How much exhaust airflow does a household range hood generally need?

The most suitable air volume for the public flue is 15m3 min, not the bigger the better. And theoretically speaking, the air volume and noise of the fan are a pair of natural contradictions, and the more the air volume is too large, it will cause unbearable noise. The quality of smoking effect can not be judged only by air volume, too large air volume not only can not absorb the fume, but also will disturb the flow direction of the fume gas.

Many side suction machines on the market have a circular port in the middle of the position, claiming 360° air intake. But in fact, the smoke generated by the two stoves of the stove is distributed on both sides, and the smoke in the center can only ensure that the smoke closest to the center area enters in all directions, and the smoke that is far away is easy to escape, so this 360° air inlet is only a 360° open design, and not all the smoke is entered.

Buying tips. The material of the stove and pot stand is a part of the importance that should be taken into account. Try to choose the stove as much as possible to be made of copper, so that the horn structure is easy for us to clean.

Choose an electroplated paint for the pot holder, which will be easier to clean than an uneven iron cast pot holder. At the same time, the cooktop should also choose the kind that is completely closed downward, so that if there is an overflow in cooking, it will be gathered together for easy cleaning.

In addition, choose the kind of kitchen stove that can be timed, so that when it takes a lot of time such as steaming, you can free up time to do other things, and there is no need to keep staring and worrying about exceeding the time. Also, when choosing the ignition method, use electronic ignition, which is more energy-efficient and can be used for a long time without changing the battery.

If you choose a two-burner stove, you need to have different thermal effects on both eyes, so that you can carry out different firepower at the same time. The distance between the two stoves should also be smaller, so that when cooking on a countertop that is usually less than 75cm, it is convenient for the exhaust fan to smoke efficiently.

Studies and tests have shown that the exhaust air volume of household range hoods is most suitable in the range of 15 cubic meters to 18 cubic meters.

Range hood selection principle:

1.Generally speaking, less than 10 cubic meters min minutes are considered to be too small exhaust air volume (excluding 10 cubic meters), it is not recommended to buy, and with the increase of use time, the oil smoke is more unclean after the suction power of the range hood is weakened.

2.When the air volume of the range hood is too large, it will extract the surrounding oxygen and have a certain impact on the flames, and also take away a part of the heat, and at the same time, the exhaust air volume is too large to have certain requirements for the range hood motor, so it increases the size of the noise and affects the comfort of cooking, generally speaking, more than 20 cubic meters are too large exhaust air volume, and it is not recommended to buy.

Range hood exhaust air volume type:

At present, the exhaust air volume of range hoods on the market is 10 cubic meters min, 11-14 cubic meters min, 15-17 cubic meters min, 18-20 cubic meters min, and 21 cubic meters min.

<> kitchen size: Generally speaking, the air volume of the range hood should be able to adapt to the size of the kitchen. It is recommended that the exhaust volume (air volume) per hour should be 8-12 times the area of the kitchen.

For example, if the area of the kitchen is 20 square meters, then the ideal air volume range is 160-240 cubic meters per hour.

Stove power: The air volume of the range hood should also consider the power of the stove. In general, the higher the power of the stove, the greater the air volume of the range hood required. In general, each kilowatt of stove power requires about 100-150 cubic meters of airflow per hour.

Cooking frequency and flavor: If you regularly fry, cook strong spices, or cook dishes with large fumes, then you may need a higher range hood airflow to effectively remove fumes and odors.

Please note that the above is only a general guide and may vary depending on kitchen construction, hob power and personal preference. It is recommended to consult a professional or refer to the product manual before purchasing a range hood to ensure that you choose the right air volume for your kitchen needs.

The kitchen often stir-fries and cooks, and the smoke is relatively large, so it is generally necessary to install a range hood. How much air volume is enough for the range hood? PChouse will take you to find out.

Generally, the exhaust air volume of the range hood is 15 18 cubic meters, which is the best, and it can be said that it is also the most suitable for home use.

When the air volume of the range hood exceeds 15m cubic meter min, and then continue to increase the air volume to improve the smoke exhaust effect does not help, if the air volume is forcibly increased, not only can not smoothly enter the public flue, but also will cause the smoke backflow to reduce the smoke effect, and the accompanying noise roar is even more intolerable. Therefore, after years of research and testing, the exhaust air volume of the range hood chain is the most suitable between 15 cubic meters and 18 cubic meters, if the noise of the range hood is relatively small, it is recommended that the exhaust air volume is as large as possible, but not more than 18 cubic meters.

