Tracking electronic devices that are equipped with tracking tags and that are stored in designated locations. The position of a reading device is monitored as it traverses the designated locations of the electronic devices and is activated to interrogate the tracking tags of the electronic devices. Identification data from the tracking tags is collected to enable determining the presence and location of the electronic devices, based on the monitored position of the reading devices.
摘要:
Tracking electronic devices that are equipped with tracking tags and that are stored in designated locations. Reading devices are distributed in locations that are recorded and that correspond to the designated locations of the electronic devices. The reading devices are activated to interrogate the tracking tags. Identification data from the tracking tags is collected to enable determining the presence and location of the electronic devices, based on the recorded location of the reading devices.
摘要:
A device for reducing temperature variation in a plenum includes at least one pipe and a plurality of sumps containing a fluid operable to vary between a liquid state and a gaseous state depending upon a temperature of the fluid. The plurality of sumps are positioned at various locations within the plenum and the at least one pipe is in fluid communication with the plurality of sumps. In addition, the fluid, in the gaseous state, is caused to move through the at least one pipe and condense, thereby reducing the temperature at the location of the sump where the fluid was vaporized and thereby reducing temperature variation in the plenum.

A refrigeration system for controlling airflow around an air-cooled heat generating device having a plurality of components includes a refrigerant line split into second refrigerant lines, which are arranged in a parallel configuration with respect to each other. Evaporators are positioned along the second refrigerant lines and in the path of airflow supplied into the components or airflow exhausted from the components. The refrigeration system further includes a variable speed compressor and a controller for controlling the speed of the variable speed compressor. Furthermore, the refrigeration system includes a temperature sensor configured to transmit signals related to a detected temperature to the controller, and the controller is configured to vary the speed of the variable speed compressor based upon the detected temperature.

A refrigeration system for controlling airflow around an air-cooled heat generating device includes a variable speed compressor. The refrigeration system also includes evaporators positioned along a refrigerant line in a serial configuration with respect to each other and are positioned directly in at least one of the path of airflow supplied into the heat generating components and the path of airflow exhausted from the heat generated components. The refrigeration system further includes a controller and at least one temperature sensor. The temperature sensor is configured to transmit signals related to the detected temperature to the controller, and the controller is configured to vary the speed of the variable speed compressor based upon the signals received from the temperature sensor.
摘要:
In a method for correlating airflow delivery devices with air conditioning (AC) units having actuators for varying flow rates of air supplied by the air movers, flow rates of air supplied through the airflow delivery devices at a plurality of settings of the actuators are determined. Coefficients that relate the flow rates of air supplied by the air movers to the flow rates of air supplied through the airflow delivery devices based upon the flow rates determined at the plurality of actuator settings is calculated and the airflow delivery devices are correlated with the air movers using the calculated coefficients.
摘要:
In a method for controlling temperature using a sensor network, the sensors of the sensor network are commissioned and one of a plurality of control schemes for operating a primary actuator configured to vary temperatures of the sensors based upon energy utilization requirements of the plurality of control schemes is selected. In addition, the selected one of the plurality of control schemes is implemented to vary the temperatures detected by the sensors.

In a method for predicting an airflow rate of at least one air delivery device, a plurality of airflow rates through the at least one air delivery device at a plurality of airflow rates of at least one air moving device are received. A conditional probabilistic model is generated with the air moving device flow rates as inputs and the airflow rates through the at least one air delivery device as outputs. Moreover, the airflow rate of the at least one air delivery device is predicted from the conditional probabilistic model.
摘要:
At least one computer system receives power from a power system having a maximum power output based on a nominal power consumption of the at least one computer system. The power system is operable to detect an amount of power consumed by the at least one computer system, and compare the power consumption to a threshold based on the maximum power output of the power supply. The power system is operable to place one or more components of the at least one computer system in a lower-power state to reduce power consumption in response to the amount of power consumed by the at least one computer system exceeding the threshold.
