00:00In today's video, we're going to build a homemade air conditioner using very few components.

00:06Stay until the end.

00:17To begin, we'll need a copper tube with a 4 by 6 millimeter diameter.

00:23Using something round like this paint can, we'll bend the copper into a spiral.

00:29What we're creating is a real miniature refrigeration system capable of lowering the air temperature

00:34down to minus 10 degrees Celsius or to chill some drinks in just a few minutes.

00:46Once we have about 8 loops, we proceed to cut the tube and slightly bend the ends so we

00:56can connect them later on.

01:03This tube, thanks to its excellent thermal conductivity, will serve as our evaporator.

01:09Now we're going to create a second circuit with the remaining copper tube.

01:16We'll bend this second tube with a wider spacing and fewer turns.

01:20Will it be the condenser unit?

01:26Now we're going to attach the components to this small wooden structure.

01:50We've already made the holes we'll need, but you can drill them to fit your own parts.

01:57We're going to attach some plastic supports to hold the tubes in place.

02:03First we'll secure the evaporator tube.

02:06A few zip ties will be enough to fasten our conduit.

02:12We insert the zip ties through the supports to hold the tubes.

02:23And then we'll secure the evaporator.

02:44I always love this part of the videos.

02:46The sound of the zip ties fascinates me.

02:52There it is.

02:53Now we're going to secure the condenser.

03:07Pay attention to how the inlet and outlet tubes are oriented.

03:19Now we're going to take a copper tube called a capillary tube.

03:23This small tube will create a sudden pressure drop in the evaporator, which will produce

03:27the cooling effect.

03:31We'll bend it using a pen.

03:33Two or three turns will be enough.

03:47We're going to insert the capillary tube into the end of the condenser and the other side

03:51into the evaporator.

04:01Flatten the two sides to fix the capillary.

04:09To avoid gas leaks, we solder the ends with tin using a soldering iron.

04:21Now that we have the circuit assembled, we're going to add a small and inexpensive 12-volt

04:36fan.

04:39We'll mount it to the base next to the evaporator.

04:47Air will flow through the conduit.

04:51Now we're going to install a small battery holder.

05:04And next to this holder, another one that will support an air pump.

05:11We'll cut a PVC tube into two pieces and connect them to the outlets of the condenser and the

05:22evaporator.

05:23Then we'll place a 12-volt air pump on the previously installed support.

05:41Then we'll place a 12-volt air pump on the previously installed support.

05:48Now we connect the pump outlet to the condenser and the inlet to the evaporator.

06:02And we'll connect both the air pump and the fan to the battery mounted on the wooden base.

06:11and the air pump out the intermediary.

06:12So let's get the pump out of the system.

06:18And then we'll place a 12-volt air pump next to the gas pump.

06:20Then we'll place another ONE of the guards.

06:30With this small 9-volt battery, it will be enough to start up our portable air conditioner,

06:48and we'll be able to cool off during the hot summer nights.

06:51We check if it works, and yes, the pump activates when we turn on the battery.

07:07Now we're going to charge our circuit with isobutane.

07:10The heart of the system is the refrigeration cycle,

07:13and although it might seem complex, it's actually based on a simple physical principle,

07:18using a gas that, when evaporating, absorbs heat from the environment.

07:23That gas is isobutane, and it's going to be our ally in turning hot air into cold air.

07:29We'll use a syringe to inject the gas into the circuit.

07:35When isobutane changes from liquid to gas, it needs energy to do so,

07:40and that energy is drawn from the heat in the surrounding air.

07:43That heat transfer is what cools the system,

07:46and to make the gas evaporate in a controlled way,

07:49we circulate it through a capillary tube,

07:52a very narrow conduit that causes a sudden pressure drop in the evaporator.

07:57As the pressure drops, the isobutane also drops in temperature and evaporates rapidly,

08:03cooling the tube through which it passes.

08:05This tube, usually made of copper due to its excellent thermal conductivity,

08:09acts as the evaporator.

08:10If we blow air through it with a fan, that air cools down instantly,

08:14but the cycle doesn't end there.

08:17Once the gas evaporates, it needs to become liquid again to repeat the process.

08:22That's where the pump comes in, simulating the role of a compressor.

08:26It collects the low-pressure gas and compresses it, increasing its temperature.

08:31Then, as it passes through another section of the circuit,

08:33the gas releases that heat into the environment and condenses.

08:37It becomes liquid again, and the circuit is complete.

08:39We now have our air conditioning unit completed and ready to start cooling the room.

08:47Let's connect our battery.

08:58As you can see, the tubes freeze quickly, reaching minus 10 degrees Celsius.

09:02And the fan will blow a stream of cold air that will help cool any room in just a few minutes.

09:20In the first measurements, we get temperatures of minus 7 degrees Celsius.

09:24But if we give it some time, we'll see the tubing get colder and colder.

09:43Until finally there it is, minus 10.

09:46No more suffering in the heat this summer just because you can't afford a commercial air conditioner.
