exhaust fan and smoke purification equipment in kitchen ventilation project!

all the universal exhaust hoods in the kitchen are concentrated in large and medium-sized ventilation duct systems, and the oil fume purifier and large exhaust fan are used for the exhaust pipes. therefore, if there is a stove in the restaurant kitchen, the exhaust fan and fume purification equipment need to be turned on. in this way, the exhaust fan exhaust pipe not only has poor function but also uses a large amount of electricity. in a good hotel, the annual energy consumption of natural ventilation at home accounts for 2.8 of the total annual dose of the total dose in the home ％。

solution: according to the plan, divide it into two or three systems, or choose a speed-regulating exhaust fan, and turn it on completely during peak loading. the high incidence period of kitchen stoves is about 4 to 5 h， but other time ranges are the length of production and preparation or sanitation system, without much displacement.

the gas supply system in hotel kitchens is used as follows:

air treatment method uses part of the return air;

2.choose coil fan;

3.the hotel kitchen does not have an air supply system, only an industrially produced radiator fan. after one year of application, the high efficiency will be greatly reduced, making the natural environment temperature of the hotel kitchen too high.

because of this kind of equipment has its own water-cooled heat-sinking surface cooler or direct volatile surface cooler. when the hotel kitchen gas touches the cooler directly, welding smoke will quickly pollute the environment and block the gap between the radiator on the gas cooler, thereby greatly reducing the displacement, causing the natural ambient temperature to be too high. the hotel restaurant kitchen is expected to have poor results.

solution: in the fresh air system system in the hotel kitchen, you cannot use the air supply. only dc system is applied. depending on the premise of outdoor use, a dc air conditioning system or a dc air supply system can also be used. window or kitchen cabinet air conditioning is not suitable for hotel and restaurant kitchen applications.
