Need help coming up with the best design for a home made air con.
Reason . Gets really hot here in Australia .
I cant install a split system because im renting i live on the coast so evap coolers dont work.
RAC and portable air cons are expensive to buy and run. If i cant come up with anything better ill resort to this.
Need the design to be low power usage with better cooling effect than a standard fan.
I come up with this last summer

The problem is you have alot of waste heat energy to get to rid of .
Every other home made "air con" Is pretty much a cooler box with ice in it and a fan with a copper coil around it and just pumps the cold water to the fan coil. This is not practical because the ice melts .
All of them pretty much work like this. With ice melting and needing a top up. http://detectenergy.com/wp-content/uploads/2011/04/Homemade-air-conditioner1.jpg

Design 1 .
Under the house is normally 10c to 15c or 50f to 59f temp difference or more after my house heats up and holds in the heat . So i was thinking of running 30metres of clear hose up and down the house on the ground and with a water pump pump it to a modified indoor coil sitting on a table.
Design 2 .
Use a old fridge/freezer to cool water over night and in the morning and have coils of copper inside coiled around a 50mm cylinder of pvc pipe or something for a heat exchanger. Then pump the cool water to a fan and coil .
Or use both these methods .

Do you guys have any better ideas or Any ways i could improve mine .
What would work better ?
Is there an easier way ?
