厨房通风排烟系统现在是每一个酒店厨房里必不可少的设备。因为厨房通风排烟系统对于改善厨房工作环境，提高厨房工作效率，具有极为重要的作用。但是好多人反映厨房通风排烟系统并不是特别好用，厨房通风排烟系统的使用寿命特别短，大约一年就不太好用了。下面小编就给大家分析一下厨房通风排烟系统的具体问题以及相对应的处理办法。
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.
厨房通风排烟系统老出问题？丝毫不慌，这里有办法！
Is there a problem with the kitchen ventilation and smoke exhaust system? There's nothing to worry about. Here's a way!
问题一：厨房通风工程中排烟风机、油烟净化设备的用电量大，排风机抽风实际效果不太好。
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：整体厨房全部的排风罩管道终都集中到一个通风风管大系统中，用一台大的油烟净化设备及一台大型排风机排风。结果厨房如果有一个灶使用，排烟风机、油烟净化器就得开。这样一来不仅排风机排烟作用欠佳，并且电耗很大。在酒店中，全年度厨房通风用电量约占全年度总使用量的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.
处理办法：按真实情况分为两、三个系统，或选用变速排风机，在高峰负载时全开。厨房炉灶使用的高峰期时间段约为4~5小时，而其他时间段为生产加工及提前准备或卫生管理时间，无需大的排风量。
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.
问题二：酒店厨房的送风系统选用的是下列几类方法 ：
Question 2: The following types of methods are selected for the air supply system in the hotel kitchen:
1、空气处理方式用了一部分回风；
1. A part of air return is used for air treatment.
2、选用了风机盘管；
2. Fan coil unit is selected.
3、酒店厨房内不设送风系统，只是设了单体工业冷风机。使用没到1年就效率大减，使酒店厨房环境温度太高。
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：这些机器设备自身均有水冷式表层冷却器或直接蒸发式表层冷却器。酒店厨房内的气体直接与冷却器接触，油雾迅速就会污染和阻塞表冷器上翅片的空隙，使其排风量大减，导致酒店厨房内环境温度太高，实际效果差。
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.
处理办法：在酒店厨房的送新风系统中，不可以用回风。只有用直流式系统。根据户外前提条件还可以用直流空调系统，也可为直流送风系统。窗式或柜式空调器在酒店厨房内不适合选用。
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.
问题三：厨房用风机盘管减温不成功。酒店厨房内设有炉灶排气系统及新风增补系统，还有风机盘管减温系统。刚建成投产时，实际效果挺不错，1年过后，环境温度降不下来，有时候达35℃以上，工作人员无法忍受。
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：经检验了解，发现酒店厨房内油雾、水蒸汽均大，特别是煤气燃烧后的厨房油烟黏附在风机盘管表面层，使其传热系数大大的降低，制冷效果愈来愈差。
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.
处理办法：将风机盘管在厨房内的回风口堵上，再用管道将餐厅的空气引作酒店厨房风机盘管的回风，同时减小户外空气的送入量。（厨房装修设计时不能选用风机盘管系统）
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)
上述内容就是厨房通风排烟系统可能会出现的几种问题情况，以及所对应的处理办法。厨房通风排烟系统对于厨房来说必不可少。大家要是在挑选厨房中培训的时候，一定要注意细节问题，因为厨房通风排烟系统大的功能就是实用，所以大家一定要擦亮眼睛，防止被骗。
