Laboratory Ventilation


Laboratory Ventilation Key Issues

• Safety ! Fume hood containment• Room pressurization• Speed of response to changes in airflow

demand or static pressure• Air Change Rates• Temperature Control• Energy Conservation


Accel® II Venturi Valve

• Integrates over 30 years of development and experience and with over 200 improvements

• Specially-designed conical diffuser• Inlet/Outlet insensitivity• Reduced low frequency noise• Wide turndown range (up to 20:1) • Precise repeatable positioning• No routine maintenance• Made in the USA• Pneumatic and electric actuators available

• High speed for critical applications• “Normal” speed for health care and flow tracking applications


The Phoenix Controls Legacy “We Don’t Measure Flow”

• Flow Metering vs. Flow Measuring• Flow measuring has a limited range of

operation.• Flow measuring requires long, straight duct runs

(not available in most applications).• Flow measuring is prone to inaccuracies due to

the caustic nature of laboratory exhaust air• Flow measuring has inherent time lags due to

airflow dynamics• Flow measuring requires periodic maintenance


Factory Calibration

• Drastically Reduces Commissioning Time• Can be pre-commissioned before supply and

exhaust air is connected• No sensors to set up or flows to adjust • No routine maintenance requirements


Factory Calibration


What Sets Us Apart

• Speed of Response SPEED NO• No Straight Ductwork Requirements• Pressure Independence• Ability to Accurately Control at Low Flows• No Regular Maintenance Requirements

Energy Saving Products and Applications

What does One (1) CFM of “Single Pass” Air cost to heat and cool at The

Ohio State University?


What Can Be Done?

• 6 energy saving trends in Laboratory Airflow Controls• Usage Based Controls®

• Fume hood decommissioning• Energy waste alert• Unoccupied settings• IAQ control ventilation


Proven Energy Saving Concepts


Usage Based Controls®


Lab Usage Patterns

• 24‐hour operation• 100% outside air (no recirculation) • Hood occupancy in short segments • Total hood usage typically one hour per day

and independent• Sash management varies widely

Usage Based Controls


Zone Presence Sensor®

• Available since the mid‐1990’s• One ZPS® per 8' hood

• Can be used in series for wider hoods• Field programmable via a USB port

• Detection zone• Setback times and

values• Lighting adjustments• Motion sensitivity


Sample Building Energy Costs

UBC


Fume Hood Decommissioning


Concept

• Ability to reduce or turn off fume hood exhaust when not in use

• Potential for huge energy savings • Teaching labs or hoods rarely used • Buildings not occupied• Understaffed research facilities

• Valve options• Valve minimum (i.e., 90 CFM)• Shut‐off Valves (i.e., 0‐5 CFM)



Function and Operation

• Can be initiated by: • Fume Hood Monitor

• Button sequence• External key switch• BMS command

• Ensures safety• Sash must be fully closed to initiate mode• Mode is automatically exited if sash is opened



Energy Waste Alert


Concept and Operation

• Notification when sash is left open and lab lights are off

• Features• Light sensor incorporated in monitor• Provides audible alarm• Displays "EnrG" on monitor

• Reminder to close the sashes at night

Energy Waste Alert


Unoccupied Settings


Unoccupied Settings

• Celeris®, Theris™ and Traccel® digital platforms• Lower ACH• Relaxed temperature control• Triggered locally or via BMS schedule

• Retrofit existing analog systems• Lower ACH


IAQ Control


Two Ventilation Concepts

• Air change rates• Reduce minimum ACH when air is

"clean"• Drive to higher ACH when

contamination is detected

IAQ Control


Lab Application: Next Generation VAV Control• Lab Multi-parameter DCV: Dynamic control of min.

ACH• Now all three factors affecting lab airflow can be varied• Significantly cuts energy & first cost, while enhancing safety

• Air Cleanliness• Total Volatile Organic Compounds

• Includes ammonia

• Particles – laser based particle counter

• Carbon Monoxide (CO)

• Comfort &Ventilation• Temperature

• Humidity or Dewpoint

• Carbon Dioxide (CO2)


Lab Monitoring Also Helps Ensure Lab Safety

• Validates the safe operation of a lab• Detect improper bench use of chemicals • Detect poorly containing fume hoods• Spills & rogue reactions rapidly sensed• Check lab pressurization, T & RH• Validates safe IEQ room conditions for animals

• Allows for safer lab airflow control• Increased hood capture from reduced drafts

• Drops room flows when dilution not needed• Greater dilution provided for spills, leaks, etc.

• 12 to 15 ACH’s can be provided automatically• Sources of leaks & emissions can be found

• With fact based data, source controls can be used

What it all means…

• Like most life-sciences labs, the airflows in Biodesign-B are primarily ventilation driven.

• Most labs in Biodesign-B are over-ventilated• Average ventilation flows can be safely reduced by >50%

when monitoring air cleanliness and responding to spills, etc.

• There are HUGE energy savings with FAST payback! • Several other soft benefits too!

• Safer hood operation• Quieter labs• Documented performance

A “Working” Laboratory

How Do you Define a “Working Lab?”


A “Working” Laboratory

• What checkpoints are in place to assure that labs are working?

• Are specifications being met?• What are the consequences?• What documentation of performance is required?• Who suffers if the specification is not met?


Laboratory Recommissioning

• Documents laboratory performance• Fume hood face velocities• Lab pressurization• Energy Usage

• Identifies Energy Savings Opportunities• Airflow reduction• Static pressure reduction• Other opportunities


Our Commitment

• Superior system performance• Local, factory certified technicians starting up each

project• Full commissioning of each system

• Airflow checked for each laboratory condition• We strive to make system “fail” instead of the easy route to

pass.• Contractor Support• Three year warranty on all equipment• Project budget is maintained
