cooling the sleeper

The other solution is the EPU, a battery powered Air conditioning unit combined with a diesel fired bunk heater. No noise, no vibrations, no fumes.

 

My 2020 company truck freightliner has their electric APU EAPU. It ok setup. The truck has 8 batteries to run a/c 8 hours usually. Then the trucks computers monitor the batteries voltage at 12.1 volts the truck will start automatically and high idle engine at 900RPM for 2 hours to recharge the batteries.. It's good for sleeping at night. During a 34 hour reset or if sitting the weekend it's ok system. The electric a/c is really just to cool sleeper. It only blow cold air out the sleeper vents. The truck computer as another mode call Interior Comfort Mode. That will start the engine lots more per hour and use the regular a/c to cool the front of cab in the summer heat but it not a perfect solution because the temperature sensor it's using is the one in the sleeper. So they can get hot with sun shining in front of cab and be cool in sleeper.

 

Work at a company where the trucks have Auxillary Power Units (APUs) on the truck. It's a small diesel generator/air conditioner that provides electricity and HVAC when the truck is stopped. Many of us will not work at a company unless they have APUs.

 

All of my APUs (Thermoking Tri-pac) run continuously.

 

I've never had an APU that did that and I'm a light sleeper. It is NOT that they were not doing it and I never noticed.

 

The "comfortable" temp range is determined by the person inside the truck, not some professional liar that goes home at 5 pm, has weekends off, and always showers at home.

 

It depends on where you run wildman82.
In the summer heat there are plateaus where you can sleep in relative comfort without the engine or auxiliary AC on. The Pilot/Road Ranger in St. Robert Missouri comes to mind.

You can also put a bag of ice in a bucket and sleep next to it.

In the cold weather, park facing the east and the sun shining on your windshield will warm things up in the morning.

 

i can sleep just fine with their idling. The smell of the regen gets to me or when they got it running dirty and pointed right at you. Oh and don’t get started with truck constantly purging.

and to op if your company doesn’t want you idling they better be supplying an apu. No apu I’m idling. Diesel apu? I’ll almost never idle. Electric apu? There might be some once those batteries start getting weak.

 

I agree with this wholeheartedly. There’s days when it’s 60° out but super humid and I feel like I’m choking on the thick air, I’ll run the AC even though it’s temperature wise cool. There’s days when it’s 75° and I don’t need to run the AC. It all just depends. I would never work for one of those companies that set idling criteria based on temperature. Unless they gave me an APU.

 

The APU shutting on and off doesn’t bother me in the slightest. It runs constant anyways when the outside air temp is warm. You can always leave your parking lights on. That will put enough of a demand on the APU to never shut off.

Good luck idling in any DEF equipped truck. You’re gonna gunk the DPF system up beyond recognition opening the door for constant regenerations, check engine lights, and derates. An idling motor doesn’t run hot or hard enough to burn off all of that stuff blown through at higher temps and normal operation loads.
