Adding Air Condition To Teardrop

Postby Paul Massie » Sun Jul 24, 2016 4:59 pm

Any thoughts on air conditioning a teardrop?

I'm thinking of building a double box like this. Inner box would vent through floor with a 3" or 4" PVC fitting like used for toilet. This would provide the cooler fresh air. I would also drain condensation via this whole. Hot exhaust would blow out the back and then move to the left side (from top view) where it would also exhaust through another 3" or 4" hole through the floor.

All vent holes would have vent covers to prevent critters from finding their way in. Top and bottoms would be covered and the box would break in half 4" up so it can be lifted off to access AC if needed. I'll also have to find a way to add electrical in box for the plug.

I know its a lot of space to sacrifice, but AC is one of the main reasons I'm building a Teardrop for camping. I'm tired of the hot sweltering nights when we are out camping. I'm trying to minimize exterior holes and like the idea of venting through the floor so it won't matter if it is raining or not.

Top and bottom lid will be added to seal airflow. Vents will be opened in the bottom. One for intake and the other for exhaust.

Looks like it should work if the exhaust isn't to restricted by turning the 90 degree bend.

Ours is a modified window shaker connected with hoses.

I believe you'll be sadly disappointed in the performance of your AC with the venting choices your asking about. On the exhaust side without some kind of fan your going to have a hard time convincing the warm/hot air to flow down since heat rises. Also a single 3 or 4 inch vent isn't going to allow enough air to be moved. Look at the back of the AC and measure the exhaust area. You'll have to have that much vent space in square inches thru your floor. Any elbows pointing down ward will act as a restriction in air flow. This will impede preformance. The same goes for the condenser air vents on each side of the sheetmetal case.

Martin has it right, with not enough air flow the coils will freeze up, (I found that out the hard way). This is the write up and lessons learned, often the hard way. http://tnttt.com/viewtopic.php?f=30&t=44561

Mark in his Little Swiss Teardrop Trailer did a similar arrangement in venting and exhausting air through the bottom of the floor of his teardrop. It has worked very well. Here is a link to the air conditioner portion of his build: http://www.littleswissteardrop.com/air.html .

Having either the condenser intake, or exhaust venting underneath shouldn't be a huge issue. This can be beneficial for the intake to draw cool air in. Venting the exhaust out the bottom leads to some heating of the floor before it escapes around the sides though can still be viable option.

The bigger issue is when putting the condenser intake and exhaust vent underneath. The warm exhaust air wants the path of least resistance to rise.. which will often be the intake right next to it.
