Abstract
Apparatus for purifying liquid including a container for the liquid, means for heating the liquid when in the container to vaporize the liquid, means for cooling the vapor to form a condensate and a collector for collecting the condensate, the heating means comprising a condenser of a refrigerant circulatory systems and the cooling means comprising an evaporator of the system so that refrigerant liquified in the condenser gives off heat to heat the said liquid and evaporation of the liquid in the evaporator causes heat to be absorbed from the vapor thereby cooling the vapor to for the condensate.
