AI Technical Summary

Problems solved by technology

[0004] Regardless of the type of air conditioner, there are two problems: the output deviation caused by the comparison test environment cannot be given; the output cooling capacity cannot be accurately quantified

Since the cooling capacity output by ordinary air conditioners does not have strict traceability, a specific mathematical model cannot be given, resulting in the inability to evaluate its uncertainty
