How to calculate fan air volume

Air volume refers to the total volume of air sent or inhaled by the air-cooled radiator fan per minute. If calculated in cubic feet, the unit is CFM; if calculated in cubic meters, it is CMM. which is often used in radiator products. The unit of air volume is CFM.

Calculation formula: N=V×n/Q?

1. N——number of fans (units); V——volume of the site (m3——air); exchange Number of times (times/hour); Q——The air volume of a single unit of the selected fan model (m3/h).

2. Air volume refers to the total volume of air sent or inhaled by the air-cooled radiator fan per minute. If calculated in cubic feet, the unit is CFM; is the CMM radiator. The unit of air volume often used for products is the CFM.

Detailed information:

When the heat sink material is the same, the air volume is the indicator le most important for measuring the heat dissipation capacity of air. -cooled radiator. Obviously, a radiator with a larger air volume has a higher heat dissipation capacity. Indeed, the heat capacity of air is fixed and a larger volume of air, that is to say more air per unit of time, can dissipate more heat. Of course, the heat dissipation effect under the same volume of air is related to the wind flow pattern.

The volume of air circulation per unit time includes other subdivisions such as the volume of air supply and the volume of fresh air:

The volume of Air supply is used to indicate the capacity of ventilation equipment such as fans, and the unit is cubic m/s.

Fresh air volume refers to the total amount of indoor fresh air.

Fans can be classified into several types, such as negative pressure fansve, water air conditioners, water curtains, roof fans and other downward ventilation and cooling equipment. For now, it depends on which way you choose. Today I will briefly talk about several methods for cooling the workshop, I hope it will be useful to everyone.

The negative pressure fan mainly uses the cooling principle of air convection and negative pressure ventilation to work. The door or window in front of the installation site naturally inhales fresh air and quickly exhausts indoor air to the outside (This ventilation and cooling equipment is very good and is now widely used in various workshops and factories .It is favored by many customers and is worth recommending).

The air cooler mainly uses ground water to operate. In summer a water pump is usedused to pump the water and pass it through the inner fan plate to achieve the cooling purpose.