At present, the exhaust air volume of range hoods on the market is 10 cubic meters min, 11-14 cubic meters min, 15-17 cubic meters min, 18-20 cubic meters min, and 21 cubic meters min.

The general choice of household air volume in 12 15 cubic meters of range hood is enough, if the noise of the range hood is relatively small, it is recommended that the exhaust air volume as large as possible, but not more than 18 cubic meters.

It is not good for the range hood to have too much or too little airflow. When the air volume of the range hood is too large, it will take away the surrounding oxygen, which has a certain impact on the flame, and also takes away a part of the heat. Moreover, the large air volume has certain requirements for the motor of the range hood, so the noise will also increase, affecting the comfort of cooking.

However, Zheng Xingjia shouted that the air volume of the range hood was too small, and the removal speed of the oil smoke was slow, or the oil smoke was not clean.

Summary. Hello, how big is the air volume of the household range hood.

Because increasing the exhaust air volume of the range hood alone will inevitably increase the noise, so the exhaust air volume of the range hood is the most suitable between 15 cubic meters and 18 cubic meters, if the noise of the range hood is relatively small, it is recommended that the exhaust air volume is as large as possible, but do not exceed 18 cubic meters.

How to calculate the exhaust air volume of a household range hood? How to choose the size.

Hello, how much air volume of household range hood is because increasing the size of the exhaust air volume of the range hood alone will inevitably increase the leakage noise, so the exhaust air volume of the range hood is the most suitable between 15 cubic meters and 18 cubic meters, if the noise of the range hood is relatively small, it is recommended that the larger the exhaust air volume, the better, but not more than 18 cubic meters.

How to choose the exhaust air volume of the oil smoke disturbance machine 1, the general kitchen situation is mainly 3-5 square meters, 5-7 square meters, 7-9 square meters, 10 square meters or more of these four areas, can also be divided into open and closed, if you belong to 3 to 9 square closed or open kitchen, you can choose 15 cubic meters. If you belong to more than 10 square open hours, you can choose the cubic exhaust air volume liquid Li Bi range hood. 2. Cooking situationIf there are a large number of people in the family, cooking is very frequent, and it is a dish that likes to stir-fry peppers and heavy tastes, you can choose a range hood with an exhaust volume of 17-20 cubic meters; On the contrary, if you don't usually cook much, and tend to have a light meal, 15 cubic meters is enough.

3. The floor & flue situation of the floor and the length of the flue are the main factors affecting the smell of the fume backfill, the higher the floor where the general residence lives, the more likely it is to backfill, the longer the smoke pipe, the more difficult the smoke exhaust, the suggestion is to choose a 17 or 18 cubic smoke machine, or buy a range hood with automatic pressurization. If it is a self-built house, it can be ignored, and it is recommended to choose 15 cubic meters.

How to calculate the formula?

What formula do you want to calculate.

The larger the rock crack in the kitchen area, the greater the amount of exhaust air required. Generally speaking, the exhaust air volume of the range hood should be more than 300 cubic meters per hour, if the area is larger or the power of the cooker is larger, you can choose a product with a larger exhaust air volume.

If the kitchen is connected to the living room, dining room and other spaces, or the ventilation conditions are poor, you need to choose a range hood with a larger exhaust air volume to ensure that the oil smoke will not pollute the indoor air.

If the kitchen area is small, or the stove power is small, you can choose a range hood with a relatively small exhaust air volume. However, it should be noted that too small exhaust airflow will lead to poor effect of the range hood, and it is recommended to choose an exhaust airflow of at least 200 cubic meters per hour.

It should be noted that the larger the exhaust air volume, the louder the noise of the range hood will be, which will affect the home environment and quality of life. Therefore, when choosing the exhaust air volume, it is necessary to take into account the influence of noise and select the appropriate exhaust air volume.

In general, the selection of the exhaust air volume of the range hood needs to comprehensively consider the kitchen area, stove power, ventilation conditions and other rough posture factors, and choose the appropriate size of the range hood according to the actual situation. If you are not sure what kind of range hood to choose, you can consult a professional or refer to the product manual.

How much displacement to buy a range hood, mainly depends on the use of the environment, the general family use, 30 40 cubic meters of scrambled key flush displacement range hood is enough, if it is used in the catering industry, then according to the needs of the same time, 80 150 cubic meters of displacement is needed to exhaust all the fumes.

