How to make a Fast Cooling Freezing AC | How does work AC | Diy Air Conditioner

I was just about to say this is bulls*i* until the end!😂

When I taught refrigeration, I placed a small compressor (salvaged from a window AC unit) on my desk. I took a roll of 3/8" copper tubing and brazed one end in the compressor discharge port. I unrolled the copper and made a big circle around all the student's work tables and brought the other end back to the compressor suction inlet. I evacuated the air and put several ounces of R22 in the loop. Just a compressor and a big circle of copper. I started the compressor and had all my students feel the copper tubing as the compressor ran. They all agreed, nothing was happening. The refrigerant may have been circulating, but there was no change in temperature any where. Then I had a volunteer student take a hammer, and standing on the other side of the copper circle, begin slowly, gently, hammering the copper tubing closed. As he tapped the copper closed, I had all the students feel the copper on both sides of the copper being hammered. Nothing happened at first. Then, suddenly, the restriction was just right and ice began to form on one side of the crushed copper, while the other side got warmer. We had built a very basic refrigeration circuit. I explained to them that we can add lots of bells and whistles to improve effectiveness and efficiency, but this is the basic circuit. They watched in awe, then I told the hammer volunteer to smash the copper closed. As he did, the refrigeration stopped. I told my students, you've now just witnessed a blocked restrictor, so you'll know it when you see it again. Simple but effective lesson.

What matters: the pressure difference. 1- Use a single engine. 2- Make the connection pipe thinner. Ex: use the needle. This will cause the pressure difference to increase. The second thing that will cause this is: The pressure that the engine can apply. You can achieve this by purchasing a higher power engine. Result: Gas is trapped on one side. It gives out energy. On the other side, the gas expands. It receives energy from outside. In your example: With 2 engines, you almost equalized the gas pressure on both sides. Order: 1- Engine Output. 2- wide pipe. (part that will release heat - Heated part - High pressure area) 3- thin pipe. (transition that will create a pressure difference) 4- wide pipe. (Part that receives heat from outside - Cooling part - Low pressure area) 5 - Engine inlet.

History....Ammonia and Butane are some of the earliest refrigerants. Ammonia back to the late 1800's. Linde and Rudolf Diesel were some of the early pioneers.

Before filling butane gas into the system, try vacuuming the system with the air compressor you use and removing all the oxygen from it and filling it with butane. Make sure you install the air compressor in the right direction. The air outlet should go to the capillary tube.

The principal is correct although a second pump between the expansion valve and the evaporator is abnormal, a pump there would be still pumping liquid coming out of the condenser. The faults are the pump not being able to generate enough pressure, the hoses not being able to take the pressure and not evacuating the air/moisture out first along with proper sealing ports for evacuation and charging refrigerant. Then there is the proper capillary expansion valve sizing and getting the quantity of refrigerant right. ~40L/175H PSI ??? [Obviously the pump would have to be able to pump up to 300PSI with sufficient volume.] Yes condensable flammable gas can be used as a refrigerant and propane has been used as a substitute for R-12. [Mexico that I know of]

Чтобы получить холод, надо сначала получить тепло, поэтому холодильники выделяют тепла больше, чем холода. И еще мне понравилось, как автор вшивым паяльником паял массивные медные трубки.

Доктору Дью на проверку😂

Allways knew Jack Daniel’s was pretty cool 😎

Not to mention that perfect vacuum is what count on efficiency

لقد لاحظة ان جميع المقاطع لهذه الفكرة يخطؤون نفس الخطأ وهو عند حقن الغاز يجب تفريغ الهواء المتواجد في الانابيب حتى يستحوذ الغاز على اغلب الفراغ في المواصير. وايضا ستكون الفائده اكبر بكثير

i like the way that water droplets form on the copper pipes and then turn to frost. And also how the frost is only forming on the pipes at the front of the bottle, but not all the way around. Its like a regular can of compressed gasses was sprayed only on the front part to form frost and then thawed, and then the video was played in reverse

Que invento mas estupendo, gracias por compartir tu proyecto

من یک مهندس مکانیک با گرایش حرارت وبرودت هستم.این سیکل به درستی طراحی شده وفقط تنها مشکلش شاید انتخاب کمپرسور باشد که در طولانی مدت به معیوب شود.درکل از زحمات شما جهت ساخت ویدئو تشکر میکنم❤❤❤

Если бы всё так бы было просто -то китайцы завалили бы всех своими дешёвыми😂 кондерами-холодильниками

I mean, you could make a decent cooling system for cheap ... but using pumps never made sense. The compressor is the only part you cant really avoid on closed loop phase change system. Home made radiators and evaporators, work. Heat transfer to the bottle can be improved a lot by using a thin plastic bag, in a bucket full of alcohol. With the evaporator coil dipped in the alcohol. As for refrigerant, if you filter it correctly lighter fluid (butane) will work fine for close to 0C temperatures.

Kde koupim napln dekuji za odkaz.

6:27 what if you took some of that tubing embraised in a lighter's fill valve instead of using a needle

The circulation air must inside condition, in closing rooms area to needs more cold

You did a good job! Keep going until you'll be a millionaire one day!!!
