??? about keeping refrigerators cold
I have a large refrigerator and don't want to get rid of it since I'm
on the boat a lot, and the majority of the time at the dock. But do like to go out for a couple of days each week, and the biggest issue is the frig getting too warm unless the generator runs more than I like it to. Do they make good cold packs of some kind that can be frozen and re-frozen, and would help keep it colder without so much use of the generator? |

I use six cold packs in my reefer.

I have the same situation & I use an inverter that keeps the fridge cold for
hours - then I run the generator to charge the batteries. Works great for me. wrote in message ...

But do like to go out for a couple of days each week, and the biggest issue is the frig getting too warm unless the generator runs more than I like it to. My suggestion would be to get an inverter and battery bank that would run it while you were away from the dock. I assume that by "large" you mean a standard household, frost free unit. These things can be real pigs on energy use, as most use as much energy heating things (and I don't mean the byproduct of cooling) as they do on the compressor. A typical frost free refrigerator has 1) a heater around the door sill (open the door, put you hand against the spot the rubber gasket would rest: it's warm, isn't it?) 2) A heater on the cooling coils, which is energized on a periodic basis to melt the ice that forms Many refrigerators also have a heater under the drip tray to evaporate the water that collects from the defrost cycle! A non-frost free refrigerator would require about 100 amp-hours a day to keep things cold. A regular frost free unit would probably require twice that. If you installed an inverter and a 200 amp-hour battery (two golf cart batteries in series) and then ran your generator for a few hours each day you could probably get by for two or three days. Rod |

??? about keeping refrigerators cold
I have to go along with the inverter and a decent house battery bank. I
have an 8 cu ft household refrig on boart and run it off the inverter whenever under power, and can run it about 12 hours (in several 3 hour stretches) over 2 days. Once packed with food, they keep pretty cold by themselves - I still have ice in the trays after overnight without power. A bit of judicious power management makes everything work well.

The down side is that if you have a modified sinewave inverter (the
typical cheap ones), the compressor may run hot and its lifetime shortened by many years. A true sinewave inverter does much better but then again costs alot more. It's a tradeoff as usual.
