Rancang Bangun Cold Storage Hortikultura Menggunakan AC Split 1 PK

Abstract

Cold storage is a low-temperature storage system that is widely used to maintain product quality by inhibiting the rate of quality decline. In the field of Mechanical Engineering, the study of refrigeration system performance is important to assess the efficiency and cooling capability of a system. This study aims to design and build a small-scale cold storage with room dimensions of 1.8m × 1.8m × 1.8m using a 1 PK split AC as a cooling unit. The research method includes calculating the cooling load, measuring the temperature distribution of the cold storage room, and analyzing the coefficient of performance (COP). Data were obtained through manufacturing planning. The results showed that the 1 PK split AC was able to maintain the cold storage temperature in the cooling temperature range of 5℃, but the system efficiency decreased with increasing cooling load and operating time. The COP value of 3.28 obtained indicated that the system is still suitable for use in small-scale cold storage applications with a maximum capacity of 92.54 kg. This research is expected to contribute to the development and optimization of a simple refrigeration system based on a split AC as an alternative cooling solution in small-scale cold storage.
