Desert and low humidity... look into evaporative cooling. Water, pump, wet pad and fan and you are good to go!
I read that they got ~25c constant in mining farms in china with this style cooling! In the desert!
Hvac for miners has to be few times larger than for simple home use... not really worth!
Meh, not worth it when the temp outside is 115f. I have a portable evaporative cooler but they only lower the temp 5-15 degrees Fahrenheit below the ambient temp. Everything gets shutdown on the first day it hits 90f.
