MIT and Belimo Research on the Energy Valve; Confirms Improved Chilled Water Delta T Performance.
MIT and Belimo conducted experiments in 2011 on six air handling units at MIT’s Hayden Library to determine relative effectiveness of several strategies to improve chilled water delta T performance. Using original control valves versus Belimo Energy Valve with smart actuator, and controlling air temperature versus chilled water delta-T, delta T was measured for various combinations of control strategies. Results presented in this joint MIT and Belimo presentation (and paper).[youtube]http://www.youtube.com/watch?v=jtAF-9Jfd7o[/youtube]
