system on my boat
has a 5 cu ft freezer
and a 7 cu ft refer compartment. It currently has both an AB Power
Plate coupled with a AB Cold Machine and a Frigoboat 160F evaporator coupled with a Frigoboat Capri
50F, installed in the freezer
. Both of these units are controlled by a single
AB digital controller. There is a spill over fan between the boxes, with a separate AB digital controller, to cool the refrigeration
The system has been working more or less OK, but I thought there was too little cycling off time. My solar panels
were keeping up most of the time (West Coast Florida), but Iíve not liked the battery
draw over night.
Today Iíve found that the ColdMachine has actually expiredÖ. I donít know itís age, but suspect well over 10 years. So my first task is to replace that unit.
My question is about sensibility of having a power
plate installed in the same box with a thin plate evaporator. Can they be expected to work
nicely together? How does a single
controller operate condenser unit driving these two different type of units?
My gut tells me to take out the power plate now that Iím taking out the ColdMachine, and install another Capri
50F with another thin plate evaporator. But I do want to be smart about what I remove.
Iíd appreciate input on how the power plate and thin plate evaporator really work
together (or not) with a single controller, fed with only a temperature input against a set point temperature.
