When cooling the car, a heat pump is essentially identical to a regular air conditioner of the same size. I think you'll be fine, but I'd suggest you don't get a black car if you need to park in the sun.
Don't worry, enjoy it because it will make you too cold.I'm concerned if the heat pump will keep the car cool when the Arizona temperature is at 110 degrees. I live in Arizona. My understanding is the heat pump doesn't work well at really low or high temperatures. Anyone with experience with heat pumps?
All an air conditioner, and any refrigeration system, does is take energy like heat and move it to another location...usually outside the cabin or outside a refrigerator. Air conditioners don't make cold, they remove heat from one location and move it elsewhere. Condenser is outside the cabin/refrigerator cabinet and the evaporator is inside the cabin or refrigerator. Heat moves from evaporator to the condenser.
Heat pumps are more advanced...they also move energy/heat from one location to another but they can be equipped with multiple evaporators and condensers...one of each inside the cabin, and another pair outside. In some systems with appropriate valving an evaporator or condenser (just a heat exchanger) can do both jobs but lets keep this simple. So if a heat pump moves energy/heat from the cabin to outside then it is cooling. If moving heat from outside the car to the cabin it is heating. So think of a heat pump like your heart moving blood from one organ to another. That is how Tesla uses it according to their patent. So in the winter where does the heat pump get energy when it is 0 degrees outside? Well, it can get some from outside but the heat pump can also get heat from the motors, and the battery. All of the energy systems are interconnected and the octovalve in conjunction with the heat pump directs energy/heat where it is needed. The heat pump can also heat the motors and the battery. To get rid of excess heat/energy there is a radiator in the front of the model with electronic louvers that can open and close to regulate efficiency and aerodynamics. This is really a very advanced temperature control system!
The reason you don’t see heat pumps in ICE is because you’d have to run the crank backwards
The patent describes a small resistive heater it’s probably there if needed. However, the patent also describes operating the motors in a special mode to also produce additional heat...basically a less efficient mode that produces some waste heat...just like an ICE vehicle.
I agree with you. I'm still concerned about how warm it blows on fridged days. My home heat pump has a massive resistive heater when it gets too cold. If the MY still had the ~7kw resistive heater as backup, I'd have no concern. It'd be great if a MY owner that still has a real cold morning to experiment would report on duct temperatures. Even a subjective "it blows toasty warm in less than five minutes" would be reassuring.
