Smoke exhaust and air supply in hotel kitchens are generally achieved through specialized ventilation systems. In the design, it is necessary to consider the oil smoke and heat generated in the kitchen, and handle it through appropriate equipment and pipelines.

1. 排煙系統(tǒng)：主要功能是將廚房內(nèi)產(chǎn)生的油煙和有害氣體排出室外，確保良好的室內(nèi)空氣質(zhì)量。排煙系統(tǒng)的計(jì)算一般涉及以下幾個(gè)方面：

1. Smoke exhaust system: The main function is to exhaust the oil smoke and harmful gases generated in the kitchen from the outside, ensuring good indoor air quality. The calculation of smoke exhaust systems generally involves the following aspects:

- 油煙產(chǎn)生量：根據(jù)廚房設(shè)備數(shù)量、種類，以及每小時(shí)的烹飪操作時(shí)間等參數(shù)來估算油煙的產(chǎn)生量。

-Oil fume generation: estimate the amount of oil fume generated based on parameters such as the number and type of kitchen equipment, as well as the cooking time per hour.

- 風(fēng)量計(jì)算：根據(jù)廚房的面積、廚房內(nèi)設(shè)備的工作狀態(tài)，以及油煙的產(chǎn)生量等來確定需要排出的風(fēng)量。

-Air volume calculation: Determine the air volume to be discharged based on the area of the kitchen, the working status of the equipment in the kitchen, and the amount of oil smoke generated.

- 風(fēng)機(jī)選擇：根據(jù)計(jì)算得出的風(fēng)量需求，選擇合適的風(fēng)機(jī)類型和數(shù)量，以確保排煙效果良好。

-Fan selection: Based on the calculated air volume demand, select the appropriate fan type and quantity to ensure good smoke exhaust effect.

- 排煙管道設(shè)計(jì)：根據(jù)實(shí)際情況確定排煙管道的長度、直徑等參數(shù)，以保證排煙系統(tǒng)正常運(yùn)行。

-Smoke exhaust duct design: Determine the length, diameter, and other parameters of the smoke exhaust duct based on the actual situation to ensure the normal operation of the smoke exhaust system.

2. 送風(fēng)系統(tǒng)：主要是為廚房提供新鮮空氣，保持廚房內(nèi)的良好通風(fēng)環(huán)境，確保員工工作舒適。送風(fēng)系統(tǒng)的計(jì)算一般包括以下幾個(gè)方面：

2. Air supply system: mainly used to provide fresh air for the kitchen, maintain a good ventilation environment inside the kitchen, and ensure comfortable work for employees. The calculation of the air supply system generally includes the following aspects:

- 送風(fēng)量計(jì)算：根據(jù)廚房的面積、人員數(shù)量和需求以及通風(fēng)效果要求，確定需要提供的送風(fēng)量。

-Calculation of air supply volume: Determine the required air supply volume based on the area of the kitchen, the number and demand of personnel, and the ventilation effect requirements.

- 風(fēng)口設(shè)置：根據(jù)廚房布局和設(shè)計(jì)要求，在合適數(shù)量和位置上設(shè)置送風(fēng)口，以達(dá)到均勻送風(fēng)。

-Air outlet setting: According to the layout and design requirements of the kitchen, set up air supply outlets in appropriate quantities and positions to achieve uniform air supply.

- 送風(fēng)管道設(shè)計(jì)：根據(jù)送風(fēng)口位置和距離，確定送風(fēng)管道的長度、直徑等參數(shù)，以確保送風(fēng)系統(tǒng)的正常運(yùn)行。

-Air supply pipeline design: Determine the length, diameter, and other parameters of the air supply pipeline based on the location and distance of the air supply outlet to ensure the normal operation of the air supply system.

總之，排煙和送風(fēng)系統(tǒng)的計(jì)算需要綜合考慮廚房的大小、布局、設(shè)備種類和工作時(shí)間等因素，并參考相關(guān)的規(guī)范和標(biāo)準(zhǔn)來進(jìn)行設(shè)計(jì)。這樣可以保證酒店廚房的排煙和送風(fēng)效果達(dá)到要求，為員工提供一個(gè)安全、健康的工作環(huán)境。

In summary, the calculation of smoke exhaust and air supply systems needs to comprehensively consider factors such as the size, layout, equipment type, and working time of the kitchen, and refer to relevant norms and standards for design. This can ensure that the smoke exhaust and air supply effects of the hotel kitchen meet the requirements, providing employees with a safe and healthy working environment.
