Improving the Delta T in New Buildings

Improving the Delta T in New Buildings

Delta T’s calculations are based on the maximum or minimum outside air temperatures depending on the location of the building. If the system has been, designed, sized, installed and commissioned correctly then the Delta T should be maintained at maximum design loads and at low loads. Typically, it is more difficult to maintain the Delta T at low loads simply because the equipment is sized for the maximum design load. At lower loads flows become less turbulent (laminar flow) through the unit affecting the heat transfer process.
