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.
Claims1
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 separate cooling material flow circuits connected in parallel to one another and at least a first electrically conductive section and a second electrically conductive section, and wherein inducing the electric current causes the electric current to flow first through the first electrically conductive section then through the second electrically conductive section, thus causing an increase in the predetermined electrical resistance of the system.
