Abstract

The paper presents investigation on a small size solar cold storage built at Politeknik Negeri Bali. The solar cold storage comprises a grid-connected PV system and a cold storage using R290 with power input specified for 2.5 kW. The investigation includes potential of renewable energy generation, cold storage energy demand, grid energy imported and renewable energy exported. The PV system is specified for a peak capacity of 3.1 kW. Average instant AC power generation during the day is 1.66 kW with maximum power generations as high as 2.55 kW. Daily renewable energy generation in the selected highest day can reach 18.5 kWh. The investigation results also showed the cold storage consumed 39.8 kWh electricity in a day. During the day (PV production time), the cold storage requires for about 17.5 kWh which is lower than the energy generated from the PV system. However, the cold storage still needs imported energy due to off and defrost cycles. It is about 69% renewable energy generation can be applied but the rest of 31% must be exported to the grid. This results show the use of renewable energy storage system can improve the utilization of renewable energy to drive the cold storage.
