time information on the new article for storage in refrigerator to the refrigerator.
