Résumé

An analysis of the influence of oil atomization in the cylinder of a reciprocating compressor using ammonia as a refrigerant is presented. During compression, oil atomization enhances heat removal from the refrigerant vapour and, as a consequence, an overall temperature decrease is brought about in the compressor. The cooling effect of the compression process allows a reduction of losses associated with compression inefficiency. The simulation methodology adopted in the analysis is based on an integral control volume formulation for mass and energy conservation. Computational fluid dynamics simulations using commercial software were also performed to support some required data for the theoretical analysis. The effect of oil atomization on compression performance is presented and discussed based on oil injection parameters, such as nozzle positioning, oil temperature and flow rate.
