摘要： Corridors play an important role in the mechanized production of fruits and vegetables in solar greenhouse clusters. A corridor structure that is suitable for the automated production of solar greenhouse clusters is designed in this paper. To increase the corridor's ventilation efficiency and enhance the temperature environment, the computational fluid dynamics method is applied to analyze the effects of corridor structure, ventilation mode, wind speed, and direction on internal temperature and humidity. Studies have indicated that an erroneous layout of the corridor structure may result in the formation of accumulated temperature and heat concentration inside, and ventilation within the corridor is essential. The corridor's ideal dimensions are 3.2 m high by 5 m wide, and it has an internal wind speed and cooling rate that are superior to other structural factors. The ventilation method adopts a combination of top and bottom ventilation, and when the bottom window opening is 70%, there is a good ventilation effect inside the corridor. The corridor has an excellent ventilation effect when the wind speed is 2 m/s and the wind direction is east or west. This study supports the intensive and sustainable growth of greenhouse vegetable production by providing guidance for the planning and corridor design of solar greenhouse clusters.
