The smoke exhaust and ventilation design of catering kitchens is an important step to ensure air circulation in the kitchen and eliminate smoke, oil fumes, and odors. The following are the key considerations for smoke exhaust and ventilation design in general catering kitchens:

確定通風(fēng)需求：根據(jù)廚房的大小、烹飪設(shè)備的數(shù)量和類型，確定適當(dāng)?shù)耐L(fēng)量需求。通常，廚房的通風(fēng)量應(yīng)滿足當(dāng)?shù)亟ㄖ?guī)范和衛(wèi)生要求。

Determine ventilation requirements: Determine appropriate ventilation requirements based on the size of the kitchen, the number and type of cooking equipment. In general, the ventilation rate of the kitchen should meet the local Building code and sanitary requirements.

排煙系統(tǒng)設(shè)計：

Smoke exhaust system design:

a. 確定排煙通道的路徑和布局，通常應(yīng)將排煙通道直接連接到室外，遠(yuǎn)離通風(fēng)窗戶和進(jìn)風(fēng)口。

a. Determine the path and layout of the smoke exhaust passage, usually connecting it directly to the outside, away from ventilation windows and air intakes.

b. 使用合適的排煙罩或排煙罩組合，覆蓋烹飪設(shè)備上方，以收集并導(dǎo)出煙霧和油煙。

b. Use a suitable smoke exhaust hood or combination of smoke exhaust hoods to cover the cooking equipment to collect and export smoke and fumes.

c. 考慮使用煙霧凈化裝置或油煙凈化設(shè)備，以提高排煙效果和凈化空氣質(zhì)量。

c. Consider using smoke purification devices or oil fume purification equipment to improve smoke exhaust efficiency and purify air quality.

進(jìn)風(fēng)系統(tǒng)設(shè)計：

Air intake system design:

a. 確保廚房內(nèi)有足夠的進(jìn)風(fēng)口，以補(bǔ)充排煙時的空氣流入。進(jìn)風(fēng)口應(yīng)位于離排煙通道遠(yuǎn)的地方，以避免煙霧和異味逆流。

a. Ensure that there are sufficient air intakes in the kitchen to supplement the air flow during smoke exhaust. The air inlet should be located far away from the smoke exhaust duct to avoid backflow of smoke and odors.

b. 考慮使用過濾器和風(fēng)幕機(jī)等設(shè)備，以過濾進(jìn)入廚房的空氣并防止外部污染物進(jìn)入。

b. Consider using equipment such as filters and air curtains to filter the air entering the kitchen and prevent external pollutants from entering.

風(fēng)機(jī)選擇和布置：

Fan selection and layout:

a. 選擇適當(dāng)?shù)娘L(fēng)機(jī)類型和風(fēng)機(jī)容量，以滿足通風(fēng)需求并確保足夠的排風(fēng)效果。

a. Select the appropriate fan type and capacity to meet ventilation needs and ensure sufficient exhaust effectiveness.

b. 風(fēng)機(jī)的布置應(yīng)使其與排煙通道和排煙罩相連，以有效地抽出煙霧和油煙。

b. The layout of the fan should be connected to the smoke exhaust channel and hood to effectively extract smoke and oil fumes.

排煙管道和風(fēng)道設(shè)計：

Smoke exhaust duct and air duct design:

a. 確保排煙管道和風(fēng)道的直徑、材質(zhì)和布局滿足建筑規(guī)范和通風(fēng)要求。

a. Ensure that the diameter, material and layout of smoke exhaust pipes and air ducts meet the Building code and ventilation requirements.

b. 避免管道和風(fēng)道彎曲和阻塞，以確保順暢的空氣流動和排煙效果。

b. Avoid bending and blocking of pipelines and air ducts to ensure smooth air flow and smoke exhaust effect.

措施：

Safety measures:

a. 安裝火災(zāi)報警系統(tǒng)和排煙控制系統(tǒng)，以監(jiān)測和控制廚房內(nèi)的煙霧和火災(zāi)風(fēng)險。

a. Install a fire alarm system and smoke exhaust control system to monitor and control smoke and fire risks in the kitchen.
