This paper investigates the use of a hybrid desiccant cooling system as a means of reducing the energy required to provide air conditioning in commercial buildings. Mathematical models for each of the hybrid system components are presented, including the desiccant dehumidifier, the indirect evaporative cooler and the vapor compression cooling unit. The system operation is described. Some of the factors which influence the performance of the hybrid system are discussed. These factors include the ambient temperature and humidity, and the size of the sensible and latent cooling loads. Cooling system simulation results are presented for Phoenix, AZ and Miami, FL. It is shown that the hybrid system can reduce the energy consumption for cooling by about 50% in these locations.
