Stitch together the panels’ left sides, then stitch the right side of the other panel to the main body’s right side. Fold up the main body to bring its bottom corners to the side panels’ top corners, then stitch the edges to create a rough bag shape. An air cooler is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor compression refrigeration cycles. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat from the air to evaporate. The temperature of the air can be dropped significantly through the phase transition of water to water vapor.
Pull up the bottom, and flip all of the material right-side out. Laminated cotton, PUL lining, and vinyl are your best options for waterproof materials. If you want to stick with recycled materials, you could use a plastic tablecloth or a plastic shower curtain.
Step 4: Fill Bottles With Ice Cubes
We recommend that you either use soft drink or mineral water bottles. Just make sure that the material of the bottle isn’t too thin or too thick. Thin material will start to melt quickly, and venting holes in thick material would become challenging. Here, a compact fan is mounted face down into a bucket lid, alongside two short lengths of pipe. The pipes can be secured with hot glue or expanding foam, or even bathroom sealant.
Use craft foam boards or sheets of foam board insulation. Measure the box’s bottom and sides, cut a panel that matches the box’s bottom, and make the side panels 2 in (5.1 cm) shorter than the box. Air cooler has required water as the basic coolant, the video below shows you how you can make air cooler and needs coolant such as water. Building a walk-in cooler is a complicated process, but it's possible to construct one yourself if you plan carefully. The team at Sow the Land shares a tutorial on how to build a walk-in cooler using information from the CoolBot website. This example room measures 8 feet by 7 feet and is built with wood framing, including an opening for an entry door and one for the cooling unit itself.

While it might not work as a long-term solution, it's a smart stopgap when your air conditioner is down. If you live in areas where heatwaves are rare, a DIY aircon unit will also save you spending big bucks on cooling. Here, two circles are cut into the lid of the cool box.
In (1.3 cm) from the bottom edge of the side panel at its bottom right corner. Then sew the right side panel to the main panel along the pinned edges. In (1.3 cm) lip formed by the sides of the cardboard box. Cut 2 of the strips, then set them over the gaps on parallel sides of the box. Measure the length between the 2 covers, then cut 2 more strips to match that length. In a pinch, fill the gap with packing peanuts, bubble wrap, or Styrofoam.
Ideas for Converting a Closet Into a Wine Cellar
Use disposable plastic bottles for the easiest set-up and clean up. Put the caps back on and shake the bottles to thoroughly mix the salt.Any standard salt you have in your kitchen will work. Once the bottles have completely dried, take a sharp cutter or knife and cut out the crowned area of both bottles.
Perhaps the best way to relate to this is via the use of a swimming pool. That cooling effect that one experiences after coming out of the pool occurs similarly. As dry air blows through the water on your skin, it absorbs some of the water. As this water turns into gas, heat switches from the much higher air temperature to the lower water temperatures. This natural air circulation thus cools the skin area around it. An air cooler uses the most natural way of cooling air by means of evaporation.
Keep the bag flat against the sides of the box, then trim the bag so it’s flush with the top of the box. Seal the box with foil if the lid doesn’t tightly close. Place an ice pack and the items you’re storing into the box, then cover it with the lid. If you used a plastic container, it should seal tightly.
Align the upper right corners of the main panel and second side piece, and pin down their long sides on the right. Thermal batting, which you can find at a craft or fabric store, is the best insulating material. If you're on a budget, you can recycle thin flexible foam or bubble wrap. Thin craft foam or packing foam might work, but the lunch bag will be stiffer. Fill the gaps between the panels with vermiculite or spray foam. Pour vermiculite between the panels, or use spray foam insulation.

Using a lidded box, foil, and recycled packaging materials, you can make a small, simple cooler. For a larger, more effective design, line a cardboard box with foam board. If you need something more portable, you could also sew an insulated lunch bag to keep items cold when you’re on the go. With the summer just around the corner, very soon people will start complaining about the excessive heat. In a bid to mitigate against such summer heat, one social venture in Bangladesh has created the Eco cooler. This simple air coolers are constructed using affordable, used plastic bottles.
If you made a wooden box, you could make a wooden, foam-lined lid and join it to the box with a hinge. Remember to place the longer cover strips across from each other. Attach the foil to the box so the shiny side faces out.
