How to Calculate Kitchen Chimney Suction Power and Capacity?

Because the kitchen is the main point of every house, the mood created in the space is highly essential. A variety of factors, such as cooking, smells, waste heat, and other factors, influence the environment in the kitchen. Chimneys are critical in ensuring that the odors, heat, smoke, and other contaminants from the meal are dispersed out of the space.

Chimneys exhaust smoke, heat, odor, and other pollutants via ducts. Chimneys have varying suction powers, which allow them to remove waste heat, particulates, and greasy substances.

After months of continuous usage, the suction force and capacity of a kitchen chimney diminish. Filters that have become ineffective, inadequate maintenance, and other factors have contributed to decreased performance. In such a scenario, the most straightforward solution is to clean filters and verify that they are functioning correctly. However, what if everything seems to be in working order, but there is a problem. An issue with the blower or power supply? For that matter, it would be preferable to calculate the kitchen chimney suction force to figure out the answer.

As a result, the large kitchen necessitates more effort in sucking in air, and the results are predictable when calculating suction power. Therefore, it is necessary to consider the volume of the kitchen and multiply it by specific values to determine the suction power. You may learn how to comprehend it by looking at a basic example.


What is the best way to calculate?

MCPH (meter cube per hour) is the unit of measurement for suction power. The amount of air that the chimney will be able to suck out of the kitchen and hurl out is measured in suction power. The amount of suction force needed does not rely on the size of the household, contrary to popular belief among homeowners.

  • Consider the following scenario: a kitchen with dimensions of 5 × 5 meters. The ceiling wall rises to a height of three meters above the ground. To find out how much space is available, multiply these three figures together.
  • The kitchen has a volume of 5 × 5 x 3 = 75 m3.
  • It means that the suction force needed to remove oily air from your kitchen equals the volume multiplied by ten.
  • 75 m3 x 10 = 750m3/h Suction Power is equal to the kitchen volume multiplied by 10.

This technique will let you determine how much suction force is required for your particular kitchen. Of course, make sure that you always consider the size of the kitchen before deciding on the best one. However, what is the most critical variables that influence suction power? So, let’s have a look at it.


What Factors Influence Suction Power?

Filterless Chimney

Three critical variables influence the suction force and capacity of a kitchen chimney. Considering the following factors may be beneficial in preventing such problems from occurring –

The length of the diameter of the kitchen chimney ducting is essential considerations.

The number of bends in ducting may harm performance.

Cooking practices characterized by a heavy reliance on oil

Anyone may use high suction power kitchen chimneys to eliminate any of the main problems they are experiencing in their home.

The size of the ducting varies from house to house based on the kitchen infrastructure. Long-length ducting requires more effort to extract smoky air; thus, greater suction power is needed. The use of small-diameter ducting makes it challenging to discharge smoke. It is usually preferable to use ducting with a short length but a big diameter.

The number of bends in the ducting pipe increases its time to exhaust smokey air. As a result, wherever possible, minimize the number of bends in ducting installation. The suction force of the chimney in a non-vegetarian kitchen is greater than that of a vegetarian kitchen. When compared to vegetarian cuisine, non-vegetarian food produces more excellent smoke and stink. More suction strength is required to expel more smoke and odor.


Suggestions for Increasing Chimney Suction Power

When your kitchen chimney decreases it suction strength and you want to get rid of the problems that are causing them, it would be a better option to keep the kitchen chimney in good working condition. The following are some essential suggestions that may assist you in increasing the suction force of your chimney:

The kitchen chimney, for the most part, requires a large filter surface. That offers an efficient method to increase the power of your chimney.

A baffle filter is superior to a cassette filter when it comes to improving performance. Oil grease may get trapped within the baffle filter, although this does not affect the chimney’s suction life.

Choosing frequent suction power cleaning is essential if you want to ensure that your suction power lasts at least five years. Cleaning suction power is defined as the ability to capture smoke particles, oil, and odor.

If you seek to build the greatest chimney in your cooking area, various choices are available that provide the most satisfactory performance at an accessible price.

Please don’t take any chances when it comes to chimney maintenance. If you discover a problem with your chimney, you should address it immediately. It contributes to the improvement of the suction force of the chimney.

Following all of the recommendations mentioned above, you will better maintain your kitchen chimney in the future. Bear in mind that you have to clean the kitchen chimney filter and changing it after some time is necessary for efficient operation. It’s easy to avoid any performance issues if you follow the recommendations provided above.


The bottom line

Once you understand the method for calculating the suction power and capacity of a kitchen chimney, you can improve the overall performance of the appliance. If the filters are blocked or any obstruction at the end of the chimney exhaust, there is little question that performance will be reduced. You may use this formula to understand suction power better and keep the chimney in a more efficient state of maintenance.
