Actual issue Excessive condenser pressure for trane chiller
No change in pump or piping lines.
There are two chillers of same capacity, but there is an issue that the CHW return to the evaporator coil for both chillers are at different temperature.
And the chiller that trips (say CH-2) has evaporator entering temp 12degreeC & is always running at 115-120 % Full load amps.
While the othre one (CH-1)has evaporator entering temp 6.5degreeC & is always running at 30-40% Full load amps.
The chiller that trips (CH-2)has condenser water inlet / outlet temp of 34 /41degee C( desing is 34 / 39.5 )
other chiller (CH-1) has condenser water inlet / outlet temp of 34 /37degee C( desing is 34 / 39.5 )
