1、 Use environmental protection air conditioning for cooling: Generally speaking, environmental protection air conditioning is suitable for large workshops. This kind of workshop has more employees and more complex equipment, which will generate more heat during production. Therefore, environmental protection air conditioning is generally used in this kind of workshop during the cooling process. Because it has the advantages of good cooling effect and fast cooling. However, there are still some shortcomings in the use of environmental air conditioning, because the investment of environmental air conditioning is very large, and the operating cost is also very high. If the air is not circulated in time, the air quality will be worse.
2、 Use cooling water curtain for cooling: secondly, wet curtain can also be used for cooling, also known as cooling water curtain, which is the purpose of water evaporation principle to help cooling on site. This method has the advantages of low investment cost, no pollution and low operation cost, and does not hinder the normal circulation of air. But there are also some shortcomings, the effect of cooling water curtain is very general, the cooling range is very small. Therefore, this method is very suitable for small factories, and the wet curtain can not be used if the scope is too large.
