Summer has arrived, and the air doesn’t cool down. What do people do?
1. Perform online cleaning of the air cooler; 2. Find the manufacturer of the air cooler as well as the design documents, and adjust the angle of the air cooler fan blades
If it is a design flaw caused by an increased production load, cooling facilities must be added. If it is a device issue, a maintenance plan should be established in advance.
The cooling efficiency of air coolers is greatly affected by the ambient temperature. They are generally designed based on the average temperature of the hottest month, but their cooling performance tends to be poor during periods of sustained high temperatures in summer. It is possible to consider installing a water spray system below the air cooler; this system can be activated during periods of high temperature, and by using water vaporization to remove a large amount of latent heat of vaporization, it is possible to improve the cooling efficiency of the air cooler. It is recommended to use softened water as the cooling water; desalinated water is even better. The amount of water sprayed does not need to be large.
If the water quality is poor, corrosion and scaling become more severe
Check the opening degree of the louvers to see if there are any debris on the air cooler that could interfere with heat dissipation. Use fresh water to rinse the fin tubes; if that doesn’t work, clean the tube bundle with high-pressure water during maintenance
If online cleaning is not possible, the load can be reduced. If the task of cooling down is urgent and it is not feasible to reduce the load, fresh water can be used through fire hoses to be poured onto the pipe bundles (at the material inlet). Over time scale may form, but this method can provide temporary cooling.
Yes, it is recommended to have certain requirements for water quality.
