Hello every body
i working now on a shopping center of 28,000 sqm with a 1100 ref.ton air cooled chiller (Daiken Mcquay) and the chilled water network design to partial load from 14 in in dia. from the pump side down to 3/4 in end in the FCU , the problem is the designer wants to put a three way valve with full modulator to save energy when divergence is good and to make the pressure equal in all net pipes but thats expensive because we have over 535 PCS of FCU so please advice !!!
