Résumé

An experimental study has been carried out to analyse the thermal stability and to estimate the lifetime of refrigerating lubricants, PAG and POE oil are considered as test oils in the study. The viscosity of PAG and POE oil was measured by the vibration type viscometer while temperature is varied periodically. In order to estimate lifetime of PAG and POE oil with temperature, the viscosity was measured while the test temperature of oils was maintained continuously. The lifetime of oils is estimated as the decrease in viscosity change. The results indicate that the reduction rates of viscosity of PAG and POE oil were less than 5% after 510 temperature variation cycles.
