From the author: Applying airside and waterside economizer to data center projects requires additional consideration to fulfill the unique design criteria that is not common to other commercial building types. Waterside economizer design considerations include proper equipment sizing, cooling tower freeze protection, pump design for parallel and series configuration, and control strategies for system stability. Airside economizer design considerations include humidification, particulate contamination, gaseous contamination, fire prevention, smoke detection, supply and return air balancing.

From the author: This article analyzes room air distribution and describes a design chart that makes it possible to evaluate variables such as air quality, air speed and draft rate (DR), temperature gradient ([PD.sub.grad]), mean radiant temperature, and radiant temperature asymmetry ([PD.sub.rad]) as a function of flow rate and temperature difference in the supply system. Five different air distribution systems are analyzed: mixing ventilation from a wall-mounted diffuser, mixing ventilation from a ceiling-mounted diffuser, mixing ventilation from a ceiling-mounted diffuser with swirling flow, displacement ventilation from a wall-mounted low-velocity diffuser, and a low-impulse system based on a textile terminal in the ceiling. The procedure to some extent can be based on flow elements, but especially full-scale experiments and computational fluid dynamics predictions have been used for the development of the design charts described herein.

From the author: In the case of run-around loop systems there are different strategies for capacity control of the liquid flow to obtain optimal operation. Common alternatives are constant flow with variable temperature by means of a shunt group and variable flow by means of two-way valve. A more energy efficient way is direct flow control of a variable speed pump. In direct flow control a much smaller pump power is used compared to valve control. Shunt groups, in particular, result in pump power that is constant and unaffected by the real demand. Calculations based on measurements on a run-around loop system with direct flow control during three months show that the pump power after optimizing the flow can be reduced by 80 %.
