The transition to lower global warming potential refrigerants such as HFOs, carbon dioxide and propane creates a number of design and operational challenges to compressor and system builders. Lubrication is one of the fundamental issues that must be addressed for any refrigerant change. This seminar presents examples of the lubrication challenges faced by the industry from three different perspectives; the compressor/system builder, the refrigerant manufacturer and the lubricant manufacturer. Examples are presented of strategies used to ensure that the transition to low GWP refrigerants results in refrigeration systems with the best possible properties of energy efficiency and long term reliability.
