Refrigeration and Global Warming

Abstract

For the past century, the best technology we’ve had for coping with heat has been the air conditioner. Air conditioners run refrigerant through coils in a loop. The refrigerant absorbs heat from inside a room as it turns from liquid to gas, then deposits heat outside as it’s condensed into liquid again. Because cooler air holds less moisture, water vapor condenses on the conditioner’s coils, lowering the humidity.
