Liquid cooling involves transferring heat in the air to liquid running through the system. As a closed loop system, liquid-cooled climate control can also provide dehumidification in addition to cooling. Pipes run liquid through the building and into air handlers located in the room. From there, the warm air is blown over cold pipes that absorb the heat in the air, resulting in cold air and warmer water leaving the air handler.
