A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bays. An air seal is formed at the periphery of each opening by resiliently flexible side seals and a top seal to form a highly airtight interface between the pallet assembly and the adjacent airflow opening. When a pressure differential is developed between the chamber and the pallet bay, air is efficiently drawn substantially exclusively through the pallet assemblies with minimal leakage. The flexible sealing arrangement accommodates pallet assemblies with unevenly stacked rows of cases without significant loss of system efficiency.

A combination light and pressure relief vent is disclosed which includes a housing, a valve assembly, and a light assembly. The housing include a multi-radial positionable valve body, port tube, and an outside louver. The valve assembly includes a low positive pressure exhaust valve, a high positive pressure exhaust valve, a low negative pressure intake valve, and a high negative pressure intake valve. The light assembly includes a heat sink casing which defines a heat chamber and which includes a projection extending into the heat chamber. The casing is coupled to an LED module wherein heat generated by the LED module is transferred through the casing to the heat chamber to warm the valve assembly.

The present disclosure discloses a refrigeration mechanism and a cold storage warehouse. The refrigeration mechanism includes a compressor, configured to compress a refrigerant, so that the refrigerant flows in a pipeline; a condenser, configured to absorb heat of the refrigerant conveyed by the compressor, so that the gasified refrigerant becomes a liquid; an expansion valve, configured to perform throttling and pressure reduction to the liquid refrigerant; an evaporator, configured to exchange heat with outside air by using the refrigerant to implement refrigeration; and a driving component. The driving component includes an external combustion engine for driving the compressor and a material supply mechanism for providing fuel for the external combustion engine. Therefore, use of the electrical energy is reduced and the cost is reduced.

Air handling system for a climate control system in a housing that includes at least a delimited space with controlled environment, CE space. The air handling system includes an air handling unit, AHU, a pipe system and a perforated plate assembly. The pipe system includes a branched tree-like structure of conduits, that branches in the direction from the air handling unit towards the perforated plate assembly for homogenous distribution of air over the perforated plate assembly such that the air flow through the perforated plate assembly into the CE space is an air flow under laminar flow conditions. Also, a climate system for climate control in such a delimited space, a modular unit including such a delimited space and such a climate system, and an assembly of modular units.

A combination light and pressure relief vent (10) is disclosed which includes a housing (11), a valve assembly (12), and a light assembly (13). The housing include a valve body (16), port tube (17), and an outside louver (18). The valve assembly includes a low positive pressure exhaust valve (57), a high positive pressure exhaust valve (59), a low negative pressure intake valve (61), and a high negative pressure intake valve (62). The light assembly includes a heat sink casing (68) which defines a heat chamber (37) and which includes a projection (80) extending into the heat chamber. The casing is coupled to an LED module (57) wherein heat generated by the LED module is transferred through the casing to the heat chamber to warm the valve assembly.

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.

A ventilation system comprises a plurality of axial fan units, each having at least one axial fan having a rotational axis generally parallel to a downstream flow caused by the axial fan, and at least one grill positioned adjacent to the at least one axial fan in a downstream flow path of the axial fan unit, the at least one grill directing an air flow of the axial fan. At least a first series of the plurality of axial fan units is adapted to be positioned at a top of a plenum arrangement extending from a bottom front of a refrigerated enclosure, to a rear back of the refrigerated enclosure, said top being at a top of the rear back. At least a second series of the plurality of axial fan units is adapted to be positioned above an area to cool and oriented to project its downstream flow in a downward direction to direct its downstream flow to said area to cool. The first series of the plurality of axial fan units is oriented to project its downstream flow in an upward direction toward the second series of the plurality of axial fan units such that the first series is adapted to direct air from the plenum arrangement to the second series.

A multiple temperature automated storage system includes a rack with multiple levels of shelves defining item storage positions, an aisle at each level, and a plurality of shuttles adapted to operate in the aisles for storing items to and retrieving items from the storage positions. A thermally insulated enclosure encloses some of the levels of the rack to define a low temperature zone with the remaining levels of the rack defining a higher temperature zone. A method of storing items at two different temperatures in a common automated storage system includes having a first portion of the automated storage system enclosed in a thermally insulated enclosure and a second portion of the automated storage system outside of the thermally insulated enclosure. A lift is provided in the second portion for supplying items to and retrieving items from both of the first and second portions, without entering the first portion.

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 cooling system includes a radiator, a compressor that compresses a refrigerant to send the refrigerant to the radiator, and a blower that sends out an airflow suctioned from an intake port that is directed to a first direction from an exhaust port to a second direction by a rotation of an impeller around a rotation axis extending in the first direction. The first direction is parallel or substantially parallel to a direction normal to an installation surface on which the compressor is installed. The second direction is orthogonal or substantially orthogonal to the first direction. The radiator is in the first direction relative to the blower. The compressor is in the second direction relative to the radiator and the blower.
