I currently have a standard inboard marine
AC unit, the type that uses sea water
through the heat exchanger
and frankly it is a pain in the arse. It gets an air bubble in the water
line everytime I go out that requires bleeding the line before I get back and even worse, the cooling
plates frost up in the high tropical humidity and becomes a solid block of ice reducing its cooling
efficiency. I have to manually turn it off every couple of hours to let it defrost.
I notice that some of the long term liveaboards around me have fitted standard domestic window units on their saloon
roof with makeshift ducting through a hatch
. I dont want to go down that path because I think it looks ugly and would have to be removed everytime I go out.
So I have been looking at those low profile units they make for caravans and RV's. They are low enough not to interfere with my boom or rigging
but I have never seen anyone here in Thailand
using one to ask for their feedback.
Any comments would be appeciated, especially about robustness and corrosion
Thanks in advance
