Abstract
A mobile system for simulating a thermal load and airflow expected in the operation of a data center includes a thermal energy source, an impeller and impeller drive unit, an outlet port, a frame and a ground engaging member. The thermal energy source provides thermal energy to air adjacent to the thermal energy source. The impeller controls a flow rate of air adjacent to the adjacent to the thermal energy source. The outlet port outputs the flowing air. The impeller drive unit drives the impeller at a frequency based on a determined airflow at the outlet port. The frame supports the thermal energy source, the impeller, the output port and the drive unit. The ground engaging member supports the frame and enables the mobility of the system.

A mobile system for simulating a thermal and airflow load expected in operation of a data center, the system comprising:
- a thermal energy source configured to provide thermal energy to air adjacent to the thermal energy source;
- an impeller oriented substantially horizontal and configured to control a flow rate of the air adjacent to the thermal energy source such that the air adjacent to the thermal energy source flows in a vertically upward direction;
- a safety grate to protect at least one of the impeller or the thermal energy source;
- an output port positioned vertically above the impeller and oriented substantially horizontal, wherein the output port is configured to output the vertically flowing air;
- an impeller drive unit configured to drive the impeller at a rotational frequency that is varied during operation of the system based on a comparison of a predetermined airflow range and an actual airflow through the output port, wherein the actual airflow is monitored during the operation of the system by an airflow meter that is positioned either adjacent or within the output port, wherein the predetermined airflow range corresponds to the airflow load expected in the operation of the data center and a predetermined airflow tolerance;
- a frame configured to support the thermal energy source, the impeller, the output port and the drive unit;
- a collapsible duct to accommodate a variable height of the frame;
- and
- a plurality of ground engaging members supporting the frame and configured to enable mobility of the system,
- wherein the impeller drive unit is further configured to vary the rotational frequency of the impeller during the operation of the system so that the actual airflow through the output port substantially matches the predetermined airflow range so that the airflow load expected in the operation of the data center is substantially simulated.
A cart for commissioning a data center, the cart comprising:
- a duct that includes a first end and a second end;
- a duct heater configured to heat air flowing through the duct;
- a fan oriented substantially horizontal and configured to induce the flow of air through the duct, wherein the flow of air through the duct is in a vertically upward direction;
- an output port positioned vertically above the fan and oriented substantially horizontal, wherein the output port is coupled to the second end of the duct;
- a variable frequency drive (VFD) to drive the fan at a rotational frequency based on a comparison of a predetermined airflow range and an actual airflow through the output port, wherein the actual airflow is monitored by an airflow meter that is positioned either adjacent or within the output port, wherein the predetermined airflow range corresponds to an airflow load expected during the operation of the data center and a predetermined airflow tolerance;
- a frame that includes a plurality of telescoping frame members, the frame is configured to support the duct, the duct heater, the fan and the output port, wherein the plurality of telescoping frame members are coupled to the output port and the first end of the duct is coupled to at least one of the frame, the duct heater, or the fan, and wherein a vertical height of the plurality of telescoping frame members is adjustable to enable a user to vary the vertical position of the output port;
- and
- a plurality of wheels supporting the frame and configured to enable the translation of the cart to a plurality of positions within the data center,
- wherein the VFD varies the rotational frequency of the fan so that the actual airflow through the output port substantially matches the predetermined airflow range so that the airflow load expected in the operation of the data center is substantially simulated.
