Lubricant, Low GWP refrigerant, Natural refrigerant, HC
Lubricant selection is based on several lubricant properties to satisfied compressor and system reliability, longevity and energy efficiency performances. The use of non-miscible or low soluble lubricant can bring some technical advantage for the compressor and the system. This paper presents investigations results on low GWP refrigerant alternatives for light commercial and commercial applications. The work also targets the reduction refrigerant charge associated with the compressor characteristics.
