摘要

Evaporative cooling technique can reduce global CO2, CFC and other greenhouse gas emissions, protect global environment, cut down building energy consumption and depress back electrde power in summer, reduce first cost and operating cost of air conditioning and improve indoor air quality, but the wall surface hydrophilic of heat exchanger is poor, so efficiency of indirect evaporative cooler is decreased. Porous ceramics could be one of the potential materials used for evaporative cooling due to its advanced properties, i.e., high capacity force, high thermal conductivity, waterproof, durability and capillarity. Porous ceramics may be combined with a thin fill made of the same material to avoid penetration of moisture when being used in indirect evaporation systems. To improve the wall surface hydrophilie of tube type indirect evaporative cooler, this paper puts forward the use of porous ceramics material, realizes organic combination of porous ceramics and evaporative cooling technique, and carries out the design calculation of porous ceramics tube type dew point indirect evaporative cooler from aspects of primary and secondary air volume, primary and secondary air status parameters, structure of cooler, heat transfer of solid porous ceramic tubes and resistance of cooler.
