Study of capillary tubes in a transcritical CO2 refrigeration system.

Author(s) : MADSEN K. B., POULSEN C. S., WIESENFARTH M.

Summary

Capillary tubes have been used in refrigeration systems for many years, but not with a transcritical CO2 system. In this article, the effects of capillary tubes in a transcritical CO2 refrigeration system have been investigated experimentally and theoretically. Different types of capillary tubes with different lengths (0.5-4 m) and diameters (1-2 mm) have been tested. The result of this work is a static model, which is used in the further work to make a simulation model (static) of a complete refrigeration system. The model is based on Friedel's and Colebrook's pressure drop correlations.
