Technical information

Volume flow control, Produktbeziehungen

  • Volume flow control

Functional description

VAV terminal units control the volume flow in a closed loop, i.e. measurement – comparison – control.

The volume flow rate is determined by measuring the differential pressure (effective pressure). For this purpose the VAV terminal unit is fitted with a differential pressure sensor.

The static differential pressure transducer transforms the effective pressure into a voltage signal. The volume flow rate actual value is hence available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal volume flow rate (Vnom).

The volume flow rate setpoint value comes from a higher-level controller (e.g. room temperature controller, air quality controller, central BMS) or from switch contacts. Variable volume flow control results in a value between Vmin and Vmax. It is possible to override the room temperature control, e.g. by a complete shut-off of the duct.

The controller compares the volume flow rate setpoint value to the actual value and controls the actuator accordingly if there is a difference.

The volume flow rate parameters Vmin and Vmax are set on potentiometers (VRP) or stored in the controller. Voltage ranges are factory stored in the controller. Changes on the customer's site can easily be carried out using a potentiometer, an adjustment device or a notebook with service tool.

Volume flow control

  • The volume flow controller works independent of the duct pressure
  • Differential pressure fluctuations do not result in permanent volume flow rate changes
  • To prevent the control from becoming unstable, a dead band is allowed within which the damper blade does not move.
  • The factory set volume flow rate parameters can be altered by the customer

Pressure control, MP bus/Analogue Δp, Analogue 2 – 10 V DC Δp, Analogue Δp (Gruner)

  • Pressure control
  • MP bus/Analogue Δp
  • Analogue 2 – 10 V DC Δp
  • Analogue Δp (Gruner)

Functional description

The static differental pressure transducer transforms the differential pressure into a voltage signal. The differential pressure actual value is available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal differential pressure (Δpnom).

The differential pressure setpoint value is either a constant value or it comes from a setpoint adjuster or from switch contacts.

The controller compares the differential pressure setpoint value to the actual value and controls the actuator accordingly.

The differential pressure parameters are set on a potentiometer (VRP-STP) or stored in the controller. Voltage ranges are factory stored in the controller. Changes on the customer's site can easily be carried out using a potentiometer, an adjustment device or a notebook with service tool.

Constant pressure control

  • The differential pressure controller works independent of the duct pressure
  • Pressure fluctuations do not result in permanent differential pressure changes
  • To prevent the control from becoming unstable, a dead band is allowed within which the damper blade does not move.
  • The factory set differential pressure parameters can be altered by the customer

Variable pressure control

  • Relays or switch contacts connected to the control signal input Y/Z can be used to achieve constant pressures ∆pmin and ∆pmax or to override various control settings.

Application

  • Electronic differential pressure controller VRP-M, combined with a static differential pressure transducer VFP-100 or VFP-600, as Universal controller
  • Variable or constant differential pressure control
  • The differential pressure is measured using the static measurement principle
  • Voltage range for the actual and setpoint value signals 0 – 10 V DC or 2 – 10 V DC
  • Separate inputs for override controls enable the centralised switching of groups of controllers
  • With MP bus interface: Up to eight VRP-M users can be addressed on an MP bus (LAN); Belimo-Interface UK24LON for LonWorks systems; UK24EIB for EIB systems; UK24MOD for Modbus systems; UK24BAC for BACnet; DDC controllers with MP bus interface can control the Universal controller via data transfer
  • When the MP bus interface is used, the analog 0 – 10 V or 2 – 10 V interface cannot be used at the same time.
  • The MP bus interface cannot be used with fast-running actuators

VRP-M

Constant pressure control

The differential pressure setpoint value as given in the order code is stored as Δpmin in the controller. The nominal differential pressure Δpnom is the reference unit.

To maximise the control accuracy, different pressure ranges with the corresponding nominal differential pressures are used. The correct range is factory set. It is possible to change Δpmin at a later stage but only within the factory set pressure range.

Variable pressure control

A setpoint value signal enables variable pressure control. The control range is Δpmin to Δpmax, based on the setpoint value signal 0 (2) – 10 V.

VRP-STP

Constant pressure control

The differential pressure setpoint value that has been ordered (order code) is factory set as Δp in the controller. The nominal differential pressure Δpnom is the reference unit.

To maximise the control accuracy, different pressure ranges with the corresponding nominal differential pressures are used. The correct range is factory set. It is possible to change Δp at a later stage but only within the factory set pressure range.

Variable pressure control

A setpoint value signal enables variable pressure control. The control range is from Δplimit to Δpmax.
