(OP)
Hi every body,
we have heat exchanger needs chilled water with the following :
150 L/Hr
15-25 C , Inlet chilled water temperature
0.15 bar, Max inlet pressure
Can we use closed system with this very low allowble pressure? If We can't:
When we use an open system,does the pressure being produced by the pump will be more than 0.15 bar even that ,this pump is pumping to the atmosphere?

Our city water circuit (in summer) has high temperature around 30-35 C, I think we should use refrigeration device to get water temperature within the specified range.
About the throttling valve, I think the required valve should have very low flow cofficient depend on the pump discharge pressure. So, Is there a valve with this low Cv.
