Roof vs Cruise air

[merle&louise]

Tom,

Thanks for the reply; it is amazing how hot that asphalt can get.

Jim,

Glad to see that Liberty fixed that little problem. Cleaning AC filters is very important to proper cooling. My 93 Newell AC filter for the middle AC was also difficult to get to. You could remove it easily, but putting it back took a little finess.

Jon,

I would submit that yes if I had a Liberty, just the casino chic, whorehouse interior would reject heat such that little or no supplemental cooling would be required. However, since I do football tied up to 50 amp shore power now, the CA heat was fairly difficult neat the front of the coach (near where the awning shade is). With the new awnings - two big ones on the curb side and the roof air, I'm thinking I'll be a little happier.

But my Cruisairs would get the bus well-digger's ass cold, so they were dialed in. If you were sitting still. Had my first run in high temp in the new bus this past weekend. Dash AC and two AC's running off inverter kept it cool, but starting the generator prior to arrival and firing up all four was the ticket.

I'd like to convince everyone with CA units in some other conversion the simple fix would be to jack up the CAs and slide a Liberty under them but there is more to the issue than that.

I don't think there is a single simple answer although Greg's addition of a second fan to supplement the squirrel cage fan sould like the simplest answer. I still suspect a great deal of the problem (apart from trying to cool a condenser with air heated to very high temperatures radiating from a highway) is the failure of the intake air and the exhaust air from the condensers to be separated. A baffle or some type of separator is required if there is any possibility of drawing hot exhausted air back into the condensing unit. I have a center baffle that absolutely stops that type of circular flow.

If that baffle was missing when I bought my bus I would have never known of it. How do you know it is missing if you have nothing to compare it to? It did not take long to recognize how critical that simple barrier is to successful CA operation. I don't think the designers of the CA or our converters are stupid. I do think the locations are a compromise, but when properly charged, and all baffles are in place the CAs work quite well under all but extreme circumstances such as when driving down the highway in the desert Southwest at 3:00 PM when the ambient temps are in excess of 105, and the blacktop has reached temperatures high enough to frie eggs.

John I will get out my IR gun when I get back home. Currently in Germany for three weeks.

Yup, Jon, that's why the OTR for 3 PM runs. Here's the $1,000,000 ?: Will 4 roof airs properly cool a stationary bus in the sun @120?

[Sid Tuls]

No it will be comfortable but you wont be cold. We spend 2 weeks a year in Parker,Az and I have 4 roof airs. The only time I'am cold is after boating with the grandkids and get burnt to you know what!!---then get into the bus for some peace and quite and then I get chilled. Thought you would like to know.

[joelselman]

Thanks Sid. I kinda figured that. If I ever redo the ceiling, I'll probably change to roof air.

[Jon Wehrenberg]

I may be wrong on this, but I don't think so. Removing or replacing the ceiling on a Liberty will probably entail a little more effort than raising and restoring the Titanic.

We ran 2 airs off the inverters and the dash air in Texas...perfect on the road. While at the lake ran 3 airs all day long and 2 at night. I was very satisfied with the....chill. One of the muggy days the drains looked like I had 3 garden hoses running under the bus.

I don't think so either.
