Impact of Refrigerant Charge Loss on System Efficiency
Energy efficiency loss with refrigerant charge loss. Energy efficiency loss is estimated here as the % loss in COP relative to the COP at full refrigerant charge. It is important to note that the effect of refrigerant charge on energy efficiency loss is dependent on the specific systems and the temperature conditions. For the studies whose data is represented in this graph, the efficiency loss can vary as little as 4%, at 10% refrigerant loss, and by greater than 30%, as the charge loss gets beyond 40%, based on the conditions. Darker blue points represent studies averaged across multiple temperature conditions, while the lighter points represent tests at single controlled temperatures
