1,156,148. Refrigerators. CHEMETRON CORP. 27 Sept., 1966 [22 Oct., 1965], No. 43033/66. Heading F4H. Liquefied gas is evaporated in heat exchangers 31, 33 and the vapour is passed into a first network of longitudinally spaced ducts 30, 32, 40, 44 formed about the storage compartment 28 of an insulated container, the vapour then passing to a second network of ducts 45, 46, 49, 50, 53, 54 adjacent the external casing of the container before being vented to atmosphere. Headers 36, 37, 39, 41, 43, 47, 48, 51, 52, 55 interconnecting the ducts are provided. Heat exchangers 31, 33 are arranged to discharge into alternate ones of the ducts 32 in counterflow. The internal surfaces of the external casing may be lined with insulation and this in turn may be lined with material of good thermal conductivity. |
