<![CDATA[Utilization of New Renewable Energy (EBT) today must be carried out because of its abundantpotential. One of the uses is to use energy storage with a heat pump system sourced from EBT. To supportthis, it is necessary to use a heat exchanger in an energy storage system which is expected to make theheating or cooling system faster with the right refrigerant. Therefore, a study was carried out using theapplication of a heat pump system with the addition of a heat exchanger as a place to store energyoriginating from Renewable Energy. The method used is process simulation using DWSIM. The refrigerantused is R-600a, R-407C. R-410a, R-22, and ammonia. Ammonia was chosen because it produces aCoefficient of Performance of 3.012 with a condenser outlet temperature of 102.854°C. The storagemedium used is silica sand.]]>
