As a/c refrigerant passes through an expansion tube or valve it changes liquid to gas as the instructor states . Very well done instructor explanation !
You show the heat transfer going from the engine side of the condenser and out the front of the condenser against the wind.. I thought the air flow came through the condenser coil with the assistance of the fan pulling it through. The air flow should be pulling in from the front of the truck which helps with the transfer of heat when the truck is traveling forward. Am I wrong, or was this just more detail???
Just a quick question, how is it that when the refrigerant goes through the expansion valve does it drop in temperature. What causes it to drop in temperature?

The rapid change of pressure
Yeah your right high temperature liquid drop to low temperature vapor when it pass to evaporator coil and back to compressor.