When buying a range hood, you need to pay attention to its specific exhaust air volume. What is the general exhaust air volume of the range hood? PCHOUSE will take you to find out as soon as it is sold.

Generally, the exhaust air volume of the range hood is 12 15 cubic meters, which is the best, and it can be said that it is also the most suitable. Wind pressure refers to the exhaust air volume of the range hood reaching 7m?The greater the static pressure value of min, the stronger the anti-wind ability of the range hood and the better the smoke exhaust effect.

If the smoke exhaust pipe is long, far away from the public flue, and on a higher floor, a greater air pressure is required to ensure that the smoke is discharged and prevent the backflow of oil smoke. Generally, the wind pressure of the machine on the market is 300pa, which is also the most suitable!

If there are a large number of people in the family, cooking is very frequent, and you like to stir-fry chili peppers and heavy dishes, you can choose a range hood with an exhaust volume of 17-20 cubic meters; On the contrary, if you don't usually cook much, and tend to have a light meal, 15 cubic meters is enough.

When the air volume of the range hood is too large, it will extract the surrounding oxygen and have a certain impact on the flames, and also take away a part of the heat, and at the same time, the exhaust air volume is too large to have certain requirements for the range hood motor, so it increases the size of the noise and affects the comfort of cooking, generally speaking, more than 20 cubic meters are too large in exhaust air, and it is not recommended to buy.

The exhaust air volume of the range hood is usually determined according to the kitchen area and the power of the stove macro and slow gear. Generally speaking, 300-400 cubic meters of exhaust air-hours are required per square meter of kitchen area, and at least 350-400 cubic meters of exhaust air-hours are required for each stove.

Generally, the exhaust air volume of the range hood is 12 15 cubic meters, which is the best, and it can be said that it is also the most suitable.

The size of the smoke suction ability is still to see how much negative pressure the oil suction allows the smoke to occur in the area of the cooktop, and how large the exhaust air volume is, so that you can see whether its exhaust power is good or not, and it depends on the size of the wind pressure. Theoretically speaking, under the condition that the turbine and inner cavity are reasonably designed, the larger the exhaust air volume, the greater the air pressure of the range hood. So in a sense, the two complement each other, and it can be said that they are inseparable.

Extended Information: Precautions for Using Range Hoods.

Many users in cooking, only a few minutes to turn off the range hood, this can not play its role in the slippery, the correct way to use is as long as the beginning of cooking should be opened, straight to the end of the whole cooking and then pass 5 6 minutes, can be shut down. Due to natural gas or liquefied petroleum gas, in the case of the range hood is out of use, as long as the nitrogen compound is burned for a few minutes, the nitrogen compound will exceed the standard by 5 times, and the carbon monoxide gas can exceed the standard by more than 65 times.

The size of the air volume of the range hood should be determined according to the area and usage of the kitchen. Generally speaking, the larger the exhaust air volume of the range hood, the better the smoke exhaust effect. However, if the exhaust air volume is too large, it will cause energy waste and noise pollution, which is not conducive to environmental protection and health.

Therefore, when choosing a range hood, you need to consider the following aspects:

1.Kitchen area:The exhaust air volume of the range hood should be selected according to the area of the kitchen.

Generally speaking, if the kitchen area is 6-8 square meters, the exhaust air volume of the range hood is about 300-400 cubic meters per hour; The kitchen area is 8-12 square meters, and the exhaust air volume is about 400-500 cubic meters per hour; The kitchen area is more than 12 square meters, and the exhaust air volume is about 500-600 cubic meters per hour.

2.Cooking frequency:If you often cook in the kitchen, or often fry and fry at high temperatures, it is recommended to choose a range hood with a slightly larger exhaust air volume to ensure the smoke exhaust effect.

3.Pipe Length:The length of the exhaust duct of the range hood will also affect the exhaust effect. If the length of the exhaust duct is long, it is recommended to choose a range hood with a slightly larger exhaust air volume to ensure the smoke exhaust effect.

4.Environmental protection and energy saving:When choosing a range hood, environmental protection and energy-saving factors also need to be considered. Some new range hoods adopt intelligent control residual posture branch technology, which can automatically adjust the exhaust air volume according to the cooking situation, which is energy-saving and environmentally friendly.

Anyway:The exhaust air volume of the range hood should be comprehensively considered according to the area of the kitchen, the frequency of cooking, the length of the pipe, and the environmental protection and energy saving, so as to achieve the best smoke exhaust effect and the purpose of energy saving and environmental protection.
