Funktion blocks - room ventilation engineering

By using the controls a complex installation can be programmed through simple mouse clicks.

The function blocks for the room ventilation engineering are:

• Release of control and regulation of a room ventilation

• Calculation of enthalpy from moisture and temperature

• Controlling and regulation of circular network system
• Controlling and regulation of controllable flaps
• Controlling and regulation of cross-flow heat exchangers with gate valve
• Controlling and regulation of a calorific wheel

• 3.1 Controlling of the flaps
• 3.2 Hygiene circuit for outside air filters

• PWW - preheater without pump(s), with antifreeze (air and /or water related) 4.2 PWW - preheater with 1 to N pumps, with antifreeze (air and /or water related) 4.3 PWW - sequential heater without pumps
• PWW - sequential heater with pumps
• Electric air heater (graded), with safety devices
• Electric air heater (discrete), without safety devices
• Electric air heater (continuous), safety devices
• Electric air heater (continuous), without safety devices
