RESEARCH REPORT
This research will improve the consistency between the manufacturer and audit test facilities, which will result in less risk
and improved verifi cation 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 verifi cation of compliance with energy
effi ciency standards. Status: Active Project - Still need draft fi nal report, TC vote on report, and Technical Paper deliverable.

The Environmental Health and Safety professionals, laboratory designers and other ASHRAE Members need reliable
gaseous contaminant transfer data measurements methodologies to complete the necessary risk assessment when evaluating
energy recovery systems for their laboratory ventilation projects. Technologies shown to limit contaminant transfer would
allow greater energy savings and reduce the carbon footprint. Compared to commercial buildings, the opportunity for energy
savings in laboratories is much greater. ASHRAE should play a leadership role in optimizing the HVAC systems in laboratories
while keeping safety a top priority.
Test Results for Small Energy Exchangers to Large
Exchangers
May 2020 - June 2022 (P); Intertek; Principal Investigator: Krishnan Gowri
The proposed research will increase the utility of ASHRAE Standard 84 by validating its applicability to large exchangers
over a broad range of conditions. Air-to-air energy recovery is an important tool for reducing energy consumption in buildings
and is now required in ASHRAE standard 90.1-2013 in defi ned circumstances. The proposed research will support further
use of air-to-air energy recovery in Standard 90.1, helping to meet the ongoing goals for reduced energy consumption in
new and renovated buildings.

Cremaschi; TC 1.3, Liquid to Refrigerant Heat Exchangers; Co-sponsored by: MTG.LowGWP, TC 8.5,
Liquid-to-Refrigerant Heat Exchangers
This study would help the industry to understand the physics of thin fi lm evaporation phenomenon for pure low GWP
refrigerants and refrigerant/miscible oil mixtures on structured 3-D enhanced tubes and help optimize such exchangers for
air-conditioning and refrigeration applications. The basic objective of this project will be to perform spray evaporation heat
transfer and pressure drop tests on a tube bundle with low GWP refrigerants and refrigerant/miscible oil mixtures at various
temperature and pressure conditions of interest to air-conditioning and refrigeration industry. The universal correlations
and/or charts would be developed for the general benefi t of the stakeholders. The investigator s) is/are expected to present
the results of the study in a manner that clearly and quantitatively shows the enhancement factors achieved compared to
conventional fl ooded evaporators and its impact on the overall COP of a chiller.

especially related to the changes to the method since 1088-RP, to produce repeatability and reproducibility statements, and
to look for possible improvement to the method if needed. Multiple labs will be engaged to run interlaboratory comparison
testing for at least 5 types of HVAC particle fi lters. QA data will be collected in addition to the standard test data. This
project will require good study design, test planning including making sure the tests are run correctly, data analysis by
experienced eyes and standard ASTM procedures, and communicating the results through reporting, presentations, and
change suggestions for the method.
1785-RP Experimental Validation of Refrigerant Charge
Models in Coils for Residential Split Systems
August 2017 - January 2023 (P); Oklahoma State University; Principal Investigator: Christian
Bach; TC 8.11, Unitary and Room Air Conditioners and Heat Pumps, Co-sponsored by: TC 8.4,
Air-to-Refrigerate Heat Transfer Equipment and TC 6.3, Central Forced Air Heating and Cooling
Systems
This project will improve equipment models so that they may more accurately refl ect the real performance of actual
systems in the fi eld. This is of value to BEM practitioners as well as to equipment designers. The ASHRAE Handbook of
Fundamentals 2013) outlines several energy modeling tools that are widely used in the industry e.g., DOE2, EnergyPlus,
TRNSYS) and the current methodologies for equipment modeling Regression Models and First-Principal Models). Unitary
split systems, especially heat pumps, which are used widely in both Residential and Commercial applications pose unique
challenges. Since not every rated split system match is lab tested, modeling is leaned on heavily. A weak link in this process
is refrigerant charge inventory. Improving the robustness of charge migration modeling will result in greater confi dence in
the design and selection process for engineers in the fi eld, rating agencies, and manufacturers.
1789-RP Optical and Thermal Performance of Hollow Glass
Block Units
Sep. 2022 - Oct. 2024 (P); University of North Texas; Principal Investigator: Weihuan Zhao; TC
4.5, Fenestration
This research will provide useful results to update the section on HGB of the Fenestration chapter of future editions
of the ASHRAE HOF by including performance data of current HGB products. The aim of the project is to develop simplifi ed
models for implementation in existing fenestration design tools and building energy simulation software to enable glass block
industries, building design professionals and engineers generate design performance data and comply with the requirements
of relevant building energy effi ciency standards and building energy codes.
