[bldg-sim] Pump location



Title: specific energie in office buildings
Hello:
 
We've got data on lots of pumps...including the REJ building, where the whole physical plant was put up 2 stories in the air to reduce pumping power, and the cooling towers placed directly on top of the plant to further reduce pumping energy, or at least this was the design intent.

Subject: [bldg-sim] Pump location

I am looking for information (articles, research papers, case studies) on the effect of the location of the pump relative to a plate and frame heat exchanger in a closed piping system.  Some of the issues are (1) the vertical height of the piping system (1000’ to 2000’), how high can you go, (2) pumping thru HX, (3) pumping away from HX, (4) pump and HX located at bottom of system, (5) pump and HX at top of system, and (6) pump start up.  What are the issues when the HX is replaced with other equipment such as chillers and boilers?
