KITCHEN VENTILATION METHOD AND SYSTEM FOR MAXIMIZING THE EXHAUST EFFICIENCY OF POLLUTED GAS CONTAINING THE RESIDUAL HEAT BY SMOOTHING THE EXHAUST OF GAS THROUGH AN EXHAUST DUCT
KITCHEN VENTILATION METHOD AND SYSTEM FOR MAXIMIZING THE EXHAUST EFFICIENCY OF POLLUTED GAS CONTAINING THE RESIDUAL HEAT BY SMOOTHING THE EXHAUST OF GAS THROUGH AN EXHAUST DUCT
PURPOSE: A kitchen ventilation method and a system are provided to reduce temperature difference between the room air and the external and accordingly to prevent the dew formation by pre-heating the external air supplied to the kitchen by using the residual heat of the polluted gas. CONSTITUTION: In a kitchen ventilation method, the polluted gas containing the residual heat of a kitchen is exhausted naturally to the outside through an exhaust duct(11) on the ceiling of the kitchen by the exhaust pressure of the gas ejected through a discharge duct(2) by operating a kitchen hood(1). The external air fed into the kitchen through a supply duct(21) from the outside exchanges heat with the polluted gas containing the residual heat of the kitchen by operating a supply fan(22) and then the heat exchanged external air is pre-heated and supplied to the kitchen.
