An apparatus and method for condensing water vapor in air to extract liquid water includes an air duct, an air movement device, and a refrigeration system. The air duct has an entry port, an intermediate port, and an exit port; while the refrigeration system includes at least one evaporator and condenser within the air duct. The air movement device may be a fan within the air duct, to cause air flow through the condenser and out the exit port. The air has a dew point, and the evaporator temperature is at that dew point or less, to cause liquid water to condense on the evaporator's exterior surface. The intermediate port of the air duct is between the evaporator and condenser, such that air can enter the air duct by at least two paths: through the entry port and evaporator, and through the intermediate port which bypasses the evaporator.
