摘要:该试验系统的设计是为了研究风冷压缩冷凝机组性能,检测制冷系统的性能,并提出针对性的改善措施,最终使系统的性能得到优化。

   试验方法采用“第二制冷剂量热器法”,其原理是制冷系统产生的制冷量与电加热器产生的热量相交换,达到平衡时,通过测量电加热器而得出的制冷量的一种间接试验方法。试验系统设置有数据自动采集系统。

   本次设计的主要任务是对试验室负荷进行计算,设计房间尺寸,进行总体布置。并且试验台的主要部件——量热器进行计算。通过热力计算,得出制冷量等性能指标。再根据传热学和换热器设计等有关文献,计算出蒸发盘管的传热系数,从而得出蒸发盘管面积,并对其结构设计。接下来,进行了制冷系统节流机构和附属设备的选型。

Abstract:The test system is designed to study the performance of condensing units, air-cooled compression test the performance of the refrigeration system, and puts forward specific improvement measures, eventually make the system performance was optimized. 

  Test method adopts "the second refrigerants calorimeter method", its principle is the refrigerating capacity and refrigeration system produce electric heaters are exchanged heat generation, balance, measured by the electric heater and the refrigerating capacity that an indirect test method. Test system Settings are automatically data acquisition system. 

  The design of the main task is to load calculation, laboratory design room size, in overall layout. And the main part -- calorimeter test is calculated. Through the thermodynamic calculation indicates that such performance index refrigeration. And then based on heat transfer and heat exchanger design and other relevant documents, calculated evaporation coil, so as to obtain the heat transfer coefficient evaporation coil area, and its structure design. Next, the refrigeration system the throttle body and accessory equipment selection. 

Key words: Air-cooled compression ,testing system,calorimeter, refrigeration system
