Heat pipes may be described as having two sections:
precool and reheat. The first section is located in the
incoming air stream. When warm air passes over the
heat pipes, the refrigerant vaporizes, carrying heat to
the second section of heat pipes, placed downstream.
Because some heat has been removed from the air
before encountering the evaporator coil, the incoming
air stream section is called the precool heat pipe.

Air passing through the evaporator coil is assisted to
a lower temperature, resulting in greater condensate
removal. The "overcooled" air is then reheated to a
comfortable temperature by the reheat heat pipe
section, using the heat transferred from the precool
heat pipe.

This entire process of precool and reheat is
accomplished with no additional energy use. The result
is an air conditioning system with the ability to remove
50 to 100% more moisture than regular systems.
