A Dynamic Thermal-Allocation Solution to the Complex Economic Benefit for a Data Center

Table 1

Description of two thermal evaluation indexes.

Thermal evaluation index	RHI	RTI
Expression
Evaluation criterion	RHI∈(0, 1). The more the RHI approaches 1, the better the heat transfer, the less the mixing of cold and hot air, and the higher the utilization rate of air-cooling capacity is.	The more the RTI approaches 1, the better the air distribution is. When RTI >1, there is hot air backflow. While RTI <1, it indicates cold air bypass.
