Abstract
A water distillation system and process capable of high efficiency operation used in combination with a heat pump system wherein the water distillation apparatus includes a water pre-heating device positioned within the feed water to heat the feed water to approximately 150 degrees Fahrenheit to facilitate operation of a water evaporator device which vaporizes the water by boiling thereof. Contaminants are removed from this pure water vapor which is at approximately 215 degrees Fahrenheit. The water vapor is passed to a water condenser to provide high purity water at approximately 180 degrees Fahrenheit. The heat pump system provides for refrigerant condensing at approximately 225 degrees Fahrenheit to facilitate boiling of the water in the adjacent water evaporator and includes refrigerant vaporization adjacent the water condenser to facilitate absorbing and reclaiming of the latent heat of the distillate.
