PURPOSE:To make parts for 50Hz common with the same for 60Hz and improve the efficiency of parts management by a method wherein the series of the compressors for the 50Hz specifications is enabled to be constituted by utilizing the compressors for the 60Hz specification commonly. CONSTITUTION:The refrigerating capacities B1, B2,... of the compressors 1, 2,... for the 60Hz specification are set substantially at the rate alpha of the refrigerating capacities in air-conditioning of 50Hz to 60Hz in electric source frequencies. In the 50Hz area, compressors 2', 3',... for 50Hz are constituted by utilizing the compressors 2b, 3b,... for the 60Hz specification without reconstructing them but utilizing motors 1a, 2a,... for the compressors 1, 2,..., which are having one rank lower capacities in the 60Hz series, instead of the motors 2a, 3a,.... The refrigerating capacities of the compressors 2', 3',... for the 50Hz specification become substantially equal to the same B1, B2,... of the compressor 1, 2,..., which are having one rank lower capacities than the compressors 2, 3... for the 60Hz specification. |
