The refrigerator production line includes a conveying device for conveying an assembled refrigerator; a scanning device for scanning and confirming an identification code of the assembled refrigerator and an address code of a communication module in the assembled refrigerator; and a local server for saving the identification code of the assembled refrigerator and the address code of the communication module and further acquiring, in response to a firmware upgrade request, a firmware upgrading package for the assembled refrigerator that corresponds to the identification code. After the assembled refrigerator is powered on, the communication module receives the firmware upgrade package, and a control module upgrades a public version software program according to the firmware upgrade package.

Storage apparatus having a plurality of lockable storage compartments, wherein at least some of the storage compartments are temperature controlled. Storage compartment temperature information, SCTI, indicative of a locker temperature category of each storage compartment is obtained. Order information associated with an order of a plurality of items for storage is received, including desired temperature information, DTI, associated with the items, and temperature tolerance information, TTI, associated with the items. The TTI indicates a thermal resilience of the items. In dependence on the SCTI and the DTI, a capacity of the plurality of lockable storage compartments for receipt of the order is identified, corresponding to the DTI for the associated items. A subset of the plurality of lockable storage compartments is determined for storage of the items, in dependence on the identified capacity, DTI and TTI. The subset of lockable storage compartments is unlocked responsive to arrival of the order.

Provided is a sensor package in a refrigerator configured to provide information related to refrigerated food. The sensor package may include a body having a mark classified by a type of food allocated to the sensor package and indicating the type of food of a food to which the sensor package is coupled, a battery, an operation switch, a memory configured to store food information corresponding to the type of food corresponding to the mark, a sensor communication module that communicates with a display provided in the refrigerator, a sensing module that senses state information associated with the food, and a sensor control module that controls the sensor communication module to initiate communication between the sensor package and the display of the refrigerator based on the state information sensed by the sensing module.

A refrigerant leak detection and mitigation system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates a refrigerant gas sensor (RGS), sensor signal conditioner (SSC), alarm status indicator (ASI), and digital control processor (DCP) is disclosed. The RGS detects ambient refrigerant gas (ARG) and indicates this as a refrigerant sensor voltage (RSV) to the SSC. The DCP and SSC form a closed control loop (CCL) in which the SSC electrical characteristics are adjusted by the DCP such that the RSV is continuously and dynamically recalibrated to account for background refrigerant gas levels, changes in ambient air conditions, RGS manufacturing tolerances, and other field-specific operational conditions that impact the RGS detection capabilities. The DCP is configured to log alarms to the ASI if a RGS refrigerant leak is detected and optionally shutdown one or more HVAC system components such as a specific air handler leaking refrigerant.

An appliance includes a temperature control system, a light source, and a spectrometer. The spectrometer works in conjunction with the light source to obtain a measured value of a foodstuff. The measured value is at least one of an absorbance value, a transmittance value, and a reflectance value. The measured value from the foodstuff is compared to a reference value for the foodstuff.

A control method and a control system for a compressor in a refrigeration system, implements control logic based on the monitoring of parameters of the refrigeration system, where these parameters may include, for example, a previous load (C.sub.ant), a current load (C.sub.atu), a reference load (C.sub.ref), a measured cycle time (t.sub.cycle) and a target time (t.sub.target).

A method for controlling and managing a front door refrigerator using an application installed in a recording medium, according to an embodiment of the present invention, comprises: a step in which a user logs into a front door refrigerator control application installed in a recording medium including a mobile device, thereby allowing a main screen including menu display regions to be displayed on a display unit of the mobile device; and a step in which a storage information confirmation menu is selected from among a plurality of execution menus displayed in the menu display regions, wherein, when the storage information confirmation menu is selected, storage information of a product stored in the front door refrigerator is output to the display unit of the mobile device.

A mouthfeel maintaining method of an ice cream machine is provided. The ice cream machine is equipped with a freezing cylinder, a stirring device, a main refrigeration system, and a control system. When the ice cream material in the freezing cylinder is in a forming solid stage, the control system controls the ice cream machine to enter a mouthfeel maintaining state. The forming solid stage is: a stage from when all the ice cream material in the freezing cylinder is converted into all-solid ice cream until the preset hardness or the preset viscosity value is reached. The mouthfeel maintaining state is as follows that: the main refrigeration system refrigerates the ice cream material in the freezing cylinder according to the refrigeration capacity close to the lower limit refrigeration capacity. Moreover, the ice cream machine can discharge the all-solid ice cream in the freezing cylinder in the mouthfeel maintaining state.
