swamp cooler
Hi all, I purchased a swamp cooler and today ran it for the first time. The RV had been sitting in sun all day long with the fantastic fan on high, with the rear roof vent open. Temperature outs...

I goofed.
The fan speed was set to medium not to high. I thought it was a 3 speed. So wattage draw on Max fan with pump and louvers active is 32 watts not 20.
Time is 11 a.m. on June 24th
I have moved the cooler so that the air intake is next to the dinette window (east). That particular surface is at 36 c (96.8 f) when the ambient outdoors is only 22.3 c (72.1 f) humidity 71%
The interior of the RV is 25 c (77 f) humidity 57%
Output at the new higher fan speed is currently 24 c (75.2 f) humidity 71%. Input air is considerably hotter.
I'm leaving a West window open about 8" x 6" with the roof vents open and fantastic fan on low. I tried it first without the fan hoping for a chimney effect but it doesn't "fill the bill".
north wall 28.7 c (83.6 f)
east wall 30.1 c (86.2 f)
south wall 28.4 c (83.1 f)
west wall 28.4 c (83.1 f)
