MIT and Belimo Research on the Energy Valve; Confirms Improved Chilled Water Delta T Performance.

Proceeding from International District Energy Association (IDEA) Annual Campus Energy Conference.

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).
