Abstract

865,148. Refrigerators. HUSSMANN REFRIGERATOR CO. Feb. 9, 1959 [Feb. 10, 1958], No. 4432/59. Class 29 A show case having an open front and a low front wall 12 comprises inner and outer cabinets defining flues 20, 18, 22 and a top compartment 26 containing an evaporator 37 and fan 33 which produces a curtain of cold air across the front 39 between apertures 31 at the front of compartment 26 and apertures 38 at the top of flue 20, the air in the display space being cooled and circulated by further means. A receptacle 55 is mounted behind the front wall being spaced therefrom by a duct 43 communicating at its lower end with a space 41 containing evaporator 48 and fan 52. The fan draws air through apertures 44 at the top of duct 43 and through evaporator 48 and forces it through evaporators 53 behind receptacle 55. Part of the cold air then flows forwards in passage 62 through apertures 67 to cool the receptacle contents and return to apertures 44. The rest of the cold air passes behind a plate 59 carrying two angularly adjustable shelves 57, 58, some air flowing through apertures 71, 72 to cool the goods on the shelf. Some air also flows across the top of the display space in passage 84 and issues from apertures 86, 87. The cold air issuing from these apertures and from beneath the shelves flows to apertures 44 to establish an inner air curtain and to tend to support the air curtain between apertures 31, 38. Lights 90, price label holders 91 and defrosting heaters are provided. Specification 865,147 is referred to.
