Amélioration du rendement des compresseurs à piston grâce à l'injection liquide.

Efficiency improvement of the reciprocating compressors with liquid injection.

Résumé

In terms of qualification of alternative refrigerants, like R407F, high discharge temperatures require additional cooling, typically through the injection of liquid refrigerant, to perform reliably in all applications. The addition of the liquid to the discharge (cylinder heads) creates an inherent instability in the conditions and a loss in compressor performance. This study demonstrates how Demand Cooling (liquid injection) can be optimized through both controller logic and system design to improve these inherent drawbacks of adding liquid. Through proper controller logic and system design the pressure fluctuations can be reduced to create a more stable refrigeration system. Additionally, the quantity of liquid injected can be minimized to better balance the need for cooling and the impact on efficiency.
