Introduction: "Solar" Air Conditioning

*Note* This project is done by students from Singapore Polytechnic.
"Solar" Air Conditioning

Components used : 
2x BIG DC fan
1x Aquarium pump (preferably DC pump)
1x CPU Heatsink
1x copper pipe
1x polystyrene ice box
Nx reusable ice pack 
Solar panels (Optional)

The tools and components were provided by our FYP supervisor Teo Shin Jen.

What makes it solar then??? Well, if the Solar panels are used to provide 12v to the dc fan and dc pump in this setup, isn’t that “solar air conditioning”.

Chill the ice packs.
Design the polystyrene ice box.
Attach the bent copper pipe.
Attach aquarium pump to copper pipe.
Turn on to enjoy!

Step 1: Chill the Ice Pack

Chill the ice packs in the freezer compartment for over 12 hours and place them in the polystyrene ice box.

Step 2: Design the Polystyrene Ice Box

On polystyrene ice box, take the top cover and  make 2 holes to accommodate hot air intake and cool air exhaust DC fans.
Left hand side of this picture is a DC fan with heatsink, drawing hot & humid air into the cold chamber and right hand side of the picture is cool air exhaust.

Step 3: Attach the Bent Copper Pipe

On CPU heat sink attach the bent copper pipe.
Having copper pipes to run icy water circulating through the aluminium heat sink while hot air is being drawn to the chilled metal surface, condensation will occur. The condensed water will then drip into the ice box filled with ice packs and water.

Step 4: Attach Aquarium Pump to Copper Pipe

The connector is modified from a furniture stopper

Step 5: Final Product

    Wouldn't it be more efficient to simply run an air con unit? If you are freezing the water in a freezer first you are simply adding a layer of inefficiency.
