It avoids the energy loss during two times energy conversion processes between wind energy and electric energy. To enlarge working efficiency of the wind machine, a generator is combined into the wind forced chiller to build a dual system. The integrated wind generator can use the wind energy, which is not strong enough to drive the wind forced chiller effectively. An integrated programmable logic controller (PLC) is applied in this wind forced dual system to drive the wind forced chiller and the wind generator in terms of the rotational speed separately. The results show that working efficiency of windchiller is ca. 3.9% and generator is ca. 0.05% in the all wind field. The low working efficiency of windchiller is due to the lower working efficiency home-made wind machine and larger working torque requirement of windchiller. The low working efficiency of wind generator is due to the too slow rotational speed. Moreover, this research built a slow speed wind tunnel to measure the working efficiency of the home-made wind machine. Size reduction of the angular vanes in accordance with analogical theorem were made for measurement. The results show that the 45 degree angular vane has the best working efficiency 10.2% and the applied wind machine with 35 degree angular vane is 8.6%. A torsional dynamometer is also built for determining the the torque of the wind generator, which supports significant data for the future system optimization.
