I was thinking evaporative Cooler works like a Car Radiator System , but in reverse.
In a car, the surrounding air is pushed through the radiator grill.
As the air passes through , it absorbs heat from the radiator and the radiator therefore cools down.
And I figure that the absolute minimum possible lowest temperature yhe radiator can drop to is that of the ambient air temperature.
In a Home Cooler, air is passed through a radiator what is hooked up to the plumbing supply.
The ambient air is passed through this radiator and is cooled down and supplied to the room where it is needed.
I figure that the lowest possible temperature the cooled air can reach is the temperature of the water that is in the radiator.
I don't wish to know the workings of evaporative coolers, but just wish to know if that last bit of figuring I done is correct.
