该州表示，现代购物中心的美食区通常使用主厨房排气系统，该系统由多个租户空间中的多个排气罩组成，所有排气罩都连接到一个主排气管和风扇。与多租户、单租户系统相比，该系统的优势在于灵活性强、首件成本低、通过上层的竖井空间小，且易于维护。与油腻排气相关的火灾危险意味着，主厨房排气系统的成功设计面临一些特殊挑战，尤其是确定主管道系统的尺寸，实现适当的空气平衡和防火。 讨论了master厨房排气系统的设计问题，并提出了一些解决方案。关键词:厨房、购物中心、排气管、排气通风、餐饮、商业、设计、灵活性、防火引用:ASHRAE Trans。1992年，第98卷，第1部分，论文编号AN-92-16-2，1199-1213，9个图，6个标签

States that master kitchen exhaust systems, consisting of multiple exhaust hoods in multiple tenant spaces all connected to a single main exhaust duct and fan are commonly used in food courts in modern shopping centres. Advantages over multiple, single-tenant systems are flexibility, low first cost, reduced shaft space through upper floors and ease of maintenance. Fire hazards associated with a greasy exhaust mean that there are several special challenges to successful design of master kitchen exhaust systems, especially sizing the main ductwork, achieving proper air balance and fire protection. Discusses the design problems presented by master kitchen exhaust systems and proposes some solutions.KEYWORDS: Kitchens, shopping centres, exhaust ducts, exhaust air ventilation, catering, commercial, designing, flexibility, fire protection
