In space conditioning vapor compression cycles often provide cooling and heating to the building all year around. The working fluid is a refrigerant and oil mixture. A small amount of lubricating oil is needed to lubricate and to seal the sliding parts of the compressors. In heat exchangers the oil in excess penalizes the heat transfer and increases the flow losses: both effects are highly undesired but yet unavoidable. This seminar provides an overview of the heat transfer and pressure drop characteristics of refrigerant and lubricant mixtures in heat exchangers. The seminar covers various applications from ammonia systems to HFO refrigerants. The seminar will assist engineers in the proper selection of the lubricant and refrigerant pairs.
