Abstract
724,866. Refrigerators. SOC. D'ETUDES TECHNIQUES INDUSTRIELLES ET FRIGORIFIQUES, S. E. T. I. F. June 22, 1953 [Aug. 6, 1952], No. 17298/53. Class 29. A. refrigerated chamber for storage is cooled normally by air circulated by a fan over a refrigerated unit and over the exterior of the chamber and, when extra cooling is required, part of the air is diverted to flow through the chamber. As shown in Fig. 2, the air circulates in ducts around the chamber and enters a duct 11 extending along one top corner of the chamber. The air then passes down ducts 4 ... 6 which also pass under the floor of the chamber and up the other side wall to enter a discharge duct 12 extending along the other top corner. Auxiliary ducts 13 ... 15 join the ducts 11, 12 and cool the ceiling of the chamber. Ducts 11, 12 are subdivided into channels one feeding each duct 4 ... 6 and so dimensioned as to supply equal quantities of air. When further cooling is required the supply of air is increased either by speeding up the fan or by throwing in further fans and the increased pressure opens valves 9, 10 in each of ducts 41 ... 61 to admit the air to the chamber. The air re-enters the ascending parts of the ducts by similar automatic valves. the ducts may be throttled downstream of the valves 9, 10. In a modification, the top ducts 13 ... 15 are dispensed with and the ducts 11, 12 are constituted by a duct extending over the whole of the ceiling and divided by a longitudinal partition. The valves 9, 10 comprise, (Fig. 6), a flap 46 pivoted to the chamber wall 31 and so counterweighted at 49 as to be slightly open (dotted line position) when the fan is not running. When the fan runs at normal speed, the valve closes and, when it runs at a higher speed, the valve moves to the position shown to admit air to the chamber. Detailed description of the application of the system of ducts shown in Fig. 2 to a chamber is given with reference to Figs. 3 to 5 (not shown).
