Simulasi Distribusi Temperatur pada Cold Storage Hortikultura Menggunakan AC Split 1 PK dengan Software Ansys

Abstract

This study aims to analyze the temperature distribution in a horticultural cold storage system that uses a 1 PK split air conditioner as the main cooling source. The simulation was conducted using ANSYS software to model the cold airflow and predict the temperature distribution pattern inside the storage room. The modeling stages included creating the room geometry, setting boundary conditions, and applying thermal parameters that correspond to the operational conditions of the cooling system. This analysis is important because uneven temperature distribution can reduce the quality of horticultural commodities that are sensitive to temperature fluctuations. The simulation results show that the airflow tends to be concentrated in the central area of the room, causing this region to cool faster compared to the corners and lower parts of the storage space. This condition leads to non-uniform temperature distribution, with several zones remaining at higher temperatures due to the airflow not reaching the entire volume of the room effectively. To improve cooling uniformity, design modifications such as adding airflow guides or adjusting the AC unit position are required. These findings indicate that a simple cold storage system using a split AC still needs further optimization to maintain stable temperatures in accordance with horticultural storage standards. This research is expected to serve as a reference for developing efficient small-scale cold storage systems.
