| Abstract: | A new type of heat transfer surface for vapor condensation-fluted surface with thin porous coatings was proposed in this paper.A comparative study between fluted surface with thin porous coatings and the plain surface was carried out,and the experimental results show that the enhancement of condensation is quite obvious.To equip the condenser with this new type surface to solar heat pump,the coefficient of performance (COP) will be increased and the energy efficiency will be raised.In addition,in view of the engineering practice,the prospect of this new condenser was also discussed. |
