Cool Air Commodity UFAD Systems In High-Density Trading Floors

Here, the pressures on the occupants are exceeded only by the weight of the cooling loads. However, underfloor air proves to be a good fit for an unusual setting. Take stock of the requirements, then look for designs that can pay dividends.
