Hello Maikol,
I am agree with Desmond and Ockert.
If you observe a performance drop, my first advise would be to clean your fin tube with a good cleaning system if it’s not already done.
If during the year the performance is changing due to hot tempreature, fogging can be a good idea only if:
– relative humidity is low during your hot season (so you can vaporise a lot of water and get the adiabatic reaction which decrease air temperature)
– your hot season is short (it will consume a lot of water!).
I can support you about this 2 subjects, at your disposal 🙂 (ax-system.com).
