Computational fluid dynamics (CFD) plays an increasingly important role in designing the agriculture control environment structure in the past few years. A plant factory is a fully enclosed controlled environment agriculture structure developed to create optimum growing conditions for crops. Previous studies have proven that the CFD technique was able to analyse and predict the internal climate of the plant factory in the designing stage before the actual plant was built. Uniformity of airflow and temperature distribution is important in plant factories as it is responsible for creating an optimum and uniform growing condition for crops. The objective of the study is to find the best location of the air-conditioner and air outlet that produce the optimum air flow and cold air distribution inside the container size plant factory with a high-density planting. CFD simulation was conducted to analyse the changes in air flow characteristics and temperature distribution inside the plant factory with different locations of air-conditioner and air outlet before the actual plant factory was build. Three alternative locations i.e., location 1, 2 and 3 were simulated to improve the uniformity of airflow and temperature distribution. Temperature and airflow data was recorded and compare between these alternative locations. The location of the air-conditioner and air outlet that produced the optimum airflow and temperature distribution inside the plant factory was identified based on the alternative that produce lowest average temperature and higher air flow.

Abstract

Computational fluid dynamics (CFD) plays an increasingly important role in designing the agriculture control environment structure in the past few years. A plant factory is a fully enclosed controlled environment agriculture structure developed to create optimum growing conditions for crops. Previous studies have proven that the CFD technique was able to analyse and predict the internal climate of the plant factory in the designing stage before the actual plant was built. Uniformity of airflow and temperature distribution is important in plant factories as it is responsible for creating an optimum and uniform growing condition for crops. The objective of the study is to find the best location of the air-conditioner and air outlet that produce the optimum air flow and cold air distribution inside the container size plant factory with a high-density planting. CFD simulation was conducted to analyse the changes in air flow characteristics and temperature distribution inside the plant factory with different locations of air-conditioner and air outlet before the actual plant factory was build. Three alternative locations i.e., location 1, 2 and 3 were simulated to improve the uniformity of airflow and temperature distribution. Temperature and airflow data was recorded and compare between these alternative locations. The location of the air-conditioner and air outlet that produced the optimum airflow and temperature distribution inside the plant factory was identified based on the alternative that produce lowest average temperature and higher air flow.
