Tech Ingredients on YouTube built a dessicant-based air conditioning system with enough info to DIY one. link and a full-scale test ▶ this video
An evaporative cooling solution by "Tech Ingredients" seems to be more efficient (correct me if I am wrong) [0] ▶ this video
TechIngredients did an interesting design for a swamp cooler using liquid desiccants: ▶ this video Haven't yet built one myself, but it looks like a sensible design for climates that aren't overly humid.
