Abstract
A novel method of deicing utilizing a fins-on-tubes type evaporator/heat exchanger system that is optimized for energy-saving inductive heating thereof, by configuring it to increase its resistance to a value at which the system's reactance at its working frequency is comparable to its electrical resistance. The system includes a set of tubes configured for flow of cooling material therethrough, and also includes a set of fins positioned and disposed perpendicular to, and along, the tubes, in such a way that at least a portion of the fins comprises longitudinal excisions therein.
Claims12
A method for deicing a fins-on-tubes evaporator system with a predetermined electrical resistance, the method comprising:
- inducing an electric current in the fins-on-tubes evaporator system, wherein the system comprises:
- a plurality of cooling material flow tubes electrically connected in parallel to one another;
- wherein each of the cooling material flow tubes comprises at least a first electrically conductive section electrically connected in series to a second electrically conductive section, and wherein inducing the electric current causes the electric current to flow through the first electrically conductive section and the second electrically conductive section;
- and
- a plurality of fins attached to the cooling material flow tubes.
