ABSTRACT:
Some constructions of the present invention provide a vent arrangement for a transport temperature control unit including a refrigeration circuit and being mountable on a transport container having a load space. The vent arrangement can include a duct communicating between the load space and atmosphere and extending across at least a portion of the refrigeration circuit, a shutter located along the duct and movable with respect to the duct between a closed position, in which the shutter prevents air flow through the duct, and a plurality of opened positions, and a sensor positioned adjacent to the shutter and operable to record shutter position data.
