Abstract:
1. An efficiency-optimized air handling system, comprising: a blower having an inlet and an outlet; a switched reluctance electric motor operationally connected to the blower; an electronic controller operationally connected to the switched reluctance electric motor; and a sensor array operationally connected to the electronic controller; wherein the sensor array includes sensors for measuring one or more parameters from the set including blower outlet air flow, dissolved oxygen, blower outlet air pressure, blower outlet air temperature, blower inlet air pressure, blower inlet air relative humidity, blower inlet air temperature, blower speed, motor voltage, and motor amperage; wherein the electronic controller uses data from the sensor array to calculate an optimal motor speed for providing a desired air flow with minimized power consumption; wherein the electronic controller calculates the desired air flow according to the equation where SCFM represents the desired air flow from the blower outlet, ICFM represents a calculated rate of air volume through the blower inlet, P 1 represents blower inlet pressure, P std represents 14.7 PSIA, T 1 represents blower inlet air temperature, T std represents 528 Rankine, ω std represents standard humidity ratio, ω 1 represents blower inlet air humidity ratio, MW 1 represents the specific gravity of the gas flowing through the blower and MW std is the molecular weight of air at standard temperature and pressure.
