High Efficient CO2 trans-critical Reciprocating Compressor Part I: Valve plate and cylinder head 1 D flow optimization

摘要

In this article we will describe a new high efficient CO_2 trans-critical compressor architecture where valvestechnology choices will be detailed.A first compressor efficiency optimization step was done based on the following methodology:1. Experimental PV diagram analysis2. Valve plate design tool (lift, spring, ports optimization)The article will be completed by experimental validation of this initial step.
