Abstract:
1. A method of condensing water, comprising: passing a fluid mixture comprising water vapor into a gas flow channel in a condenser, wherein the condenser comprises forming a liquid in the liquid flow path; and passing coolant through the cooling channel with a pressure drop through the cooling channel of no more than 4 inches (10 cm) of water column, and at least one of the following: (1) the energy density, calculated from the volume of the sum of the cooling channel and the gas flow channel, including the volume of walls defining the cooling channel, is at least 2.0 W/cm or (2) the specific energy, calculated from the weight of the materials defining the cooling channel and the gas flow channel, is at least 1000 W/kg, or (3) the overall mean heat transfer coefficient is at least 500 W/cm or (4) at least 70% of the water vapor in the feed stream condenses into a liquid.
