The study analyzed a mechanical ventilation system in greenhouses, showing excellent performance and reliable temperature control within the indoor environment, confirming its potential for efficient management of internal temperature.
Proper management of the microclimatic environment plays a main role for a more rational use of energy in greenhouses. In particular, ventilation systems in controlled environment agriculture (CEA) are essential to make the indoor environment as compatible as possible with production needs. In this study, a prototype of mechanical ventilation (SIVeMeC: Integrated System for Controlled Mechanical Ventilation) was analysed in cooling mode by simulating, through two climatic rooms, typical Summer outdoor temperature (i.e., 29 degrees C, 32 degrees C, 35 degrees C, 38 degrees C and 40 degrees C) and an indoor set-point of 24 degrees C. The main results show a very high performance of the system and reliable temperature control within the confined environment. Finally, a comparison was made with a representative commercial unit, which confirmed the suitability of SIVeMeC to efficiently manage the internal temperature.
