Understanding the Influence of Ambient Temperature on O.R.C. Cooling Efficiency
Impact of Ambient Temperature Differentials on O.R.C. Efficiency
The efficiency of an O.R.C. cycle is significantly influenced by the ambient temperature differentials it encounters. Higher temperature differentials can enhance the cycle’s efficiency by allowing for increased heat transfer rates and improved power generation. However, high temperatures can also lead to operational challenges such as increased thermal stresses on system components and potential performance degradation over time. On the other hand, lower temperature differentials may reduce the efficiency of the cycle, affecting power output and overall system performance.
