ME350: Refrigeration and Air-Conditioning

Prof S.L. Bapat

Description:

This course gives an idea about the wide range of applications and devices used for refrigeration and air-conditioning in varied climatic conditions. Air-conditioning requirements in an airplane at an altitude of 10000m from ground are different from those in residential and commercial complexes. This course deals with the design of RAC systems in different scenarios. It is an application of concepts in thermodynamics and it explains various cycles which are designed for refrigeration and air conditioning.

Motivation:

Refrigerators and Air-conditioners are a vital part of our daily lives. This course provides an understanding of the working principles that lie behind designing these devices. It is an application based course with parallels in Applied Thermodynamics (ME316) and the concepts studied are useful especially during interviews.

Course Content:

1) Introduction

2) Refrigeration Cycles

3) Analysis of vapour compression system

4) Low temperature vapour compression systems

5) Refrigerants, gas cycle refrigeration systems

6) Ammonia-water vapour absorption refrigeration systems

7) Miscellaneous refrigeration systems, applications

8) Thermodynamic relations for properties of moist air, psychrometric chart and processes

9) Evaporative cooling, basic of load estimation and space air distribution, Bypass factor.

Grading Structure:

2 quizzes: 20%, Midsem: 30%, Endsem: 50%
