Heat transfer analysis of air-to-carbon dioxide two-phase heat absorption and supercritical heat rejection.

Author(s) : ROBINSON D. M., GROLL E. A.

Type of article: Article

Summary

Carbon dioxide is a fluid with a history of being used as a refrigerant that has recently been considered for certain applications that may take advantage of its unique thermophysical properties. The high volumetric heat capacity of carbon dioxide is a particular feature that could make a carbon-dioxide-based refrigerating/air-conditioning device appropriate for a weight or space-limited application. This study presents a comparison of heat-exchanger models of the heat absorption (evaporation) and heat rejection process for both carbon dioxide and R22 air-conditioning cycles.
