| azonenberg | o_O the project made hackaday | 18:31 |
|---|---|---|
| berndj | a billion hits on your blog? | 19:01 |
| azonenberg | berndj: the link was to the googlecode page actually | 19:40 |
| azonenberg | not sure if i can see stats on it | 19:40 |
| Sync | berndj: I want to try the original linde cycle first before I do some other concepts | 19:49 |
| Sync | but even commercial LN2 generators usually use 3 compressors | 19:50 |
| Sync | one to get the nitrogen up to around 25bar, one for the autocascading cooling system and one to subcool the autocascade | 19:50 |
| berndj | Sync: just staged in order to get high enough pressure to make up for losses along the way? | 19:50 |
| berndj | oh, separate systems then? | 19:51 |
| Sync | yes | 19:51 |
| berndj | i need to hint to my gyro gearloose pal that this is a worthwhile project | 19:52 |
| Sync | I'll just build a two stage cascading cooling system that will prechill the nitrogen to around -100°C and then pump the n2 through with around 100bar | 19:52 |
| Sync | ? | 19:52 |
| Sync | :D | 19:52 |
| Sync | when you use an autocascading system everything is easy besides tuning the system properly | 19:53 |
| Sync | also getting the gasses is tricky | 19:54 |
| berndj | getting? you mean not out of the air? | 21:03 |
| Sync | yes buying them | 21:09 |
| Sync | not the nitrogen, that is pretty easy but the gasses you need in the pre-cooling cycle | 21:10 |
| berndj | you mean i can't just hook up a bicycle pump to a heat exchanger and a throttle :( | 21:42 |
| Sync | no | 21:44 |
