Summary

Adsorption chillers are a promising option for environmentally friendly data centre cooling allowing for high energy efficiency. Waste heat from liquid cooled CPUs (~60 °C) drives the cooling for auxiliary loads (~20 °C) with heat rejection around 30 °C. Adsorption properties of the metal-­organic frame work (MOF) aluminium fumarate largely outperform the state-­of-­the-­art material silica gel at these temperatures. With adsorbent coatings, volume and mass specific cooling power may be increased to reduce specific costs.
Samples were prepare with a binder-­based aluminium fumarate coating in three different thicknesses (140–610 µm) and measured for adsorption dynamics with large-­temperature-­jump-­experiments. Uptake-­times (15-­85%) are in the range of 9–78 s. On a full scale heat exchanger expected volume and adsorbent mass specific cooling powers are 200–700 W l-­1 and 1.3–14 kW kg-­1 – an increase to state-­of-­the-­art of 3–10 times and >10 times at reasonable cooling COPs of 0.47–0.57.
