The present invention provides a control method of an electronic expansion valve integrally equipped with a PT sensor. According to the present invention, vibration can be avoided without changing existing parts by integrating a PT sensor that can measure the pressure and temperature of a refrigerant leaking from an evaporator to form an electronic expansion valve, the length of a wiring is reduced as well as simplified, so that the refrigerant can be efficiently controlled. Moreover, the electronic expansion valve has high compatibility as the electronic expansion valve can be optioned with the same parts as the existing machine block type expansion valve system. In addition, the opening degree of a throttle flow path is controlled by comparing the current degree of superheat with the target degree of superheat through external temperature.
본 발명은 증발기에서 유출한 냉매의 압력 및 온도를 측정할 수 있는 PT센서를 일체화로 전자팽창밸브를 구성하여, 기존 부품의 변경 없이 진동 회피가 가능하고, 와이어링의 길이절감은 물론 단순화되어, 냉매를 효율적으로 제어할 수 있고, 기존의 기계블록형 팽창밸브 시스템과 동일한 부품으로 옵션화 할 수 있어 호환성이 높고, 외기온도를 통해 현재 과열도과 목표(설정) 과열도를 비교하여 교축유로의 열림량이 제어되는 PT센서를 일체로 구비한 전자식 팽창밸브의 제어방법을 제공한다.
