Bedroom A/C

[camperman1]

Why in RV's with two A/C's do they put this style in the bedroom where you have to hear a roaring fan all night? The fan never shuts off when the compressor shuts off unlike the A/C in the main area of the RV.

My last 5th wheel had one up front. Froze your butt off when I used it. Don’t think it’s tied to the main RV cooling system. It’s only for up front on a 5th wheel. My current 5th wheel has the option for a second one but will not install one. My main one works just fine. Suppose in hot places like Arizona or Florida it will come in handy.

I have only one AC unit, and it is in the front, but it is ducted to my bedroom, and no matter how I adjust the vents, it constantly blows right on me. Mostly, I just close the ones in my bedroom when I am sleeping, in spite of the fact that I need cold air there.

Unfortunately, like a lot of other things, the RV manufacturers still need to work on these things.

Do you have louvered ceiling vents? I did, and endured the same thing, but I bought these ceiling vents and they blow horizontally, no cold air down my neck at night.
When I thought it out, they are sensible and practical. They direct chilled air into the warmer air next to the ceiling instead of down to the floor.

Some RV's use "Direct" A?Cs like the one in the first post some use "Ducted" it's up to the body bulder.. Direct vented A/C's are noisy

That sounds to me like an internal wiring issue. In a non ducted unit the fan should switch on and off with the compressor.

None of my motorhomes has had that type -- they all had the same type front and rear. So it's not all RVs.

I put a deflector over the bedroom vent that bkew on me, still got the cold air but it was aimed elsewhere.

As far as I know, the unit in the picture Post #1 does not have the option of cycling the fan with the compressor. Check the manual to see if that is true. The switch is usually a fan switch labelled as ON or AUTO. Auto provides a fan that will cycle based on the compressor duty.

It is possible to add the fan option switch but would require an experienced air conditioning tech. It is very possible that there were same units made with the fan switch and other options at a larger price. The controls shown in the photo are very basic.

It's not ALL RVs, but the constant fan type is a fairly common. Of the 3 coaches I had with separate bedroom a/c units, one had the constant fan & two did not.

I can give you the rationale but I won't try to defend it, since it's likely a personal preference thing. As explained to me, the constant fan helps keep the room temperature more even and avoids the annoying change in sound levels as the fan cycles on or off.

Unfortunately, my vent in the bedroom ceiling is a double one, so not sure I can put a deflector on it. Can't find a photo of it online, but it is two round vents in one unit. Each can be vented in a different direction, but I will look around for something like you suggested that might fit.

We turn off the bedroom A/C and just use the front one at night. Sometimes we supplement the airflow with a small fan sitting on the floor in the hallway helping to push cooler air into the bedroom.

In a non-ducted unit you are better with fan Full on Full time. Your mind will block some of the noise. Won't happen if it switches on and off.

Mine turns the fan off. It drives us crazy because it wakes us up every time it cycles. Our thermostat has a fan setting for High, Low, and Auto. I usually leave it in Auto. Maybe if I put it in high or low it would be quieter when the compressor starts?

 

[Henry J Fate]

Switched to Hi or Low will run the fan continuously. The Auto position can look at the temperature differential and choose Hi or Low but that might be too advanced for the thermostat you have. Typically, the Auto setting will use the Hi fan speed.

It would have no effect on compressor noise - it only changes the fan speed and autocycle vs constant fan. Low & High are both constant fan.

Does it actually get significantly louder when the compressor starts? With the air conditioners that we have had, the noise was mostly from the blower.

We do something very similar. During the day we try and keep the tv cool with the bedroom air condition. If it’s not 95 degrees it works well. Then at night we use the lower air conditioner only. Cuts down on noise.

I will say again the on/off/on/off of the fan is most annoying. turn it on and leave it on (high is best) and your mind eventually (usuallyu takes just a few minutes) filters it out. Or most of it.
Also hides the sounds from outside like the knock-down/drag-out fight next site over,.
