Title:Alternative Refrigerants in Adiabatic Capillary Tubes
Author(s):Meyer, J.J.; Dunn, W.E.
Subject(s):stationary air conditioning system analysis
Abstract:This study examines the mass flow rate of refrigerants in adiabatic capillary tubes, with an emphasis on the nature of the metastable region for both single component refrigerants and mixtures. The metastable region of a capillary tube was found to be much more predictable than previously thought. A new and revealing data taking technique, which takes the history of the system into account, allowed for the discovery of a hysteresis effect in the mass flow rate as the level of inlet subcooling is increased and decreased. This finding may have a profound impact on the future of capillary tube data acquisition and modeling.
