REFRIGERATING CONTAINER

摘要

A refrigerated cargo container having a refrigeration unit 74 of variable capacity and an adjustable null band of temperatures over which it is inoperative is controlled by the lower temperature sensed by two temperature sensors positioned in the airflow to and from the cargo space. The unit 74 is fitted to an end wall of the container and separated from the cargo space by folding partition doors 70. Cooling air enters the cargo space through a slotted floor and leaves through an outlet above the doors 70 and immediately below the ceiling. The outlet is fitted with a grille 77 which avoids cavities in which unhygenic residues can build up. Fresh air is admitted to the container and stale air vented through manually adjustable valves which include perforated screens to meet customs' requirements.
