ShareVisualization of oil return in refrigeration plants with R12 and R134a during conversion.
Author(s) : JANNICK P., MEURER C.
Summary
The paper investigates all parameters involved in the oil/refrigerant behaviour, when converting a plant from R12 to R134a. Effects on heat transfer coefficient of several parameters are studied (oil/refrigerant miscibility, viscosity, oil return conditions).
