I have seen a video with no details about someone who turned an old outdoor unit to cool the water in an evaporative cooler. they submerged the copper pipe that carry the refrigerant inside the water, here is the video: youtube.com/watch?v=uUxJsqDyNTQ

how can I achieve that in my central evaporative cooler, which looks very similar to the one in the video?

I have an old 18k split system and I have 2meter copper pipe and a refrigerant tank. what I don't understand is what do I do with the wiring and the indoor unit.

If your cooler is sized properly and maintained well, I see no cost/benefit in doing this. Try putting ice in the sump to see if performance improves enough to warrant the cost of installing and running a 1.5 ton condensing unit along with the cooler itself. I would think 1.5 tons is way oversized too.

About the only good think I can say about doing that is, it would be easy to find an evaporator coil leak. Otherwise, don't waste your time, you need to put your creative talents to work elsewhere. :vs_cool:

for few years people have reported huge improvement when they used this method.

what if we forget the evaporative cooler part. what are the steps so i can use an old split system to cool water in 60L tank by submerging the copper pipes into the tank?

First thing to do would be to make a submersible evaporator. The video linked below shows one way to do that. I'm not sure what length/size copper you would need but think you will need more than 2 meters. I would also think about directly cooling the water in the sump by makiing a flat serpentine coil layout, this eliminates the 60L tank a simplifies things. A thermostatic expansion valve will be needed too. What are the dimensions of the sump and depth of water in it? Let us know how it goes, good luck.

Thanks for the video!
so what about the rest of the indoor unit? i don't need the blower but what about the sensor and the controller (in this ac its not a remote control but a wired one)?
