I live in a high humidity (75%) climate.
I wanted to know what happens when you combine a light humidifier with a normal AC set on "dry" mode.
The AC is activity reducing humidity, which helps me "feel" cool since water evaporates better off your body.
However, I wonder if I can reduce my energy bill by running evaporative cooling using "cold" new water ( not the water collected by the AC ).
In dries climate you use swamp cooler to reduce the temperature.
The idea here is ( if laws of thermo is obeyed ) is the water leaving the air con unit has some residual heat.
As the air gets dries it gets less efficient for the AC to reduce the temperature.
Each watt of energy gets rid of fewer BTU as the air gets drier.
It's important to note that as you add normal water mist to your room, it evaporates and absorbs heat itself.
As this vapor moves to the AC, you need very little energy ( dew point ) to turn it back to water.
The water contains extra heat that gets removed through the drain pipe.
Without this extra mist humidity, the AC would pump the heat through its internal refrigerant.
The idea here is not to replace a normal AC - a swamp cooler doesn't help in 80% humidity.
The idea here it to enhance the efficiency of a normal AC, even if it helps by 5% thats huge energy saving.
