Marks: 100 Instructions to Student • • • • • Present the relevant references/citation at the end of the document. The project work has to be done in a group, and the number of group members should be between 3 and 5. You can refer books in the Library or use internet resources. But you should not cut and paste material from the sources you have referred. For individual assessment, each group member will present the group work and his/her contribution to the project work. The write-up of the report should follow the format and contents given in this guide. Feedback will be given in every week class sessions as required in addition to the feedback which will be given in MEC Learn for the submissions. • The marks received on the assignment will be scaled down to the actual weightage of 50%. Feedback after the final evaluation will be provided by in two weeks of the submission date. Module Learning Outcomes The following LOs are achieved by the student by completing the assignment successfully 1. Apply a logical design methodology to the solution of a thermal systems design problem and apply cost estimation techniques. 2. Use an understanding of psychometrics and its application in HVAC engineering and design to practice or observe psychrometric measurements 3. Apply understanding of thermodynamics and fluid mechanics in the design, engineering, and operation of refrigeration and cooling systems as well as efficient piping and duct systems design and associated room air distribution systems flow machines, and control systems 4. Use contemporary issues of ozone depletion and global warming hazards in thermal systems design MEC_AMO_TEM_035_04 Page 1 of 15 - Design of Thermal Systems (MECH-0009.1) — Spring-2024 - CW (Design Project) - R - QP Assignment Objective Conducting a facility study and estimating the cooling load of a lecture room or a hall within MEC that can accommodate at least 35 people. • Determine the size of different components of the air-conditioning equipment and select an • appropriate air-conditioning system for the selected facility. Determining the duct size and piping system configuration. Compare your design with the existing one. Prepare the layout drawing using AutoCAD software or other compatible software. Creating an air conditioning system with minimal ozone depletion and global warming effects. • Calculation of the air-conditioning system's initial and ongoing costs. Assignment Tasks 1. Design Parameters ✓ Temperature range: 22 to 25°C ✓ Relative Humidity: 40 to 60% Airspeed: 15 m/min Room occupancy: at least 35 people. 2. Introduction Air conditioning is a thermos-fluid science application in which the environment's weather may be adjusted for human comfort and the preservation of various materials during storage, transportation, and other processes. The project guide outlines the tasks that students must complete, as well as the marking grids and basic design specifications. Students are expected to determine a facility's cooling load, choose an acceptable type of air-conditioning system, identify duct size and layout, estimate air- conditioning system expenses, etc., as described in this guide. Task 1 Proposal Preparation The proposal should contain the following items: MEC_AMO_TEM_035_04 (10 marks) Page 2 of 15 i. Title - Design of Thermal Systems (MECH-0009.1) — Spring-2024 - CW (Design Project) - R - QP A proper title for the project has to be selected that describes the actual design which will be done in the project. ii. Background The background section gives a general overview of the project. The chosen room type, size, and orientation, as well as the underlying principles of air conditioning, types of air-conditioning systems, and so on. The introductory section can also include a literature review, the subject under inquiry, what the project is all about, the importance of the project, and so on. This section assists any technical person who is unfamiliar with the subject being investigated in understanding the project. iii. Problem Statement The problem statement contains a clear and concise statement of the problem that is going to be solved by the proposed research. iv. Objectives of the Project This section should include what the project is intended to solve specific to the selected room. The objectives should be SMART (specific, measurable, attainable, realistic, and time-bound) and include a concise statement describing the research's aim or products. The goal(s) should be stated positively (e.g., to develop, to determine, to measure, rather than broad generalities, such as, to investigate, to study). V. Methodology This section lays out the strategy for achieving the project's goals in a clear, precise, and thorough manner. The database used in the design, the method of data analysis, the processes in the design process, and the analytical, empirical, and theoretical principles employed in the design must all be addressed. vi. Schedule This section provides a timetable or the project action plan which explains each of the tasks to be carried out and the anticipated time for completion (the timeframe should consider the MEC_AMO_TEM_035_04 Page 3 of 15 - Design of Thermal Systems (MECH-0009.1) — Spring-2024 - CW (Design Project) - R - QP submission date of the project work). Use a bar chart to show the tasks to be done and the time frame to complete them. vii. Reference This section should provide a list of the sources or academic works that have been used in the proposal writing. Follow APA Reference Style. Task 2 (60 marks) i. Air conditioning system design and drawing preparation The design of the air conditioning system should address the objectives stated in the assignment objective section (selection of system components, determination of the capacities of different components, i.e., compressor, condenser, fan, dryer, expansion valve, evaporator, and blower). ii. Project Report The main topics included in the project report are more or less similar to the project proposal. However, the content of the project report is more detailed and the discussions are more realistic which is based on the investigations and findings of the study of the project work. The content of the project has to incorporate at least the topics mentioned in the objective section. Task 3 (30 marks) Presentation (individual) The student is expected to discuss the procedures, relationships, assumptions, design calculations, justifications for selecting different components of the air conditioning system. In addition, the student should highlight his/her contribution to the project work. The student is also expected to give an appropriate answer to questions asked during the presentation from any section of the project.
