Patent ID: 11021855

Abstract:
Method for collecting water vapor from air as liquid water. The method includes a refrigerant compressor circulating refrigerant through a controlled dimensioned condenser into a tubing loop. A portion of the tubing loop functions as a condenser. This tube conveys the pressurized refrigerant through an expansion valve. The refrigerant pressure and temperature decreases. Ambient water vapor collects on the exterior surface of the cooled section of tube now functioning as an evaporator. The water drops from the tube surface into a reservoir for use. The tube loop extends through a multiport control valve. The method includes a control valve that cyclically and sequentially directs the refrigerant pumped from the compressor into alternate ends of the tubing loop. The cycles continually repeat. The cycles can be controlled by fluid temperature. The device can include a power supply and microprocessor controlling the generator and valves. The device may utilize a switch that detects water or ice deposits on the tube. The device can comprise a moveable frame supporting all above components.
