集成式热交换系统的控制方法
摘要：
本发明公开了一种集成式热交换系统的控制方法，该系统包括压缩机、热交换器、膨胀阀，通过管道互相连接组成回路，冷媒在回路中循环流动，其系统中包括至少三个热交换器；系统中包括一组可切换阀门组合，通过改变可切换阀门组合的流道来改变内部回路上热交换器的冷媒流向，从而使系统具有单冷、单热、冷热联供三种运行模式；其特征在于：从其他模式切换到单冷模式时，提前5-10秒关闭可切换阀门组合流入端之前的热交换器，再改变可切换阀门组合的流道。通过本发明的控制方法，在阀门组合切换之前，有一段时间使流入端处的冷媒气化，这样整个可切换阀门组合内的冷媒都是气态的，切换更加顺畅快捷。
摘要（英）：

The invention discloses a control method of an integrated heat exchange system. The system comprises a compressor, heat exchangers and an expansion valve which are mutually connected through pipelines to form a loop, a cooling medium circularly flows in the loop, the system comprises at least three heat exchangers as well as a set of switchable valve assembly, and the flowing direction of the cooling medium of the heat exchangers on the inner loop is changed by changing a flow passage of the switchable valve assembly so that the system has three operation modes of single cold supply, single heat supply and combined cold-heat supply. The control method of the integrated heat exchange system is characterized in that: when another mode is switched to the single cold mode, the heat exchangers in front of the flow-in end of the switchable valve assembly are closed 5-10s in advance, and then the flow passage of the switchable valve assembly is changed. Through the control method of the invention, the cooling medium at the flow-in end is gasified in a period of time before switching the valve assembly so that the cooling medium in the whole switchable valve assembly is gaseous, and switching is smoother and rapider.
