The temperature of container borne cargo in a ship's hold is controlled by using a gas distribution chamber (8) having a number of outlets (22) for passing gas into respective containers (2) in the hold. A fan or other means is provided to propel gas from the hold to the gas distribution chamber, and means eg a refrigeration unit are provided for controlling the temperature of gas entering the containers. In operation, gas from the distribution chamber passes into and through the containers, thereby controlling the cargo temperature, and then escapes from the containers via outlets (26) into the hold to be re-circulated by the fan. Preferably, the outlets (22) and the corresponding container inlets (24) lack any means for forming a sealed connection; gas being blown from one through the other in use. The inlets (24) may be shaped venturi fashion to promote air flow. |
