Abstract: A valve includes a housing which defines openings for the inlet and outlet of a fluid. The valve also includes a sleeve for controlling the circulation of the fluid through the housing. The movement of the sleeve along its axis is controlled by a thermostatic element.

Abstract: A method of operating a heat exchanger is disclosed in which an electric field is applied to a hydrophobic surface having condensed water droplets thereon to reduce a contact angle between the individual droplet surfaces and the hydrophobic surface, and to increase droplet surface energy to a second surface energy level.

The third surface energy level is greater than the first surface energy level and greater than a surface energy level for a free droplet. A portion of the droplet surface energy is converted to kinetic energy to detach droplets from the hydrophobic surface. The detached droplets are removed from the heat rejection side fluid flow path.
