Hi, I have a system containing two chillers piped in parallel, each with a dedicated constant speed pump. When the cooling load is less than 50%, only one chiller is working, and when the load increases the second chiller starts operating. The way to control the temperature is by a control valve located on a bypass pipe that connects the supply and return pipes. The percentage of opening the control valve is controlled by the water temperaure.
Which component should I put on the bypass to represent that control valve? I didn't find any. should I just use a bypass adiabatic pipe on the demand/supply side, and use a setpoint manager which will be responsible of controlling the flow through this bypass? And in that case how? I will appreciate your help on this configuration. Thank you!
