This chapter shows the numerical investigation of the developed solar- DHVAC system applied in the East Asian climatic conditions with two different desiccant wheel coating materials-the Silica Gel (SiO2) and the Titanium Dioxide (TiO2). The system was applied in temperate climate (Beijing and Tokyo), subtropical climate (Taipei and Hong Kong) and tropical climate (Manila and Singapore). The study showed that the specification of the solar-DHVAC system varies depending on the climatic conditions. In the comparison of the two materials, it was found that the TiO2 can support lower indoor temperature and humidity ratio than the SiO2 with the same specification of the solar thermal system and DHVAC system. In general, the solar-DHVAC system can provide the required indoor temperature and humidity ratio. However, for the hot and humid climate such as in tropical, large size of the solar thermal system is needed. In addition, higher volumetric flow of air to support the high cooling load is required.
