制冷空调综合实验装置的设计

Development of the Integrative Refrigerating System Used for Experiments

介绍了江苏科技大学热能动力实验中心设计开发的一套试验用制冷空调综合实验装置。该装置设计合理、技术先进、测试精度高,可以开设多个制冷空调实验。其采用了冷却水模拟热负荷的方法,使系统简化且节约了成本;控制部分使用了变频调节能量、PID调节系统参数等现代化技术,操作灵活、方便,从而为教学和科研提供了良好的条件。其设计技术及试验结果可供制冷空调产品开发、技术改造及类似试验装置设计时参考。

The design of air - condition and refrigerating system used for experiments and parts of experimental results on it were introduced. In the system, the method of simulating heat load with the heat of cooling water was applied to simplify the system and to save the cost. And the modem technologies such as regulating the cooling amount by frequency converter, adjusting system parameters by PID governor, and etc, were used to improve operating and controlling performances. So it provided good conditions for teaching research. The designing techniques of it and experimental results on it could provide convenience for the development of refrigerating and air control products, the technical improvement of old products, and the design of similar experimental devices.
