We recommend our clients leave their units running when away from the boat during the week for for small periods. That way you have cold beer
when you show up rather than not a cold fridge until Saturday morning. Do you turn your home refrigerator
off when you leave for a week? Wearing out the compressor
just isn't a real concern when you are dealing with a near 30yr life span on the compressor based on normal duty cycle times.
Now what is a concern to be aware of and things to consider.
1. If your dock
power goes out on Monday then by Friday when you show up your house bank could be sucked down and dead. So I would NOT leave my unit on unless you have enough solar
aboard to keep up with your refrigeration load. Relying on shore power
...well that is a coiled snake waiting to bite you in the A#$.
2. As if you need another reason to NOT have a pumped water cooled unit, as Richard mentioned above, if your water cooling
loop fails...you can damage your system. So with a pumped water cooled reefer system, no...it's just too risky. Turn it off, another good argument against that nightmare. Ask Skip on Flying Pig about pumped water cooling nightmare and you will understand why pumped water cooling is a disaster waiting to happen.
Some refrigeration systems have a faster/slower start-up time.
For example, a rolled thin aluminum
evaporation unit has a much faster box pull down time than say a eutectic holding plate. The aluminum
thin evaporator just needs to pull heat out of the box at start-up, where the eutectic holding plate needs to pull heat out of the box AND freeze the liquid to a solid, so that takes more time and works the compressor harder.
From a convenience standpoint, I'm an advocate of leaving the refrigerator/freezer on because you and I know that the more comfortable you can make the boating
weekend, then the more your Wife/Girlfriend or Significant other (hell even you) will want to spend the weekend on the boat. If its like camping every weekend where you are having to load and unload the refrigerator
every time....sheesh...who wants to worry about that.
