Some models will state the type of oil originally included with the compressor. The Btu capacity is normally included, but, sometimes, instead of the Btu capacity, the model number will state the compressor’s motor horsepower or its displacement.
Many times, the application range of the compressor can be determined, which identifies if the compressor is designed for high-, medium-, or low-temperature application. Some model numbers will also include the type of refrigerant originally designed for the compressor. The physical characteristics of the compressor series, such as its footprint, body dimensions, and layout of its stub or service valve connections, which may be useful when determining if the universal component will fit onto the compressor. Listed here is some of the information that might be obtained from the nomenclature of a compressor’s model number: This is not a difficult task the information is usually readily available from the manufacturer in their service publications. The information contained in the model number will vary from manufacturer to manufacturer, so you will need to obtain the coding used for each of the different compressors you service. Every compressor manufacturer has its own nomenclature for its series of compressors.
Again, this can be a valuable aid for a technician when trying to select a replacement component. There is much information about a compressor that can be obtained from decoding its model number.
