Controlled atmosphere storage chamber
First Claim
1. A controlled atmosphere storage chamber including:
- (i) means for generating cooled and pressurised air located within or adjacent the chamber;
(ii) a single air supply duct associated with the generating means for circulating the cooled and pressurised air throughout the chamber wherein the supply duct extends substantially the length of the chamber and has an unrestricted air flow passage which has a transverse dimension that tapers progressively inwardly throughout its length towards an end remote from the generating means;
(iii) air outlet means associated with the supply duct, which air outlet means extends substantially the length of the supply duct;
(iv) at least one elongate hollow storage member having at least one heat source located closely adjacent thereto wherein the interior of the storage member functions as a return duct for return of heat laden air to the generating means, the return duct extending substantially the length of the chamber and having an unrestricted air flow passage which has a transverse dimension that tapers progressively inwardly throughout its length towards an end remote from the generating means; and
(v) air inlet means associated with the return duct extending substantially the length of the return duct.

Abstract
A controlled atmosphere storage chamber (22) including:
(i) means (34) for generating cooled and pressurised air located within or adjacent the chamber such as an airconditioner;
(ii) one or more air supply ducts (28) associated with the generating means for circulating said cooled and pressurized air throughout the chamber (22) wherein the or each supply duct (28) extends substantially the length of the chamber (22) and has an unrestricted air flow passage which has a transverse dimension or width that tapers progressively inwardly throughout its length towards an end remote from the generating means (34);
(iii) air outlet means (51, 61, 62) associated with the or each supply duct (28) which air outlet means (51, 61, 62) extends substantially the length of the or each supply duct (28);
(iv) one or more elongate hollow storage members (23) having one or more heat sources (27) located closely adjacent thereto wherein the interior of the or each storage member functions as a return duct (29) for return of heat laden air to the generating means (34) characterized in that the or each return duct (29) extends substantially the length of the chamber (22) and has an unrestricted air flow passage which has a transverse dimension or width that tapers progressively outwardly throughout its length towards an end remote (59) from the generation means (34); and
(v) air inlet means (52, 54) associated with the or each return duct (29) extending substantially the length of the or each return duct (29).

20. A controlled atmosphere storage chamber including:
-
(i) means for generating cooled and pressurised air located within or adjacent the chamber; (ii) at least one air supply duct associated with the generating means for circulating the cooled and pressurised air throughout the chamber wherein the supply duct extends substantially the length of the chamber and has an unrestricted air flow passage which has a transverse dimension that tapers progressively inwardly throughout its length towards an end remote from the generating means, the supply duct having a plurality of baffles on opposite inner sides of progressively increasing dimensions transverse to the length of the supply duct from an end adjacent the generation means to an end remote from the generation means to provide a tapered unrestricted air flow passage which has a transverse dimension that tapers progressively inwardly throughout its length towards the remote end; (iii) air outlet means associated with the supply duct, which air outlet means extends substantially the length of the supply duct; (iv) at least one elongate hollow storage member having at least one heat source located closely adjacent thereto wherein the interior of the storage member functions as a return duct for return of heat laden air to the generating means, the return duct extending substantially the length of the chamber and having an unrestricted air flow passage which has a transverse dimension that tapers progressively inwardly throughout its length towards an end remote from the generation means; and (v) air inlet means associated with the return duct extending substantially the length of the return duct.
