Principles of refrigerant circuiting with application to microchannel condenser. 1. Problem formulation and the effects of port diameter and port shape. 2. The pressure drop effect and the cross-flow heat exchanger effect.

Summary

The growing demand for compact heat exchangers has led to the development of new techniques. Recent advances in extrusion and brazing processes have catalyzed the development of microchannel heat exchangers. A need exists for systematic evaluation of the factors that influence refrigerant circuiting design and development of principles for use in refrigerant circuiting design. The authors formulate refrigerant circuiting design issues in terms of an optimization problem and examine the effects of tube diameter and tube shape on refrigerant circuiting design. The effect of refrigerant circuiting in a microchannel condenser and the extendability of the single-phase heat exchanger analysis are evaluated. Two new effects are introduced when considering condensation heat transfer: the pressure-drop effect and the cross-flow exchanger effect.
