Application du tube capillaire dans un système de conditionnement d'air au CO2.

The capillary tube application in a CO2 air-conditioning system.

Auteurs : BIALKO B., KROLICKI Z.

Résumé

This paper presents a non-adiabatic homogeneous model of carbon dioxide flowing through a capillary tube, where the carbon dioxide undergoes a phase change from supercritical fluid flow to subcritical two-phase flow. The model is based on the fundamental conservation equations of mass, momentum and energy. These equations are solved simultaneously through iterations. The in-tube flow can be divided into a single-phase region and a two-phase region. The extreme choked situation at the outlet is evaluated by local sonic velocity judgment. Relationships between gas pressure in the cooler, evaporating temperature, heat transfer to the ambient coefficient and other working parameters are presented and analysed in detail.
