Hello everyone!
I have modeled water cooled packaged DX systems that are connected to a
cooling tower having a single-speed fan and pump. When I change the
single-speed fan and pump with variable speed drives as an EEM, the results
show a reduction in "Pumps & Aux." load as well as "Space Cooling" load. In
fact, sometimes the reduction in space cooling load seems to be greater
than "Pumps & Aux." load itself. Can anybody decipher what is the relation
of VSDs pump and fan of cooling tower with space cooling load?

Thanks
