摘要： PROBLEM TO BE SOLVED: To eliminate choking of a capillary constituting a refrigerant circuit and malfunction of the components thereof.
SOLUTION: Residual oil composed of ester oil, ore oil and alkyl benzene oil being used as a process oil at the part of a circuit component touching a fluid is set at 2 wt.ppm or below for lubricant and residual moisture is also set at 2 wt.ppm or below. Consequently, total oil content of refrigerating machine oil can be controlled to 2 vol.% or below and moisture content in the oil can be controlled to 150 ppm or below thus realizing a clean refrigerant circuit where decompositon of oil itself or refrigerating machine oil at the compressor structural section is suppressed.
