Home made Air Conditioner
Hi guys need help designing a little home made air con project. Im trying to go for some thing simple and practical that works .
This is my design bellow .
Its pretty much a foam rectangle with an old 12v condenser fan motor at the front pulling in air from the box. Inside the box are 6 ice plates . which will be 20mm solid ice 3/4 inch .
That i sit in my freezer over night in a mold like thing. The plates are fully inclosed and have salty water inside .
So i can simply take the plates out of the freezer and sit them in the ice box and blow air on me for a few hours.
Theres also a drain that will drain the condensation after about 1 inch , before it touches the bottom of the plates or the fan.
Does that make sense ?
I need a few questions answered .
Would a system like this have much cooling effect? with around 80% RH
What would the air of temp be?
How long would it last?
Should i make the plates thicker or thinner ?
Should i have 2 plates or 4, 5 ? . would 6 really thing ones be better but not last aslong ?
Salt water takes longer to freeze but stays colder longer?
Would i be better of getting a refrigerant gas in a closed loop coil under pressure and shoving that in the freezer?
here are a few designs people have been doing for years . pretty much a fan with a coil, pumping cold water paste it. would this work better than mine or any well at all?
