You’re describing a good auto A/C. The bad kind controls the average air temperature but has no concept of radiation, resulting in the driver being way too hot when it’s a cold sunny day and the sun is coming from the front left. The thermostat thinks the average temperature is fine, runs the A/C blower on low, and fails t cool the driver.
- fishtacos 5y agoConsidering I'm describing personal experience in a rather old American automobile that I still own and drive daily, it's probable that I'm describing the bad kind. HVAC's job is not to deal with radiation and sunray angles, nor to adjust for it, IMO. To that end, it's superb engineering.
- amluto 5y agoI had a 1991 car that I consider "good". I'm not sure exactly what its secret was, possibly just generally high fan speed, but it worked fine. In my book, a good HVAC's job is that, if I set the thermostat to a temperature I find comfortable, it should make me comfortable without much further fiddling. My Tesla fails on this front. To fine tune it (which is quite necessary), I need to go through a layer of menus on the laggy touch screen and figure out which control I need to mess with to stay comfortable. This is dangerous.
