Etude expérimentale de la dynamique d'une soupape automatique dans un compresseur à piston pour le froid transcritique au CO2.
Experimental investigation of the dynamics of a self-acting valve in a reciprocating compressor for transcritical CO2 refrigeration.
Résumé
The self-acting valve has a significant influence on the efficiency and reliability of the reciprocating compressor. The large density and high pressure difference through the valve cause serious bending and impact stresses in the valve and thus great challenges for the valve design. Experimental investigation of the valve dynamics are required to design a self-acting valve with high efficiency and long life span for the transcritical CO2 compressor. A semi-hermetic reciprocating compressor was developed for a CO2 refrigeration application, and a test system was incorporated into the compressor performance test rig, focusing on investigating the dynamics of the discharge valves. With the experimental results, the movement of the valve is described in detail for transcritical CO2 compressor, based on which the thermodynamic performance of the compressor is studied.
