What is the viscosity of most oils used in refrigeration systems?

The viscosity of most oils used in refrigeration systems is typically around 100 centistokes. This viscosity level is important because it ensures proper lubrication within the compressor and other components of the refrigeration system. A viscosity of 100 centistokes offers a good balance between fluidity and film strength, allowing the oil to flow easily while still providing adequate protection against wear and tear.

In refrigeration systems, oil is crucial for maintaining efficiency and prolonging the lifespan of the equipment. Oils that are either too viscous or too thin may either hamper circulation or fail to provide sufficient lubrication, leading to potential breakdowns or inefficient operation. This is why the viscosity of 100 centistokes is often preferred in such applications. It strikes a compromise that supports effective lubrication, thermal conductivity, and overall system performance in various operational conditions.
