The invention is directed to regulating the conditioned space of an environment-controlled transport unit by identifying the product being conveyed as cargo in the conditioned space of a transport unit. A user can identify the cargo by selecting it from a menu of cargo identifiers. Once the cargo is identified, an environment control system retrieves from memory environment-control parameters as a function of the identified cargo, and regulates the environment of the conditioned space based upon the environment-control parameters.

Environment-controlled transport unit

A removable modular duct system for conducting air in a temperature-controlled cargo container. Temperature-controlled air produced and propelled by a refrigeration unit, is conducted along the modular duct system by one or more duct sections and a transition section that conducts air from the refrigeration unit to the duct sections. The air may be discharged laterally via lateral discharge openings in the duct sections. An end section may be coupled to the duct sections to discharge air at the end of the duct system.

Duct system for temperature-controlled cargo containers

An air return bulkhead comprising a base; a return air duct extending outward from the base, the base and air duct defining a bulkhead return air chamber, the duct comprising a first wall, a second wall, a third wall, a fourth wall, and a fifth wall joining the other walls; at least one return air inlet notch formed in the air duct fourth and fifth walls; and means for producing turbulent return air flow through the return air chamber, said means located downstream from the at least one inlet notch. The bulkhead further includes air dam positioning means on the first and second walls. Individual air dam members are slid in the positioning means to be removably mounted along the bulkhead.

Air return bulkhead for temperature controlled trailers

A dual use kit of structural members, and method of using the kit to perform different functions during shipment and use of a transport refrigeration unit. Structural members of the kit initially form a shipping crate for a transport refrigeration unit, for protecting the transport refrigeration unit during shipment from a manufacturer to a user. The transport refrigeration unit is mounted on the outer surface of a predetermined trailer wall such that the return air plenum extends into a conditioned space defined by the trailer. Structural members of the shipping crate are convertible by the user to form an air return bulkhead adjacent to an inner surface of the predetermined wall of a trailer, to direct trailer air into the return air plenum of the transport refrigeration unit.
