Specifications for ventilation design and equipment installation in staff canteen kitchens

Installation precautions 1. Anti-leakage measures must be taken at the joints of each air duct. To ensure the purification efficiency of the equipment. 2. The variable diameter air duct connected to the air inlet and outlet of the equipment should be as smooth as possible. To ensure the purification efficiency of the equipment. A straight pipe with a length of more than 4 times the pipe diameter must be installed, and a smooth pipe must be used to connect. Therefore, soft connections must be used when connecting the air ducts of the light fan of the equipment. The equipment will not work normally if it is vibrated during operation. 3. To ensure the purification effect, the air volume of the individual fan is assumed to be greater than the planned air volume of the equipment. The equipment must work at the planned air volume. The user can control the fan with a frequency converter or install an air regulating valve device at the fan outlet to achieve this. 4. To reduce the additional resistance of the fan. It is best to keep a 1-2 meter straight pipe section at the inlet of the fan. 5. The equipment should work in a negative wind pressure state. To ensure the infection efficiency of the equipment. That is, the fan must be located in front of the equipment. 6. When the air is exhausted by a unified exhaust fan, when multiple devices are used in parallel. It is also necessary to ensure that the proportion of air volume allocated to each device is close to the proportion of air volume it intends to handle. 7. Rainproof and sunshade awnings should be installed when installed outdoors. Avoid affecting the normal operating life of the equipment and increasing unnecessary maintenance costs. Maintenance knowledge of range hoods: You may use range hoods in the kitchen every day. Have you ever encountered the situation of excessive noise and vibration of the range hood, oil fume cannot be extracted, and oil dripping and leaking during use? We specially introduce some basic common sense of use and maintenance to consumers: 1. The installation height of the range hood must be appropriate, so that it can not only ensure that it does not hit your head, but also ensure the effect of oil fume extraction. 2. In order to avoid excessive noise or vibration of the range hood, oil dripping, oil leakage, etc., we should clean the range hood regularly to prevent the motor, turbine and the inner surface of the range hood from sticking too much oil. 3. When using the range hood, keep the air in the kitchen circulated, so as to prevent the air in the kitchen from forming negative pressure and ensure the suction capacity of the range hood. 4. Consumers are advised not to disassemble the range hood for cleaning without authorization, because if the motor is not installed properly, the smoke extraction effect cannot be guaranteed and the noise will increase; it is best to let the manufacturer's professionals do the cleaning.
