Abstract: Until now, the technical development of wind force is mainly combined with electrical generator and already achieves the skillful technique in application. In this paper the newly developed windchiller directly applies the mechanical energy of wind force for refrigeration instead of the traditional electrical/mechanical energy conversion. The devise avoids energy loss during the two to-and-fro energy conversion processes between wind force and electrical energy. The special finished wind machine applies the technique with two directions to capture the wind force, the faced and its opposite directions, in the fans design. Between the wind turbine and the compressor, a transmission system with a fixed conversion rate 1:20 was used for acceleration. After the combination with open-type reciprocating compressor, the wind forced chiller is built. The windchiller increases the working efficiency in comparison with the refrigerating system of indirect connection from wind generator to refrigerator and ignores the unstable property of wind force. The strength of wind force influences only the windchiller's efficiency; the stronger wind force, the larger windchiller's efficiency. The experimental results show the newly developed windchiller's efficiency ca. 21.28%, which agrees to the pre-evaluation and achieves a high efficiency.
