Abstract:
1. A method of providing cooling by a cooling system to a computer data center, comprising: providing a plurality of air-and-water radiators and one or more chillers, the chillers each having a first side in fluid communication with a chilled water loop and a second side in communication with a condenser water loop, where the plurality of air-and-water radiators are arranged as a grid of x rows and y columns, and each of the air-and-water radiators comprises a fin-and-tube heat exchanger and a fan mounted to circulate an airflow over the fin-and-tube heat exchanger; circulating cooled supply water through a common supply header to a plurality of cooling coils positioned in airflow communication with a plurality of computers in the computer data center, the cooling coils receiving heat from the plurality of computers to provide heated water; circulating the heated water from the plurality of coiling coils in the computer data center through a common return header as return water; dividing the return water from the computer data center into a first portion and a second portion; circulating the first portion of return water coming from the computer data center to a first subset of the air-and-water radiators and through the condenser water loop; circulating the second portion of the return water from the computer data center to a second subset of the air-and-water radiators and through the chilled water loop, each of the first and second subsets of radiators comprising one or more rows or one or more columns of the plurality of air-and-water radiators in the grid; and circulating the first portion and the second portion of the return water to the computer data center as the cooled supply water through the common supply header.
