Screw Compressors- | Mathematical Modelling And Performance Calculation

The first screw compressor was patented in the 1930s by a Swedish engineer named Carl de Laval. However, it wasn't until the 1960s that screw compressors gained popularity, particularly in the refrigeration and air conditioning industries. The early designs were based on simple geometric models, which provided a rough estimate of the compressor's performance.
