The gas collection (smoke) hood is generally processed as a whole, including equipment such as filtering, oil collection, and water collection, and is mostly produced by professional kitchen companies. Its appearance should be uniform, beautiful, and easy to clean. In kitchen ventilation, a certain amount of fresh air needs to be added. On the one hand, it can balance the air pressure and avoid excessive negative pressure in the kitchen (generally not exceeding 5Pa), and on the other hand, it can reduce the temperature inside the kitchen and improve the working environment. For the collection of cooking fumes, there are three main categories of gas collection (smoke) hoods used:

簡(jiǎn)易不含擋油板和送風(fēng)設(shè)備的集氣罩適合各種靈活機(jī)動(dòng)場(chǎng)所，便于加工安裝，便宜。但由于沒有送風(fēng)設(shè)備，集風(fēng)效果相對(duì)較差，容易使油煙在廚房工作人員面前回旋，并且容易造成油滴散落。

The simple gas collection hood without oil baffles and air supply equipment is suitable for various flexible and mobile places, easy to process and install, and cheap in price. However, due to the lack of air supply equipment, the air collection effect is relatively poor, which can easily cause oil fumes to swirl in front of kitchen staff and cause oil droplets to scatter.

含擋油板和送風(fēng)設(shè)備的集氣罩能夠較好地收集烹飪過程產(chǎn)生的油煙，油滴不散落，只要送風(fēng)風(fēng)量合理，廚房操作人員工作面的空氣質(zhì)量就好。但安裝要求較高，投資較大。

The gas collection hood with oil baffle and air supply equipment can effectively collect oil fumes generated during the cooking process, and oil droplets do not scatter. As long as the air supply volume is reasonable, the air quality of the kitchen operator's working face is good. But the installation requirements are high and the investment is large.

運(yùn)水集氣（煙）罩的設(shè)計(jì)原理是形成水幕循環(huán)，與油煙碰撞后達(dá)到凈化油煙的目的。影響運(yùn)水集氣（煙）罩使用效果的關(guān)鍵是要形成連續(xù)的水幕，并需要對(duì)循環(huán)水系統(tǒng)進(jìn)行定期清理。實(shí)際上由于管理不善，目前大部分運(yùn)水集氣（煙）罩無(wú)法形成連續(xù)水幕，而只是形成了斷續(xù)流動(dòng)的水滴或小水柱，因此使用效果非常差。

The design principle of the water transportation and gas collection (smoke) hood is to form a water curtain circulation, which collides with the oil smoke to achieve the purpose of purifying the oil smoke. The key to affecting the effectiveness of the water transportation and gas collection (smoke) hood is to form a continuous water curtain and regularly clean the circulating water system. In fact, due to poor management, most water and gas (smoke) hoods currently cannot form a continuous water curtain, but only form intermittent flowing water droplets or small water columns, resulting in very poor performance.

由于廚房類型的不同，需要定制的排油煙系統(tǒng)也不同，所以這需要的公司來幫助設(shè)計(jì)餐飲廚房排油煙系統(tǒng)，長(zhǎng)沙艾默柯科技有限公司可以為您量身定制商用廚房工程。
