Abstract

Cooling systems such as split AC are currently one of the devices widely used in commercial and residential buildings. However, high energy consumption, especially during peak loads, is a major problem that has a direct impact on energy efficiency and operational costs. Therefore, innovation is needed to improve AC work efficiency, one of which is through the use of thermal energy storage technology using Phase Change Material (PCM). This study aims to determine the influence of PCM on the efficiency of the air conditioning system, especially in reducing energy consumption. Subsequently, the control conditions were tested by operating the AC system under conditions without bio PCMs at no load and at the specified load. Testing with bio PCM is done by operating the AC system while adding bio PCM at the same load. Each test scenario (with and without bio PCM) will be repeated several times for 8 hours to ensure data reliability and minimise random variations. The results showed that the COP of AC without bio PCM, without bio PCM with load, with bio PCM, and with bio PCM and load are respectively 4.68, 4.65, 4.61, and 4.63. The energy consumption is, respectively, 0.06528 kWh, 0.06663 kWh, 0.0673 kWh, and 0.0665 kWh. It can be said that bio PCM resists an increase in the cooling load, thereby resisting an increase in energy consumption, increasing the COP of the air conditioning system.
