Suggested Student Activities:
Other than the classroom and laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group and prepare reports of about 5 pages for each activity, also collect/record physical evidences for their (student’s) portfolio which will be useful for their placement interviews:
- Prepare journals based on practical performed in laboratory.
- Follow the safety precautions.
- Use various mechanical measuring instruments and equipments related to Heating ,Ventilation and air conditioning
- Read and use specifications of the Refrigration and air conditioning equipments.
- Library / Internet survey of HVAC systems
- Prepare power point presentation or animation for understanding constructional details and working of different Centralised air conditioning systems.
- Visit nearby malls/auditoriums/commercial complex/Dairys/Cold storages to identify different componetnts of Refrigeration and air conditioning system.

Suggested Micro-Projects
Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.
The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs.
A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:
- Prepare a duct layout of your institute building from AHU
- Prepare a chart of showing all the cmponents of house hold refrigerator.
- Prepare a demonstration model of cold storage.
- Calculate Refrigeration capacity of split air conditioner.
- Collect different air outlet devices used in Central air conditioning system
- Download catalogue of Refrigeration compressors.
- Prepare display chart of types of refrigerant used in commercial and Industrial applications.
- Visit to nearby Centtral air conditioning plant / Malls/ Showrooms and collect information regarding air conditioning
- Conduct market survey of household refrigerators, make, capacity, arrangement, feartures, commercial terms etc
- Conduct market survey of window air conditioner make , capacity, arrangement, feartures, commercial terms etc
- Collect information of automobile air conditioning of different vehicles.
