The results of laboratory measurements on the performance of the HVAC system powered by solar air heater, solar cell and wind generator, are described. Experiments were performed in various weather conditions both in winter and summer. The experimental results show that 30-90% of thermal energy to regenerate the desiccant in this system and 20-65% of the energy to power the system were supplied by natural energy in summer, and 30-97% of the energy to power the system was supplied by natural energy in winter. The results of measurements on the performance of a desiccant dehumidifier unit with solar air collectors are also described. Room exhaust air is used to cool the 17% of the desiccant rotor area in this unit. Experimantal results show that the amount of dehumidification was increased by 6% and the amount of energy to cool the air was decreased by 8% by this rotor cooling process.
