<h1>New SION Issued for Hermetically Sealed Compressors Using R 22 Refrigerant: Input-Output Ratios Specified by Capacity</h1> The Standard Input-Output Norms (SION) for hermetically sealed compressors used in air conditioners with R 22 refrigerant gas. It specifies the required input materials and their proportions based on the compressor's capacity, measured in Kcal/hr. The components include CRNGO steel, copper wire, music wire, refrigeration oil, HR non-alloy steel sheets/coils, and EC grade aluminum ingots. The norms ensure that the imported goods are necessary for manufacturing the export product, with specific input-output ratios provided for each material depending on the compressor's capacity.
