Performance Study of Air Conditioning System Using Solar Power Photovoltaic as Environmentally Friendly Alternatives

Nowadays, solar powered air conditioning machines have made increasing progress as air conditioning systems are almost a must in every building in Indonesia. Indonesia is a tropical area that can receive sunlight all year round. This study examines the design and performance of a solar-powered air conditioning system that is integrated with a photovoltaic (PV) system consisting of PV panels, solar chargers, DC power controllers/inverters and batteries. This air conditioning system can be used in non-electrical areas. The first step in this research is the calculation of the cooling load for the space to be conditioned and obtained about 1 ton of refrigeration (3.52 kW). Based on this cooling load, a photovoltaic (PV) system has been estimated and constructed with the necessary connections. Data logging systems have been used to measure the temperature of the main components in the cycle such as the compressor inlet and outlet as well as the evaporator and condenser. The input power for the system as well as the coefficient of performance (COP) for the system under Indonesian climatic conditions are measured throughout the day. The coefficient of performance varies from 2.9 to 8.5 for the system and this result is compared with the performance of the conventional syste
