| Sub-metering system loads is the first step in an effective energy management program. To pinpoint inefficient energy usage, you must measure the energy used by smaller sub-systems. Energy models allow accurate prediction of energy usage. A refrigeration load's energy consumption has a direct correlation to ambient temperature. As the outside temperature rises, energy consumption also rises. When actual consumption is higher than the model's prediction, there is an immediate alarm, and corrective action can be taken before outsized energy bills appear. Benchmarks compare each load to historical performance and to the performance of comparable systems across your entire enterprise. Through benchmarking, you can rank performance against same-type systems in a single facility or in the entire PowerFocus database. Temperature is normalized to compensate for regional temperature variances. Energy profiling provides a near real-time overview of energy consumption for an entire facility or for each individual load based on user-defined date and load parameters. PowerFocus reports allow customers to customize information received about their system performance. Three types of reports are available:Exception reports are used to determine if a system's energy consumption has moved away from its model.Store reports are a standard monthly store report showing overall power usage and the energy profile of each loadChain reports compare all loads across multiple facilities ranking loads from best to worst by percentile. Corrective Action
PowerFocus eliminates the guesswork of trying to identify the most inefficient systems in your enterprise. Reports can be sent directly to service and maintenance contractors, or you can contract with Danfoss service engineers to perform the maintenance necessary to restore optimum system performance. Either way, you now have precise performance reports pinpointing how and where energy usage exceeds optimal performance, making it easier for you to reduce operating costs and improve profitability. |
