Description

This paper summarizes the primary results from ASHRAE Research Project RP-1202, a laboratory investigation into the effects that appliance diversity and position have on exhaust hood performance. The objective was to quantify the impact that appliance position and diversity, side panels, and front overhang had on the minimum exhaust rate required to provide capture and containment. The appliances included a gas broiler in the heavy-duty category, a two-vat gas fryer in the medium-duty category, and an electric full-size convection oven in the light-duty category. The appliances were operated in various combinations, with one, two, or all three appliances at cooking conditions under a 10-foot-long, wall-mounted canopy hood, and were evaluated in accordance with ASTM F 1704-99, Standard Test Method for Performance of Commercial Kitchen Ventilation Systems (ASTM 1999a). A supplementary study was conducted in parallel with this project and is discussed in a companion paper, “Effects of Range Top Diversity, Range Accessories, and Hood Dimensions on Commercial Kitchen Hood Performance” (Sobiski et al. 2006; Swierczyna et al. 2005b). By making what might appear to be subtle changes in appliance position and/or hood configuration, a wide range in the exhaust rates required for complete capture and containment was demonstrated.
