More refrigeration on a 34
Thanks for your responses. I think I can keep my current system working for another year and that is probably what I will do. In the mean time I will continue to evaluate my goals and try to decide what the optimal long term solution would be.
1. A system with no 110v component that can take advantage of alternate power sources.
2. As energy efficient as possible.
3. Some capacity to keep frozen food.
1. Simplify. The 110v compressor is large and its location int the engine compartment complicates access to the steering and rudder systems. I believe a nice little 12 volt keel cooled system could be fitted under the waste basket next to the sink. This is wasted space as it is.
2. The holding plate and engine drive system works well for me and combined with a 12 volt system would provide a level of redundancy. However, a straight 12 volt system would simplify things.
3. I can currently keep some food frozen for short periods of time, but not cold enough for more that a week or two. The frig box is divided horizontally into two compartments, the bottom half serves as a freezer and the top the frig. A vertical division or freezer bin would probably give me a better freezer compartment but at the cost of less convenient access to refrigerated items.
1. Keep the holding plate and engine drive and replace the 110 with a Seafrost 12 volt. The advantage is that it is straight forward with minimal changes. The disadvantage to this is that the Seafrost unit is larger than others and doesn't have a keel cooled option so it would need to remain in the engine compartment.
2. Replace everything with a Frigoboat keel cooled system with a freezer bin.
3. Replace everything with a Isotherm holding plate system with a cooler on the sink drain. This system runs the compressor harder to freeze the holding plate when the batteries are being charged. In theory, this system makes sense to me, but I would need to do more research to see how they work in practice.
4. Other options and/or combination of the above.
At any rate, I think I can put off the decision for another year.
Thanks again for taking the time to read and comment on my ramblings.
