Completed Research - December 2007

1189-RP, Investigation of Mechanism and Operating Environments that Impact the Filtration Efficiency of Charged Air Filtration Media

Electrically charged filter materials are more common than ever in air cleaning applications. However, studies have shown that standard air filter tests do not reveal all phenomena that can take place when charged air filters are exposed to various contaminants. This research project helps designers better understand the performance of these charged air filtration media. The project studies behavior of various charged filter materials, performs lab and field testing, and characterizes factors such as operating conditions, particle size, and resistivity on filter efficiency degradation and pressure drop.

1189-RP was sponsored by TC 2.4, Particulate Air Contaminants and Particulate Air Contaminant Removal Equipment. The principal investigator was Matti Lehtimaki of VTT Automation.

1194-RP, Dynamic Modeling Of Chilled Water Cooling Coils

This research developed a fully validated transient chilled water cooling coil model. It is believed to be the first fully validated by experimental data. These computationally efficient models are valuable tools for developers and can help speed development of system control and fault detection and diagnostic (FDD) algorithms.

Four technical papers were submitted for future publication in the ASHRAE HVAC&R Research and future ASHRAE meetings.

1194-RP was sponsored by TC 7.4, Building Operation Dynamics. The principal investigator was Dr. James Braun of Purdue University. Research Promotion By Darcy Carbone I would like to thank everyone who has already donated to the Research Promotion campaign for their generosity. I am continuing to beg all the others to please, please, please consider donating whatever you can. Please fill out the form on the back cover and mail it to me with whatever contribution you can make. Another way that people can donate using a credit card is via the internet at https://www.ashrae.org/aboutus/resource_promotion (if doing it this way, please be sure to put Boston down under “Assigned ASHRAE Chapter:”). As always your generosity is greatly appreciated and will be recognized in the newsletter throughout the year. I realize this is a bad time for many of us coming out of the Holiday season with credit card bills and such, but remember it is tax deductible and goes to a very good cause. This fund goes to research projects of great importance to us in fields such as energy conservation, food preservation, and improved operating room environments that result in fewer post-operative infections. We still have to raise about $14,000 this year. Every contribution is appreciated (large or small) as it takes participation by many members in order to support this important campaign (e.g. a $30 per year or $2.5 per month, contribution from ½ of our members would suffice to beat the goal that ASHRAE has set for our Chapter). Thanks again!
