Author(s) : MORIMOTO O., KASAI T., KOGE H., et al.

Summary

This system is a new refrigerant (R407C) system for replacement of the outdoor unit and indoor units while using existing R22 refrigerant piping. In the test run, the mineral oil in the pipes used is removed by gas-liquid two-phase refrigerant flow. Low viscosity mineral oil is used to reduce the viscosity of the mineral oil remaining in the pipe. The replacement system has a high efficiency.
