3.5 COMPRESSOR LUBRICATION/COOLING SYSTEM
The cooling system consists of a fan, variable speed fan motor, finned-tube radiator-type fluid cooler, &
thermovalve to accelerate warm-up, a full-flow filter, a drain valve and interconnecting tubing.
Pressure in the oil separation tank utilizes air pressure over oil which causes the lubricoolant to flow from
this region of relatively high pressure through the system to an area of lower pressure at the compressor
unit. Fluid flows from the oil separation tank to the cooler; from the cooler to the filter, and from the filter to
the compressor. During cold starts, the thermovalve is open allowing the fluid to by-pass the oil cooler
and go directly to the filter. While warming up, a gradual change occurs where the fluid flow is split -
partial flows being shared by both the oil cooler and thermovalve. When fully warmed up, fan motor will
operate at a speed to control the sensed compressor discharge temperature.
The fluid filter is of the spin-on replacement element type. The element should be changed in accordance
with the Maintenance Schedule.
