Chilled water plant efficiency refers to the total electrical energy it takes to produce and distribute a ton (12,000 BTU) of cooling. System design, water quality, maintenance routines, cooling tower design, and cooling coil load all affect chiller water plant efficiency and the expense of operating the system.
This guide is focused on using data to evaluate the potential positive impacts of controlling chilled water coil differential temperature (ΔT) on overall chilled water plant efficiency.
