[C38] Refrigeration

Hi, Steve.  Take a look at the Norcold Model SCQT4407 icebox conversion
unit.  I have it and it fits well and works well.  Operates on 12V DC or 110
AC.  Switches automatically when attached to shore power.  Many sources but
Westmarine carries it for around $625.

I have searched through the last few years of posts and didnt see any
discussion on refrigeration systems so I have a few questions for those of
you with them.  I am considering the Isotherm 4201 or the Virtrifrigo both
use the danfoss BD35F compressor for a max of 8.8 cubic feet ( Our boxes are
5.6),  Both have ASU holding plate options and both use seawater for cooling
the compressor.  I am thinking of teeing off the engine raw water intake and
draining through a tee in the galley sink drain.   The nice thing about the
virtifrigo is that it has a holding plate that will fit nicely on the aft
wall of the upper ice box on the port side.  It is 11 X 2.5 x 8.  Any other
size will interfere with the main ice box area.. 

 

Questions are :  

 

1)  anyone have any recommendations or warnings on brands?

2) I'm sure there is some math for figuring out the proper size of holding
plate for cubic volume, anyone?

3) As an option what about making the cooling line a closed loop and running
the tube from the compressor pump through the bilge and back to the
compressor, that would be preferable to teeing off at through hulls If the
run is long enough to cool the water before heading back to the pump.  

 

Thanks
