Heatpump is the biggest upgrade in Gen 2, imo

[sirna7]

This is entirely correct.




Why do your posts read like an output from ChatGPT? The other users are also correct. Air Conditions and Heat Pumps work by the exact same principles when cooling. On a hot day when you are cooling things, the heat pump is operating no differently than an air conditioner would. Just because heat pumps are “generally more efficient” doesn’t mean anything. We don’t know the specific specs of this heat pump vs the air conditioner Rivian was using before.

Ignorance is bliss ?

A heat pump isn’t gonna do anything for you on hot days…

Also owning a Scandinavian Belgian built EV with a heat pump (C40) it’s not the range panacea everyone claims them to be in moderate cold. Yeah, they are more efficient than an electric resistance heater, but not a magic silver bullet to alleviate winter range reduction

*yes yes, it’ll still cool the car but it’s not magically more efficient than AC at cooling.

Im with you on this, in the real world use of EVs I don’t think it is as impactful as one would think.

I have a 2021 Polestar 2 and my wife had a 2022 C40 before her R1S and I was totally freaked out to find that the C40 had a heat pump when my P2 didn’t when practically everything else was constructed the same comparatively. We spent the good part of two and a half years driving 150+ miles a day each separately from the mountains of Colorado to Denver in all weather conditions and yes there were some differences in efficiency that could be seen with the C40 but very marginally and we both accomplished our commutes virtually in the same fashion and with the same challenges.

I once had to return to our loft/office for the night in Denver on a sub zero evening as the Electrify America chargers we would sometimes use located at the foothills to get us up the hill home, (if we had depleted our battery), did not work that evening for my Polestar and I completely blamed it on not having a heat pump or the ability to precondition the battery yet later I found out from Out of Spec Reviews that it actually was the chargers that malfunctioned that night as Kyle from their channel showed up to test those exact chargers that night and posted a video on it. So that put the verdict back out in the actual use case of heat pumps and their real world effect on the performance of EV commuting.

I bring this up as it was a consideration when leaving the C40 for the R1S knowing it wasn’t equipped with a heat pump.

Air conditioners also transfer heat from inside to outside by the exact same process as a heat pump. If an air conditioner did not transfer heat from the cabin to the outside then what do you understand to be cooling the cabin?

Regarding efficiency, if both systems use the same compressor, refrigerant, insulation, and heat exchangers (a.k.a. radiators or coils) then my understanding is any difference in cooling efficiency is too small to make a difference either way. So if a heat pump is trying to cool the inside by pumping heat to the outside there is no significant efficiency gain compared to an AC system doing the same thing with the same components.

I think you're arguing with a bot that doesn't actually understand how a heat pump works.

For some reason they are arguing a heat pump is better at cabin cooling because it can also heat the cabin.

Agree with this based on engineering experience and personal experience with heat pumps in another car. Helpful but not magic.

There are some wacky posts on this thread about how heat pumps cool the cabin vs air conditioners. The reality is, they are the same in cooling mode.

I atleast am not saying that at all. Maybe I need to read stuff up again but in my mind, an air conditioner cools but letting compressed air rapidly expand - similar to how a can of compressed air chills; similar to a refrigerator. of course the AC still “pumps” the air out from the room/car but it’s mainly for circulation. This is compared to a heat pump that moves hotter air out, over a mechanism to exchange the heat, cooling it down and finally circulating it back in.

just how I understand it until this point.

Keep those posts coming, bots and humans alike. Me is happy

Like others have echoed, no innate cooling advantage from a heat pump, unless the compressor itself is more efficient than the older unit. The main advantage is the ability to run in reverse and provide efficient transfer of heat vs inefficient resistive heating.

Let's be mature and avoid throwing accusations of botting. I thought Rivian members were better than this.

Here's the real deal: While heat pumps and traditional air conditioners operate on similar principles for cooling, heat pumps offer significant advantages. They're typically optimized with more efficient compressors and advanced refrigerant management.

Heat pumps also integrate with a vehicle's thermal systems, using waste heat from the battery and drivetrain to enhance overall efficiency—something traditional AC systems can't do. This leads to better energy use and extended range in EVs.

Plus, the refreshed Rivian R1S includes both a heat pump and an AC compressor, ensuring it can handle heating and cooling efficiently.

Nah, not you, the other guy.

Vehicles with heat pumps have likely had more engineering done with regard to overall HVAC efficiency, and that's where the big difference lies. Being more efficient to redistribute the heat that's already in the system can make a big impact.

Oh great, another heat pump debate....


"It's great!"

"It's not a great as you think, you idiot."

"Here's 11 google articles about how good/bad it is."

"Depends where you live."

"My <other_car> did/did not have it, and as a result, my spouse cheated on me."

Also, Christ will have a heat pump in his Second Coming.

That verse actually said "heart pump" in the original Greek translation. Much like early monks mistranslated "celebrate" to "celebate" on accident.

110% True. Nothing like late-night drama between the FOMOs and non-FOMOs getting heated over pumps. Just wait till someone blames their broken marriage on the lack of a heat pump! ?

Speaking of which, where did all the FOMOs go? Sounds like they couldn't handle the heat (pump debate) and bailed! ?
