The effect of an electric field on boiling refrigerant R11 was investigated experimentally. The test section consisted of a flat plate and a single tube with several rows of electrode wire. The influence of refrigerant oil, surface roughness of the test tube, and polarity of an applied voltage on the heat transfer performance were studied. The following results were obtained: (1) as the applied voltage increased, the number of boiling bubbles decreased, but the heat transfer coefficient increased; (2) there was no deterioration of heat transfer by the oil contamination; (3) the polarity of the applied voltage affected the boiling heat transfer.
