Title: An Innovative Method for Dynamic Characterization of Fan FilterUnit Operation.

Abstract

Fan filter units (FFU) are widely used to deliver re-circulated air while providing filtration control of particle concentration in controlled environments such as cleanrooms, minienvironments, and operating rooms in hospitals. The objective of this paper is to document an innovative method for characterizing operation and control of an individual fan filter unit within its operable conditions. Built upon the draft laboratory method previously published [1] , this paper presents an updated method including a testing procedure to characterize dynamic operation of fan filter units, i.e., steady-state operation conditions determined by varied control schemes, airflow rates, and pressure differential across the units. The parameters for dynamic characterization include total electric power demand, total pressure efficiency, airflow rate, pressure differential across fan filter units, and airflow uniformity.

  • The number of steam generator gas path retrofit projects is increasing dramatically as utilities strive to meet air quality control (AQC) requirements. A unique approach of meeting these requirements utilizes the existing precipitators, breeching, and ID fans operating at reduced flow with a new precipitator and one ID fan added in parallel to handle the remaining gas flow. This paper presents the design considerations necessary to operate with three ID fans in parallel legs with unequal flows and pressure drops. It also addresses the sizing of the new ID fan, furnace draft control system design, fan tripping schemes and economicmore » considerations. 3 refs.« less
  • The use of communicating direct digital controls (DDC) with distributed intelligence offers new opportunities for energy conservation while maintaining occupant comfort in commercial buildings. Integrating control within a single DDC panel improves performance. Integrating control by communications between multiple controllers can further enhance system operation. One example is a DDC static pressure reset strategy for supply fan operation in variable air volume (VAV) supply air distribution systems. This strategy integrates the requirements of the VAV terminal units serving the building zones to minimize fan energy use. This article describes terminal unit operation, supply fan control, concurrent polling, operational data andmore » power savings.« less
  • As part of an energy conservation program recently implemented by the Bell System, fans in many telephone equipment buildings now operate only when necessary to bring the temperature within allowable limits, rather than continuously.In the study presented, the effects of fan operation on indoor-outdoor dust relationships were monitored at 2 representative telephone offices. The indoor dust concentrations typically increased when the fans were off. The results indicate that this increase was due to loss of constant filtration, but not due to loss of building pressurization. An expression is derived for the relative dust increase when the building fans are switchedmore » off. Among other factors, the relative increase is directly proportional to the efficiency of the building filters and to the rate at which air is recirculated through them.« less
  • We investigate the linear dispersion and other properties of the Darwin Direct Implicit Particle-in-cell (DADIPIC) method in order to deduce guidelines for its use in the simulation of long time-scale, kinetic phenomena in plasmas. The Darwin part of this algorithm eliminates the Courant constraint for light propagation across a grid cell in a time step and divides the field solution into several elliptic equations. The direct implicit method is only applied to the electrostatic field relieving the need to resolve plasma oscillations. Linear theory and simulations verifying the theory are used to generate the desired guidelines as well as showmore » the utility of DADIPIC for a wide range of low frequency, electromagnetic phenomena. We find that separation of the fields has made the task of predicting algorithm behavior easier and produced a robust method without restrictive constraints. 20 refs., 11 figs., 3 tabs.« less
  • Two spherical cavity expansion experiments were performed with SiC-N to provide high-strain rate data for developing ceramic armor penetration models. Here, an explosive charge is detonated within a cavity machined in the ceramic, generating a pulse that moves radially outward. The particle velocity at multiple radial locations from the charge, including at the charge radii, was measured and the fractured ceramic was recovered for posttest evaluation. From the particle velocity histories we derived displacement, radial strain and circumferential strain histories. In the recovered samples we observed the regions where comminution, radial cracking and circumferential cracking occurred. The elastic properties ofmore » initial undamaged SiC-N and shocked damaged material were measured using a resonant ultrasound spectroscopy (RUS). Comparison of these measurements illustrated the posttest condition of the SiC-N material. Hot isostatic pressing of ''as is'' SiC-N material demonstrated a significant increase in the quality factor. The same procedure applied to SiC-N damaged in spherical cavity experiments resulted in a significant recovery of the elastic properties.« less
