Performance of R407C with miscible and immiscible lubricants in unitary systems.

Author(s) : GOPALNARAYANAN S., ROLOTTI G. D.

Summary

Experiments were conducted in a 12.3 kW (3.5 T) split system heat pump to determine the oil return characteristics of R22/mineral oil as well as that of R407C with three different lubricants (polyol ester, mineral oil and alkylbenzene). Tests were conducted in both heating and cooling modes. The liquid level in the compressor was monitored with a video camera and recorded. The system capacity and the compressor power consumption were also measured.
