I am applying for financial aid because I currently lack the financial resources necessary to pursue my educational goals. As someone from a low-income background, my family and I face significant financial constraints that make it challenging to afford the cost of tuition, books, and other educational expenses. Despite our best efforts to save and plan, the rising costs of higher education remain beyond our means.Education is incredibly important to me, not only for personal growth but also as a means to break the cycle of poverty and contribute positively to society. I am determined to obtain a degree in [Your Field of Study], which I believe will equip me with the skills and knowledge needed to achieve my career aspirations and support my family in the future. Without financial aid, however, these aspirations might remain unattainable due to the substantial financial barriers.Additionally, working part-time while studying full-time is not a viable option for me, as it would significantly impact my academic performance and hinder my ability to fully engage with my studies. Receiving financial aid would alleviate the financial burden and allow me to focus on my education, participate in extracurricular activities, and take advantage of opportunities that will enhance my learning experience and professional development.Moreover, I am committed to giving back to my community once I have completed my education. By obtaining a degree, I will be in a better position to contribute to initiatives and projects aimed at improving the socio-economic conditions of underserved communities. This sense of responsibility and desire to help others further motivates my pursuit of higher education.I am applying for financial aid because I currently lack the financial resources necessary to pursue my educational goals.

Design a Fan Coil System for the Energy Systems Laboratory
What is a Fan Coil System ?
Energy Systems Laboratory Windows Ceiling Floor Inner Wall Outer Wall
Orientation of the Laboratory North
Design Requirements Design an air conditioning system for the summer conditions that would provide thermal comfort according to ASHRAE 55 standards( ASHRAE: American Society of Heating, Refrigerating ) The air conditioning system is based on the fan-coil technology.

Design Variables You are required to determine the number of air vents their positions the air flow rate from the vents the air temperature coming out from the vents the air humidity level You are also required to determine the required water mass flow rate and temperature into the fan coils the design of the heat exchanger (liquid – to – moist air)
Boundary Conditions Outer wall is faced to solar radiation. Outside air temperature Tair = 32 deg C. Room floor is partially subjected to solar radiation as well. All the other walls can be considered as adiabatic. Outer wall thickness and thermal properties can be estimated.
Basic Methodology 1) Start with basic thermodynamic and thermal analysis to decide on the number of vents, air flow rate and its temperature. 2) Using your initial estimates from above carry out an Ansys Icepack analysis for a more detailed view of the temperature and flow conditions inside the room. If thermal comfort conditions are met then go to designing the fan coil system. Otherwise, rerun the Icepack analysis by changing the design parameters. 3) Build a Simscape model of the room and the fan coil system as well. Find the required heat exchanger design for the fan coil system.
Step 2) Icepack Model Decide on the number of vents, their positions and air flow rate through the vents, air temperatures based on Icepack results. Windows Ceiling Floor Inner Wall Outer Wall
Alternative method for Step 2) You may also start with Simscape by dividing the room into sub-regions and having a single fan coil system for each region. Once the main design parameters are decided there, you can move on to Icepack analysis for a more detailed analysis of thermal conditions inside the room. Windows Ceiling Floor Inner Wall Outer Wall
Step 3) Use a moist air – to – liquid water heat exchanger for each fan coil and decide on its design parameters
Step 3) Check existing Simscape models to design your own model.
