This project goes over the conversion of an old three way refrigerator unit from an RV into an alternative power offgrid Dual refrigeration system that uses no electric power. This can be really useful in case of a power outage or SHTF situation when you need to keep your food or vegetables fresh.
The first step is to strip the fittings on the back side of the fridge , remove all the ammonia system ,clean the inside of it .
Here we are incorporating more than one way to use this water for cooling refrigeration system to make it efficient .We will be using cooling effect by brining down the water temperature to cool the box , another way to cool the box is by installing an evaporative system. We take the two pipes coming from the water source around the edges of the box and put some cotton sheets around the sides and let the water cascade down the sheet creating an evaporative effect.
We have an inverter and a battery attached to the fridge that is hooked up to a 25W solar panel .The wire from the inverter is connected to 8W Electric Fish tank pump .The water coming from the pump goes underneath and up inside to the lid of the fridge to the condenser coils and then comes back around back into the water source like well or water tank. The full system is recirculated back into the original storage tank where the water is coming from.
We keep the fridge in a chest freezer style instead of an upright style. Inside the fridge, we have incorporated 2 poly tubing coils attached to an old heat sink that was already in the fridge. The 100ft coils are attached to the top of the fridge. The cold from that coils will drop down to the rest of the fridge.
Next step is to incorporate the evaporative cooling part of the refrigeration system. We start by installing aluminum U channels across all the edges of the fridge. The U channel will hold cotton material inside of them. The water coming out of the outputs from our coils rushes into the channel which is going to wick out into the cloth and run down the cloth with gravity, giving us our evaporative cooling effect .
On the corners, we have the U channels interconnected to each other through a bent garden hose in such a way that any extra water flow in the channel can transfer to the the channel that is next.
The cotton sheets are stretched around the box and tuck it down into the channels all the way around under the wires such that the wires will hold the channels up and hold the sheet up inside the channel. To even the flow of the water ,we install a tee. Now the water coming from both sides of the channel can leak into the sheet. Also make sure you have an air gap between the sheet and the refrigerator box.
- DIY Video : How to get Gold from Scrap Computer parts that you can find at the junkyardThis project goes over how you can easily refine and smelt Gold from Old Scrap Computer Memory Chips . The materials you need for this project are some Muriatic acid,Hydrogen peroxide,Urea,Sodium Metabisulfite,Nitric acid. Cut the little gold fingers from the chips using a heavy duty scissors.Get right to the edge of the gold and cut that off. Okay, now that we've got all the fingers cut off of our memory chips, we put them in a plastic container.And in equal parts, we're going to add our hydrogen peroxide and our muriatic acid. Let it sit for 24 hours.If you can put it out in the sunlight during the days or the day time and then bring it back in at night,that's ideal. Drain the mix through a coffee filter and into another plastic container. And then we will rinse distilled water in these fingers and go through each one of the fingers and make sure there isn't any gold left on them. Filter the Gold granule filled water using a coffee filter,add sprinkles of distilled water.This helps to move those tiny granules around. Add some nitric acid and muriatic acid to the gold mix and put it on a hot plate or a coffeemaker and turn it low.Let that gold dissolve into the mixture. Strain the mixture through a coffee filter and rinse them though distilled water and put it on a burner. Now we are going to add Urea. Basically what the urea is going to do is neutralize the acid, we're going to start with one tablespoon of this, and then keep adding it stops bubbling that's all the acid neutralizing right there. Now we're going to add our sodium metal by sulfate, we're going to add two teaspoons of that. And that's going to turn all that liquid gold into metal. Let the mixture sit overnight and let it settle down.Everything on the bottom is going to be our gold, and it's going to be ready to smelt. Heat them till its melted and upon weighing its around 1.91 grams. Next step is testing the gold we have produced and see how pure it is. We use different acids based on the karat.If there is no reaction from the acid test,ifit's not changing colors, and it's not dissolving ,then we have a pure 22 or 24 karat gold here. If you follow this process, you will be able to convert all of your old and outdated computer chips into pure gold that you can turn around and sell for money. It’s a great way to salvage your old electronics and get some value out of them. https://www.youtube.com/watch?v=8lXd85YfcvY https://www.youtube.com/watch?v=5c9Z5UYsUV4 https://www.youtube.com/watch?v=qkmhEGBjyMs
- DIY Video:How To Turn Your Old Fan Into An Airconditioner AC for cheap.This project shows you how can take an old table fan and convert it into a simple ,cheap and easy to make homemade AC . The materials needed for the this project are a table fan, 75 gallon per hour fountain pump with valve to control the water flow, multi purpose zip ties ,two 3/8th inch transparent PVC Pipe tube, 15 foot quarter inch copper tube,two hose clamps. Unhook the locks if any and remove the screen of the fan. Take the copper coil and wind them across the rims of the fan .Secure them tight on the screen using multi purpose ties. Add the screen back to the fan body and then adjust the two ends of the copper coil by bending them to face the back of the fan and secure them using ties. Two 3/8 transparent vinyl PVC pipes are connected to the copper tube ends using hose clamps. We attach the fountain pump to the end of the vinyl PVC tube that goes straight into our cooler. The recirculated water coming from the other end of the tube goes straight back into the cooler bag. The cooler bag is filled with ice packs and water. The water pump is submerged into the bottom of the bag with ice and water over it. The water which is pumped with the help of the fountain pump gets recycled through the vinyl and the copper pipe and moves back into the bag, so you dont need to add more water .Both the pump and fan can be connected to solar generator in case if you want to make the system portable . https://www.youtube.com/watch?v=5NuvzWaBulw
