This ain't no installation tech feature (though we may get to that in the near future), but it's more an overview of air conditioning systems, how they work, why they sometimes don't work, and how to ...

Air conditioning is the science of heat transfer and the chemistry of refrigerants. To beat the summer heat, we turn to air conditioning. But that sweet, cool relief isn’t magic: it’s the science of ...

In principle, air conditioners and refrigeration units don't produce cold air. These systems transfer heat from one place to another and therefore reduce temperature in a confined area (passenger ...
