According to the present invention, disclosed is a control method of a step valve according to opening and closing a door. According to the present invention, the control method of a step valve according to opening and closing a door comprises the following steps of: grasping existence of a storage chamber of which a door is opened through a control unit; calculating an internal temperature increasing range of the storage chamber of which the door is opened through the control unit; and changing an alternating period of a step valve based on the internal temperature increasing range of the storage chamber of which the door is opened through the control unit. 본 발명은 도어개폐에 따른 스텝밸브 제어방법이 개시된다. 본 발명의 도어개폐에 따른 스텝밸브 제어방법은, 제어부가 도어가 개방된 저장실이 있는지 파악하는 단계; 상기 제어부가 상기 도어가 개방된 저장실의 고내 온도 상승폭을 산출하는 단계; 및 상기 제어부가 상기 도어가 개방된 저장실의 고내 온도 상승폭에 기초하여 스텝밸브의 교번주기를 변경하는 단계;를 포함하는 것을 특징으로 한다.
