Abstract (en)

The object of the present invention is to provide equipment that has complete safety against leakage of refrigerants from pin holes produced on a compressor that is intended for refrigerating air conditioners using refrigerants that are heavier than air and flammable. A junction 5a of a hermetic container, where pin holes are most likely to be formed, is arranged to be located below a control box 28 which has the possibility of becoming a source of ignition. The mixture ratio between air and refrigerants that might leak from pin holes produced in the welded junction 5a and the like of a hermetic container 2 of a hermetic compressor 1 is prevented from reaching a ratio where ignition takes place inside of an air conditioner. As a result, a refrigerating air conditioner having complete safety is realized. <IMAGE>
