RP-1100 -- Control of Frost Accumulation in Refrigeration Equipment Using the Electrohydrodynamic (EHD) Technique PDF

ABSTRACT:

It is now well established that the electrohydrodynamic method can be effectively used to enhance heat transfer coefficients of air and refrigerants by several hundred percent depending on the geometry of the electrode, the heat transfer surface, flow conditions and the materials for the electrode/heat transfer surfaces. Its applicability to the control of frost accumulation on a flat plate surface needs further study. The EHD technique has broad applications of relevance to the refrigeration industry. Minimization of frost formation on refrigeration coils in most cases will increase the time interval between two defrosting cycles and thus improve the performance and life of the equipment.
