How to calculate how many industry air cooler are needed in the workshop. With the development of energy-saving and environmentally-friendly air cooler technology, more and more factories and workshops choose it as their employees’ ventilation and cooling equipment. Many people say how many industry air cooler are needed, just ask a professional salesperson or a professional industry air cooler technician. In fact, before this, you can also learn to calculate how many industry air cooler you need in your own premises.

First of all, we can calculate according to theory. The calculation method is to first calculate the cooling load, wet load and air supply volume of the used area according to the conventional air cooler load calculation formula, and then calculate the total cooling capacity that the industry air cooler can provide, so as to choose energy saving and environmental protection. For the number and model of air cooler, the total cooling capacity of industry air cooler must be greater than the cooling capacity required by the use area, and the remaining capacity can generally be considered 10%.

Theoretical calculation of the total cooling capacity of industry air cooler:

Total cooling capacity S=LρCp{e•(tg-ts)+tn-tg}/3600

in:

L——The actual air supply volume of energy-saving and environmentally friendly air-cooler (m3/h)

Ρ——The density of the air at the outlet (kg/m3)

Cp——Specific heat of air (kJ/kg•K)

E——The saturation efficiency of industry air cooler, generally 85%

(Tg-ts)——Dry and wet bulb temperature difference (℃)

(Tn-tg)——Temperature difference between indoor and outdoor (℃)

Set △t1=(tg-ts), △t2=(tn-tg), where △t1 is a positive value, and △t2 has positive and negative values.

The total cooling capacity S=LρCp(e•△t1+△t2), where ρ, Cp, e are constants. It can be seen that the total cooling capacity of the industry air cooler and the actual air output of the air cooler, the difference between dry and wet bulb temperature, The temperature difference between indoor and outdoor is related. Since △t1 and △t2 are uncertain quantities, they change with the change of the external environment temperature, so the formula of total cooling capacity is generally only used for qualitative analysis, and seldom used for quantitative calculation.

Secondly, we use our experience to calculate the number of equipment based on the characteristics of XIKOO industry air cooler. That is, the number of air changes is used as a parameter to determine the number of industry air cooler required in a certain space. This is a commonly used design method for industry air cooler.
