The pressurized room with thermal power application is a separate application type. Each application type can also combine a radiant/chilled ceiling or radiator application. The image below provides an overview of the application type with all possible components that can be configured for a pressurized room with thermal power application.
The thermal power control function is a room temperature control algorithm that includes a PID feedback controller and heat transfer calculations. It controls the room temperature by adjusting the supply flow rate and supply flow temperature. When the supply flow changes due to pressurization or ventilation demands, this function adjusts the supply air temperature to balance the heat flow to the room.
