请注意，商用烹饪设备排气系统对餐饮服务设施的总能耗有重大影响。美国每年的能源成本接近30亿美元。指出通过降低通风率可以显著节约能源和成本。记录了一项初步调查，该调查使用计算机模拟快速服务气体中壁挂式顶棚和后排风罩使用不同水平恒定通风率的效果- 电动和全电动餐厅。单位:双关键词:1997年，厨房，餐厅，节能，通风，研究，计算机程序，排气罩，商业，成本:研讨会，ASHRAE交易，第103卷，第2部分，波士顿1997

Notes that commercial cooking equipment exhaust systems have a significant impact on the total energy consumption of food service facilities. Puts the annual energy cost for this in the USA at approaching $3 billion. Points to the significant energy and cost savings achievable by reducing ventilation rates. Documents a preliminary investigation using computer simulations of the effects of using different levels of constant ventilation rates for wall-mounted canopy and backshelf exhaust hoods in quick service gas-electric and all-electric restaurants.Units: DualKEYWORDS: year 1997, Kitchens, restaurants, energy conservation, ventilation, research, computer programs, exhaust hoods, commercial, costs
