Hi Richard and others, did a second test with the lazarette open to keep it cooler. The thermometer was placed at the same level as the lower plate thus the lower temperatures. The box continued to drop to 38 F after the compressor was off when I checked half an hour afterward.
The new spread sheet is attached
Thoughts?

thanks
Richard

The condenser and compressor are in the lazarette near the generator and engine. I worked in there during the entire running test changing oils etc so maybe I didn't give it fair test. Richard, do you want me to run for two hours again? The thermometer was above and about 3" away from the top cold plate, where should I place it if I run it again?
Also do you do "house calls"?

Hi Richard, wow thank you for all the info! A few years ago (Aug 11) the system developed a leak which was fixed and the tech said it would be better for me to switch to R134A, thus the change. The two cold plates have two lines as it was an engine driven system as well as a 110 VAC compressor. The original owner could never get the engine driven part to work properly and he had tried everything, so I just took out the compressor. There is a switch to put it in manual mode? which I use now but I can also put it in auto mode and there is a RANCO control that may be the thermostat that you mentioned? I will send you a picture of it. I can run the tests with the control on auto but I don't have any sort of thermometer with me and we are still in the Bahamas. Do you want me to do the rest of the tests?

thanks
Richard

Hi Richard, here in the Bahamas I run it for 40 minutes twice a day. This gets a thin layer of frost on the plates. I am only using this as a fridge (one side colder than the other due to the spillover). I have a separate stand alone Engel that I use as a freezer. If I decided not to use the Engel then I think that an hour of run time twice a day would work as a fridge/freezer combo. Our cruising would be here for the next while. I have a bunch of pictures but I can't even put one on as it is over 192 KB, any ideas?
thanks

Richard

Probably a stupid question but here goes. I have a dual holding plate spillover system that is run by a 115 V/AC Tecumseh AE2415A compressor (1525 BTU, 1/3 HP) All the other stuff (dryer, gauges etc) are mounted on the compressor chassis. For various reasons I want to switch to a 12 volt system. Without tearing the fridge apart for the holding plates (not sure even how it was done) I would like to change the compressor to a 12 volt one but still use all the old stuff.
Can this be done?
If so any suggestions?

Thanks
Richard
