Correct yea, the 90 minute timeframe was without AC.

Bbbbbbbbbbb@lemmy.world 1 day agoShe she parked at about 2, car turned off at about 3, she came back at about 4.30. She left a 1 year old and a 2 year old alone in public for 2.5 hours.

And that assumes the AC didn’t crap out earlier because it was left idling in ridiculous heat. The system is not designed to be idled that long, and the cooling systems assume the car is moving for most of the time it’s on. (Both the engine and the cabin ac here.)
Even if the car didn’t turn off automatically, it’s still dangerous and in the “extremely stupid” degrees of negligence.

Firmly agree with the statement that it was irresponsible because yes it was regardless.
However, disagree with the statement that a climate control system is not meant to be operated while idle. That is an old myth that I expect came from back when there was fewer electrical components in the car so not turning the ac /off/ before turning the vehicle off would risk damaging the cars electrical.
To a vehicle’s climate control system it doesn’t give a damn if it’s driving or idle. Now, while being idle, you have less fuel efficiency, And if you don’t have the engine running, it will drain more battery than needed, which will make your battery less efficient. But as for actual wear and tear on the components, running it at idle is almost no difference than whether you’re driving with it on.
Again, though, didn’t claim it wasn’t irresponsible either way, But it’s highly unlikely that Climate system would have failed if the vehicle had stayed on.

that’s not actually a myth. The car is functionally not designed to be left on idle for extended periods. (Note, I’m saying extended periods. Warming/cooling your car at idle is normal. idling at a stop light is normal. Five minutes while waiting to pick some one up is normal. Leaving it to stay cool for 2 hours is outside that design window.)
When an engine is idling, it’s turning at a lower RPM than when moving. of particular note here is that the alternator and AC compressor are both driven by the serpetine belt directly connected to the crankshaft. The lower RPM makes both less efficient. For the compressor, what this means is that the AC system is turning more slowly than it normally would, reducing the total amount of cooling. For the alternator; it produces less electricity and may cause the battery to be discharging. Depends on some things, including how hard the AC is having to work, etc.
Further, because the car is not moving, there is less air moving around the engine compartment (or wherever the radiator for the engine and the AC is located.) This equates to higher operating temperatures for the engine, as well as yet more reduced ability for the AC system to remove excess heat from the cabin.
just because an AC can be run at idle for extended periods doesn’t mean it’s designed to, and doing so, especially on old or poorly maintained systems, in excessive heat, is likely to cause it to crap out where it wouldn’t have normally. Is it a particularly high probability? Not really. Is it still too high considering it’s a life-safety system? fucking absolutely.

The 1yr old and 2 yr old were left alone in a car, for 90 minutes.
This was negligience long before a child died.

Also you’re supposed to wait a full year before becoming pregnant again after having a kid so your body can heal and re-normalize. Having kids that close together is hell for parenting and hell for your body

Exactly. Even if it was 68F outside, it’s still extreme negligence.
