A water condenser includes a fan which draws a primary airflow through an
upstream refrigerant evaporator, through an air-to-air heat exchanger and
in one embodiment also an air-to-water heat exchanger uses cold water
collected as condensate from the evaporator, the airflow to the
evaporator being pre-cooled by passing through the air-to-air heat
exchanger and the air-to-water heat exchanger prior to entry into the
evaporator wherein the airflow is further cooled to below its dew point
so as to condense moisture onto the evaporator for gravity collection.
The evaporator is cooled by a closed refrigerant circuit. The refrigerant
condenser for the closed refrigerant circuit may employ the fan drawing
the airflow through the evaporator or a separate fan, both of which
drawing an auxiliary airflow separate from the airflow through the
evaporator through a manifold whereby both the auxiliary airflow and the
airflow through the evaporator, or just the auxiliary airflow are guided
through the condenser and corresponding fan.
