@txag70 Not really. It's almost a zero-sum game since the fridge unit is on the inside as well.

IMHO an Evaporation cooler is far more efficient since when water goes from liquid to gas it ties up a lot of energy. Putting your fan behind an ovenpan filled with water probably the easiest solution and it's pretty effective (more advanced versions can lower the temperature by about 10 degrees Celsius). Really effective unless it's really humid.
