Claim:
1. A method of cooling a cargo in a cargo container comprising: flowing a refrigerant through a plurality of refrigerant tubes disposed in a roof cavity of the cargo container, the roof cavity defined by an outer roof panel and an inner roof panel spaced from the outer roof panel; transferring thermal energy from container air in the container to the refrigerant thereby cooling the container air; circulating the container air via natural convection toward the cargo disposed in an interior of the cargo container defined between the inner roof panel and a floor of the cargo container thereby cooling the cargo via thermal energy transfer to the container air; recirculating the container air toward the plurality of refrigerant tubes; and directing condensate toward a selected location in the cargo container; via: disposing the plurality of refrigerant tubes at an angle nonparallel to horizontal; and flowing the condensate toward the selected location via gravity.
