Abstract
A vertical plant factory has problems of either producing the uneven quality crops due to the temperature deviation between the upper and lower beds or increasing energy consumption after prolonged cultivation. The conventional heating methods wherein an air conditioning device and external circulation fans are simultaneously operated are effective in maintaining the cultivation environment in the entire area. However, this method has a limit in improving the air flow locally stagnant inside the cultivation beds. In this study, a CFD-based internal fan control simulation is proposed in order to improve the cultivation environment inside a plant factory. The changes in the temperature and air flow of the entire area in the facility as well as in each growing bed were analyzed with a simulation. Based on the simulation, the improvement in the cultivation environment by the internal fans was verified. The analysis results showed that the method with the additional internal fans was effective in maintaining the uniform cultivation environment by improving the air flow locally stagnant in the entire facility and inside the growing beds.
