Title:
REFRIGERATING AIR CONDITIONING APPARATUS
Document Type and Number:
Japanese Patent JP2001317822
Kind Code:
A
Abstract:
To provide a refrigerating compressor which is operable stably over a long period of time using a refrigerant involving hydrofluorocarbon and freezer oil as a working medium.
There is formed a microcapsule 7 having the diameter of 5 μm or more and 50 μm or less in which an adding agent is contained in a working medium M for stabilizing refrigerating machine oil. Hereby, the microcapsule 7 flows followed by the working medium M, and the adding agent that is an included substance is discharged at need subsequently to demonstrate its function over a long period of time. Thereupon, the microcapsule 7 stays properly in a boundary lubrication area and is prevented from jamming in a capillary tube, etc.
