Development of a Test Rig for the Miscibility Analysis of Oil-Refrigerant Mixtures

Abstract
   Technological advancements have increased our reliance on mechanical systems, which often require cooling mechanisms due to their many integrated moving components. These systems utilize refrigeration cycles involving two crucial fluids: refrigerants and lubricating oil. Refrigerants transfer heat, providing the necessary cooling effect. However, refrigerants over the years have negatively impacted the environment. This study developed an oil-refrigerant testing rig to measure the density, viscosity, and miscibility of these mixtures. As technological advancement continues, the need to cool mechanical systems will rely on the development of sustainable refrigerants. The testing rig will play an important role in the advancing research on environmentally friendly refrigerants and their compatibility with lubricating oil, contributing to a sustainable future.
