A process is for the pre-conditioning of one or more latent heat storage elements in the case of which the temperature or the narrow temperature range of the phase transition defines a target temperature and the latent heat storage elements are heated up to the target temperature. The latent heat, storage elements are cooled to an initial temperature below the target temperature and this initial temperature is determined. The latent heat storage elements at the initial temperature are introduced into a thermally insulated container and the container is then closed. The interior of the closed container is, or has been, connected to a heating device of which the thermal output which takes effect in the interior of the closed container is known. The initial temperature of the latent heat storage elements, the thermal capacity of the latent heat storage elements located in the container and also the target temperature of the latent heat storage elements are used to calculate the quantity of heat which has to be fed to the interior of the container in order for the latent heat storage elements to reach the target temperature (desired quantity of heat). The heating device is switched on and is operated continuously, or at intervals, until the desired quantity of heat has been fed to the interior of the dosed container.

The present disclosure illustrates a smart refrigerator including a user interface, a recipe management module, a storage management module and an order management module. The user interface is configured to input an ordering instruction. The recipe management module stores much recipe information recording information of ingredients required. The user can select at least one of the recipe information. The storage management module is configured to input and store the ingredient information. The order management module is configured to receive and store order information. The recipe management module transmits the selected recipe information to the storage management module, and the storage management module compares the received recipe information and the information of ingredient stored in the refrigerator, so as to generate the order information. When the ordering instruction is inputted into the user interface, the order management module transmits the order information to a cloud server. The smart refrigerator of the present disclosure has advantage of providing the user to more conveniently manage the ingredients stored in the refrigerator, and further providing functions of analyzing recipe and ordering ingredient online.

A control apparatus is configured for adjusting a control value for a refrigerating machine of a cooling system and performing control of the cooling system in conformity with an environmental condition. A controller has a data base having environmental condition cells in which control values for the refrigerating machine are respectively registered in association with respective environmental conditions. The control apparatus outputs a control value suitable for the present cooling state to the refrigerating machine, registers the control value in an environmental condition cell conformed with the present environmental condition and changes the control value to construct the data base when the environmental condition varies, the controller refers to an environmental condition cell conformed with the environmental condition, corrects a control value registered at the environmental condition cell in accordance with a tendency that the control value has been changed, and outputs the corrected control value to the refrigerating machine.

Disclosed is a process of selecting of a container and temperature-control system, such that biological products (including blood) requiring maintenance within a specified range of temperatures are so maintained during shipment. The process requires a prediction of the maximum period of shipment, and the predicted ambient temperature ranges and time of exposure thereto for the system during the period of shipment. With that information, a system of container(s) with temperature-control agents including dry ice, ice, frozen gel packs or a phase change material, is selected.
摘要:
A refrigerator and a method of operating a refrigerator to determine the time at which to initiate a defrost cycle is provided. Changes in the voltage provided to an evaporator fan are used to determine and/or predict when to initiate a defrost cycle. Adjustments to the timing of the defrost cycle can be made based on known periods of peak energy demand and/or the increased costs associated with operating the defrost cycle during such peak energy demand periods.
摘要:
The invention concerns a method for detecting changes in a first flow of a heating or cooling medium in a refrigeration system whereby the first flow is conveyed through a heat exchanger wherein occurs heat transfer from the first flow to a second flow of a heating or cooling medium. The earliest possible detection of the changes is desired. For this it is provided that for the supervision of the first media flow moving through the heat exchanger a change in the enthalpy of the second media stream or a value derived therefrom is determined.
摘要:
A method for cooling a bottle in a freezer compartment of a refrigerator includes sensing the temperature of a zone of the freezer in which the bottle is placed, estimating the temperature of the bottle on the basis of the compressor status and of the sensed temperature of the zone, and informing the user when the estimated temperature of the bottle has reached a set value. The method can also be used for an automatically adjusted “shock freezing” process for any kind of food.
