Hi all,
Recently got a window AC for my bedroom. It’s presently using its automatic ‘eco’ mode, which seems to turn on around ~75 degrees F and off around ~72 degrees F.
This seems a touch excessive to me, as it seems to be on more than off.
I have the Thermal Comfort integration, which provides a range of different thermal indices.
Numeric indices: (dew point, frost point, absolute humidity, moist air enthalpy)
Bio indices: humidex, heat index.
Human perceived temperatures or “feels like temperatures”: dew point perception, humidex perception, relative strain perception, summer scharlau perception, summer simmer perception, thorms discomfort perception.
I have a broadlink IR blaster that I could toggle the AC on and off with.
Would automating off of one (or more) of these thermal indices be more optimal? Would there be a better way?
Here’s a graph for some context:
Light blue: Bedroom humidex
Dark blue: Outside humidex
Red: Bedroom temp
Orange: Outside temp
Thanks so much!
I’m not super familiar with humidex, I was going to suggest taking a look at how your values fit into a psychometric chart but it’d probably be more trouble than it’s worth, especially if you just have a single window unit. Your humidity is just going to dump every time the unit kicks on to drop the temp anyways
An easy thing you could automate would be to include time schedules as well as better temp ranges. Most of your cycling is from 1800-0600 (is this chart time offset? I don’t get why so much of your external heat gain is overnight). So you could avoid some of that by precooling below your set temp beforehand. I was going to suggest doing this at night, which is also when power prices are usually lower, but again it looks like it gets hotter outside at night so I’m not sure.
Regardless, before these periods of heat gain run the ac in a continuous cycle a few degrees below your comfort zone, which will also dehumidify the air more, extending your comfort zone time during heat gain without cycling
Apologies, just realized I posted from my browser that’s set to UTC time. I’ll look in to doing it based off of time/periods of heat gain, thanks!
Below is correct timezone.
