Air Induction System (AIS) OptimizationWei, Cheng January 2016 (has links)
Air intake system (AIS) plays an important role on affecting the performance of the engine and the vehicle. The design and optimization of the structures and materials of AIS contributes to producing a quality reliable system, reducing noise, cost and weight at the same time, which are significant to improve the performance of engine and vehicle. Fresh air hoses/pipes are intended to transport, in air cleaner purified, air from the air cleaner to the throttle fitted on the inlet manifold or to the compressor fitted to the exhaust manifold. Air cleaner box is responsible for filtering out the dust and impurities in the air. The charge air pipes are intended to transport purified compressed air from the compressor to the charge air cooler and then to the throttle fitted on the inlet pipe. For the air cleaner box optimization, through the benchmarking and the innovation ideas from the daily life, two alternative optimized designs were introduced to reduce the cost and weight. The first is four clips connectors and the other is spring clamps. For the hose clamps, another innovation design was introduced to replace the previous hose clamps, which is called friction connector on the inner side of the bellow hose, the outer side of the air cleaner box lid and the clean side duct. For the material of the charge air ducts, TPEE was selected to replace the previous EACM rubber hoses. Further tests and prototypes should be conducted and produced to verify the effect of the optimization.

An experimental and modelling study of fires in ventilated passages.Comitis, Spiros, Costas. January 1994 (has links)
A thesis submitted to the Faculty of Engineering, University of
the Witwatersrand, Johannesburg, in fulfillment of the
requirements for the degree of Doctor of Philosophy. / A theoretical and experimental treatment of fire processes in
fuel-Lined, ventilated passages is presented. Initially a
radially well mixed axial flow condition is considered.
Experiments are first performed in non-stratified flow
conditions where fire propagation and gas temperature histories
are acquired from liquid and solid fuelled fires. Theory and
experiment;display transient fire propagation for typical duct
fire scenarios where initial fuel mass Loading is constant with
respect to duct length. ( Abbreviation abstract ) / AC2017

Klimatizace kancelářských prostor / Air-conditioning of office roomsŠmejdová, Jaroslava January 2013 (has links)
Diploma thesis is focused on the design and dimensioning of the central air-condition system of the offices in two-story building. The thesis consists of a theoretical part which deals with air- condition systems, and computation and design part. The computation part is comprised of calculation of quantity of ventilation air, calculation of heat losses and heat gains and psychrometric evaluation of operation during summer and winter. Design part consists of design and dimensioning of air-distriutions and air ducts and consist of design of air-conditioner and machine room. There are specification of materials and drawing documentation in the end of thesis.

Čištění vzduchotechnických systémů a dosažitelné energetické úspory / Cleaning of ventilation systems and potential energy savingsLapáček, Milan January 2015 (has links)
The main aim of this thesis is to explore fouling of air ducts and its influence on energy consumption of HVAC systems. The first part focuses on typical parts that create the IAQ in buildings and on evaluating energy consumption of air transportation. The following section deals with the theories of fluid flow, flow regimes and pressure losses that are created as a side effect. The thesis outlines possible methods of assessing the impact of pollution with an emphasis on pressure losses and their influence on the fan power consumption. The actual experimental measurement, conducted in a selected industrial plant, is focused on an influence of cleanness of textile diffuser on HVAC device power consumption. For the further research of this process, measuring equipment with suitable measurement method is designed and constructed.

Klimatizace kanceláří / Air-conditioning of office roomsTaclík, Jakub January 2017 (has links)
The aim of this diploma thesis is to design the air conditioning system for one floor of the offices. The thesis is divided into theoretical, computational and design part. The computational part consists in determining the amount of ventilation air, calculation of heat losses, heat gains and psychrometric calculations for summer and winter season. Based on the calculated values, air ducts, end-points and air-conditioning units are designed. The diploma thesis is supplemented with a list of materials and drawing documentation.
