Filed:

Nov 27, 2002

Appl. No.:

10/305611

Inventors:

Daniel R. Engel - Cleveland OH

Assignee:

Global Water Limited - Kowloontong

International Classification:

F25D 1700

US Classification:

62177, 62150

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.

Abstract:

Apparatus and method for extracting potable drinking water from moisture-laden atmospheric air through the use of a refrigeration system. A compact housing contains a compressor, an evaporator unit, fan unit, condenser unit, and a reservoir which may contain a secondary evaporator unit and condenser unit. The fan pulls a stream of atmospheric air through a filter and through the evaporator to clean and cool the air and exhausts cooled air through the condenser. The water is collected as condensation by the evaporator and directed to the reservoir through a filter system and a water seal. The reservoir may have separate compartments for holding cool or warm water. The secondary evaporator is submersed in the cool water compartment for cooling the water collected in the reservoir and the secondary condenser is submersed in the warm water compartment for heating the collected water. Operation of the system is controlled by a control module which may also contain a microprocessor for assuring maximum condensation and a removable I. C. program module to alter the operation for specific conditions.
