Kitchen vent hoods, Industrial kitchens of restaurants, hotels, hospitals, factories, etc. move large masses of air to control contaminants and therefore is very important design and calculation. Within the industrial bells are two types, simple hoods or hoods and self-powered. Hoods or simple, these hoods are suitable for use in regions with mild climate. They are considered simple because their air flow is taken from inside the kitchen, open sales or expelling it outside, ignoring the energy saving heating or cooling that may exist within the kitchen.
For kitchen vent hoods these campaigns suggest that the calculation is made based on the following procedure, the first Cubing the hood and extraction area, to do this, we get the initial air volume. Then, the air volume must be multiplied by the coefficient corresponding to Renewal industrial Air bells. See table of coefficients of air renewal. After then, calculate static pressure caused by products.
Procedure kitchen vent hoods to campaigns suggest kitchen vent hoods are Calculate static pressure drop caused by filters. Then, Calculate the required air intake and see if you have currently is suitable for air extraction system. Interesting observations, For proper extraction within the industrial, kitchen are All possible air currents should be eliminated, this will cause the speed of the suction hood has to be increased dramatically.
