Patent ID: 7066241

Claim:
A method of enabling a hot hydronic fluid to transfer heat to a second fluid to cause desorption in the second fluid and generate an upward flowing vapor, comprising, forming a horizontal first grid of closely spaced narrow diameter hollow tubes; placing a plurality of similar grids in a horizontal position and in close vertical spaced relation to the first grid and to each other; fluidly interconnecting the tubes of each grid; passing a hot hydronic fluid upwardly for movement through the fluidly interconnected grids; taking a second fluid and continuously disbursing the fluid substantially over the first grid wherein the second fluid will releasably cling to the tubes of the first grid, and thence drop sequentially to releasably cling sequentially to the tubes of remaining grids; maintaining an open space between each grid so that when quantities of the second fluid sequentially release from the tubes of the first grid, they can fall directly and freely by gravity for impingement on a lower grid to be physically intermixed by the impingement; and continuing the impingement as quantities of said second fluid progressively drop by gravity onto the grids; whereupon each impingement will progressively and sequentially intermix the second fluid to cause desorption and generate an upward flowing vapor.
