From lessons learned in industrial air conditioning to noise and vibration
control of screw chillers, sessions in the technical program for the American
Society of Heating, Refrigerating and Air Conditioning Engineers’ (ASHRAE) 2001
Winter Meeting will focus on practical applications, real experiences and use
in the field.
The systems and applications and refrigeration tracks highlight the meeting,
which takes place Jan. 27-31, in Atlanta, Ga., at the Georgia World Congress
With continued focus on the need for alternative refrigerants, the HVAC&R industry
is challenged to satisfy the demand for applications using new refrigerants
while meeting higher operating efficiencies. An overview of the latest designs
for the basic components of industrial systems and applications are reviewed
in a seminar.
Noise problems associated with screw chillers, which are relatively new to
HVAC system design, such as noise sources, measurement standards and case studies
are examined in a seminar.
Refrigeration system design, applications and retrofits will be discussed in
a seminar, presenting some of the typical applications in the industrial refrigeration
Several sessions will look at various systems and applications. Lessons learned
in industrial air conditioning will be examined in a seminar addressing problems
arising in power plant ventilation and air conditioning. It covers personnel
safety issues, infiltration and exfiltration of unfiltered air, chemical corrosion
in heat exchangers, emission and temperature limits, measurements and associated
codes and standards.
Information on pumping design and performance modeling of geothermal heat
pump systems will be presented in a symposium.
The economic impact of the aging of pipe in HVAC systems will be studied in
a forum. It explores whether the impact of non-treated fluids and properly and
improperly treated fluids can be accurately projected.
Alternative technologies will be explored in several sessions. A seminar will
look at combining renewable power generation with energy-efficient and sustainable
building design in regard to applications in solar energy.
The use of life-cycle assessment tools for determining environmental performance
of buildings is examined in a seminar. Figures show that U.S. buildings in their
construction, use and demolition account for nearly 45% of domestic energy use
and more than 10% globally. The seminar advocates that design professionals
have a responsibility to minimize and mitigate the impact of buildings on the
A wide range of indoor air quality (IAQ) issues are covered, including make-up
air’s contribution to indoor air humidity problems. The majority of HVAC systems
are controlled by a thermostat alone, which is no longer acceptable. A seminar
looks at the challenges faced by system designers and equipment manufacturers
in controlling indoor humidity.
The challenges and issues of ventilation, cooling and dehumidification in
hot and humid climates will be addressed in a forum.
The use of chemically treated steam in humidification and whether steam is
compatible with good indoor air quality will be examined in a forum.
The issue of requiring carbon monoxide alarms in living spaces will be discussed
in a forum. The history of CO exposure and incidents will be provided, along
with information on field experience.
Programs on ASHRAE standards or guidelines include: A seminar on meeting the
requirements of Standard 90.1, Energy Standard for Buildings except Low-Rise
Residential Buildings, using energy recovery ventilation. A seminar introducing
the requirements of ASHRAE Guideline 12, Minimizing the Risk of Legionellosis
Associated with Building Water Systems.
A forum examining what requirements are needed in ASHRAE’s Standard 170P, Ventilation
of Healthcare Facilities.
A forum discussing the relevance of ASHRAE Standard 90.2, Energy-Efficient
Design of New Low-Rise Residential Buildings.
A forum addressing the revision of ASHRAE Standard 62-1999, Ventilation For
Acceptable Indoor Air Quality, through use of continuous maintenance.
The technical program is comprised of 49 seminars (application-oriented presentations
without papers), 16 symposia (presentations with papers on a central subject),
28 open-discussion forums, two technical sessions (paper presentations), a poster
session and a public session featuring Amory Lovins, co-author of Natural Capitalism:
Creating the Next Industrial Revolution. A total of 107 papers will be presented.
The exposition is co-sponsored by ASHRAE and the Air-Conditioning and Refrigeration
Institute. For more information, contact International Exposition Company by
