CFC and HCFC refrigerants retrofit: experiences and results.

Author(s) : HERBE L., LUNDQVIST P.

Type of article: Article, IJR article

Summary

The paper discusses levels of acid, moisture and residual mineral oil in converted refrigerant and heat pump plants. The work has been concentrated in three main areas: current retrofit practice, database of results from laboratory analysis of oil samples from converted plants and lab tests of combinations of R134a, ester oil, residual R12, residual mineral oil and moisture. The current retrofit practice study shows that most commonly used methods are satisfying as far as the moisture level is kept low. A comparison with the database study shows that measured values are at a level with the target values, given by the refrigeration companies. As a complement, sealed tube tests have been initiated in order to further clarify the effect of different combinations of contaminants.
