I have a 64 16SC. I am in the process of installing a 8000 btu window AC in the kitchen. It is in the line of cabinets on the street side. I guess it is where the old refrigerator would be. I currently have a small dorm size refer there. So if my pics show up you can see it it goes from bottom to top - dorm refer - Window AC - countertop- cooktop. I plan on creating a seal so that the AC pulls air from the cabin and then after the sealed area it expels it out the exhaust which vents through the old refrigerator vent on the street side.
Kevin, I think I follow what your are saying. Think of your a/c as if it were mounted in a window. The front of the a/c pulls air in to move over the evaporator to cool the air and blow it back out. That way it recirculates the cool air to make it colder. The hot air that is blown out the back is pulled in through the sides and top of the a/c to help cool the condenser that is on the outside of the window. If you pull air from the cabin to blow out the the exhaust your are loosing your cooling inside. You have to separate these. Look at some on the post on installing a/c under bench or cargo door. You have to create air flow from outside to flow over condenser and blow back out and these two have to be separated. I helped a friend install an a/c in the bottom of the closet just above the the wheel well in his camper. The front was completely sealed for the cool air. We put 2 small vents in the floor under the closet to pull air in the sides of the a/c then boxed in the exhaust to blow out a vent we mounted in the outside wall. Make sure the outside vent is big enough to handle the air flow coming out. Brent
I agree with blu26ovl completely. You have to intake air from outside to cool the compressor. It may seem like it is working the way you have it but you will soon overheat your compressor. My blog shows how I installed a 5000btu in my 16SC. I have an intake hidden under a wing and the exhaust is about 16 inches away. 90+ heat here in South Florida lately and it works fine so far. Been in the test stage since March and no problems.
Thanks for the info. I am going to duct my exhaust to the outside. As for the intake, the best I can come up with is a mixture of out side air via a 3" hole in the floor, and the dead space of the cabinet that the AC sits in. We will see how it works. I bought the 8k btu unit knowing that my setup was not going to be at its optimum. I bet at the end I will be running like a 5k unit.
Tell me something new. Did you guys run a drain pan? From my research it looks like the new units don't drain water. They throw the water on the coils to keep them cool. With this in mind I may drill a drain hole and pipe the built in pan to the outside with a valve on it. That way I can drain it before traveling. other wise there does not seem to be a need for a pan with a drain. What has everyone else been doing.
I placed a small pan under the drain hole in the bottom of the unit. I installed a small fitting into it and ran flexible 1/2" piping down through the closet and out the bottom. Lots of water comes out when the humidity is high.
The one we put in was not a new unit and had a drain hole. We made a metal pan to go under the a/c and ran a tube down through the floor to drain. The a/c I put in my compact slides out. It did not have a drain hole but the manual said to be sure to lean unit back to drain. I drilled a small hole in the lowest area for it to drain. Maybe I wasn't suppose to? I could always put a screw in the hole and then drain it before I leave the camp site.
