rv type airconditioner units

[pbusanga]

Hi those with these rv roof mounted type airconditioner units... how do they hold up to the marine environment..i thought they would have corroded very quickly ???

Not sure how long mine has been on the boat because I just bought the boat in March of this year with theAC already installed, but I would imagine a couple years anyway. Holding up just fine, in fact had the AC cranked this past weekend when it was over 100 degrees out there...what a blessing that was! I do remove the inverters and take them home after each use though.

Being in the A/C business on Florida's East coast I have some experience at this. The Coleman type units will last less than five years on the beach. On a boat probably less. There is a product called Coil Guard that comes in an aerosol can for about $20 at most A/C distributors and some Lowes. You spray it through the coils when the unit is running to coat the coils. Half a can should do it, then remove the top and spray the rest on all the metal parts inside. If done when new it will triple the life of a unit. If it's a used unit, it should be done after a good coil cleaning with a caustic cleaner (Lowes) to remove all of the oxidized aluminum. I swear I'm going to get around to modifying a 5000 Btu window unit one day to water cooling for my 2520 cabin.

This one is holding up very well. Perhaps Mokee can remember how long it's been up there.

This <$100 window unit was working fine after 5 years; I upgraded from the 5000 to a 6000 when I found out my generator could easily handle the add'l BTU's.

Both these boats are trailered, spending their off hours at the house.

So the advantage of the water cooled A/C units is longevity? One of the big disadvantages of water units is they can't be used on the road while WallyDocking (staying in WalMart parking lots overnight). We used our boats as campers on the trip to Alaska and man was that A/C nice.

My hat is off to the Freon Kings. Yea, trailering you need air cooling. I had a similar rig on my '85 ChrisCraft Cuddy for family vacations. Worked great

We installed the Coleman Polar Cub in '06. This is its 5th summer of use.

is tis unit loud in the cabin?

 

[coolbreeze]

no . The loadest thing about this unit is the blower and its quite too. I think this is the best way to cool a parker.. I am not finished yet , Next it to build a box around it and sound proof it .. I can't beleiev noone has done this yet to there machine.. Beats cuttin holes in the roof and exposing it to the salt

Coleman builds a roof top A/C for boats. It is called the SeaMach, it has hoses and coated coils and internal parts. I am going to install one with A/C and Heat on my boat.

Be careful with that.

Load Amperage:
Cooling (low) ............ 14.3 Amps
Cooling (high) ........... 14.9 Amps
Heating .................. 16.1 Amps

Power Consumption:
Cooling (low) ........... 1680 Watts
Cooling (high) .......... 1875 Watts
Heating ................. 1900 Watts

Maxing out a generator can be hazardous to the generator.

This is 2000 Honda spec.

http://powerequipment.honda.com/generat ... ls/eu2000i

120V 2000W max. (16.7A) 1600W rated (13.3A)

The 1600watt @ 13.3amps is the Continues rating. Meaning that is the maxed out continuous run rating. To exceed this the life of the generator will dwindle fast.
