摘　　要：在现有教学培养环节,一般只讲解建筑冷热源系统在设计工况下的相关知识,部分负荷下的运行调节作为难点内容很难讲解清楚,而培养高质量的运行管理人员是冷热源机房高效节能运行的关键。在冷热源系统优化设计与运行调节虚拟仿真实验中开发了变工况运行调节模块,介绍了建筑冷热源系统虚拟仿真实验模块、冷热源系统变工况运行调节方法、冷热源系统变工况虚拟运行调节及主要设备运行功率计算与显示。基于水泵工作点确定方法这一核心知识点,针对启动工况、设计工况、部分负荷工况,可将冷热源系统的实际调节操作与理论工作点的变化通过人机交互操作直观深刻地展示出来,使学生能掌握部分负荷工况下冷热源输配系统的变流量运行原理与操作。In the existing university teaching and training link,generally only explains the relevant knowledge of the building cold and heat source system under the design conditions,and the operation adjustment under partial load is usually too difficult to explain.However,the training of high-quality operation and management personnel is the key to the high-efficiency and energy-saving operation of the cold and heat source rooms.Develops the operation adjustment module under variable conditions in the virtual reality experiment of cold and heat source system optimization design and operation regulation.Presents the virtual reality experiment module of the building cold and heat source system,the method of operation adjustment of the cold and heat source system under variable conditions,the virtual operation adjustment of the cold and heat source system under variable conditions,and the calculation and display of operation power of the main equipment.Based on the core knowledge of determining working point of water pumps,the actual regulation operation and the changes of theoretical working point of cold and heat source system can be shown directly and profoundly through man-machine interactive operation under start condition,design condition and partial load condition,so students can master the variable flow operation principle and operation of the transmission and distribution system of cold and heat source under partial load conditions.
