Can you keep the living space from being damp and muggy like a cave or poorly constructed basement?
Cooling with moist outside air will usually result in dampness and for that reason dwellings in warm, moist climates will need some means for removing moisture from the inside air. There are many ways of dehumidifying. Refrigerated air cooling is the least efficient in terms of resources. Better methods are refrigerated dehumidification (about twice as efficient as refrigerated air conditioning) and the many desiccant systems.
