一、选购排烟罩的实用建议

1、 Practical Suggestions for Choosing Smoke Exhaust Hood

1. 根据厨房规模选 “尺寸与功率”

1. Choose "size and power" based on the size of the kitchen

小型厨房（3 个以下灶台）：选择长度 1.5-2 米的排烟罩，风机功率 1000-2000 立方米 / 小时，确保每个灶台上方有 50 厘米的罩体覆盖。

Small kitchen (with 3 or fewer stoves): Choose a 1.5-2-meter-long exhaust hood with a fan power of 1000-2000 cubic meters per hour, ensuring that there is a 50cm hood covering above each stove.

中型厨房（4-8 个灶台）：罩体长度 3-5 米，风机功率 3000-5000 立方米 / 小时，吸风口分区域设置，每个灶台对应独立的吸风单元。

Medium sized kitchen (4-8 stoves): The length of the hood is 3-5 meters, the fan power is 3000-5000 cubic meters per hour, the suction port is set in different areas, and each stove corresponds to an independent suction unit.

大型厨房（8 个以上灶台）：定制化排烟罩，长度可达 10 米以上，采用双风机并联设计，总功率超过 10000 立方米 / 小时，确保油烟即时排出。

Large kitchen (8 or more stoves): Customized smoke exhaust hood, with a length of over 10 meters, adopting a dual fan parallel design, with a total power of over 10000 cubic meters per hour, ensuring immediate discharge of oil fumes.

2. 关注 “密封与导流设计”

2. Pay attention to "sealing and flow design"

罩体边缘与墙面或吊柜的连接处需加装密封条，避免油烟从缝隙逃逸，尤其是角落位置，密封条能形成完整的 “油烟包围圈”。

Sealing strips should be installed at the connection between the edge of the hood and the wall or hanging cabinet to prevent oil fumes from escaping through gaps, especially in corners. The sealing strips can form a complete "oil fume enclosure".

导流板的倾斜角度应在 30°-45° 之间，角度过小不利于油烟汇聚，过大则可能遮挡厨师视线，优质排烟罩的导流板会经过风洞测试，确保油烟流动阻力最小。

The inclination angle of the deflector should be between 30 ° -45 °. If the angle is too small, it is not conducive to the convergence of oil fumes, and if it is too large, it may obstruct the chef's line of sight. The deflector of high-quality exhaust hoods will undergo wind tunnel testing to ensure the minimum flow resistance of oil fumes.

3. 材质与清洁便利性平衡

3. Balance between material and cleaning convenience

日常油烟量大的厨房，优先选择 2 毫米厚的 304 不锈钢罩体，虽然成本较高，但耐用性强，5 年内无需更换。

For kitchens with high daily oil fume volume, it is recommended to choose a 2mm thick 304 stainless steel hood. Although the cost is high, it has strong durability and does not need to be replaced within 5 years.

注重美观的酒店厨房，可选择表面拉丝处理的不锈钢或铝合金材质，搭配隐藏式滤网，既保持整洁外观，又便于拆卸清洁（滤网建议每周清洗一次，避免油垢硬化）。

A hotel kitchen that values aesthetics can choose stainless steel or aluminum alloy materials with brushed surface treatment, paired with hidden filters, which not only maintain a clean appearance but are also easy to disassemble and clean (it is recommended to clean the filter once a week to avoid oil stains hardening).

二、安装注意事项：细节决定排烟效果

2、 Installation precautions: Details determine the smoke exhaust effect

管道走向：排烟管道应尽量减少直角转弯，每处转弯的角度不小于 120°，避免油烟在管道内滞留，管道长度控制在 15 米以内，过长会导致吸力衰减。

Pipeline direction: The smoke exhaust pipeline should minimize right angle turns, with each turn angle not less than 120 °, to avoid oil fumes from being trapped in the pipeline. The length of the pipeline should be controlled within 15 meters, as excessive length can cause suction attenuation.

风机位置：风机最好安装在屋顶或户外，远离厨房操作区，减少噪音影响，同时风机的进风口与排烟罩的吸风口管径一致，避免因管径变细导致吸力下降。

Fan location: It is best to install the fan on the roof or outdoors, away from the kitchen operating area, to reduce noise impact. At the same time, the inlet diameter of the fan should be consistent with the suction diameter of the smoke hood to avoid a decrease in suction due to a smaller diameter.
