Kitchen ventilation is the branch of ventilation that specialises in the treatment of air from kitchens.〔http://www.hse.gov.uk/pubns/cais10.pdf〕 Kitchen ventilation presents the problems of grease, smoke and odours not usually found in other ventilation systems. Equipment used in kitchen ventilation uses an extractor hood or canopy and an filtering system. The fan for the ventilation system may be located within the kitchen or in the duct system nearby. == Requirements == An adequate kitchen ventilation system should achieve the following objectives: * remove cooking fumes at the source, i.e. as close to the cooking equipment as possible * remove excess hot air and introduce incoming cool clean air so that a comfortable environment is achieved. Inadequate ventilation can cause stress, contributing to unsafe systems of work and high staff turnover. * ensure that the air movement in the kitchen does not cause discomfort * provide sufficient air for complete combustion at fired appliances, and prevent the risk of carbon monoxide accumulating * be easy to clean, avoiding the build-up of fat residues and blocked air inlets which lead to loss of efficiency and increase risk of fire * be quiet and vibration free 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kitchen ventilation」の詳細全文を読む スポンサード リンク
