ASHRAE through its Technical Committee
TC-5.10 Kitchen Ventilation, represents the most visible
and active group in researching, testing and code development
for CKV in the United States. UP
YOUR STACK™ will work
to bring you an understanding of projects, plans and committee
meetings.

Rich Swierczyna of the Architectural Energy Lab in Wood Dale, Illinois presented an extensive report on the testing work going on in conjunction with ASHRAE Research Project No. 1202-RP. That project is described at the bottom of this page. Details will be discussed when ASHRAE approves and releases the information.

1202-RP - Effect on Commercial Kitchen Hood Performance of Appliance Diversity and Position
Architectural Energy Corporation
Principal Investigators: Richard Swierczyna, Donald Fisher
TECHNICAL COMMITTEE - TC 5.10, Kitchen Ventilation |
| Usually multiple appliances operate under an exhaust hood in kitchens. This practice is driven by the economy of reducing the total number of exhaust hoods, ducts, penetrations and exhaust hoods. It is also common practice to cluster commercial kitchen cooking appliances together. Current U.S. codes specify that if a kitchen has several appliances operating under an unlisted hood, the exhaust flow must be set at the highest required flow rate for the "worst case" appliances operating under the hood. For listed hoods, most manufacturers follow the same practice specifying exhaust flows. At the same time, it is fairly well known that hood performance is enhanced by placing appliances that require higher exhaust airlflows, such as char broilers under the middle rather than at the ends of hoods. Yet, there is no research to qualify and quantify this practice. |
| PROJECT DESCRIPTION: The objective will build on earlier efforts by extending the capture and containment (C&C) studies from single appliance operation to multiple appliances underneath hoods. The project will also examine how appliance positioning underneath hoods may impact C&C airflows. The results of this study will be incorporated into codes, standards and design guides to assist code officials, commercial kitchen and building designers, consulting engineers and ventilation manufacturers with efficient restaurant design and operation. |
2004-2005 ASHRAE RESEARCH REPORT
Michael Vaughn, P.E., ASHRAE's Manager of Research/Technical Services reports in the October 2004 ASHRAE Journal that there are currently 64 active priority projects. Overall, a total of 92 projects are in varying stages of development with an estimated cost of $6,457,000. Much of the work is accomplished by an extensive network of dedicated and unpaid volunteers. More information about the work and active research projects can be found on the "Research" page at www.ashrae.org. |
