How to tell a pair of strangers with high emotional intelligence that the air conditioner is too low and I am so cold?

Pretend to sneeze twice and hug your arms, and most people will understand. If you are near the window, you can also roll down the window and let some hot air in. If the other person objects, you can explain that it is a little cold. Of course, you can also explain directly to each other, it's a little cold. Can you turn on the air conditioner? This is a reasonable request. Don't be embarrassed.
