Chilled Ceilings

with PICV control

Function

The room temperature is controlled by a controller connected to the PICV actuator. The control can either be modulating or On/Off depending on the system layout. On/Off control is often selected on passive chilled ceiling to avoid laminar flow which lowers the cool transfer from the water to the coil.
