plications. If only one surface roughness calculation is needed, the method
will be much simpler to apply. The method currently used for calculating
σy and σz will also need to be improved.
1824-RP Accounting for the Barometric Pressure Impacts
on Psychrometric Performance Testing of Unitary
Air-Conditioning and Heat Pump Equipment
April 2020 - September 2021; University of Louisiana at Lafayette; Principal Investigator: Peng
" Solomon " Yin; TC 8.11 (Unitary and Room Air Conditioners and Heat Pumps)
The goal of this project is to develop a set of guidelines for testing unitary air
conditioners and air-source heat pumps at different barometric pressures and a
correction procedure to adjust the measured results to standard conditions. Three
aspects need to be considered: the effect of barometric pressure on outdoor air
mass flow rate, the standard condition " corrected " indoor coil airflow rate impact
on fan power, and appropriate psychrometric conditions independent of barometric
pressure. The major beneficiaries of this research include ASHRAE, DOE, AHRI,
CEC, EPA, equipment OEMs, and rating laboratories. 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 to ensure
results are comparable to test facilities at other altitudes.
1830-RP Experimental Characterization of Aircraft Bleed Air
Particulate Contamination
April 2020 - September 2021; Kansas State University; Principal Investigator: Byron Jones; TC
9.3 (Transportation Air Conditioning)
ASHRAE Standard 161 was designated as a policy level standard by ASHRAE and
its development demonstrates ASHRAE's international leadership in aircraft cabin
air quality, an area of increasing national and international interest. The requirement
for bleed air contaminant monitoring is an important provision of the standard and
played a major role in bringing divergent interests to a consensus that allowed the
standard to be broadly supported. The requested research will provide the missing
information that allows us to know if ultra-fine particle sensing is a viable option
for meeting this requirement in the standard.
1831-RP Validation of a Test Method for Applying a
Standardized Frost Load on a Test Evaporator in
a Test Chamber with and Operating Conditioning
System
September 1, 2022-February 28, 2024; Creative Thermal Solutions; Principal Investigator:
Stefan Elbel; TC 10.7 (Commercial Food and Beverage Refrigeration Equipment)
Examine at least three approaches that can be used for indicating the
magnitude of a frost load accumulated on a unit cooler and that can be
also used as part of a walk-in refrigeration system testing in current test
chambers designed for performance measurement in accordance with
AHRI 1250-2014. The potential approaches will be the primary methods
for indicating that a full frost load has accumulated on the unit. The test
plan for the research involves the usage of a secondary box to allow direct

1833-RP Literature Review for Evidence of the Basis for
September 2019 - April 2021 (P); Affiliated Engineers; Principal Investigator: Roger Lautz;
MTG.ACR (Air Change Rates)
This project will foster and engage ASHRAE relationships with other organization
memberships and in turn strengthen member value proposition. This project creates
a learning endeavor that could be emulated to additional standards or activities
within ASHRAE and outside of ASHRAE and to help promote ASHRAE as a leader
in ventilation guidance.
1836-RP Developing a Standardized Categorization System
for Energy Efficiency Measures
September 2019 - November 2020 (P); Univ. Cincinnati; Principal Investigator: Amanda Webb;
TC 7.6
The objective of this project is to develop a standardized system for the
categorization and characterization of energy efficiency measures (EEMs).
The scope of the project will include a literature review of existing EEM
lists and categorization systems; development and demonstration of a new,
standardized categorization system; development and demonstration of a
common set of properties for characterizing each EEM. The project tasks
will be summarized in interim reports and a final report at the completion
of the project.
1837-TRP The Effects of Ventilation in Sleeping Environments;
October 2019 - November 2022 (P); Technical University of Denmark; Principal Investigator:
Pawel Wargocki; Co-PI Li Lan; TC 2.1 Physiology and Human Environment
The overall objective of the proposed work is to document the effects
of poor ventilation in sleeping environments and the consequences for
healthy living and working. Specific objectives include: measurement of the
actual ventilation rate in bedrooms and comparison with the requirements
prescribed by the standards; examination of the effects of ventilation
on the air quality in sleeping environments, and how this affects sleep,
next-day well-being and next-day ability to work; determination of the
minimum outdoor air supply rate to eliminate negative effects of poor
bedroom IAQ on sleep quality; and revision of ventilation requirements in
sleeping environments.

measurement of the injected moisture for the verification of the viability
of the primary methods. The objective is to determine which primary
method provides the most repeatable indication that a full frost load has
accumulated, without requiring a direct measurement of the frost mass,
or of the frost volume with the dedicated secondary box.
