Detailed Product Description: | In view of the adverse effects on the kitchen staff, hotel kitchen fumes from gas, you need to design from the fronts, the rational design of kitchen air conditioning systems. Use most of the hotel kitchen ventilation and cooling efficiency is very low, structural improvements to increase efficiency, ensure the use of functions, while achieving the goal of environmental protection and energy saving: Contact Mr. Qiu 13,695,004,203 ① hotel kitchen ventilation and cooling of the local air and general ventilation, air distribution more reasonable and effective in improving the working environment of the kitchen staff. The ② selection of direct evaporative cooling ventilators as a kitchen cooling ventilation equipment shall meet the minimum air changes of the design required. ③ should be considered in the selection of the capacity of the exhaust fan to exhaust more than make up air volume to the kitchen to maintain a certain negative pressure to prevent the fumes from the kitchen gas "odor" to the other air-conditioned room. The ④ rational design of exhaust pipe, to prevent potential safety problems. The kitchen of the hotel, is a very important part of the design is usually a weak link, on the one hand, in the design phase of construction drawings, detailed process data are often not related to the kitchen, the program plans to provide building professionals generally only the kitchen area, the height and location of the stove, on the other hand the existing design reference to the lack of specific technical measures, which makes it difficult to determine the kitchen ventilation rate, usually the same kitchen, different design, the results are often different, even disparities, but based on technical measures, but also find their Kitchen ventilation design, therefore, the formation varies from person to person, the situation with no uniform standards, I think the reason for this phenomenon, and we often use "technical measures" in the kitchen ventilation rate determination, the concept does not explicitly require The inconsistency is related to illustrate the problem, we can combine the common Ministry of Construction and Design Institute of the civil HVAC design and technical measures (referred to as "measures") with the relevant provisions in the kitchen ventilation rate to determine the problem. "Measures 4-28 Article: mechanical ventilation, ventilation should be heat balance calculation ... calculation for 65% of the amount of exhaust to the outside through the exhaust hood or screen, while 35% discharged by the full ventilation of the room. In addition, Article 4-26, has stipulated that the wind speed in the mouth of the exhaust hood should be controlled within 0.4 ~ 0.5m / s. "Measures" Article 5.1.3 provides that: ventilation, air-conditioned kitchen mechanical ventilation should be balanced by the heat balance and air flow calculation, when the heat balance calculation is indeed difficult, according to the following two methods in a calculation, and the first method, the preferred method. L1 = 1800 × F1 (F1 to cover the mouth area) L2 = 10 × F2 (F2 for the kitchen area) L = L1 + L2 (L is the total displacement) 2 60 ~ 80 times / ventilation calculation. (the kitchen area of ??less than 50 square meters to take the upper limit, take the lower limit of greater than 50 square meters). Kitchen exhaust should be equivalent to 3 to 5 times / number of times when the ventilation air flow discharge for the full ventilation equipment, but not included in the total air volume. From the provisions of the "measures" measures ", we seem to get an idea around a kitchen ventilation rate calculation. That is, when the exhaust hood in the kitchen, but also there should be other exhaust fan in the same |
