You can just use a swamp cooler.
Let almost all the mineral build up and corrosion happen to the swamp cooler.
BUT it only really works if you have a mechanical txv and will work amazingly if you have a txv and variable speed compressor.

Where would a swamp cooler be installed?

So you are saying run the refrigerant through the condenser and then through a swamp cooler to cool it further?

What is a txv?

You want to build a swamp cooler for the condenser or have the air vents blow through a swamp cooler?

A TXV is a thermal expansion valve. Basically it is a valve that restricts the flow of refrigerant through the system to create a pressure difference between the high and low side of the system, which is what makes it work. How far it is open is controlled by the temperature of the return refrigerant. As it gets colder, it closes to reduce refrigerant flow.

The alternative is a fixed orifice, which is basically nothing more than a small hole that the refrigerant passes through to restrict its flow. A TXV is a better design because it can adjust itself to optimize the system's performance under a wider range of conditions than a simple fixed orifice can. Also, systems with a TXV don't tend to cycle the compressor as much.

Since a TXV is a variable valve that constantly adjusts itself to get the most performance and efficiency out of the system under the conditions its operating in, they tend to respond better to lower ambient conditions (or simulating a lower ambient by spraying the condenser with water) than a system with a fixed orifice would. I hope this helps

Thank you for the clarification.

My car has a thermal expansion valve.

I was not aware of the abbreviation. TEV would have made more sense to me.

Cool, glad I was able to help. I agree that TEV would be a better abbreviation. If you really want to confuse someone though, you can call it a CSV- Constant superheat valve

That is a commercial system that increases the efficiency of A/C systems by using evaporative cooling by means of water misting the intake air.


Here is an educated discussion on the matter:
https://hvac-talk.com/vbb/showthread...condenser-unit


The main concearn is rusting the coils and getting mineral deposits.

The key point seems to be having the spray as far away from the condenser as possible.

Shouldn’t automotive systems be more resilient ot road grime and debris gathering on the condenser.
not with distilled water there is no gases in the water. that is why they insta boil when you drop a sugar cube in super heated distilled water

Do you mean minerals?

Because i am pretty sure distilled water contains nitrogen and oxygen in it.

Our bodies contain about 1.5 liters of nitrogen gas dissolved in the blood and tissues.

no distilled water does not boil because there is nothing to cause it to happen

it's straight h2o..

if it had nitrogen and oxygen (dissolved gases ) it would boil..those are called impurities .. like co2 makes bubbles in soda it has dissolved co2 gas..




your car cooling system uses distilled water mixed with coolant so if it's safe for the inside it's safe for the out side


(i would worry about scale building up and decreasing the efficiency of the cooling unit if TAP water is used)
