The kitchen ventilation and smoke exhaust system is now an indispensable equipment in every hotel kitchen. Because the kitchen ventilation and smoke exhaust system for improving the working environment of the kitchen, improve the efficiency of the kitchen, has a very important role. But many people reflect that the kitchen ventilation and smoke exhaust system is not particularly easy to use, kitchen ventilation and smoke exhaust system life is particularly short, about a year is not very good to use. The following edition will give you an analysis of the specific problems of kitchen ventilation and smoke exhaust system and the corresponding treatment methods.

　　廚房通風(fēng)排煙系統(tǒng)老出問題？絲毫不慌，這里有辦法！

　　Is there a problem with the kitchen ventilation and smoke exhaust system? There's nothing to worry about. Here's a way!

　　問題一：廚房通風(fēng)工程中排煙風(fēng)機(jī)、油煙凈化設(shè)備的用電量大，排風(fēng)機(jī)抽風(fēng)實(shí)際效果不太好。

　　Problem 1: In the kitchen ventilation project, the power consumption of exhaust fan and oil fume purification equipment is large, and the actual effect of exhaust fan is not good.

　　原因：整體廚房全部的排風(fēng)罩管道終都集中到一個(gè)通風(fēng)風(fēng)管大系統(tǒng)中，用一臺(tái)大的油煙凈化設(shè)備及一臺(tái)大型排風(fēng)機(jī)排風(fēng)。結(jié)果廚房如果有一個(gè)灶使用，排煙風(fēng)機(jī)、油煙凈化器就得開。這樣一來不僅排風(fēng)機(jī)排煙作用欠佳，并且電耗很大。在酒店中，全年度廚房通風(fēng)用電量約占全年度總使用量的2.8%。

　　Reason: The whole kitchen exhaust hood ducts are eventually concentrated in a large ventilation duct system, with a large soot purification equipment and a large exhaust fan exhaust. Result If a kitchen stove is used, the exhaust fan and the lampblack purifier must be turned on. In this way, not only the exhaust fan smoke exhaust function is not good, but also the power consumption is very large. In high-end hotels, the annual kitchen ventilation power consumption accounts for about 2.8% of the total annual use.

　　處理辦法：按真實(shí)情況分為兩、三個(gè)系統(tǒng)，或選用變速排風(fēng)機(jī)，在高峰負(fù)載時(shí)全開。廚房爐灶使用的高峰期時(shí)間段約為4~5小時(shí)，而其他時(shí)間段為生產(chǎn)加工及提前準(zhǔn)備或衛(wèi)生管理時(shí)間，無需大的排風(fēng)量。

　　Solution: According to the actual situation, it can be divided into two or three systems, or variable speed exhaust fan is selected to be fully opened at peak load. The peak period of kitchen stove use is about 4 to 5 hours, while other periods are production, processing and preparation in advance or hygiene management time, without large exhaust volume.

　　問題二：酒店廚房的送風(fēng)系統(tǒng)選用的是下列幾類方法 ：

　　Question 2: The following types of methods are selected for the air supply system in the hotel kitchen:

　　1、空氣處理方式用了一部分回風(fēng)；

　　1. A part of air return is used for air treatment.

　　2、選用了風(fēng)機(jī)盤管；

　　2. Fan coil unit is selected.

　　3、酒店廚房內(nèi)不設(shè)送風(fēng)系統(tǒng)，只是設(shè)了單體工業(yè)冷風(fēng)機(jī)。使用沒到1年就效率大減，使酒店廚房環(huán)境溫度太高。

　　3. There is no air supply system in the kitchen of the hotel, but a single industrial air-conditioner. In less than a year of use, the efficiency of the hotel kitchen is greatly reduced, which makes the environment temperature of the hotel kitchen too high.

