The evaluation of PVE on lubricating and capillary tube blockage by actual machines.

[In Japanese. / En japonais.]

Author(s) : KAWAGUCHI Y., TAKAGI M., TOMINAGA S.

Summary

Polyvinylether (PVE) has been evaluated and chosen as a refrigeration oil for HFC air-conditioning systems. The paper reports the lubricating and anti-capillary tube restriction characteristics of PVE based on actual machine testing. The lubricating capacity PVE is better than that of POE because the EP agent works effectively and forms solidified film under boundary lubrication region. Anti-capillary restriction performance of PVE is superior to POE for the following reasons: there is no hydrolysis and no tribochemical reaction at sliding surfaces.
