Abstract:
In this study, the effects of circulating fan setting conditions, such as number of fans and installation position and angle, on the distributions of air speed and temperature in the agricultural greenhouse, were investigated experimentally and numerically. The environment data of air speed, temperature, humidity and thermal radiation of a demonstrative greenhouse acquired via continuous automated measurement were integrated with micro-climate CFD simulation to reveal the optimal control rule of the air-conditioning instruments. The results show that the unformities of air speed and temperature were improved substantially; the mean air speed increased from 0.26 m/s in the original setting to 0.62 m/s with a standard deviation of 0.09 m/s, and the temperature variation became lower than 0.3°C.
