A model to predict R134a refrigerant leakage through the radial clearance of rolling piston compressors
(Elsevier B.V., 2012-12-01)
In this paper a non-isothermal two-phase model for oil-R134a refrigerant mixture flow is presented to predict the R134a leakage through the radial clearance of rolling piston compressors. The flow is divided in a liquid ...

Análise e retrofit com uso de hidrocarbonetos em substituição ao CFC R-12
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia MecânicaUTFPR, 2014)
In face of a device about to be scrapped, there is the idea to keep it in operation. For this, a commercial alternative that will cease to exist soon or a natural fluid developed in the last century. This study came to ...
