摘要:
A ventilation system includes a ventilation tile. The ventilation tile has a substantially circular opening to allow air to flow through the ventilation tile and a collapsible damper operable to collapse and expand to alter the size of the substantially circular opening in the ventilation tile and thereby variably restrict air flow through the substantially circular opening.

In a method for determining a state of an apparatus, detected temperatures are received from a plurality of sensors and are compared to at least one preset condition. The state of the apparatus is determined based upon the comparison.

A system for managing a structure having cooling fluid configured to flow around and absorb heat from components contained in the structure includes a plurality of separate cooling mechanisms configured to absorb heat from the cooling fluid. At least two of the plurality of separate cooling mechanisms have at least one different level of a metric with respect to each other. The system also includes a controller configured to implement the plurality of separate cooling mechanisms in a staged manner to remove heat from the cooling fluid. The staged manner includes implementing the cooling mechanism having a relatively lower at least one metric level first and implementing a cooling mechanism having a relatively higher at least one metric level last, to cool the structure.
摘要:
A method of maximizing server utilization within a datacenter comprising collocating a number of workloads to a subset of a number of physical servers within a datacenter, adjusting access to resources by critical and non-critical workloads, isolating a number of critical workloads that share resources to the subset of resource instances, and controlling resource utilization of the collocated workloads. A system for collocating workloads in a datacenter, the system comprising a number of servers communicatively coupled to each other and a collocation module that receives information from each server and decides whether to leave a workload running on one of any of the servers on that server, or migrate a workload running on one of the number of servers to another server.

Systems and methods to condition air are disclosed. An example system includes a desiccant heat transfer device to supply conditioned air to a facility, an air intake to receive air to be conditioned via the desiccant heat transfer device, and a make-up exhaust to provide exhaust air from a heat dissipating device in the facility to provide heated air to reactivate the desiccant heat transfer device.

A method for managing a cloud using a cloud controller and a sustainability metrics manager having executable computer-readable instructions stored on a database first includes receiving a request from a cloud user to implement a new cloud service having at least one service characteristic. Once the request is received, the controller computes a prediction of a first sustainability impact based on the service characteristic for an implementation of the cloud service on a high quality of service (QoS) server operating in the cloud, and also computes a prediction of a second sustainability impact based on the service characteristic for an implementation of the cloud service on a high sustainability server operating in the cloud. The controller then presents the first and second predicted sustainability impacts to the cloud user so that the cloud user can make an informed decision with regard to the new cloud service request.
摘要:
In a method of estimating a replacement cost associated with an existing technology performed by a processor, one or more costs associated with implementing the existing technology are obtained, in which the one or more costs include an environmental cost and a utility cost associated with implementing the existing technology. In addition, an existing net benefit of continuing implementation of the existing technology based upon the obtained one or more costs are calculated.

A virtual power infrastructure for managing distribution of power to a plurality of power demanding units from a plurality of power generators includes a demand manager having logical descriptions of the power demanding units, in which the demand manager is configured to determine power load demands of the power demanding units using the logical descriptions of the power demanding units, and a capacity manager having logical descriptions of the power generators. The capacity manager is configured to determine allocation of power capacity supplied to the power generators from one or more of the power generators to meet the power load demands of the power demanding units, while satisfying one or more predetermined constraints associated with at least one of the power demanding units and the power generators.
摘要:
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.
摘要:
A system for managing distribution of a cooling medium includes a sensor configured to detect a condition, a first agent configured to receive the detected condition and to determine whether a characteristic of the cooling medium controlled via a first actuator is to be manipulated based upon the detected condition. The system also includes a second agent configured to receive at least one of the detected condition and the flow manipulation determination of the first actuator and to determine whether a characteristic of the cooling medium controlled by a second actuator is to be manipulated based upon the at least one of the detected condition and the characteristic manipulation determination of the first actuator.
