Analysis of Air Conditioning System used in Automobileijtsrd
Air conditioning has great importance in many areas of life. Especially it is crucial in transportation sector. Many people spend long time in an automotive cabin during business, travel, shopping, etc., every day. The aim of this study is to analyze the performance of a bus shell by considering identifying practical solutions in order to reduce the impact of air conditioning on bus, consumption and, therefore, on air pollution. The analysis is carried considering several parameters, including passenger capacity, local climatic conditions, fuel consumptions, and latitude and longitude of starting destination of the places. For the analysis, a bus with passenger capacity of 60 people is selected and then its heat load capacity will be determined by considering different conditions like seasons and various loads. The influence of the refrigerant decrease and the change of the air temperature which gets to exchangers on the refrigeration efficiency of the system to be analyzed. Also, its effectiveness and the power required to drive the compressor will be analyzed. The entire model, its analysis and results are discussed in the below work. Dr. S. Sreenatha Reddy | P.

The present research is due to study the performance of
engine-propeller cells to be used in the design of a Micro
Air Vehicle (MAV). MAV design conditions: weight less than 200gr, maximum size 30cm, to fly a distance of 200m, and to be able to carry a camera and chemical sensors.One of the goals of the study is to use commercial parts (engines and propellers) in order to reduce manufacturing cost. The experiments are made in a subsonic open-circuit wind tunnel. The results are the aerodynamic drag coefficient of the propeller-engine cell (engine off), the static thrust test realized with engine on and tunnel off, at different RPM and the dynamic thrust test with engine and tunnel on, at different
RPM and different tunnel flow velocity.
This presentation was given at the end of the Spring 2016 semester for the class at Georgia Tech AE 4802 Digital Design and Manufacturing. The presentation encompassed the Hyperloop concept and built upon preliminary analysis done by the GT Hyperloop Team
Learn how CFD simulation can help engineers optimize ventilation systems for improved air quality, worker comfort, and energy efficiency in manufacturing units. Here we discuss a case study comparing the effectiveness of turbine and centrifugal upblast ventilators and highlights the benefits of using CFD analysis services to make informed decisions about building design.
We discuss engineering and scientific computing in the Cloud. Users today have three major choices of computing: workstations, servers, and cloud. We compare benefits and challenges of each, and present a solution: the online UberCloud community, experiment, and marketplace for engineers and scientists to discover, try, and buy compute power on demand, in the cloud. Our approach of application containerization and tight software/hardware integration removes many of the known cloud roadblocks.

2. Description
Hyperloop represents the future of high speed transit. This
is the first endeavor to invent a transportation system that
is safer, cheaper, faster and more energy efficient than
cars, planes, boats and trains. We have been working
diligently to design a half-scale pod for the the SpaceX
Hyperloop Competition. SpaceX awarded HyperXite with a
Pod Technical Excellence Award, ranking the pod 5th best
pod design in the world, 1st in air based levitation, and 1st
in California.
Responsibilities
Lead Compressed Air Systems Engineer- To design a
high pressure air system that will provide constant and
correct air properties for levitation, suspension, and
braking.
Lead Vacuum Engineer- Design a vacuum chamber to
test all instrumentation and materials for vacuum
compatibility.

3. Compressed Air System
Project Link: HyperXite.com
Description
The purpose of the Compressed Air System is to
pneumatically actuate the suspension and
magnetic braking systems, while delivering a high
flow of air to the levitation system. The system
begins with two 3,500 psi composite
overwrapped pressure vessels (COPV) with two
pressure regulators in series to deliver 80 psi to
the system. There are ten pressure safety valves
to prevent overpressure in the system. A
combination of normally open and normally
closed 24VDC solenoid valves direct the flow to
the appropriate systems. An electronic pressure
regulator provides 0.1 psi accuracy to actuate the
magnetic braking system. There are eight
pressure transducers that will output pressure
signals to the programmable logic controller. All
together, the system is one fault tolerant to
provide redundancy for safety.

5. Fluids Testing
Project Link: HyperXite.com
Thermal Testing:
Due to the Joule-Thomson Effect, as air leaves the
COPV it experiences a temperature drop and
becomes very cold (approximately -3 Celsius). We
needed to test the lower limits of the temperature
change so that appropriate instrumentation could
be selected. We used a thermocouple, flow
controller, and a pressure regulator to simulate
operating conditions.
Flow Rate and Pressure Testing:
Our levitation system mimics the design of a
hovercraft, which operates under high flow rates.
The necessity for high flow rates drove us to test
multiple valves and regulators for optimization. The
chart on the left describes the output flow rate of
the electronic pressure regulator as a function of
pressure. We used pressure regulators, valves, and
pressure transducers to simulate operating
conditions. These tests were crucial to validating
the success of our compressed air system.
6. Vacuum Compatibility Testing
Project Link: HyperXite.com
Vacuum Compatibility Testing is necessary to
verify our instrumentation works correctly in
vacuum environments. I designed electrical
and air feedthroughs to allow us to test inside
a vacuum chamber. I tested solenoid valves,
electronic pressure regulators, and pressure
transducers for long durations under vacuum
to simulate the pod in the vacuum tube.
Thermal properties were monitored by a
temperature gun.
I partnered with the American Vacuum
Society to host an all-day vacuum course for
the team with a focus on Hyperloop
applications. We were able to get insight into
the aerospace industry and what
considerations have to be made for selecting
lubricants, electrical devices, and materials.
