A cooling apparatus includes: a water circuit; a ventilation heat exchanger that heats cooling water by heat exchange with air discharged to outside; a motor generator cooling unit; a motor bypass circuit that bypasses the motor generator cooling unit; and a flow rate control unit. When a temperature of the cooling water flowing between the ventilation heat exchanger and a motor flow rate controller is lower than or equal to a temperature of oil circulating inside the motor generator, the flow rate control unit increases a flow rate of the cooling water that flows from the ventilation heat exchanger into the motor bypass circuit.

Pallet racking systems are designed to quickly freeze items using thermal transfer by moving air through palletized products. Air is pulled through the palletized product to a negative air plenum behind the pallet rack. Back panels of the pallet racks provide variable-height airflow by use of louvers which are individually pressed open by the palletized product to accommodate differing product heights. The panels allow more efficient system operation with any number of rack positions filled.

A blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

A shipping container is provided and includes a structural frame defining an interior, a transport refrigeration unit (TRU) and a control system. The TRU includes an inlet through which air is drawn from a lower region of the interior, a refrigeration unit configured to cool the air drawn from the lower region of the interior through the inlet and an outlet through which air cooled by the refrigeration unit is exhausted toward an upper region of the interior. The control system is configured to control an exhaustion of the air cooled by the refrigeration unit toward the upper region of the interior to maintain a predefined environmental condition within the interior.

An augmented heat transfer system can be used to control the humidity of adjacent conditioned spaces by selectively absorbing latent heat energy from a relatively warm space, such as a loading dock, and discharging this energy in the form of sensible heat to an adjacent relatively cold space, such as a freezer served by the loading dock. This transfer of sensible heat energy into the cold space induces a vapor compression system to remove sufficient moisture from the cold space to avoid uncontrolled precipitation. At the same time, the process of removing moisture/latent heat from the warm space can also be used to reduce humidity in the warm space via condensation on a cold evaporator. Therefore, in operations where the warm space and the cold space are both nominally sealed from ambient air, such as an indoor loading dock serving a freezer, the augmented heat transfer system can eliminate uncontrolled precipitation in the freezer while also mitigating moisture ingress to the freezer from the dock space.

A picnic cooler that includes a food compartment, a gas tank compartment, an off/on electric spigot, a first sealing rings with a first apertures a second sealing ring with a second aperture, and two cooling apparatuses. The cooling apparatus includes a twisting piping system and an upper metallic plate that serves as the bottom of the food compartment. The ratio between the diameter of the second aperture and the diameter of the first aperture is between 1.8 to 2.2 and the ratio between the inner surface area of the food compartment and the outer surface area of the first and second piping systems is between 9 to 17.
