How can I turn an old split ac outdoor unit into a water tank chiller?
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.
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.

Ok.
An evaporative cooler works on the basis of evaporating water which will absorb heat as it evaporates.
If you were to cool the water that is suppose to evaporate it will cool less because the water has to warm up to be able to evaporate.
What would work is if you cool the water with an airconditioner and spray it on people with a sprinkler rather trying to evaporate it.

I have no idea what that video is about, but that unit in the video looks like a roof top unit. That is not a outdoor unit, but a package unit that has both inside and outside unit of household central AC system.
I don't quiet understand what you are trying to cool. Evaporative cooler uses evaporating vapor (usually water) to cool the condenser or air. I don't see any reason to use another AC to cool this water.

Welcome to our forums!
What you propose to do on the surface looks like a good idea but in practice would be pointless.
An evaporative cooler works on the principle that as water evaporates it removes heat from the air.
It is the act of evaporation that removes heat and trying to used chilled water to do this might lower the air temperature a minuscule amount, it would slow down the evaporative effect of the water ,cancelling each other out.
What would work is to use that mechanical air conditioner to work as designed by circulating air through the evaporator coil.

Here's a crazy idea. Why not use the air conditioner to help cool the air inside the house instead of hacking it apart to cool water sitting outside in the sun.

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?
There is no way to cool if you only have outside condenser unit.

people have reported huge improvements when they used this exact method.
The the benefit of your idea escapes me and I do HVAC for a living.
You really need to consult those who you are referring to in the above quote.

the climate here is merciless in the summer and for several years people have reported huge improvements when they used this exact 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?

Submerge evaporator coil (inside unit) inside tank holding water.

Every single person has said your idea is not a sound plan and explained why. Do you continue to post trying to convince us or do you have a question we can help you with?
