How to calculate the number of industry air cooler required by the plastic factory?

Recently, the weather has been hot. Many customers on the website called for consultation and mentioned such a question. What is the effect of the installation of the industry air cooler?

For such a problem, first of all we have to see what effect you want to achieve?

Example: If you want to reduce the temperature of our 1000 square workshop, if you want to reduce the temperature of the entire 1000 square workshop, then the industry air cooler overall cooling plan is adopted.

The number of industry air cooler installed is determined by the number of air changes in the room. The more air changes per hour, the better its cooling effect, but it also means an increase in installation costs. Now let’s analyze, a 200-square-meter plastic factory installs two industry air cooler with an air volume of 18,000, and the air exchange rate is about 45 times per hour. Assuming that the plastic factory is in a normal working state, the outdoor temperature is about 37°C, and the cold air after being cooled by an industry air cooler is about 27-29°C. Since there are many heat-generating machines in the plastic factory, installing industry air cooler  means that the average temperature in the plastic factory is about 32-34°C. Obviously, this is not an ideal effect.

In this case, if four industry air cooler are installed, the air exchange rate can reach 90 times/hour (this is when the indoor and outdoor air circulation is smooth, if necessary, a negative pressure fan can be installed to promote air circulation). Under the same working environment, the indoor temperature can be reduced to below 30 degrees to achieve the desired effect. The number of installations of industry air cooler is determined according to the heating equipment in the workshop and the area of ​​the workshop. According to our years of installation experience, the general plastic factory area is larger than the workshop of 2000 square meters or more. When there are more plastic machines in the workshop, basically all Choose yes to supply air, and determine the number of industry air cooler to be installed according to the job position.
