Here is picture of the new faucet, still needs final install.
The new LG model LP0711WNR - rated at 7,000 Btu for up to 200 sq. ft room.
That would be about 1,600 cubic feet of air. The trailer is only 112 sq. ft x 6.5 tall.
About 750 cubic feet of air space - less 50% for all the cabinets & stuff,
so the unit is only cooling about 350 cubic feet of air space.
Its working about 20% of its rated capacity at 40 sq. ft.
So now we need a hot 100 deg exterior day.
This is the newer R410A Freon by the way.
Cost of the unit was $250
The unit is connected to a small floor air vent
approx. 3 x 6". I did notice it makes a hell of a lot of negative
air pressure inside the trailer when running.
I may change the duct to a regular insulated house duct
rated at R-6 fiberglass - as this will be more flexible
and easier to work with. Lots of people complained about the
duct in the product review.
