The present invention relates to a device for automatically opening and closing a vinyl greenhouse ventilation window, comprising: a lateral side window opening and closing unit which is installed to be able to move along a lateral side of a vinyl greenhouse to open and close a lateral side window formed on a lateral side of the vinyl greenhouse for ventilation of the vinyl greenhouse a sensor unit comprising a temperature sensor for measuring the temperature of the inside of the vinyl greenhouse and a controller which controls the operation of the lateral side window opening and closing unit in accordance with the temperature measured by the temperature sensor or a set time. The controller controls the operation pattern of the lateral side window opening and closing unit, when the lateral side window opening and closing unit is extended from the ground in a lateral side area of the vinyl greenhouse to a certain height and is located in an area of a skirt unit forming a lower portion of a lateral side window, and an operation pattern of the lateral side opening and closing unit, when the lateral side window opening and closing unit escapes from the area of the skirt unit and is located in an area of the lateral side window, to be different from each other. According to the present invention, the vinyl greenhouse environment control system enables ventilation to be automatically performed in accordance with temperature change inside the vinyl greenhouse or time, enables an opening and closing operation to be performed in a rapid manner in accordance with temperature change inside the vinyl greenhouse or time, and thus can provide a cultivation environment appropriate for cultivated crops.COPYRIGHT KIPO 2017본 발명은 비닐하우스 환기창 자동개폐장치에 관한 것으로서, 비닐하우스의 환기를 위해 상기 비닐하우스의 측면에 형성된 측창을 개폐할 수 있도록 상기 비닐하우스의 측면을 따라 상하로 이동 가능하게 설치된 측창개폐부와 상기 비닐하우스 내부의 온도를 측정하는 온도센서를 포함하는 센서부와 상기 온도센서에서 측정된 온도 또는 설정된 시각에 따라 상기 측창개폐부의 작동을 제어하는 컨트롤러를 구비하고, 상기 컨트롤러는 상기 측창개폐부가 상기 비닐하우스의 측면 영역 중에서 지면으로부터
