Field notes
The described plant combines two chiller types with shared chilled-water and condenser-water loops, pumps, and a cooling tower. Learners are meant to inspect components and practice procedures in that setting, with reference documents presented alongside the simulated equipment. The page also describes a timed format in which candidates complete one system before moving to the other, with no return to the first.
