Next generation of VAV
The demand for VAV systems in modern construction is increasing and with good reason. VAV systems
in general save a lot of the energy used for transportation and cooling of air. Never before has energy
use and indoor climate been this high on the agenda. The fact that energy use in the building sector
accounts for more than 40% of Europe’s CO2 consumption and that studies of modern office buildings
show that employees are only in their offices in 50-70% of their daily working hours gives every office
building an increased demand for a flexible indoor climate solution.
Lindab’s new VAV solution, Pascal, is developed and designed with the purpose of simplifying and
optimizing all phases of the building construction, from design to operation. This solution saves you for
unnecessary energy use, regulation equipment in the ducts and a complicated installation. Lindab
Pascal, the most simplified solution on the market with all you need for an optimized VAV system.
Lindab Pascal – Simplified VAV solution with full potential...
Lindab Pascal
Lindab Pascal is a solution that makes it simpler to fulfil the needs for a well functioning VAV system. Unlike
systems with constant pressure regulation, known in the market today, the duct layout is of less importance and
the need for regulation equipment is less in a Pascal solution. With Pascal it is possible to obtain correct airflows
in all parts of the system and in all operating conditions. In the heart of Pascal is the MBBV box that regulates
each diffuser in the system to correct airflow. The unique linear cone damper technology of MBBV makes it
possible to handle up to 200 Pa with low sound level and combined with an integrated actuator with accurate
flow measurement, it eliminates the need for any other regulation equipment between the fan and the MBBV
box. All components used in Pascal are with standard settings from factory and can easily be configurated after
installation. With only a few numbers of standard components, no special requirements for duct layout and a
flexible system set up, Pascal makes designing, installation and commissioning so much easier.
- Simplified VAV solution with full potential...
With Pascal it is possible to lower the energy consumption even more than traditional VAV systems. Instead of a
traditional pressure regulation of the fan, Pascal has a fan optimizer function that controls the fan speed of both
supply and exhaust fan. The system reads all damper positions on room level to ensure that enough air is available
in all parts of the system and ensures that the fan does not provide more pressure than necessary. Pascal also has
a demand control function that via a presence sensor can detect if there is no presence in a room and go to a low
standby airflow level to lower the energy consumption even more.
Communication
Exoline BUS system for optimized
communication between Regula
units and to overall BMS system.
Exhaust control
Secures exhaust balance according to
airflow in supply units in a simple way.
Fan optimizer
Reads all damper positions on room level
to lower the energy consumption by using
only necessary fan pressure.
Simple design...
Variable pressure system
Lindab Pascal is a variable pressure system, meaning that the pressure will vary in
all parts of the system, but correct airflows will be obtained in all operating conditions.
There is no need for pressure regulation of the duct system and therefore no special
demands for duct design. It also means fewer components in the duct system, since there is
no need for any other equipment between the fan and the diffusers in the room.
Flexible system layout
Lindab Pascal simplifies all phases of a VAV system, but simultaneously ensures high flexibility. Unlike traditional VAV
systems, no zoning is needed and duct design is of less importance with Pascal.
With Pascal the system is also prepared for future changes and requirements. With a flexible set-up additional diffusers can
easily be added, without any need for re-balancing the system. Also a new room set-up in the building can easily be adjusted
in Pascal with a simple change in the configuration.
Easy construction...
Standard installation
Lindab Pascal is based on a few numbers of standard components. All standard components can be installed and
after installation the individual configuration will be done. Less dampers and silencers in the system also makes the
installation of Pascal simple and fast.
Easy commissioning
With Lindab Pascal no traditional balancing is needed, only
system configuration. Configuration is easily done after
installation and can be performed by personal with no special
IT expertise. All settings and configuration can be done directly
in the displays of the Regula controllers, which has predefined
Pascal programs with standard default values.
Volume flow regulation
Desired airflow is obtained accurately
in all operating conditions with no
need for constant pressure regulation.
Demand Control
Lower the airflow to standby level
in case of no presence in rooms
to save even more energy.
Low energy consumption...
Low fan pressure
Lindab Pascal takes over the control of the fans to secure low energy consumption used for air
transportation in the system. Pascal reads all damper positions in the system and ensures that fans are
only using necessary pressure. With a Pascal fan optimizer function the fans are being controlled by input
from all rooms and no pressure regulation of the fans is needed. With no need for keeping a constant
pressure in the system, combined with low pressure drop in the regulating units, Pascal requires less
basic pressure from the fans than traditional VAV systems.
Demand control
Studies of modern office buildings show that employees are only in their
room in 50-70% of their daily working hours and therefore Pascal has a
demand control function that via a presence sensor can detect if there is
no presence in a room and go to a low standby airflow level to save even
more energy. CO2 control is also possible in Pascal.
