节流阀的用途是对冷凝器输出的高压液态制冷剂进行节流降压和调节流量。
Throttle valve role is the export of high-pressure liquid coolant condensers to reduce and regulate the flow of relief.
高压气态制冷剂在冷凝器中向冷却介质放热被凝结为液态后，经节流装置减压降温进入蒸发器；
High pressure gas refrigerants in the condenser cooling medium heat to be setting for liquid, through the throttle device reduced pressure cooling into the evaporator;
这一高压高温气体接着向冷凝器转移。冷凝器是一个大的换热器，通常位于引擎散热器的前端。
This high pressure high temperature gas then travels onwards to the condenser - a large heat exchanger usually located in front of the engine radiator.
