Abstract

As a series of high performance heat pump R and D as requested by the NEDO, the electrohydrodynamical (EHD) effect being applied to a shell-tube type heat exchanger, experiment to put it to practical use was made under a high temperature and high pressure condition to assume the heat pump. Design and manufacture being made of a 50kW class shell-tube type EHD condenser, the use of C {sub 6} F {sub 14} at 150 centigrade in temperature had the condensation heat transfer attain in enhancement ratio, at the highest, to six times as high as conventional. At that time, the consumed power at the helical wire with-lattice electrode was 0.0001% of the converted quantity of heat so that it could be limited to a negligibly very small value. For the EHD condenser, the condensation heat transfer enhancement method with use of the helical wire with-lattice electrode had its enhancement performance known to be effective in case that the heat transfer tube was long or that the medium was small in condensation latent heat. As a heat pump use condenser, there was known not to occur degradation in condensation heat transfer performance nor large enlargement in consumed power by lubrication oil,  More>>
