Hi All,
I am looking for some advice on a chilled water piping layout , to connect a trane RTAB chiller (cooling capacity 269kW) to an air handling unit for a cleanroom with a cooling coil of 106KW. The room is 27 metres x8 metres x 3 metres high.
I have been told that a buffer tank of at least 2000litres should be installed with the circulation pump sucking from the tank pushing the water through the chiller evaporator and from the evaporator to the air handler cooling coil.

The chiller, pump and tank are on the ground and the ahu is on the first floor upstairs. I really need to know the correct layout to connect all this together and what valves, fittings ,test points, and accesories should be fitted ( and where) in the system .
A diverter valve is already fitted to the cooling coil which will allow the chilled water bypass the coil when the room is at the set point temperature. The ahu is all that the chiller is cooling for the moment.
Thanks.
