A temperature sensing circuit adapted for a memory device and including an oscillator, a count circuit, a control circuit, a sense circuit and a select circuit is provided. The oscillator provides an oscillation signal. The count circuit counts the oscillation signal to generate a first count signal, and generates a second count signal. The count circuit performs a logic operation on the second count signal to generate an enable signal and a sensing adjustment signal. The sense circuit generates a reference temperature voltage by dividing a reference voltage according to the sensing adjustment signal, and compares the reference temperature voltage and a monitor voltage according to the enable signal to generate a determination signal. The select circuit dynamically selects one of the oscillation signal and the first count signal according to the determination signal, and generates a pulse of a refresh request signal according to the dynamically selected one of the oscillation signal and the first count signal.

A method includes receiving temperature measurements from multiple temperature sensors in a power supply system that includes multiple coils arranged in a series downstream of a turbine, each coil configured to receive thermal energy from an air stream exhausted from the turbine as the air stream moves toward a data center, each coil associated with at least one fluid loop. The method also includes using a first subset of the temperature measurements to determine a blended fluid mix from a primary fluid path and a heated fluid reservoir in order to obtain a predetermined leaving fluid temperature at a first coil of the multiple coils. The method further includes controlling a position of one or more valves associated with the primary fluid path and the heated fluid reservoir to achieve the determined blended fluid mix.
