汽车空调热力膨胀阀是汽车空调制冷系统中的重要部件,它控制着系统的流量及维持高低压差,长期以来采用的实验研究方法有许多局限性。本文从数值计算的角度对该部件进行分析求解,并与实验的结果进行了比较发现,计算结果与实验吻合较好,并从所求得的流场和压力场的分布中提出了改进阀设计的建议。
Automotive air conditioning thermal expansion valve is an important component of automotive air conditioning and refrigeration systems, it controls the flow of the system and maintain high and low pressure, the experimental research methods used for a long time there are many limitations. This paper analyzes and solves this part from the point of view of numerical calculation and compares it with the experimental results. It is found that the calculated results are in good agreement with the experiment. From the obtained distribution of flow field and pressure field, the improved valve design Suggestions.
