How to dissipate heat when the outdoor air conditioner is packaged into a billboard

It is feasible to install an exhaust fan to improve ventilation around the outdoor unit.
Just installing an exhaust fan in this way is equivalent to "adding salt when there is too much water, and adding water when there is too much salt", forming a vicious cycle; and the effect of installing an exhaust fan to improve ventilation is inherently limited.
If possible, it is recommended to change the installation position of the outdoor unit of the air conditioner to fundamentally solve the problem.

It is not suitable for inkjet printing and air conditioning in advertising shops.
For some large-scale advertising inkjet paintings, there are usually lights in them to achieve heat dissipation. In addition, some billboards are equipped with LED screens, which will automatically shut down if the heat is too high. In order to achieve faster heat dissipation, air conditioners are usually installed.
However, generally speaking, advertising shop printing is not suitable for installing air conditioners. Because the area for advertising printing is usually larger, more materials are needed, and the use and maintenance costs of air conditioning are higher, which is not economical.
In addition, if advertising printing is done outdoors, you may encounter uncontrollable factors such as temperature and humidity. In this case, installing air conditioning cannot completely solve all problems.
