自然通风是降低日光温室内空气温度和湿度,提高二氧化碳浓度的有效手段。目前采用的自然通风方式大多数都是屋脊通风与前屋面底角通风相结合的方式。而在冬季,屋脊通风是日光温室最常用的通风方式。为了降低劳动强度,提高控制日光温室内环境的科学性和准确性,项目组在西北非耕地日光温室内采用了可根据室内温度高低分段控制风口大小的屋脊智能通风装置。 Natural ventilation is an effective means of reducing the temperature and humidity of air in a solar greenhouse and increasing the concentration of carbon dioxide. Most of the natural ventilation methods currently used are a combination of roof ventilation and ventilation at the front of the roof. In winter, roof ventilation is the most common method of ventilation in daylight greenhouses. In order to reduce the labor intensity and improve the scientific and accurate control of the environment inside the solar greenhouse, the project team adopted a roof intelligent ventilation device capable of controlling the tuyere size according to the indoor temperature in the non-cultivated solar greenhouse in the northwest.
