Abstract:
Constant speed fan exhaust systems are the most popular exhaust system in laboratory buildings since they satisfy building architectural requirement, and have low initial costs with reliable performance. The constant speed fan exhaust system maintains constant stack exit velocity to prevent toxic exhaust air downwash back to occupied areas near the building or on the roof top. To achieve constant velocity when the exhaust airflow is less than the design value, makeup air is introduced to the system at the inlet of the exhaust fan. Since the laboratory exhaust airflow is often significantly less than the design airflow, exhaust fans consume significantly more energy than is necessary. Multi-stack and Variable frequency drive techniques can reduce both the make-up airflow rate and fan energy in the constant speed fan exhaust system retrofit. This paper introduces the application principles, describes the optimal methods of stack sizing, and presents an example. The application example showed that the average annual fan power is 50% of the design fan power for a two-stack system, and 47% for a three-stack system.

Abstract:
Hus byggs idag allt tätare för att möta högre miljökrav, ställda av både konsumenter och politiker. När hus byggs täta minskar luftläckaget genom klimatskalet. Tack vare det sänks energiåtgången då nästan all luft styrs genom en värmeväxlare. Tätheten i de nya husen har lett till att utsugande köksfläktar inte fungerar som de ska, beroende på att de behöver mycket luft. I detta projekt utvecklades ett utsugande köksfläktsystem för passivhus, de allra tätaste husen på marknaden. Resultatet blev en utsugande köksfläkt som hela tiden tillförs luft utifrån huset. Tilluften sugs in i huset med hjälp av det undertryck som köksfläkten skapar, luften sprutas in i kåpan och sugs sedan ut ihop med matoset. För att hålla nere energiförbrukningen användes en svag köksfläkt. För att hjälpa fläkten att fånga upp matoset är fläktkåpan utformad för att utnyttja ejektorverkan och coandaeffekten. Under projektet utvecklades även en värmeväxlare som tar tillvara på värmen i frånluften.
Today houses are built more airtight to meet higher environmental standards, initiated by both consumers and politicians. When houses are built airtight it reduces air leakage through the building, which gives reduced energy consumption since almost all air is guided throw a heat exchanger. Since the new houses are very airtight it has caused extractor hoods to work improperly, because they need a lot of air. In this project a extractor hood system has been developed for passive houses, which are the most airtight houses on the market. The result was an extractor hood which is constantly getting air from outside the house. The air from outside is sucked into the house because of the vacuum created by the extractor hood, the air is injected into the hood and then sucked out together with the cooking odors. In order to minimize the energy consumption a weak extractor fan was used. To help the fan capture the cooking fumes, the hood is designed to use ejector- and coandaeffect. During the project a heat exchanger was also developed, which transfer the heat from the cooking odors to the air from the outside.

Abstract:
Multiple fans are sometimes used in an array configuration to cool various types of electronic equipment. In addition to adding another noise source, using two fans with closely spaced blade passage frequencies (BPF) can create an annoying beat frequency. A two fan array with each fan having a different BPF was considered. The fans were theoretically modeled at the BPF and first harmonics. Each fan has two acoustic paths to the far field. Thus, each fan was modeled as a two source array. The first control configuration consisted of one control filter using six control sources and six error sensors in a fully coupled control system designed to control both fans simultaneously. The second configuration used two independent controllers with three control sources and three error sensors, one controller per fan. Experimentally, the averaged narrow band reduction of the BPFs and the second harmonic of the two independent controllers were 15.6 and 7.4 dB respectively, compared to a reduction of 14.4 and 5.7 dB at the two frequencies using a single control loop. The results suggest that independent controllers perform better than the single control loop for the fan array studied. Optimization of active noise control systems has increased performance but sometimes with decreased robustness. Two control source configurations for the sound power reduction of a simple source were analyzed by modeling the control systems. The two control source configurations were four symmetric control sources surrounding the noise source and an optimized linear array of four control sources. Simulation results show the linear array control source configuration is more sensitive to microphone placement errors, with a 20-33 dB reduction in attenuation for a microphone placement error of 2 mm compared to a 0.8 dB drop in attenuation for the symmetric case. The linear array configuration was found to be more sensitive to the microphone placement errors compared to the symmetric configuration. A 2.5 mm change in one microphone position causes an average of 6 dB loss in attenuation for the linear array configuration compared to a 0.6 dB loss for the symmetric configuration.

Abstract:
The reduction of the cumulative noise level at certification points applying to the supersonic civil aeroplane is estimated in the paper. The reduction is obtained by using an programmed thrust management with Programmed Lapse Rate based on the variation of engine power setting at take-off and approach. The use of proposed programmed reduced noise thrust management requires a change of the conventional noise certification procedures as well as further implementation as fully automated system (Variable Noise Reduction System) into aircraft/engine control system. The main engine noise sources such as the fan and exhaust jet are taken into account in the estimation. It is shown that the cumulative noise level using proposed programmed thrust management is lower by 10.7–12.2 EPNdB than using the conventional engine thrust control as currently applied to subsonic jet aeroplanes at take-off and approach.

Abstract:
Fans are main components e.g. in heating, ventilating and air conditioning systems for vehicles or buildings, cooling units of engines and electronic circuits, and household appliances such as kitchen exhaust hoods or vacuum cleaners. End-users increasingly demand a high sound quality of their system or device. The overall objective of a recent research project at the University of Siegen is a multidimensional assessment of fan sound quality. In a first step an advanced novel semantic differential for the assessment of fan-related sounds is established with the aid of carefully designed jury tests. Eventually, this semantic differential is employed for sound quality jury tests of fans in kitchen exhaust hoods, heat pumps and air purifiers as a first case. Finally, a prediction model is suggested, which relates the outcome from the jury tests to objective metrics. A principal component analysis is carried out and yields five main assessment criteria with 23 relevant adjective scales. The results show that the perceived sound quality of fan systems is mainly determined by the loudness and tonality of the sound. The spectral content (represented by the sharpness) as well as the time structure (represented by the roughness) have no significant impact on perceived sound quality of the fan systems investigated.

