2. Productdevelopment TVE / RG22

3. Classic VAV in comparison to the new measuring principle
Series: TVR / Leo (Auranor)
Series: TVE
-measuring grid
Control damper
Tubes
Measurement above damper blade => variable C-value/ Characteristic map
High control accuracy even in case of unfavourable upstream conditions
Easy handling / Spare parts fit only in one direction
Any installation orientation also with static measurement
Measurement via grid=> Constant C-value
Upstream length min. 5 x D
Length of the controllers mm 3

4. TVE development
TVE Damper blade
Damper used for air regulation and volume flow measuring
No additional parts in the duct
Very short
Variant NW Variant NW 315 – 400
Variant NW 500 – 630 (Leo)
later also for rectangular units

5. TVE Tools:
· TVE damper 100 TVE damper 125 TVE damper 160 TVE damper 200 TVE damper 250 Casing Axle Sensor-Clip Angle indication plug Poti-cap · Transparent can be made if necessary: ,- €

6. Cross-sectional view through a TVE
TVE development
Cross-sectional view through a TVE
Details are registered as European patent
Transducer (static or dynamic)
Shaft with integrated dynamic pressure tubes
Damper with chambers
for + / - pressure

7. Transducer types for static an dynamic measurement
Dynamic Transducer
For clean air
Cheaper
Static Transducer
For poluted air e.g. dust (hospital application)
Axle is used to transmit the
dynamic pressure / petty patent registered!

8. Three Controller variants:
TVE / Easy
Modbus also with static transducer
TVE / XB0 (Compact)
TVE / XM0 (Modbus)
TVE / XS0 (static)

9. TVE development
Modbus RJ12 variant with plug connection Optimized for use with X-AIRCONTROL Modbus

10. Damper-leakage NW 100

11. Casing leakage (not even to measure really)

12. How to install? …. Do it as you want ;o) (only with dynamic transducers)

13. Measurements 180° turned TVE

14. Most important advantages according to this meeting
USP-list of the last TVE workshop with members from Austria, Switzerland and Germany
Most important advantages according to this meeting
Unfavourable upstream conditions allowed => less contruction place needed
Controls lower air velocities => Energy saving
Easy assembling => faster delivery
Plugs / no wire => no additional clamping box
No fixed streaming direction (dynamic tr.) => no faults possible
Other advantages against given solutions
Sizes 100 – 630 available (to the ISH )
Even with static transducers free mounting orientation
Only TROX will have this measurement principle and it is:
=> Easy to adapt on different controller types (start: TVZ)

15. Thank you!
