Abstract

A modular cooling system for data center. An airflow section forms a duct for air flow and a plurality of core units are serially attached to each other and to the airflow section. A blower unit is attached to each of the core units. A plurality of motorized dampers are provided: between each of the core units and the airflow unit, in between each two core units, and between each core unit and its corresponding blower unit. A plurality of fluid ports are attached to each of the core units. At least one of the core units is loaded with one or more equipment selected from: air filter, humidifier, dehumidifier, heat exchanger, evaporator, condenser, chiller, computer room air conditioner (CRAC), dry cooler, a cooling tower or other types of cooling equipment. A combination operation of the components on the compartment and the cooling units enables fast deployment and operation.
