Benchmark data. Information collected from industry sources to determine how other firms (especially the best in class ones) achieve their high levels of performance.

Power profiling and auditing consumption systems and methods

Systems and methods for estimating power consumption in a network of computing devices are described. Operational information of a target server is periodically received and compared to benchmark data of a model of the target server. The operational information comprises performance data of the target server during a predefined time interval. Power consumption of the target server is estimated using the performance and benchmark data. The benchmark data is recalibrated if an error in the estimated power consumption is detected. An agent installed on the target server for collecting performance data is described. The target server can be a virtualized server, in which case, the agent acquires at least some of the performance data from a hypervisor of a physical server that hosts the target server.

Method for detecting refrigerant leakage of air conditioning system and air conditioning system

The invention discloses a method for detecting refrigerant leakage of an air conditioning system and the air conditioning system. The method comprises the steps of: S10, collecting the state parameters of the air conditioning system when the external environment temperature is T in an operating process of the air conditioning system and storing the collected data at the temperature for the first time as reference data; S20, in the operating process of the air conditioning system, when the external environment temperature reaches T again, collecting the state parameters of the air conditioning system again; S30, comparing the collected data with the reference data and calculating deviation therebetween; and S40, when the deviation exceeds a predetermined value, judging the condition of refrigerant leakage. When the method disclosed by the invention is used for detecting refrigerant leakage, the detection result is not affected by an actual installing condition; the influence on the environment temperature can be eliminated, so that the extent of refrigerant deficiency in the air conditioning system can be accurately judged, and the detection result is more reliable. The invention further discloses the air conditioning system.
