Abstract: 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 far gravity collection. The evaporator is cooled by a closed refrigerant circuit.

Abstract: A distiller to be used for water purification, said distiller comprising a condenser, an evaporation pan, means for allowing heated air to enter below said pan and joining an airflow above the pan, and an evaporator for collecting water from the airflow The method for purifying water using this distiller is to draw airflow above the evaporation pan containing contaminated water, passing the airflow across a cooling element, into a heat pipe, through a condenser and through the evaporation pan Purified water is collected from the airflow when it is passed across the cooling element.
