1.Cause estimation
Oil level change of the oil separator takes place when the compressor capacity to change
It is because the gas flow rate is changed
Propylene gas impact of the oil cooler shell side
2.Cause estimation of the oil pump is operated two
Oil cooler pressure loss is as large as 2kg/cm2
This propylene gas is also effected
on the design and the required flow is maintained,but can be difficult to maintain the flow rate is a mix of propylene gas and oil
