Abstract: This invention is a novel air supply register that modulates the incoming air supply from the under floor air duct. This air register is able to monitor the air temperature leaving the server stack thereby improving the response time of the HVAC system. Since the register has adjustable louvers that can modulate the inlet air flow into the server stack; it will save energy by reducing the supply air to the server stack when the cool incoming air is not needed. This reduces hot spots in the data center because the cool incoming air can be directed to server racks that need cooling. This self-modulation of the air register is not available in conventional floor registers.

Abstract: This invention covers nanofluids. Nanofluids are a combination of particles between 1 and 100 nanometers, a surfactant and the base fluid. The nanoparticles for this invention are either pyrogenic nanoparticles or carbon nanotubes. These nanofluids improve the heat transfer of the base fluids. The base fluid can be ethylene glycol, or propylene glycol, or an aliphatic-hydrocarbon based heat transfer fluid. This invention also includes a method of making nanofluids. No surfactant is used to suspend the pyrogenic nanoparticles in glycols.
