Thermal performance is the ratio of achievable gross heat loss to the corrected value of actual average gross heat loss, expressed as a percentage. In the materials field, the thermal performance of PET chips and coke is affected by factors such as molecular weight distribution. Digital twin technology for thermal performance can be used for performance mapping and simulation of cooling systems. In power systems such as all-electric marine microgrids, the thermal performance of energy storage systems (ESS) has a significant impact on system operation and battery degradation.


Thermal performance is the ratio of optimal achievable gross heat loss to the corrected value of actual average gross heat loss, expressed as a percentage. Gross heat loss is the ratio of the total heat energy generated by the reactor to the total electrical energy generated by the generator within the same time interval. Thermal performance comprehensively reflects the heat transfer performance and thermal efficiency status of the unit.


This term refers to the characteristics of a substance or system under thermal influence. For example, the thermal performance of PET chips deteriorates as the molecular weight distribution broadens; borate-based passivating agents can significantly improve the thermal performance of coke.
