venting the air condition

[norm's tear drop]

Can some one tell me what side of the unit is best to run a duct work to ?
There is a vent on both sides should i vent the side with the fan or the side with condenser
i thought i would vent the fan side but i thought i read in here were it was best to vent the condenser side so it would pull fresh air accross the the condenser to keep it cooler ? any truth to this
Any help would be appreciated

There needs to be some sort of a vent for the condenser fan to pull the air across the condenser. I saw a photo on one of the build pages.

Norm, there are 2 area that need access to venting...the sides/top of the AC sucks air in to cool the condenser and compressor and the back side which exhausts the air pulled in thru the sides...you must have air access to these places...air in and air out...you can get by with giving access to the side of the AC with the compressor and having a way to vent off the hot air coming out the back of the unit...IF the air is restricted thru these vents, the operating temps go up, the head pressure of the compressor goes up and the efficiencies of the unit goes down...ya gotta have proper venting of the unit...................

Norm,

I isolated the back of the AC behind the fresh air slots with a plywood enclosure and used a 120 cfm bathroom exhaust fan to suck the air through the back of the unit and out the bottom of the trailer.

The vent on the side has to be open to the out of doors to dissipate the heat from the compressor. You want to deal with the front, the cool air on the top, and the return on the bottom.

Nice diagram – that should help with the design of an internally mounted unit – should and an intake and an outflow vent in the design.
