ASHRAE - CELEBRATING 125 YEARS

for engineers on the application of clean spaces.† The
1966 and 1971 Handbooks combined "clean spaces"
with computer rooms, while 1974 saw the first solitary
chapter covering "clean spaces." A terminology section
was added in 1966. Clean space applications continued to warrant special attention as Task Group in TC
9.2 Industrial Air Conditioning until its elevation to a
Technical Committee TC 9.11 in 1996.
ASHRAE guidebooks and handbooks have followed
advances in cleanroom standards referencing FEDSTD-209 in the 1966 handbook and the ISO Standards
soon after their publication in the early 2000s. The
Handbook added a section on the use of computational
fluid dynamics (CFD) in 1995, providing updates on CFD
application and benefits ever since. Energy savings in
cleanrooms were also added in the 1990s.
Under the auspices of TC 9.11, Clean Spaces, and seeking
input from experts around the world, the ASHRAE Design
†ASHRAE Guide Books and Handbooks combined clean spaces and
computer rooms until 1974 when Clean Spaces became a standalone chapter in the ASHRAE Handbook-HVAC Applications.

Guide for Cleanrooms: Fundamentals, Systems, and Performance
was published in 2018. The design guide covers the latest
information on fundamentals of contamination control,
cleanroom air management, particle theory, application
of CFD and select industry applications.26

Conclusion
The application of cleanrooms has become a common
method of controlling contamination and improving
the environment for people, equipment and materials.
ASHRAE has been providing air-conditioning engineers
guidance on cleanrooms for over 50 years and will continue into the future.

In business, your reputation is all you have
Callbacks waste time and money. Your local reputation can
take years to build and be lost in an instant. For HVAC
contractors looking to deliver healthy homes to satisfied
customers, installing high-powered ventilation that assures
good indoor air quality is a must.
3 ESSENTIALS FOR HVAC CONTRACTOR SUCCESS
* Fast, professional installations the first time, every time
* Avoid costly callbacks & keep your profits safe
* Protect your reputation & grow your referral business

Panasonic fans are engineered to perform beyond
minimum benchmarks to provide powerful airflow
and overcome static pressure at the 0.375" level more
common on typical installations. The result? Greater airmoving power that removes mold-causing moisture and
polluted air from the home to make healthy living a reality.
