Download or read book HVAC Applications written by Charles Nehme and published by Charles Nehme. This book was released on with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: HVAC (Heating, Ventilation, and Air Conditioning) systems are used in many applications to provide comfort and safety to people and equipment. HVAC systems are designed to maintain indoor air quality and temperature, provide ventilation, and control humidity. They are primarily used in residential, commercial, and industrial buildings, as well as in marine applications. Residential buildings are the most common application for HVAC systems. These systems are designed to provide a comfortable living environment for people and pets, as well as maintain a healthy indoor air quality. They do this by controlling the temperature, humidity, and air quality of a home. HVAC systems are also used to provide ventilation and air filtration, as well as to reduce the risk of fire and airborne contamination. Commercial and industrial buildings also use HVAC systems to ensure a comfortable working environment. These systems are designed to control the temperature and humidity of the space, as well as provide air circulation and filtration. They are also used to maintain a safe and healthy air quality in the building. In addition to buildings, HVAC systems are also used in marine applications. These systems are designed to maintain the temperature, humidity, and air quality of ships, submarines, and other marine vessels.

Download or read book ACTIVE NOISE CONTROL USING CARBON NANOTUBE THERMOPHONES written by and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The goal of this project was to reduce the overall noise levels emitted by the HVAC components in a vehicle's cabin. More specifically, the feasibility of achieving this goal using two key technologies was investigated. The first of these technologies, Active Noise Control (ANC), is a noise attenuation technique that relies on destructive interference that "cancels" unwanted noise. Typically used in situations where physical constraints prevent passive attenuation techniques from being used, ANC is known for its high size-to-effectiveness ratio. This benefit cannot be gained without a cost however; the complexity of ANC systems is significantly higher than their passive counterparts. This is due to the signal processing and actuator designs required. These actuators often take the form of moving-coil loudspeakers which, while effective, are often bulky. Because of this they are difficult to "drop in" to an existing system. This is where the second technology comes in. Carbon Nanotube (CNT) Thermophones are solid-state speakers that operate by using rapid heat fluctuations to create sound. Called the "thermoacoustic effect," (TE) the theory of this operating principle dates to the turn of the 20th century. Useful demonstration of TE did not occur until 2008, however, when researchers first developed the first CNT thermophones. The hallmark characteristics of these transducers are their small size and flexible nature. Compared to traditional loudspeakers they have a much smaller form factor and are more versatile in terms of where they can be placed in a cramped system. The marriage of CNT transducers to ANC technology shows promise in improving the application space and ease of installation of ANC systems. Getting these two to cooperate, however, is not without challenges. A case study for this union is presented here; the application space being the ducted environment of vehicle HVAC systems.

Download or read book Theory and Applications of Aerodynamics for Ground Vehicles written by T Yomi Obidi and published by SAE International. This book was released on 2014-03-20 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to ground vehicle aerodynamics and methodically guides the reader through the various aspects of the subject. Those needing specific information or a refresher can easily jump to the material of interest. There is a particular emphasis on various vehicle types (passenger cars, trucks, trains, motorcycles, race cars, etc.). However, the book is focused on cars and trucks, which are the most common vehicles in the speed range in which the study of ground vehicle aerodynamics is beneficial. Readers will gain a fundamental understanding of the topic, which will help them design vehicles that have improved aerodynamics; this will lead to better fuel efficiency, improved performance, and increased passenger comfort. The author’s basic approach to the presentation of the material is complemented with review questions, application questions, exercises, and suggested projects at the end of most of the chapters, which helps the reader apply the information presented, either in the classroom or for self-study. Aside from offering a solid understanding of ground vehicle aerodynamics, the book also offers more thorough study of several key topics. One such topic is car-truck interaction, when one vehicle (usually the smaller one) is overtaking the other. There is a direct and instant benefit in terms of safety on the highway from understanding the forces at play when one vehicle passes the other in the same direction and sense. Chapters examine: • Drag • Noise and vehicle soiling • Wind tunnels and road/track testing • Numerical methods • Vehicle stability and control • Vehicle sectional design • Large vehicles: trucks, trailers, buses, trains • Severe service and off-road vehicles • Race cars and convertibles • Motorcycles • Concept vehicles

Download or read book Automotive Software Engineering written by Thomas Zurawka and published by SAE International. This book was released on 2016-09-18 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early seventies, the development of the automobile has been characterized by a steady increase in the deploymnet of onboard electronics systems and software. This trend continues unabated and is driven by rising end-user demands and increasingly stringent environmental requirements. Today, almost every function onboard the modern vehicle is electronically controlled or monitored. The software-based implementation of vehicle functions provides for unparalleled freedoms of concept and design. However, automobile development calls for the accommodation of contrasting prerequisites – such as higher demands on safety and reliability vs. lower cost ceilings, longer product life cycles vs. shorter development times – along with growing proliferation of model variants. Automotive Software Engineering has established its position at the center of these seemingly conflicting opposites. This book provides background basics as well as numerous suggestions, rare insights, and cases in point concerning those processes, methods, and tools that contribute to the surefooted mastery of the use of electronic systems and software in the contemporary automobile.
