Too hot for me

mzodarg · 07-19-2018, 06:14 AM

A/c couldn't keep up, we planned to camp for 5 days. the A/C was respectable in relation to how hot it was, but 86 degrees in the camper was miserable. We tapped out and are packing it out this morning!

Yikes

115 degrees...…..I can't imagine that temperature.

Where were you camping at?

Can't blame you a bit, that is just too hot to be enjoyable.

Any thought, ideas on keeping the camper cooler are appreciated.86 degrees inside with an door temp of 115 is decent as far as the difference, just not comfy. I did have two large fans moving air and around 6PM it began to cool a lot better and by 8:30 I had to turn up the t-stat, it was freezing! I did a search and read quite a few suggestions. Wondering what other are doing?

I have an infrared laser thermometer and yesterday our asphalt driveway in North Texas read 158.2 degrees (F). Shoes are highly recommended.

Well, if its any consolation it is supposed to cool off a little next week lower 90's around Tulsa.

A/C's are designed for a 15 degree reduction in temperature. You, at 86 degrees are somehow gaining extra cooling.

It is currently 110 degrees in Fort Worth, as I type this. Cooling to a projected 106 tomorrow. The best heat reduction I currently gain is down to 94-95 degrees inside RV. NOT the weather to be using RV!!!

We just cancelled our trip for this week at Nararro Mills Lake. Been 105 to 110 every day.

Yes, they will reduce incoming air by about 15 deg. But he's not "gaining extra cooling." There's more to the story:

As the air temperature inside drops, the incoming air temperature into the AC also drops, and the discharge air should also drop. If this didn't work, your house would never get to 75 deg when it's 100 deg outside. What's good in your house is that it is much better insulated than your trailer. You've also got an AC unit that is capable of removing a lot more BTU's than your 13.5K or 15K BTU RV unit. (A 3 ton house AC is about 36K BTUs.)

The flow rate of heat into your rig is dependent on the temperature difference between the outside and the inside and the R-value of the insulation between them. Heat flows from high temperature to low temperature. Sunlight on the roof and walls will increase their temperature.

So when it's hot outside and hot inside, there is less flow of heat (BTUs) into the trailer. But when you start cooling the inside, the heat flow actually increases. And it will be greater at any given temperature difference than it will in your house because the R-value of insulation in the trailer is much lower than in your house. So, when the heat flow into the unit equals the heat being removed by the AC, cooling stops. So given our lousy insulation and small AC units, cooling RV's is tough.

Anything to improve insulation (Reflectix, etc) or reduce solar incidence (parking in the shade) will help the AC do a better job. If you could provide enough insulation, your AC would freeze you out, and it wouldn't be "gaining extra cooling."

We ended tapping out due to the heat. We were in 115 degree heat and the trailer was 86 degrees. Measure with an infrared temp gauge.

As stated we had two large fans blowing on high on both side of the trailer. There wasn't any trees for shade. Around 7pm that evening trailer cooled down significantly with an outdoor temp in the mid 90's. I've got 2 AC units, a 13k btu and a 15K btu.

Lesson learned for this newbie, I will be more prepared in the future for the heat and avoid camping in extreme heat.

Thanks for the link, great read and I'll definitely be doing this.

This maybe true, we had the trailer cold inside in the morning. I do know that the both units were pumping out 69 degree when I tested the ambient indoor temp with an infrared temp gauge. Agree with the statement, not the weather to be RVing.

I know that there around 10s of thousand of PPL that fulltime, what are they doing to not be miserable.

Shade makes a huge difference.

tfmdgm · 07-23-2018, 06:20 AM

Even if you can get the AC to keep the trailer cool in these 100+ temperatures, it's still too hot to do anything outside. I don't go camping to just sit inside the trailer. I like to enjoy the outdoors. Therefore, my trailer usually sits in the yard July through September.

Ditto!

Roberte52 · 07-23-2018, 06:50 AM

Our trailer and my Harley don't get used in these temperatures! Gonna be around 110' today.

Dave Lyon · 07-23-2018, 06:59 AM

Come on up to Northern Canada for some relief from the heat!
