System Performance Monitoring
Airclean Engineering believes there is no substitute for onsite-data collection. As part of this belief Airclean Engineering gathers its own reliable system data in the field using techniques outlined by agencies such as Air Movement and Control Agency (AMCA), American Society of Mechanical Engineers (ASME) and The International Performance Measurement and Verification Protocol (IPMVP). Our engineers are all proficient in the use of measuring devices, such as: pitot tubes, ultrasonic-flow measurements, power-data loggers, process-data loggers and many others.
Many engineering companies will use product literature, fan and pump curves, rules of thumb or best guess assumptions to estimate energy consumption. Airclean believes that this is a bad idea due to each facility's unique set of operations, equipment and system arrangement, and inaccurate manufacturers' data. Field measurements must be taken and power should be logged, in general, for at least two weeks to understand the day-to-day operation of a system. The collected measurements and power data then needs to be correlated to operating conditions that will allow annual, energy-consumption estimates to be made even with variable production rates. There are standardized protocols for M&V, but in general we prefer to develop the baseline protocol, as well as the M&V, to suit the specifics of the process.
