How to measure the degree of "cold" in a car's air conditioning, let the numbers tell



A comfortable air conditioned environment for us is between 20 to 29 degrees C & a humidity range of 30% to 70%.  For example, for the car’s cabin temperature to reach 20 C the corresponding humidity should be at 30%.  To efficiently achieve this level of coldness, the temperature measured just on the surface of the evaporator or cooling coil would be about 2 C.

A quick way to access your car’s ac performance is to wind down both the driver’s & passenger’s side window & set the ac to the coldest mark.  You would then measure the temperature in the ac vent.  A minimum performance standard, the ac vent temperature would be about 8 C or lower, the lower the better.  We have a video to demonstrate this performance measurement.

Keep cool & stay heathy & welcome the hot season!

Thank you for reading my blog.
