Abstract: Aiming at the problem of heat supply in the adsorption refrigeration system, the suns motion was analyzed, the tracking angular coordinate system and its motion equation were established.The design scheme of tracking angle transmission system and altitude angle transmission system in the singleshaft slot solar tracking system was presented. By using the builtin automatic calculation, fitting parameters, such as high angle, azimuth angle and noon time,the system controlled by SCM was investigated,which can automatically calculate angle difference according to the interval time. The running stability and tracking accuracy were evaluated on the design and manufacture of the prototype of the tracking system,the sun tracking was tested.The results indicate that the tracking system is stable and reliable, with less human intervention, high tracking accuracy, and the system integrating thermal performance is good.

Key words: tracking angle; singleshaft slot; high angle transmission system; tracking angle transmission system; control system
