Abstract Inert gases are conveniently used for leak detection. Relative to CO2, majority of the inert gases are non-condensable. It is of great significance to
understand the effects of residual non-condensable gases on the performance of a refrigeration system. This paper investigates, both theoretically and
experimentally, on the impact of residual non-condensable gases on the performance of a carbon dioxide (CO2) evaporator and the system performance.
A theoretical analysis indicates that residual non-condensable gases can convert homogeneous nucleation into a heterogeneous nucleation process and
accelerate phase change, thus, reducing superheat or incipient boiling temperature. To investigate the… More >
