A blast cell system is disclosed that includes a plurality of bays that are spaced across the blast cell, arranged to hold items to be cooled, wherein each bay is separated from each other bay so as to prevent cross-flow of air from one bay to another bay; a plurality of louvers, each covering a different bay of the plurality of bays; one or more flow sensors, temperature sensors, or both positioned to sense conditions for each of the plurality of bays; and a controller programmed to modulate open-closed positions of each of the plurality of louvers separately from others of the plurality of louvers, so as to allow different volumes of cooling air to flow through each respective bay.

A delivery compartment comprising one or more cavities and one or more doors, such that access to each of the cavities is granted separately. The delivery compartment may include a lock preventing access to the one or more cavities unless authorization is obtained. The delivery compartment may be integrated into a wall, or other structure, associated with a building, such as a residential home or business. The delivery compartment may be built into or otherwise configured into a door for the building such that certain panels allow access to the one or more cavities for delivery of goods while other panels allow access to an interior space of the building itself. The delivery compartment may include environmental control capabilities for one or more of its cavities.

Disclosed herein is a multi-temperature-region ice-temperature fresh keeping storehouse and a fresh keeping method for bergamot pears that includes a precooling region, a feeding and discharging channel, a cooling region, an ice temperature detection device, a grading device, a conveyer belt control device, an automatic storage device, and a temperature rise and fall buffering channel. The cooling region includes four freezers, with temperatures ranging from 0 C.-3 C. The four freezers are connected level by level according to a temperature reduction rule. The present disclosure implements multi-temperature-region graded storage of bergamot pears according to the value of an ice point temperature of the bergamot pears, so that they are always stored close to the ice point temperature without freezing, thereby preventing freeze injury, and prolonging shelf life.

A refrigerator includes a cabinet that defines a freezing compartment and a refrigerating compartment, and an evaporator installed in the freezing compartment. The evaporator includes: an evaporator case that defines a food storage space formed therein; a cooling tube located at the evaporator case in a predetermined pattern and configured to receive a coolant; and a sheath heater disposed outside of the evaporator case to be adjacent to at least one surface of the evaporator case, the sheath heater being configured to generate heat such that heat for defrosting is transferred to the evaporator case. The sheath heater reduces the defrosting time to maintain the freshness of food, increases the cooling efficiency, and reduces power consumption. The defrosting efficiency by the sheath heater is improved by a reflection member, and an inflow of heat, generated when defrosting, into the refrigerating compartment is reduced by a heat insulation member.

Disclosed is a refrigerator having a first storage chamber, a second storage chamber located below the first storage chamber, an ice maker configured to make ice pieces, an ice bucket configured to store the ice pieces made in the ice maker and a middle wall partitioning inside space of the refrigerator into the first storage chamber and the second storage chamber and including a base portion and a stepped portion located higher than the base portion to form ice-making space, wherein at least one portion of the ice maker and at least one portion of the ice bucket are accommodated in the ice-making space. With this structure, the space for actual use of the first storage chamber can be increased.

A cold-shed may be deployed in areas with little or no electrical infrastructure in order to provide a cold storage area for perishable goods including agricultural, dairy products, medicines, vaccines, etc. A wireless communication device may be installed in the cold-shed to allow remote management, access control, and monitoring of the cold-shed devices, including cooling units, solar power cells, batteries, power conditioners, and a variety of sensors to determine internal and external temperatures, door positions, and other information. A mobile device configured to communicate with the wireless communication device may receive information and updates via cellular networks or text messaging. The mobile device may also be used to change temperature settings, lock and unlock doors, conduct inventory management and auditing, and make other changes. The corresponding application allows an owner to manage and monitor many cold-sheds from a single mobile device.
