T&T: AC question

[JHWardJr at aol.com]

Arild - I TOTALLY agree on the genset issue.  Part power usage is so  bad 
for a constant rpm design (eventually someone will market a diesel-fueled  
DC/inverter type that varies power/rpm with the load.  I was not  considering 
the A/C usage away from land power.  But now that we are, why  not run the 
thing (a/c) wide open with the genset, cool the thermal mass down as  much as 
possible, then shut down the genset and the a/c.  That's what I  do.  I 
never considered running the a/c and genset all night.  Goes  against the grain 
for me.  I just blow a 12vdc fan and perspire.  I  know, ugh.
 
I will tell you I assessed insulation issues - big job on my old Taiwan  
ACMY.  Seems it needs to be built in.  I did seal the windows with  shrink 
plastic (works GREAT! - poor man's double pane) and have sun covers with  
insulating panels in the other areas.  
 
I still think bigger A/Cs are better if the power delivery system can  
handle it.  In my 42 footer, I have 32,000 BTUs in two units, can run  them wide 
open nonstop, and DO NOT get that cold if it's more than 90 outside  (NC 
humidity).  They work fine - confirmed by two local experts.   Nature of the 
old beast.

So if  you go big on
the A/c  sizes  and then decide to only run one  little unit for sleeping;
you are running the big genset under light load  conditions.  Not good for
genset  life.
