对热力膨胀阀、步进电机型膨胀阀以及电磁阀型膨胀阀在制冷系统开机以及稳定运行的情况进行了实验研究，结果表明电子膨胀阀适合用于系统综合控制器中；连续调节型的执行机构比离散调节型的执行机构更容易使过热度稳定；积分环节大大改善了过热度的控制品质。
The thermal expansion valve, stepper motor-type expansion valve and solenoid valve-type expansion valve in the refrigeration system boot and stable operation of the experimental study showed that the electronic expansion valve is suitable for use in the system controller; continuous adjustment The actuator is easier to stabilize the superheat than the actuator with the discrete actuator. The integral part greatly improves the control quality of superheat.
