At 05:18 in the video you can see that the copper coil is being sprayed with a cold gas medium. Note the spill on the table. Totally fake. You need a high pressure compressor, a condenser, drier, expansion valve or capillary tube and a evaporator.
You inject weldman its use for welding or joint two objects instead of free freeon gas how it works without that. The weldman is getting cool if it's compressed in circulation
Also, what are you using as the thermal expansion valve? Is it that orifice you plug the rubber hose into? Or because the small coil is lower it is acting as a collector and just evaporating off?. This makes sense as the pump appears to be low pressure just to move fluid that collects. I wonder if it would benefit from an orifice as it may suffer a performance issue as is if tipped.
Tip: it works on the princepals of a steam engine pump. The fan blows the cold air off the tubing cooling it to operate the pumping action. Freezing the can or chilling it like a blast freezer!😮😮😮😮❤
You could had just sprayed compressed air or freon on it to ice it.😮 Learn how to make freon, liquid nitrogen or liquid helium ffor a cryo freeze or ac unit! On your induction heater as a all in 1 unit!❤
