Here is a good idea for a frustrated HVAC person who likes to dabble with computer technology. It seems to me that now just about everyone (except me) uses a handheld device of some kind and is drawn to endless hours of using it analogous to drawing a moth to a flame to its screen.
Last month, we tested readers on commissioning three of the many automatic temperature control (ATC) sequences of operation associated with outdoor air ventilation, space cooling, and also no mechanical heating or cooling required.
When I have sat in on trade contractor field coordination meetings over the years, the prime contract (either a general contractor or construction manager) will have his project manager and/or mechanical and electrical coordinator facilitate these weekly meetings.
Sometimes, what seems like a need for more cooling capacity could be the need to take a hard look and fine-tune the existing chiller plant. With a hospital expansion coming up, the team on this UMass Memorial Health Care project avoided adding up to 120 tons of capacity with tactics that included attacking inefficiencies in piping, valves, cooling towers, and controls.
