When selecting oil fume purification and smoke exhaust facilities in the kitchen of a hotel, priority should be given to the size of the smoke exhaust equipment. After determining the size of the smoke exhaust equipment, the size of the oil fume purifier equipment should be selected. Generally, the air volume of the oil fume purifier should be greater than 20% of the fan air volume.

具體到排煙風機的選型，需要根據煙罩的大小，爐灶數量，總管道長度，彎頭數量；排煙管路中其他設備阻力等參數選擇。

The specific selection of smoke exhaust fans needs to be based on the size of the hood, the number of stoves, the total length of the pipeline, and the number of elbows; Select parameters such as resistance of other equipment in the smoke exhaust pipeline.

酒店商用廚房抽排油煙通風系統設計原則和劃分要與客戶的投資方向、投資預算、能源效率、能源消耗、運行費用、生產流程等結合起來，

The design principles and division of the fume exhaust and ventilation system for hotel commercial kitchens should be combined with the client's investment direction, investment budget, energy efficiency, energy consumption, operating costs, production processes, etc,

排風量的確定和風速設計原則由兩部分組成:局部排風量和全面排風量。局部排風量應根據選用的灶具等設備種類、數量以及抽排煙的型式等加以確定，即根據爐灶等設備的平面布置圖,煙草種類,抽油煙離心風機的除油煙方式及設備產生風機性能的強度等因素進行確定。

The determination of exhaust air volume and the principle of wind speed design consist of two parts: local exhaust air volume and comprehensive exhaust air volume. The local exhaust air volume should be determined based on the type and quantity of selected stoves and other equipment, as well as the type of smoke extraction and exhaust, that is, based on the layout plan of the stove and other equipment, the type of tobacco, the method of removing oil smoke from the centrifugal fan for oil smoke extraction, and the strength of the fan performance generated by the equipment.

酒店廚房通風排煙系統在安裝時，也需要注意：要減少彎頭，盡量做到更短路線排放，要裝防火閥避免火災隱患；管道過長時要做好支架的固定，避免出現脫落；風機和凈化器盡量保持在一個水平位置上；連接件必須密封。

When installing the ventilation and smoke exhaust system in the hotel kitchen, it is also necessary to pay attention to reducing bends, minimizing emissions along the shortest possible route, and installing fire dampers to avoid potential fire hazards; When the pipeline is too long, the support should be fixed properly to avoid falling off; Try to keep the fan and purifier in a horizontal position as much as possible; The connecting parts must be sealed.

另外，廚房排煙風機凈化器安裝在室內的時候，一定要預留好后期檢修的空間。后期要定期做好管道的清理，避免發生安全隱患。

In addition, when installing the kitchen exhaust fan purifier indoors, it is necessary to reserve space for later maintenance. Regular cleaning of pipelines should be carried out in the later stage to avoid potential safety hazards.
