couldn't you buy a 2 stage lab freezer ie. Cold trap with r1150 in it and extract the gas? last saturday I went to a refrigeration scrapyard to look around for interesting stuff and the guy told me...

Yeah like that. Extract the surplus to keep the pressure low in the system. store it in the high pressure vessel and block it off with stop valves or solenoid valves.
Like when you pump down a...
In the transcritical co2 systems the company I work at manufactures the compressor is started when the pressure in the receiver has risen. Although it is possible to make a system or a vessel that...
The shipping quotes are insane, so pick-up is required. for a mere 8150 dollars this awesome compressor can be yours.
Think about the amount of ice you could make :cool:
I am also not able to access my and others pages. Figured it would be due to my low post count. If that's not the case +1 on the problem.
There is allot to be read.
Some links on scientific research

Yeah cascaded auto-cascade :up: R290 is favorable for the high stage because of the low price.
I haven't crunched any numbers in excel yet. Still reading up on some research papers about...
Yeah a Bitzer S4T-5.2, Displacement 1450 RPM 50Hz 12.60 m?/h
I'm thinking about dividing the high stage(s) from the low stage(s).
This concept is usually done in big industrial refrigeration plants. Like in ammonia 2 stage systems with a booster compressor...
Hey Fugger
Nice cabinet. The Polycold gases would be difficult for me to acquire here in the Netherlands. Though every "standard"refrigerant would be no problem.
Some weeks ago I got a small...
I have being thinking a long time about making an auto-cascade and have being collecting materials which were thrown away at my workplace. The goal is to hit much lower than -100. I do not expect...
Hello,
I work for a (global) refrigeration company in the Netherlands. we engineer, produce and commision cooling and freezing installations. I do not assemble these machines, only mechanical...
