Thermal Time Shifting: Decreasing Data Center Cooling Costs with Phase-Change Materials

Matt Skach, Manish Arora, Chang-Hong Hsu, Qi Li, Dean Tullsen, Lingjia Tang, Jason Mars
2017 IEEE Internet Computing  
As data centers increase in size and computational capacity, their growth comes at a cost: an increasing thermal load that must be removed to prevent overheating.  ...  Here, the authors propose using phase-change materials (PCMs) to shape a data center's thermal load, absorbing and releasing heat when it's advantageous.  ...  night, or even leverage free cooling in regions with low ambient temperatures. 3, 4 Last, we can use PCM in a thermally constrained data center to handle short peaks above the thermal limit while still  ...