　　原因：這些機(jī)器設(shè)備自身均有水冷式表層冷卻器或直接蒸發(fā)式表層冷卻器。酒店廚房內(nèi)的氣體直接與冷卻器接觸，油霧迅速就會(huì)污染和阻塞表冷器上翅片的空隙，使其排風(fēng)量大減，導(dǎo)致酒店廚房內(nèi)環(huán)境溫度太高，實(shí)際效果差。

　　Reason: These machines and equipments have water-cooled surface coolers or direct evaporative surface coolers. The gas in the hotel kitchen directly contacts with the cooler, and the oil mist will quickly pollute and block the air gap of the fins on the surface cooler, which will greatly reduce the exhaust air volume, resulting in the hotel kitchen environment temperature is too high, and the actual effect is poor.

　　處理辦法：在酒店廚房的送新風(fēng)系統(tǒng)中，不可以用回風(fēng)。只有用直流式系統(tǒng)。根據(jù)戶外前提條件還可以用直流空調(diào)系統(tǒng)，也可為直流送風(fēng)系統(tǒng)。窗式或柜式空調(diào)器在酒店廚房內(nèi)不適合選用。

　　Solution: In the fresh air supply system of hotel kitchen, return air can not be used. Only DC system is used. According to the outdoor conditions, it can also be used as a DC air conditioning system or a DC air supply system. Window or cabinet air conditioners are not suitable for use in Hotel kitchens.

　　問題三：廚房用風(fēng)機(jī)盤管減溫不成功。酒店廚房內(nèi)設(shè)有爐灶排氣系統(tǒng)及新風(fēng)增補(bǔ)系統(tǒng)，還有風(fēng)機(jī)盤管減溫系統(tǒng)。剛建成投產(chǎn)時(shí)，實(shí)際效果挺不錯(cuò)，1年過后，環(huán)境溫度降不下來，有時(shí)候達(dá)35℃以上，工作人員無法忍受。

　　Question 3: Cooling with fan coil unit in kitchen is unsuccessful. The hotel kitchen is equipped with stove exhaust system and fresh air supplement system, as well as fan coil cooling system. When it was built and put into operation, the actual effect was quite good. After one year, the ambient temperature could not fall down. Sometimes it was above 35 degrees Celsius, and the staff could not bear it.

　　原因：經(jīng)檢驗(yàn)了解，發(fā)現(xiàn)酒店廚房內(nèi)油霧、水蒸汽均大，特別是煤氣燃燒后的廚房油煙黏附在風(fēng)機(jī)盤管表面層，使其傳熱系數(shù)大大的降低，制冷效果愈來愈差。

　　Reasons: After inspection, it is found that the oil mist and water vapor in the kitchen of the hotel are large, especially the kitchen oil fume after gas combustion adheres to the surface layer of the fan coil, which greatly reduces the heat transfer coefficient and makes the refrigeration effect worse and worse.

　　處理辦法：將風(fēng)機(jī)盤管在廚房內(nèi)的回風(fēng)口堵上，再用管道將餐廳的空氣引作酒店廚房風(fēng)機(jī)盤管的回風(fēng)，同時(shí)減小戶外空氣的送入量。（廚房裝修設(shè)計(jì)時(shí)不能選用風(fēng)機(jī)盤管系統(tǒng)）

　　Solution: Block the fan coil unit on the return air outlet in the kitchen, then use the pipeline to lead the restaurant air to the return air of the fan coil unit in the kitchen of the hotel, and reduce the outdoor air inflow at the same time. (Fan coil unit system should not be used in kitchen decoration design)

　　上述內(nèi)容就是廚房通風(fēng)排煙系統(tǒng)可能會(huì)出現(xiàn)的幾種問題情況，以及所對(duì)應(yīng)的處理辦法。廚房通風(fēng)排煙系統(tǒng)對(duì)于廚房來說必不可少。大家要是在挑選廚房中培訓(xùn)的時(shí)候，一定要注意細(xì)節(jié)問題，因?yàn)閺N房通風(fēng)排煙系統(tǒng)大的功能就是實(shí)用，所以大家一定要擦亮眼睛，防止被騙。
