A refrigerator includes a main body having a storage room formed therein, a door that opens and closes the storage room, a filter module, and a cool air circulation fan that circulates cool air through the filter module. The filter module includes a metal photocatalyst filter and a UV LED module for radiating UV rays to the metal photocatalyst filter. The metal photocatalyst filter has photocatalysts made of one of ZnTiO.sub.2, CuTiO.sub.2, AgTiO.sub.2 or FeTiO.sub.2 coated on a filter base. The filter module may allow the entire storage room to be uniformly subject to antibiosis and sterilization at a relatively low cost.

Disclosed herein is a drone docking station for deposit of items/goods delivered by a drone to a secured receptacle. Items can be delivered to a receptacle at a curb, mailbox, post, porch, mobile units, and window for a multi-parcel receptacle with a set of drawers with hot and cold sections in the station that has a specific residential/commercial address with various optional features. Features include communication systems between the station and drone; security; hot and cold temperature control and preservation of the goods before and after delivery; battery charging and exchange station; a collector to identify explosive materials, anthrax, etc.; ultraviolet system to eradicate disease, virus and harmful materials; an ozone applicator to eradicate disease, virus and harmful materials; weather monitoring; tag and track of vehicles and packages; facial recognition camera and software for pets and humans; and local two-way speakers; LED lights that strobe flash, and a flood light.

Delivering items to users by a delivery organization comprises a delivery container suitable to deliver multiple items that require storage at different temperatures 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 central panel in the delivery container to separate two compartments of the delivery container, each compartment to be cooled to a different temperature than the other. The delivery organization determines an appropriate coolant for each compartment based on heat transfer requirements of the compartment and positions the coolant in the bottom of each respective compartment. A panel is placed over each coolant and the items are placed in the appropriate compartments of the delivery container. A top panel is positioned on the delivery container to seal the delivery container.

A domestic refrigerator (1) comprises a thermally insulated housing (2), a cold storage compartment (5) and a fresh food compartment (4) contained within the housing (2) and located on top of each other, a refrigerant circuit which comprises an evaporator (29) configured to directly cool the cold storage compartment (5), a first door leaf (18) for closing and opening the fresh food compartment (4), a second door leaf (19) for closing and opening the cold storage compartment (5), a divisional wall (17, 42) separating the cold storage compartment (5) from the fresh food compartment (5), and a air channel system (31, 32) which is configured to allow an air exchange between the cold storage compartment (5) and the fresh food compartment (4).

The invention relates to a method for transporting heat-sensitive products in a refrigerated lorry of the indirect injection type, wherein the temperature T.sub.int inside the storage chamber is regulated by varying the pinch of the exchanger (Pinch=T.sub.int−TFluid outflow) according to the position of the internal temperature T.sub.int in relation to a temperature set value.

A portable water bottle has a bottle body, a lid assembly detachably connected to an upper end of the bottle body, a filter mounted in the lid assembly, a base detachably connected to a lower end of the bottle body, a temperature control module mounted in the base, and a power module mounted in the base. Liquid stored in the bottle body can be filtered by the filter when being poured out of the bottle body, so as to allow a user can drink the liquid directly and immediately. Moreover, the temperature control module is capable of heating or cooling down the liquid in the bottle body, so as to provide the user with the liquid having the temperature that is suitable for ambient it temperature or physical conditions of the user.

A heat pump system is provided that uses MCM to provide for heating or cooling. The heat pump can include one or more stages of MCM, each stage having an original peak Curie temperature. In the event the magneto caloric response of one or more stages of MCM degrades, the present invention provides for operating the heat pump system so that one or more stages of MCM are held at a different temperature from the original peak Curie temperature so as to restore the MCM to its original peak Curie temperature or to within a certain interval thereof. The present invention can be used with e.g., an appliance, air-conditioning systems (heating or cooling), or other devices using such a heat pump system as well.

A refrigerated merchandiser includes a refrigerated insulated cabinet having a front wall that is hingedly attached to the cabinet. The front wall is rotatable between a closed position covering a storage area in the cabinet and an open position permitting access to the storage area. An opening is provided in the front wall to permit merchandise to be removed from the storage area when the front wall is in the closed position. Adjusting the front wall to the open position permits pallets loaded with merchandise, including ice bags, to be loaded into the merchandiser with a wheeled lifting device such as a forklift or hand jack. The bottom wall of the merchandiser may be removable, such that the entire floor supporting the pallet may be removed and exchanged through the opened front wall. A roller may be provided on the front wall to help in adjusting the front wall between the open and closed positions.
