Why Variable Air Volume Controls For
Laboratories?
4
Reasons for TRIATEK Laboratory VAV Controls

• Safety
• Better Control
• Energy and Other Cost Savings
• Integration to Building Automation System

5
Safety

• Maintain Hood Capture Ratios
• Constant Face Velocities
• Reduced Eddy Currents

6
Why TRIATEK for Safety?
7
Our System is Designed for Safety

• Active Control of Hood Face Velocity
• Audible and Visual Alarms to Warn of Unsafe
  Conditions
• Meets or Exceeds Safety Requirements achieved by
  Proper Air Flow Control
• Fume Hood Exhaust Control Valve Will Fail in Open
  Position in the Event Power Failure

What Makes Up The TRIATEK Fume Hood Controller
System?

• HMS-1600 Controller
• Flow Sensor
• Monitor and Display
• Venturi Valve
• Fast Acting Actuator

10

11
TRIATEK Measures Hood Face Velocity.
12
Active Velocity Measurement

• Looking at the laws of physics, first we have a
  box.
• Next, three openings are added to the box.
• Then a fan is added to one of the openings in the
  box.
• With the fan on, the velocity through both
  remaining openings is identical.

We apply the same Principle to Fume Hood Velocity

Air Flow Through the Sensor Opening is the Same
as Through the Hood Sash Opening

14
The Sensor Itself Must be Viewed through a
Microscope!

• Micro Machined
• Accuracy 2 FPM _at_ 200 FPM
• Senses Direction of Flow
• Measures Very Low Flow
• Flow Sensor is Repeatable
• Designed to Minimize Dirt Infiltration

Why TRIATEK Flexibility for Your Lab Building?

• Seamless Integration with Most Building
  Automation Systems
• Easy to Set Up and Program
• Add Fume Hoods Without Adding HVAC Equipment
• Move Hoods from One Lab Area to Another Without
  Changing Supply Ducts, Building Stays in Balance
• Upgrade Features

Volumetric Control Formula - Hood Exhaust
General Exhaust Supply Air Room Offset

• TRIATEK's Laboratory Zone Controller used in
  conjunction with TRIATEK Fume Hood Controllers
  and Venturi Valves provides accurate
  pressurization of a laboratory space.
• The Laboratory Zone Controller
• Measures and sums Fume Hood Exhaust and general
  exhaust to calculate Total Exhaust Flow.
• Measures and controls Supply Air Flow using Room
  Volumetric Offset. The Supply Air Flow will track
  the Total Exhaust Flow.

23
Volumetric Control Formula -(continued)

• Maintains negative or positive room
  pressurization.
• Optional Temperature Override Control allows
  supply air to increase cooling in room while
  adjusting general exhaust to maintain proper room
  pressurization.
• Provides Emergency Exhaust Override control from
  contact closure. Control sequences are
  configurable to either
• Increase room air changes by overriding hood
  exhaust to maximum, general exhaust to minimum,
  supply air will track total exhaust or
• Purge the room by overriding hood exhaust to
  maximum, general exhaust to minimum, supply air
  set to minimum.

How TRIATEK Saves You Money?
25
Energy and Other Cost Savings

• Reduced Volume of Air Exhausted by the Fume Hoods
• Building HVAC Equipment Can Be Sized Smaller for
  Less Air Requirements (Diversity)
• Smaller Air Requirements Equals Smaller Duct
  Requirements (Diversity)
• Single Exhaust Fan System over Multiple Hood Fans

26
Constant Volume Fume Hood vs. VAV Fume Hood
27
What is Diversity?

• The Study of the Existing Users Facility to
  Determine the Active Hood Use
• Establish a Factor of the Hood Use
• Study Chemicals Used and Heat Load Requirements
  to Establish Air Changes Per Hour
• Bring These Two Quantities Together and Establish
  the Project Design Diversity

28
How is Diversity Used?

• The Design Diversity is Used to Downsize the
  Air System
• This includes the following
• Exhaust Fan
• Exhaust Duct
• Supply Air Handler
• Supply Air Duct
• Chiller / Reheat Capacity

29
How Much Can Diversity Save?

• Depending on the Building, the Discipline of the
  Users and the Diversity , a VAV System with a
  Strong Diversity, the Control System Pay Back is
  .8 Years.
• If no Diversity is used and the Exhaust and
  Supply System is Sized for Full Capacity, the VAV
  System Pay Back is Around 3 Years.

  High-Performance Lab HVAC Design.
