At a place I worked a large machine we built had a rather large vacuum tank as part of it . It had a couple port hole windows so you could see inside. When they tested it there was about a half pint of water in the bottom. I got to watch that puddle of water boil like there was a fire under it but it was 70 degrees. It was weird. The opposite effect in a pressure cooker you jack up the pressure ( without blowing it up ) to where water boils at like 300 degrees
It was the quick and easy actually. I took a Mason jar, a glue gun and a Schrader valve. Pop a hole in the lid and glue it in place. Hope it works, cheers
Question related to HVACR- what is your normal saturated condensing tempteture should be during low ambient or what tempteture it should not fall bellow, I heard 85 to 105F I want to understand low ambient head pressure control properly what is that magic number it should not fall bellow also one refrigeration tech was telling me you will want a 70 degree F liquid temp going to your TXV for better operation can you explain this a little in detailed way so I dont have ask others thank you.. Thank you.
Water actually boils in a vacuum because the loss of atmospheric pressure permits the molecules of water to literally become active and "boil and vaporize" .
I was expecting to see how to get rid of the water / moisture from the refrigeration system, i.e if you leave a pot of water on a burner for several hours, the water turns to vapor and at some point the water will evaporate completely till the pot gets completely dry, this never happens 100% to the moisture in a refrigeration system. it will help but not 100%. the boiling point of water is 100deg C, more than that it will became a vapor, vacuum do the opposite it will freeze the moisture in the system and even in the comp lub oil. in my opinion to completely remove moisture from a ref system is to change the comp lub oil, replace with a new filter drier, flushing the system with flushing agent plus nitrogen and perform a good vacuum and proper ref charge. then you need to monitor the system and do filter change every 48 hrs till the system is completely free of moisture. water can freeze in vacuum so with just a vacuum or even with a triple vacuum will not remove completely the moisture from a system .
Sir I would like you to know that you are very good in teaching..
Thank you for sharing your knowledge ❤️ god bless
Great demo! Thank you!!
Wow now I easily understand the refrigirantion system

So how did you make your jar. I want to create a container that I can place my back up camera from my truck into to clear the moister out of the lens.

Thanks!@@latentfusion2563
Pull into a deep enough vacuum and it will actually freeze
While boiling!
how long until the water is gone?
How if we vacum the fridge (the body of the fridge where we put our food), is it possible? How to do it?

Thank you.
Why don't you prove by finishing the experiment that the water will turn to vapor and be pulled out by the vacuum pump?
