Refrigerant retrofit in Sweden. Fields and laboratory studies.

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

Summary

Moisture and residual mineral oil plays an important role in the decomposition of the HFC refrigerant-ester oil mixture. Exactly which levels of contaminants that are acceptable are dependent of many parameters, such as: present alloys, type of oil and refrigerant and type and size of the unit and the compressor. Operational parameters, such as temperatures levels and operating time, also affect the system. This means that the tolerable level of contaminants varies from case to case. The experience and the material available from the past four years of intensive conversion work on the field, indicates that the levels accepted today, in the refrigeration industry, prevents increased wear and other problems.