Abstract:
The present paper aims to develop/investigate an innovative approach for affordable houses for the medium income families, forming the major category of the Egyptian society using Design-Builder simulation and emphasizing the mechanical HVAC systems and their impact on energy consumption. Design-Builder ( a simulation user-friendly interface) for Energy-Plus (an energy simulation engine for energy modeling in buildings, heating, cooling, lighting, ventilating and other energy flows) is utilized to create a “virtual environment” in which the HVAC system effect is studied. Extensive field surveys are made to collect data regarding occupancy behavior, light and equipment schedules and other mechanical systems usage in such application. The majority of surveys indicated that split system (heat pumps) + mechanical ventilation (exhaust fan for bathroom and kitchen) are most common in the Egyptian society. The subject facility is located in Cairo, Egypt. The layout of this building/house has been developed by research architects in the Housing & Building National Research Centre HRBC taking into their consideration the medium income citizens, [1] needs and limited budget, the energy efficiency concepts as well as the previous work carried in the field of sustainable architecture. The individual buildings are formed of three floors containing twelve 100 m2 apartments. Each apartment consists of three bedrooms, a bathroom, a kitchen and a lounge.

Abstract:
A multi-stack exhaust system has been developed for use in laboratory buildings. The multi-stack system activates different stacks and uses a variable speed drive (VSD) to change the fan speed when the laboratory exhaust airflow changes. This system satisfies safety requirements and uses less fan power than a conventional system. The typical fan power savings is 40% or higher, depending on the flow usage profile and the exhaust system duct design characteristics. This paper presents the system models and optimization procedures for the design of a multi-stack system.

Abstract:
The predicted potential performance of the Prop-Fan offers a major improvement in the energy efficiency of future, short-range to medium-range transports. This paper describes the approach taken in designing an optimum Prop-Fan propulsion system. Trade-offs in the configuration(s) and performance are discussed, as are the important aspects of integrating the propeller, gearbox, engine, inlet, exhaust, and nacelle. Realizing the impressive potential fuel savings of the Prop-Fan will require very careful engine/airframe integration. Design options that will be compared are: a single-rotation versus counter-rotation arrangement, a tractor versus pusher installation, and wing versus fuselage mounting. In summary, the performance of turbofan powered and Prop-Fan powered, short-haul transports will be compared in detail by using fuel burn, operating costs, and noise as criteria.

A novel airflow architecture for a networking chassis will be described in this work. This chassis is a pull system with two sets of four fans located in series at its exhaust. Each set of four fans is a field replaceable unit (FRU). The unique feature of this chassis is that one set of fans, called the rear fan FRU, is replaceable from the rear side of the chassis and the other set of fans, called the front fan FRU, is replaceable from the front side of the chassis. Computational fluid dynamics simulations and measurement data show this chassis is capable of providing up to 78% – 79% of its maximum cooling capacity when one fan FRU is removed from the chassis, and up to 62% – 67% of its maximum cooling capacity when one fan FRU has failed.

Abstract:
Abstract In this work a new exhaust air system for rotary screw compressors with integrated refrigeration dryers has been developed. The new system unites both, the exhaust air flow out of the compressor and out of the refrigeration drier and in such a way the overall exhaust air and hence the overall heat are exhausted through one single air duct. For the development of the system, the ASD 50 T SFC compressor system from KAESER Kompressoren SE [1] was used. Because of the slight overpressure in the exhaust air duct due to the cooling radial fan in the compressor, a jet pump was designed and placed into the main exhaust air duct to reduce the static pressure in the main duct. In such a way, after the jet pump the exhaust air of the refrigeration drier is sucked into the main exhaust air duct through an intake fitting. The nozzle and the intake fitting of the exhaust air duct were first designed by using the commercial CFD solver CFX from ANSYS. The nozzle length, angle and diameter were varied to determine the best geometry. In order to validate the components designed by CFD simulations, three of the designs were manufactured and measured in the compressor laboratory at Coburg University. Therefor heat and velocity measurements in the exhaust air ducts have been done. Also the flow of the exhaust air was visualized using smoke and laser sheets. The simulation and experimental results are shown in detail in this work.

Abstract:
Lignite is a domestic strategic reserve of low rank coals in many countries for its abundant resource and competitive price. Combustion for power generation is still an important approach to its utilization. However, the high moisture content always results in low efficiencies of lignite-direct-fired power plants. Lignite pre-drying is thus proposed as an effective method to improve the energy efficiency. The present work focuses on the flue gas pre-dried lignite-fired power system (FPLPS), which is integrated with fan mill pulverizing system and waste heat recovery. The thermo-economic analysis model was developed to predict its energy saving potential at design conditions. The pre-drying upgrade factor was defined to express the coupling of pre-drying system with boiler system and the efficiency improvement effect. The energy saving potential of the FPLPS, when applied in a 600 MW supercritical power unit, was determined to be 1.48 %-pts. It was concluded that the improvement of boiler efficiency mainly resulted from the lowered boiler exhaust temperature after firing pre-dried low moisture content lignite and the lowered dryer exhaust gas temperature after pre-heating the boiler air supply.
