Veneris School of Architecture, National Technical University of Athens, Section III, 42 Patission Av., 10682 Athens, Greece; [email protected] * Correspondence: [email protected]; Tel.: +30-210-772-3885 (ext. 3567) Received: 5 January 2018; Accepted: 13 February 2018; Published: 15 February 2018 Abstract: Wind catchers are one of the oldest cooling systems that are employed to provide sufficient natural ventilation in buildings. In this study, a laboratory scale wind catcher was equipped with a combined evaporative system. The designed assembly was comprised of a one-sided opening with an adjustable wetted pad unit and a wetted blades section. Theoretical analysis of the wind catcher was carried out and a set of experiments were organized to validate the results of the obtained models. The effect of wind speed, wind catcher height, and mode of the opening unit (open or closed) was investigated on temperature drop and velocity of the moving air through the wind catcher as well as provided sensible cooling load. The results showed that under windy conditions, inside air velocity was slightly higher when the pad was open. Vice versa, when the wind speed was zero, the closed pad resulted in an enhancement in air velocity inside the wind catcher. At wind catcher heights of 2.5 and 3.5 m and wind speeds of lower than 3 m/s, cooling loads have been approximately doubled by applying the closed-pad mode.

  • The Wind-Catcher, a Traditional Solution for a Modern Problem Narguess
    THE WIND-CATCHER, A TRADITIONAL SOLUTION FOR A MODERN PROBLEM NARGUESS KHATAMI A submission presented in partial fulfilment of the requirements of the University of Glamorgan/ Prifysgol Morgannwg for the degree of Master of Philosophy August 2009 I R11 1 Certificate of Research This is to certify that, except where specific reference is made, the work described in this thesis is the result of the candidate’s research. Neither this thesis, nor any part of it, has been presented, or is currently submitted, in candidature for any degree at any other University. Signed ……………………………………… Candidate 11/10/2009 Date …………………………………....... Signed ……………………………………… Director of Studies 11/10/2009 Date ……………………………………… II Abstract This study investigated the ability of wind-catcher as an environmentally friendly component to provide natural ventilation for indoor environments and intended to improve the overall efficiency of the existing designs of modern wind-catchers. In fact this thesis attempts to answer this question as to if it is possible to apply traditional design of wind-catchers to enhance the design of modern wind-catchers. Wind-catchers are vertical towers which are installed above buildings to catch and introduce fresh and cool air into the indoor environment and exhaust inside polluted and hot air to the outside. In order to improve overall efficacy of contemporary wind-catchers the study focuses on the effects of applying vertical louvres, which have been used in traditional systems, and horizontal louvres, which are applied in contemporary wind-catchers. The aims are therefore to compare the performance of these two types of louvres in the system. For this reason, a Computational Fluid Dynamic (CFD) model was chosen to simulate and study the air movement in and around a wind-catcher when using vertical and horizontal louvres.

  • Standard Methods for Characterizing FFU Energy Performance
    An Innovative Method for Dynamic Characterization of Fan Filter Unit Operation (Paper submitted December 21, 2006; accepted May 9, 2007, Approved July 26, 2007) Tengfang Xu Building Technologies Department Environmental Energy Technologies Division Lawrence Berkeley National Laboratory University of California, Berkeley, CA 94720-8134 One Cyclotron Road Tel: (510) 486-7810 BLDG 90R3111 Fax: (510) 486-4089 Corresponding author e-mail: [email protected] 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. Keywords Fan filter unit (FFU), cleanroom, energy efficiency, airflow uniformity, airflow rate, air pressure, test standard 1. Introduction Fan filter units are widely used to deliver re-circulated air and provide filtration control for particle concentration in controlled environments such as cleanrooms, minienvironments, and operating rooms in hospitals. For example, much of the energy in cleanrooms (and minienvironments) is consumed by 2-foot x 4-foot (61-cm x 122-cm) or 4-foot x 4-foot (122- cm x 122-cm) fan filter units that are typically located in the ceiling of controlled environments.

We have designed and developed our FFU precisely Nicotra Gebhardt FFU’s are available: so that they match the requirements in clean rooms perfectly. • as standard or customer-specific versions • for standard and customer-specific ceiling grids The “heart” of the FFU is the motor impeller unit. • for different filter and grid sizes All components, such as, for example, inlet nozzles, impellers, motors and the corresponding commutation • as top load or bottom load version units to control the motor are adapted to each other • for fluid or dry seal systems as precisely as possible – and work together in perfect • for different volume flows and pressure losses interaction in an exemplary manner. • with minimal vibration and noise emissions And another important aspect: Tailored solutions for • with a flush-mount external rotor motor the control and monitoring of the FFU networks ensure • Change in rotational speed using BUS or control ease of use. voltage • for different control systems RHP MultiEvo Simple handling: Controlling and monitoring of your FFU networks The core element of the system solutions we developed are the control centres for parameterisation and monitoring of your FFU networks on the basis of various RS485 interfaces (G-bus/Modbus RTU). We can optionally offer you three different components for actuation according to requirements: • Handheld FANCommander 100 for actuation of up to 100 FFUs. • Mini control centre FANCommander 200 for actuation of up to 200 FFUs.

  • Dispersion of Gas Pollutant in a Fan-Filter-Unit (FFU) Cleanroom
    ARTICLE IN PRESS Building and Environment 42 (2007) 1902–1912 www.elsevier.com/locate/buildenv Dispersion of gas pollutant in a fan-filter-unit (FFU) cleanroom Sheng-Chieh Chena, Chuen-Jinn Tsaia,Ã, Shou-Nan Lib, Hui-Ya Shihb aInstitute of Environmental Engineering, National Chiao Tung University, No. 75 Poai St., Hsin Chu, Taiwan, ROC bCenter for Environmental, Safety and Health Technology, Industrial Technology Research Institute (ITRI), Hsinchu, Taiwan, ROC Received 7 July 2005; received in revised form 18 October 2005; accepted 28 February 2006 Abstract Numerical simulation and experimental measurement of flow and concentration fields in a working fan-filter-unit (FFU) cleanroom have been conducted in this study. The purpose of the study is to find out the unsteady concentration distribution of a leaking gas pollutant. The standard K–e model was used for the simulation of the flow field. To obtain the gas concentration field, SF6 gas with a certain concentration was released as a simulated leaking source from a valve manifold box (VMB) for 5 or 10 min, respectively. Three Fourier transform infrared spectrometers (FTIRs) were simultaneously used to measure the spatial and temporal distributions of SF6 concentrations. The measured data were then compared with the numerical results and the agreement is seen to be quite good. From the numerical results, the pollutant hot spots, peak pollutant concentration at the end of leaking, and time taken for the concentration to reduce to near background level are obtained. r 2006 Elsevier Ltd.
