Space environmental control system is planted in a plant, is to control to the air to the greenhouse space Zhi Zai, and is included U-shaped pressure fan, temperature-sensitive sticker, humidity sensor and control mould group. Wherein, it is the chamber humidity value for being sensed and being obtained according to the greenhouse temperature value and humidity sensor that temperature-sensitive sticker senses and obtains using control mould group that space environmental control system is planted in the plant of this creation, the heat exchanger and humidifier in the control setting U-shaped pressure fan of what are removed, so that the air in the greenhouse space Zhi Zai can be controlled by the circulation by U-shaped pressure fan.一種植栽空間環境控制系統，係用以對溫室植栽空間之空氣進行控制，並包含U型送風機、溫度感測器、濕度感測器與控制模組。其中，本創作之植栽空間環境控制系統是利用控制模組依據溫度感測器所感測而得之溫室溫度值與濕度感測器所感測而得之溫室濕度值，去控制設置於U型送風機內之熱交換器與加濕裝置，以使溫室植栽空間內之空氣可藉由通過U型送風機的循環而受到控制。
