Abstract:

Apparatus and method for extracting filtered potable drinking water from air through the use of a refrigeration system ( R) including a compressor ( ), evaporator ( ), fan ( ) condenser ( ), and a reservoir system ( D) may be provided as an indoor unit ( F), window or wall mounted unit ( G- J), or a portable or mobile indoor/outdoor unit ( M- L), and may be integrated with an existing air conditioning system ( K, L) and/or a conventional refrigerator ( J- L), or mounted in a vehicle ( R). The apparatus may also function as a dehumidifier, an air purifier, or a heat pump for cooling or heating air. In some embodiments the compressor, condenser, and water dispenser are remote from the housing. Collected water may be cooled by a secondary evaporator ( ) and heated by a secondary condenser ( ) or strip heater ( B). The secondary condenser and secondary evaporator may be connected with a secondary compressor ( A) to isolate the system for cooling water from that of condensing the air.
