What is the characteristic of an oil with low viscosity in refrigeration applications?

Low viscosity oils in refrigeration applications are typically less effective in ensuring proper lubrication within the system. While they may flow more easily, this can lead to insufficient lubrication of compressor parts, resulting in increased wear and tear, reduced efficiency, and a lower overall performance. Insufficient lubrication may cause components to operate under increased friction and heat, which can lead to a decline in operational efficiency over time.

Additionally, while low viscosity oils may provide some benefits in terms of heat transfer, the primary concern remains how well they can sustain the operation of the refrigeration unit without causing damage or increasing operational costs due to inefficiencies. Therefore, in many refrigeration scenarios, oils with the appropriate viscosity are crucial for maintaining efficiency and reliability.
