RESEARCH REPORT
This research will improve the consistency between the manufacturer
and audit test facilities, which will result in less risk and improved verification
of compliance standards. This project will provide technical detail to
HVAC testing laboratories that test unitary systems where the air must
be sampled for both dry bulb temperature and humidity. This sampling
impacts all users of psychrometric test facilities from the development
of performance ratings to the verification of compliance with energy efficiency
standards.
1734-RP Reproducing a Representative Urban Atmospheric
Aerosol Distribution at High Concentration in
the Laboratory for Air Filter Ageing to be used
in ASHRAE GPC 35P for Determining the Energy
Consumption Caused by Air Filters
August 2017 - December 31, 2021 (P); Purdue University, Principal Investigator: Brandon
Boor; TC 2.4, Particulate Air Contaminants and Particulate Contaminant Removal Equipment,
Co-sponsored by: SSPC 52. Method of Testing General Ventilation Air Cleaning Devices for Removal
Efficiency by Particle Size
The results from this work statement would affect the energy usage and
design criteria for several ASHRAE Handbook Chapters and Standards. The
Handbook chapters that would be affected are Chapter 29-Air Cleaners for
Particulate Contaminants, HVAC Systems and Equipment Handbook; and
Chapter 46-Control of Gaseous Indoor Air Contaminants, Handbook-Applications.
1741-RP
Understanding Fan Coil Components and How
January 2017 - March 2020 (P); University Louisiana Lafayette; Principal Investigator, Peng
Yu; TC 5.3, Room Air Distribution, Co-sponsored by: TC 4.7, Energy Calculations & TC 7.7, Test &
Balance
The experimental results and recommendations will result in previously
unavailable part load capacity and efficiencies maps for fan coil systems.
The new tools and modeling options developed will improve the ability of design
engineers to evaluate and predict the energy and comfort performance
of buildings using fan coil systems. The better understanding of efficiencies
at part load operations achieved from this project will allow more confident
applications by system designers. This will reinforce the value of ASHRAE
guidelines to building systems, and support ASHRAE's net-zero energy
design strategies. This research will be of great value to the Engineering
community and provide more pertinent and accurate information in the
selection of fan coils for any given application. In obtaining the accurate
information needed for fan coil selection, sizing issues will decrease and
reduce overall energy consumption significantly.
1743-RP Effect of Inlet Duct and Damper Design on ASHRAE
37/116 Fan Performance and Static Pressure
Measurements
August 2017 - February 2020 (P); Oklahoma State University, Principal Investigator; Christian

They Relate to Energy Consumption and Energy
Modeling
The major benefit of this project is to provide technical clarification to
HVAC testing laboratories when testing samples. This subject impacts
all users of unitary air-conditioning equipment such as DOE, California
Energy Commission, independent test facilities and manufacturers of
unitary equipment. Standardization will provide more consistent setups
and repeatability between manufacturer's laboratories and 3rd party
certification laboratories.
1755-RP Impact of Gaseous Contamination and High
Humidity on the Reliable Operation of Information
Technology Equipment in Data Centers
July 2016 - Completed November 2019; Syracuse University; Principal Investigator, Jianshun
Zhang; TC 9.9, Mission Critical Facilities, Data Centers, Technology Spaces and Electronic
Equipment; Co-sponsored by: TC 2.3, Gaseous Air Contaminants and Gas Contaminants Removal
Equipment
The project will address the impact that gaseous contamination has when
adopting the expanded thermal guidelines for data processing equipment.
Specifically, it will look at the impact that the expanded acceptable humidity
envelope has on IT equipment reliability when subject to environments that
have higher than normal concentrations of gaseous contaminants.
1756-RP Evaluation of Particle Sensors for Indoor Air Quality
Monitoring and Smart Building Systems
September 2017 - March 2020 (P); Ohio State University; Principal Investigator, Andrew May;
TC 2.4, Plant and Animal Environment, Co-sponsor: TC 7.5, Smart Building Systems
The objectives of this proposed research are to fully test and document
the performance of a large number of commercially available PM sensors
and to provide recommendations for developing ASHRAE standards and
guidelines for evaluating their performance for applications in IAQ monitoring
and integration into smart building systems.
1759-RP Impact of Airflow on Thermal Performance of
Airspaces Behind Cladding (Phase 1 of 2)
September 2018 - August 2020 (P); Swiss Federal Institute of Technology; Principal Investigator:
Dolaana Khovalyg; TC 4.4, Building Materials and Building Envelope Performance
The objective of this project is to quantify the effect of and establish testing
and design recommendations to account for the impact of air exchange
rates or ventilation air flow) on the thermal resistance of vertical air spaces
behind selected cladding systems that are exterior to the air barrier. It is
envisioned that the air space behind the selected claddings will include
assemblies with and without at least one surface that is perpendicular
to the primary direction of heat flow with an initial total hemispherical
emittance less than 0.10. Air exchange rates or ventilation flows into and
out of the airspace and the impact on thermal resistance will be assessed
and used in testing and analysis of thermal performance. Results will be
used to recommend changes and additions to applicable test standard s),
the ASHRAE Handbook of Fundamentals [9], and ASHRAE Standard 90.1.
