Hi World - I need some info:
I'm working to add A/C to my build and I found this little set up that's 10.5" wide, 8.5" deep and 4.5" tall. What I don't know is what's possible in terms of orientation of these evaporator/ fan units. I know they have to drain any condensation (and not into the motor, etc.) but assuming I address that: - Is there any appreciable impact to how the evap unit performs if it were stood on end, turned upside down, etc.? Essentially, does refrigerant care about flowing up vs down vs sideways? - Do any of the other components, like the expansion valve, care about orientation? If needed, I'm totally OK with cutting up the case, making one that suites my needs and reusing the components. Or, if there are other considerations, if I'm missing something, please let me know. Thanks in advance for any help! Chris Attached thumbnail(s) |

Hopefully something there made sense or is useful. Unfortunately, a lot of engineering or trial and error goes into fan-based heat exchanger systems. I've worked on industrial systems on and off for the past dozen years, and automotive systems make me uncomfortable because there isn't much data in the public domain for cars. You really just have to guess sometimes, especially when it comes down to modifying aftermarket parts.

You really just have to guess sometimes, especially when it comes down to modifying aftermarket parts. (IMG:style_emoticons/default/agree.gif) Not only that but you have to make assumptions on radiant heat gain. In a 914 during the summer with no insulation behind you the heat gain assumptions become large. Honestly, you are better off with an ice chest in the seat next to you and one of those directional fans blowing across the top of the ice at your body. I admire your enthusiasm, and you most likely will learn a lot. |
