Parametric study and experimental comparison of small hermetic refrigeration compressors using an advanced numerical simulation model

摘要

An advanced numericla simulation of the thermla and fluid-dyanmic behaviour of hermetic reciprocating compressors has bene develope dand recently improved to be used in the whole compressor domain.The domain is divided into fluid and solid contorl volumes.THe fluid flow modellating os based on the full integration of the one-dimensional and transient governign quatios of the flwo (continuity,momentum and energy) in all the fluid compressor zones.The solid thermal behaiour is based on heat global balances at each solid component.
