window air conditioner and fan wiring picture needed

[Miriam C.]

I have a bathroom fan I would like to wire to the thermostat of my window shaker air conditioner. Does anyone have a picture of how to do this.

Thank you in advance for the help.

Ahhhhh, I haven't got a clue!

Unplug it first before you cut wires. That much I can tell you.

Good luck!

Why are you hooking a fan to your A/C unit?
Not enough air flow?

Seems one would need to have more data ... as in model number of the
shaker to get to the info you desire? Doubt if they will have a schematic
online but need to start with a model number ... I think?

Why are you hooking a fan to your A/C unit?

That was my thought when I read the question In a small area, like a TTT,
if both are running all that will happen is the air will travel from the a/c and
straight out the exhaust fan.
And I'm still confused

Bathroom exhaust fan will exhaust the hot air out of the bottom of the TD so I don't have to cut a gaping hole in the side.

I think most of the small air conditioners are about the same where they wire into the thermostat. The goal is to have the fan turn off and on with the air and not have it running all the time.

Does that make more sense? Here is a picture

M:

Your bathroom fan looks to be 120Volt?
If so, Why not splice into the AC power wire coming to the A/C unit in the
same cabinet and put a switch close to the fan in the bathroom area. That
way you can turn turn it on as needed separately, getting the power from the
same always hot AC circuit?

From your pictures it looks like you want to force air into the intake?
You can do it a couple of ways. You can wire it to the same wires going to the fan that is in the A/C or you can have it kick on with a contacter so it kicks on with the thermostat. If you hook it to the thermostat you will need to know what the control voltage is. The thermostat is low voltage that supplies control voltage to contactors or relays for the high voltage to be applied to the compresser and fans.
What exactly are you trying to do.

I just reread you post with the pics. If you want to exhaust the hot air you need to put a partition between the back of the unit and the sides. The sides intake cool air and the back exhaust's hot air. So you will also need a vent to let cool air in the sides of the unit.

IF you are trying to move air over the heat exchanger coils you are going to probably have to have fan running all the time AC unit is running, not only will you have to have a hot air exhaust, you will need a cool air intake so you can pull in cool air and circulate it over coils.... You are going to have several holes by time its all done...

M,

I am looking to do the same thing. I plan to wire the exhaust fan to the power switch on the AC so the fan will come on and go off with the AC but will not be cycled by the thermostat. Cool outside air will be supplied by vents on the side of the tear to the vents on the side of the AC. Exhaust out the rear of the AC will be through the floor of the tear with a little help from the bathroom fan. The bathroom fan is simply to boost the air flow through the AC as it isn't designed to operate in an enclosed space. You will have to seperate the side intake vents from the rear exhaust.

I think this is what you are attempting to do also. Hope this helps. I don't know how well it will work but I plan to give it a try. I think Woody has a system very much like this.

Venting is planned. This unit will have cool air vents coming up the side and a large one in the bottom of the shelf where the fan sits. Lots of holes in the shelving and bottom. The fan moves 50cfm and I hope it will move enough air to draw cool air up and across the coils and out the exhaust port. The exhaust will have a hose all the way to the floor. This is a small space and I have lots of cool air vents planned. I hope it is enough.

Ok so I also need to block off the sides. I need to rework this some.

Paul, I want the hot air to go up and be forced out the bottom so I don't have a couple of large holes in the side.

Thanks for the answers guys.

Miriam,


I have a 600 cfm fan that draws the air from the back of the AC and exhausts out the bottom of the trailer (got the idea from Woody a couple of years ago). I wired the fan to a switch that also provides the power to the AC. That way I couldn't run the AC without also running the fan. Most little window shakers have fans that keep running as the compressor cycles on and off, I'm not sure why you would want your exhaust fan to cycle with the compressor. What's up with that?
