A transportation refrigeration system and a CAN ID allocation method for a transportation refrigeration system. The transportation refrigeration system includes: a refrigeration circuit including a compressor, a condenser, and a plurality of evaporators connected in parallel, all of which are connected to form a loop; a plurality of chambers, each of the evaporators being located in one of the chambers to adjust the chamber; a plurality of sensors of the same type, each of the sensors being installed in one of the chambers respectively; and a control unit, after being installed in place and energized, the plurality of sensors send their own identification codes to the control unit, and the control unit allocates a CAN ID to each of the sensors after receiving the identification codes of the sensors, so that the identification code of each sensor is bound to the corresponding CAN ID respectively.

An insulated structure comprises a first panel and a second panel coupled to the first panel. The first and second panels define an insulating cavity therebetween. A port is defined by the second panel. The port is an opening into the insulating cavity. A connector is coupled to the second panel. A tube is coupled to the connector and extends parallel along the second panel.

A freezer for a food product, includes a housing having an internal space with a processing atmosphere for reducing a temperature of the food product; and a pressure balance apparatus in communication with the processing atmosphere to restrict atmosphere external to the freezer from reaching the internal space, the pressure balance apparatus comprising at least one sensor exposed to the processing atmosphere for generating a first signal indicating an amount of oxygen (O.sub.2) sensed at the internal space, and a blower disposed to direct a pressurized flow of the processing atmosphere to the internal space responsive to the first signal. A related method is also provided.

The present disclosure provides a drinking liquid cooling system comprising: a first cooler configured to cool drinking liquid; a second cooler configured to allow the drinking liquid from the first cooler to have a pre-defined temperature; and a drinking liquid guider configured to guide the drinking liquid via the first cooler and, then, via the second cooler and, then, to allow the drinking liquid to be discharged.

A dynamic multi-zone anti-sweat heating system may be used in a refrigerator to reduce moisture on various surfaces of the refrigerator. Moreover, in some instances, the determination of when moisture is present and/or absent from a surface may be made based at least in part on detection of the presence or absence of an elevated thermal load on the surface while a heater is activated.

A refrigeration facility such as a refrigeration container includes a refrigeration device cooling an interior of the refrigeration facility and including an evaporator allowing air inside the refrigeration facility to pass through. A condensate port serving as a corrosive gas detector is installed in a drain hose. The drain hose disposes condensate water from a drain pan, which collects condensate water generated by the evaporator. Detecting corrosive gas in the air inside the container by using a pH sensor to examine a pH value of condensate water in the drain port allows for reducing the risk of corrosion of components installed inside the container.

An appliance includes a metallic liner and an outer metallic wrapper. An insulating cavity is defined between the metallic liner and outer metallic wrapper. The appliance further includes a pressure sensing device disposed within the cavity. The pressure sensing device is located to detect a pressure status and transmit the pressure status through at least one of the metallic liner and outer metallic wrapper.

A refrigerator including a main body having a storage compartment, a door rotatably provided on the main body to open and close the storage compartment, and an automatic water supply device. The automatic water supply device includes a water supply case, a bucket detachably mounted on the water supply case, and a water level sensor provided to detect a water level in the bucket, and is configured to supply water to the bucket depending on the water level in the bucket. The door includes a dyke protruding from a rear surface of the door to form an accommodation space in which the water supply case is accommodated, and the water supply case is coupled to the dyke.

Selection of an optimum container that can ensure the quality of an article from a plurality of containers according to the type of the article, to calculate a rental unit price of one container to be commonly used at a time of delivering the article and at a time of storing the article at a delivery destination, and to calculate a rental fee of the container. A received-order management server calculates delivery date data and collection date data based on an article code and use date data received from a user terminal on a user side, and selects a container of a type corresponding to the article from plural kinds of containers based on the article code. The server then calculates a billing amount by multiplying a unit price by a rental period calculated based on a delivery completion notification and a collection completion notification received from a delivery unit.
