Assignment Tasks (100 Marks)
Introduction
Air conditioning system is one of the thermo-fluids science applications in which the weather condition of the environment in an enclosed space can be controlled for human comfort and preservation of different materials during storing, transporting, etc.
This project is worth 50% of the total marks of the Module. The project guide gives direction regarding the tasks that have to be accomplished by the students, marking grids, and basic design parameters. Students are expected to determine the cooling load of a specific facility below, select the appropriate type of air-conditioning system, determine duct size and layout, estimate costs of the air-conditioning system, etc.
Design Parameters
o Room purpose: University Classroom/Hall
o Temperature range: 22 to 25°C
o Average Relative Humidity of Muscat: 57%
o Average airspeed: 3-5 m/s
o The sunlit window direction is given in Table 1.
o Use cooling load temperature difference (CLTD), solar cooling load factor (SCL), and internal cooling load factor (CLF) methods for calculating the air-conditioning cooling load and sizing cooling equipment for nonresidential applications. Do the calculations for the determination of the cooling load and sizing the equipment manually.
o Consider a window size of 1.5m width by 2m height.

A student can be given a maximum of 2 chances to attend the viva in such cases. It is expected that the student attends the viva during the first chance itself unless due to extenuating circumstances. If the student does not attend the viva in spite of being given 2 chances and fails to submit valid reasons,
Design of Thermal System (MECH 0009.1) – Spring 2021 –Assignment 1– A&B – QP
MEC_AMO_TEM_035_02 Page 6 of 10
he/she will be awarded a fail in the module and this shall be counted as a case of academic integrity violation.
All cases of violation of academic integrity on the part of the student shall fall under any of the below mentioned categories:
1. Plagiarism
2. Malpractice
3. Ghost Writing
4. Collusion
5. Other cases
If the student fails a module and has a proven case of academic integrity violation in this module, the student is required to re-register the module. This is applicable to first and second offence of academic integrity violation of plagiarism type
1.1. First Offence of Academic Integrity Violation:
1.1.1. Plagiarism
a. If a student is caught first time in an act of academic integrity violation during his/her course of study in any assignment other than project work and if the type of violation is plagiarism, then the student will be allowed to re-submit the assignment once as per the period allowed for re submission However, a penalty of deduction of 25% of the marks obtained for the resubmitted work will be imposed.
b. Period of re-submission: The student will have to re-submit the work within one week (5 working days) from the date he or she is advised to re-submit.
c. Re-submission of the work beyond the allowed period of resubmission will not be accepted and the assessment will be awarded a zero mark.
d. If the re-submitted work (within the allowed period of resubmission) is also found to be plagiarized, then that assessment component will be awarded a zero mark. It shall also contribute to the total count of academic integrity violation for that student.
e. If plagiarism is detected in UG Project work (Project 1, Project Planning and Project Design and Implementation), the above clauses do not apply, and the work will be summarily rejected. In these cases the student will be awarded a fail (F) grade and is required to reregister the module.
Design of Thermal System (MECH 0009.1) – Spring 2021 –Assignment 1– A&B – QP
MEC_AMO_TEM_035_02 Page 7 of 10
1.1.2. Malpractice / Ghostwriting / Collusion

b. The student shall also receive a warning of suspension in such cases.
1.3. Third Offence of Academic Integrity Violation:

1.6. Types/Variations of cases of Plagiarism and associated actions
Type 1: In case plagiarism is detected in any component or part submission (submitted at different times) of one assessment (assignment), the deduction in marks will be applicable for the whole assessment (assignment), even if only the component or part submission alone needs to be resubmitted.
Type 2: In case plagiarism is detected in a group assessment, all students of the group will be considered as having committed an act of plagiarism irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all students.
If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and the penalty will be applied as per the policy for each student according to his / her history of violations.
Type 3: Combination of Type 1 and Type 2: In case plagiarism is detected in any component or part submission (submitted at different times) of a group assessment (assignment), the deduction in marks will be applicable for the whole assessment (assignment), even if only the component or part submission alone needs to be resubmitted. All students of the group would be considered as having committed an act of plagiarism irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all the students of the group.
If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and the penalty will be applied as per the policy for each student according to his / her history of violation.
Type 4: Variation of Type 1 and Type 2: In cases where the assessment consists of components or part submissions that could be a group assessment component (e.g. group assignment) and an individual assessment component (e.g. individual reflection), the following will be applicable:
Design of Thermal System (MECH 0009.1) – Spring 2021 –Assignment 1– A&B – QP
MEC_AMO_TEM_035_02 Page 9 of 10
a. If plagiarism is detected in the group assessment component, all students of the group will be considered as having committed an act of plagiarism, irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all students of the group. In such cases the group assessment component will be resubmitted.
If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and the penalty will be applied for each student according to his / her history of violation.
b. If plagiarism is detected in the individual assessment component, the individual assessment component will be resubmitted – if the student is eligible for resubmission-. The policy will then be applied to that student alone.
c. In both cases (a) and/or (b), the deduction in marks will be applicable for the whole assessment (assignment).
1.7. Types/Variation of Cases of Multiple Offences
If student is caught with multiple violations of same or different nature in different modules of the same semester, they will be considered as one offence and student will be penalized for each violation according to the type of the offence.
If student is caught with multiple violations of same or different nature in the same module of the same semester, then they will be considered as different offences and each will contribute to the overall count of AIV.

2. Late Submission Regulations:
It is the students’ responsibility to check all relevant timelines related to assessments.
As per the Assessment Policy at MEC, late submissions are allowed for one week (5 working days) for all UG modules with a penalty. In such cases, a deduction of 5% of the marks obtained for the submitted work shall be imposed for each working day following the last date of submission till the date of actual submission. Assessment documents submitted beyond a period of one week (5 working days) after the last date of submission will not be accepted and will be awarded a zero for that assessment. In cases where the submission has been delayed due to extenuating circumstances, the student may be permitted to submit the work without imposing the late submission policy stated above. The extended period of submission will be one week from the original last date of submission. In such cases, the student is expected to submit the supporting certificates on or before the original last date of submission of the assessment and the decision of extension rests with the faculty responsible for the assessment.The late submission policy shall be
