摘要
四通阀是压差驱动阀,依靠活塞两端的压力差推动活塞来实现换向,四通阀换向压力差与系统的冷媒流量有关。通过建立模型并结合实验,量化分析四通阀可靠换向与系统冷媒流量的关系。
The Four-way Valve is a kind of pressure-driven valve,which depends on the pressure difference from end to end across the piston to push the piston and achieve commutation.The pressure difference for the commutation of the Four-way Valve is related to the refrigerant flow of the system.In this paper,by modeling and binding experiments,to make quantitative analysis about the exact relationships between the reliable commutation of the Four-way Valve and the refrigerant flow of the system.
