Calculations for load distribution
Load distribution is calculated according to the following flow.
Note
y
“f” indicates a function calculation.
For example, “Operational performance rate D=f (SH, SC)” means that the operational performance rate is calculated using “Super heat SH”
and “Sub cool SC”.
