Abstract

This article uses color full-scale Schlieren for heat flow visualization of the kitchen exhaust hood. Using grease filters with same percentage of opening but different forms for measurements the heat flow escaping rate, noise, and air velocity of the kitchen exhaust hood under conditions of different percentage masking. The results show that using different grease filters without masking has no escaping heat flow. Employing the rectangular filter with side masking has the worst heat flow escaping. The top masking has also no heat flow escaping and the form with circular opening has the strongest absorbability. In this work, the smallest noise level is 65dB which appears at the situation of top masking. Moreover, kitchen exhaust hood without masking the air flow rate increase 3.17% of the air velocity than side masking.
