The second part was about heat mass transfer models in moist sterilization process, from which the heat transport time could be theoretically calculated.

Numerical method is used in this paper to solve the heat and mass transfer coupled equations, the temperature and moisture fields in three periods of drying moist porous materials are obtained.

Whole cooling load of automotive air conditioner consists of three parts, vehicle body heat transfer and ventilating new air heat and condensing moist air heat.
