Thermal Mapping Of Hermetically Sealed Compressors Using Computational Fluid Dynamics Technique

Abstract

The complex fluid flow and heat transfer phenomena in hermetic compressors is very difficult to analyze theoretically because of the assumptions made while solving the problem and insufficient understanding of the physics involved.There is a need to thoroughly understand such phenomena to target the efficiency improvements of the compressor to meet current high EER requirements.This paper deals with the use of Computational Fluid Dynamics (CFD), a highly sophisticated numerical technique based on Finite Control Volume formulation, to analyze the entire compressor domain.
