Model-Based Approach for Optimizing a Data Center Centralized Cooling System

Date: January 2008
Type: White Paper
Rating: (0)

Overview: A steady-state model for a centralized cooling system is developed to enable proper provisioning of cooling resources in capital intensive projects as data centers. The model resolves the energy equations for a cooling tower and a centralized water-cooled chiller simultaneously. It requires inputs that are readily available to the design engineer. The model utilizes an empirical relationship for the compressor power as a function of load and temperature and gives the user an option to select a constant speed chiller or a variable speed chiller. The model results are found to match the experimental data to within an acceptable deviation.
