A general purpose enclosure is provided. A general purpose enclosure for housing an internal unit and providing complete protection against an ingress of dust and water, comprising a first housing and a second housing. A plurality of cooling fins and one or more pressure ports along an exterior surface of the first housing and the second housing. One or more pressure ports comprising a pneumatic valve, pressure sensor cap and a vent membrane such that pressure venting, and pressure testing may be performed by the one or more pressure ports. A method of assembling a general purpose enclosure to an internal unit, comprising applying the first housing and the second housing to the internal unit such that the first housing and the second housing encompass the internal unit and fastening the first housing to the second house.

A transport refrigeration unit is configured to provide conditioned air to a refrigerated cargo space and includes: an AC battery pack configured to store and convert DC electricity to AC electricity and provide the AC electricity to power the transport refrigeration unit as three phase electrical power, the AC battery pack includes: a first phase group including a first plurality of battery modules, the first phase group being configured to provide the AC electricity in a first phase; a second phase group including a second plurality of battery modules, the second phase group being configured to provide the AC electricity in a second phase; and a third phase group including a third plurality of battery modules, the third phase group being configured to provide the AC electricity in a third phase. The first phase, the second phase, and the third phase are each shaped as a stair step sine wave.

A cold storage box is provided that allows individual confirmation that stored objects such as medicine, food, and beverages have been managed at an appropriate temperature. The cold storage box 1 includes: a storage part which can house stored objects; a lid part which covers an opening part of the storage part; and a cooling device which cools the storage part, and the cold storage box includes an RF tag provided for each of the stored objects and equipped with a temperature sensor and a control part which communicates with the RF tag at appropriate time intervals via an antenna part provided inside the storage part and stores ID information of the RF tag and temperature information sensed by the temperature sensor of the RF tag.

A food stand system with a plan view in the shape of an incomplete circle, with a flat top surface as a countertop, and a convex customer-facing surface. The stand contains a food preparation appliance having both cooking and refrigeration components. Sensors measure the appliance interior state, and provide data to an automated controller that controls appliance operation to prepare food for consumption.

An illustrative example embodiment of a transport refrigeration system includes an evaporator air management system having an evaporator heat exchanger and an air passage downstream of the evaporator heat exchanger. A two-stage fan assembly within the air passage includes a first fan stage having a first fan rotor, a first motor associated with the first fan rotor for selectively causing the first fan rotor to rotate in a first direction about a fan axis, a second fan stage having a second fan rotor in series with the first fan rotor, and a second motor associated with the second fan rotor for selectively causing the second fan to rotate in a second, opposite direction about the fan axis. The first and second fan stages draw air across the evaporator heat exchanger and through the air passage.

A mobile multizone refrigerator comprises a plurality of secure refrigerated storage zones each having a lockable door connected to a zone opening controller. The zone opening controller is connected by a network interface to a server capable of receiving and facilitating zone opening requests from the user devices of affiliated users of the storage zones. Upon receipt of an authenticated zone opening request, the server will transmit a zone opening instruction to the controller affiliated with the storage zone in question, resulting in its opening. The refrigerator is mobile allowing it to be moved into and between locations with ease.

A cool box includes: a first temperature holding chamberthat stores a first object to be cooled, a first cold insulator temperature, and a first indoor electricity generator that generates electricity on the basis of a difference between the temperatures of the first object to be cooledand the first cold insulator and holds the temperature of the first object to be cooled; a second temperature holding chamberthat stores a second object to be cooled, a second cold insulator temperature, and a second indoor electricity generatorthat generates electricity on the basis of a difference between the temperatures of the second object to be cooledand the second cold insulator and holds the temperature of the second object to be cooled; and an intra-chamber electricity generatorthat generates electricity on the basis of a difference between the temperatures of the first temperature holding chamberand the second temperature holding chamber .

An adapter for connecting a portable device to a control system of a transport refrigeration system includes a cable having a first end and a second end. A first connector is arranged at the first end of the cable and a second connector is arranged at the second end of the cable. The first connector is connectable to the portable device and the second connector is receivable within a port of the control system.

Systems and methods are provided for bimodal refrigeration, which uses a combination of mechanical refrigeration and phase change material (PCM) cells to provide cooling for one or more units of storage, such as freezers, coolers, storage or display cases, open cases (without doors), closed cases (with doors), rack systems (with compressors located remotely), self-contained refrigeration systems (with embedded compressors), in an optimal and efficient manner. In some embodiments, the systems and methods employ intelligent controls which may monitor and receive input for system conditions, time of day, and other conditions, and turn on/off the mechanical refrigeration as appropriate to provide for efficient and cost-effective use of energy.
