The present invention provides a refrigeration device, wherein a chamber structure is provided with a refrigeration space, and further fitted with a return outlet flow pipe and a return inlet flow pipe. Cold from a cold source produced by a refrigeration chip passes through a temperature equalization plate or a heat conducting pipe to enter the interior of a refrigeration space. A return inlet flow pipe of the refrigeration device is inserted into a beverage and used to input the beverage to the interior of the refrigeration space for cooling thereof. The beverage is then output from the inside of the refrigeration space through the return outlet flow pipe into a cup. The refrigeration device thus achieves fast cooling of a beverage to produce a cold drink. The refrigeration device can be applied in medical treatment, beds, and clothing, as well as medical equipment to provide a cooling function.

Container assemblies and methods suitable for cooking, transporting, and storing the contents of the container assemblies while maintaining the contents therein at a desired temperature. Such a container assembly includes a container having a lower wall, side walls, and an opening opposite the lower wall that provides access to a cavity within the container. The container assembly further includes a lid configured to releasably attach to the side walls and thereby enclose the cavity to define a storage compartment. A thermal mass is coupled to an interior side of the lid such that at least a portion of the thermal mass faces and is exposed to the storage compartment when the lid is attached to the container. The thermal mass is configured to be heated to an elevated temperature or cooled to a reduced temperature and maintain the elevated or reduced temperature for a period of time.

Described embodiments provide systems and methods for managing the temperature of an item that includes a first flap portion and a second flap portion defining between them a first pouch containing substance; a third flap portion and the second flap portion defining between them a second pouch containing substance; a first portion of a fastener attached to the front side of the first flap portion; a first complementary portion of the fastener attached to the obverse side of the second flap portion; a second complementary portion of the fastener attached to the obverse side of the third flap portion.

Conventionally, chiller power consumption has been optimized by using Cooling Load based Control (CLC) approach which does not consider impact of a control strategy on other. Embodiments of the present disclosure provide reinforcement learning based control strategy to perform both chiller ON/OFF sequencing as well as setpoint leaving chilled water temperature (LCWT) scheduling. A RL agent is trained using a re-trained transfer learning (TL) model and LCWT, return chilled water temperature of target chillers and ambient temperature of building are read for determining required cooling load to be provided by target chiller(s) based on which target chillers are scheduled for turning ON/OFF. Transfer learning-based approach is implemented by present disclosure to predict power consumed by a chiller at some setpoint by using a model trained on similar chillers which were operated at that setpoint since chillers are usually run at a single setpoint.

A chest insert for a freezer is disclosed. The chest insert is placed inside a freezer and food is placed inside the chest insert. Several sides of the chest insert comprise a gap which is partially filled with a refrigerant gel. These gaps are slanted such that the gel can expand into a wider gap as it expands while freezing, lessening the risk of uneven freezing causing the refrigerant gel to press against the walls of the chest insert. The use of the disclosed subject matter reduces freezer burn by stabilizing humidity. Further, the chest insert maintains the temperature inside the chest insert for extended periods if the freezer fails or the power to the freezer is interrupted.
