Abstract:
Apparatus for use in a building for producing potable water from moisture-laden air, comprising:a housing adapted for placement in a building and having air intake means and air exhaust means for conducting air therethrough; air filtration means for filtering air entering said housing; refrigeration means including a refrigerant evaporator and condenser disposed in said housing, a compressor operatively connected with a power source and with said condenser, and an expansion valve operatively connected between said condenser and said evaporator; said evaporator and said condenser each helically coiled, and said coiled condenser disposed generally concentrically within said coiled evaporator in a nested relation; forced-draft means operatively connected with said power source for drawing ambient air in the building into said housing through said intake means, conducting the air in heat exchanging relationship with said evaporator and said condenser, and exhausting the air from said housing; the refrigerant in a refrigerating cycle being compressed in said compressor and fed through said condenser where it is liquefied to dissipate heat into air passing through said housing then fed through said expansion valve and expanded then fed through said evaporator to abstract heat from air passing through said housing, the air being filtered by said air filtration means and cooled by said evaporator to form condensation thereon and the cooled air being exhausted through said condenser; reservoir means connected with said evaporator for collecting the condensation formed thereon; isolating means disposed between said evaporator and said reservoir means for isolating the condensation collected in said reservoir from impurities and from surrounding ambient air temperature; temperature control means for controlling the temperature of the condensation passing between said evaporator and said reservoir means to facilitate consistent temperature of the condensation collected in said reservoir means; water filtration means disposed between said evaporator and said reservoir means for removing impurities from the condensation such that the collected condensation is potable and suited for human consumption; water dispensing means connected with said reservoir means for removing the collected condensation; and monitoring and control means for monitoring and controlling the operation of said apparatus; wherein said apparatus provides potable water, and serves as an air purifier and dehumidifier.
