Study on Adsorption Desiccant Based Hybrid Air Conditioning System

The desiccant based hybrid air conditioning system can control temperature and humidity separately, which consists of adsorption desiccant system and compression type refrigeration system. The adsorption desiccant system obtains the moisture power, and the compression type refrigeration can obtain sensible heat load. Generally, the regenerated energy consumption of the desiccant wheel is very large in the total energy consumption, using electric power, waste heat or renewable energy (solar etc). Heat recovery from the condenser considered as only regenerated energy in the new type adsorption desiccant based hybrid air conditioning system is proposed and discussed in this paper. This method can reduce much energy consumption, and make the air conditioning system structure simple.
