Looks aside, air conditioning is a win for postal workers in hot climates. The Grumman LLV doesn't have it, and postal workers are required to keep the windows shut when they leave the vehicle, even in 115°F days in Phoenix.
- hellbannedguy 6y agoI imagine they will keep a few gas powered vehicles for very hot climates.
- colineartheta 6y agoWhat? AC is unrelated to the energy source of the drivetrain.
- dorfsmay 6y agoAt the end of the day, you need enough energy onboard, and gas is much more dense. Hybrid cars turn the ICE engine on at intersection when AC or heat is on, to convert gas into electricity and avoid depleting the batteries completely.
- colineartheta 6y agoThanks for explaining energy density to me! Now explain why AC matters when the new contract is for ICE vehicles. You and the original commenter I was responding to seem to be worried about nothing.
- dorfsmay 6y agoI think OP meant that needing AC in a lot of vehicles in the US (everywhere it gets really hot) a 100% electrical fleet didn't make sense, and that this consideration might have influenced the decision to go with ICE. If you are not being sarcastic about learning about density, check out why, it was mind boggling for me!
- core-questions 6y agoI think you're thinking of Alternating Current and they're thinking of Air Conditioning.
- colineartheta 6y agoNo, I'm pretty confident I'm talking about Air Conditioning, considering that's what I was responding to.
- fomine3 6y agoBut is it serious compared to cold situation? Cooling 40C to 25C is just -15C difference, but warming -10C to 20C is 30C.
- dorfsmay 6y agoValid question, I don't know the exact answer, but keep in mind that a closed cabin with windows will heat up naturally when the sun is up. Humans generate heat which is also trapped in that cabin. Inefficiencies in transmission etc... also generate heat although I'm not sure it's enough to make a difference. Remember that the international space station is artificially cooled despite one side being exposed to 0 Kelvin.
- slimsag 6y agoI've lived in Phoenix for over a decade, where it regularly reaches 120F during the summer. Not once have I ever seen a USPS vehicle other than the Grumman LLV, which has no AC, even during the summer months and at several different residences across the state.
