1. The Author and His Legacy

P.N. Ananthanarayanan is a renowned author in technical education. His writing style is distinctively student-friendly, characterized by a step-by-step approach to problem-solving. Unlike many theoretical texts that get bogged down in abstract derivations, Ananthanarayanan focuses on the application of principles. His works are widely used in engineering curriculums across India and other Asian countries due to their alignment with university syllabi. How to Study Effectively Using This Book Whether

Limitations

  • Likely dated in areas of refrigerant regulations, environmental standards, and newer refrigerant blends or low-GWP alternatives (depends on edition).
  • Advanced topics (detailed compressor design, CFD, modern control strategies, HVAC system simulation) not covered in depth.

How to Study Effectively Using This Book

Whether you get a physical copy or a legal PDF, here is a study strategy: natural refrigerants like R-290

  1. Start with Chapter 3 (VCRS). Do not skip the Carnot cycle. Master the T-s and p-h diagrams.
  2. Print the Psychrometric Chart (Chapter 9). PDFs are useless for psychrometry unless you print a large blank chart. Practice plotting all seven processes.
  3. Solve Every Numerical. The book’s strength is its solved problems. Redo them blindfolded, then attempt the unsolved exercises.
  4. Use Searchable PDFs. If you get an official PDF, use Ctrl+F to quickly find terms like "subcooling" or "bypass factor" during last-minute revision.
  5. Focus on Tables: Pay attention to refrigerant property tables and conversion factors—they are exam gold.

Part 3: Air Conditioning

  • Chapter 9: Psychrometry: This is the most critical section. Definitions of DBT (Dry Bulb Temperature), WBT (Wet Bulb Temperature), DPT (Dew Point Temperature), relative humidity, humidity ratio, and use of psychrometric charts.
  • Chapter 10: Air Conditioning Processes: Heating, cooling, humidifying, dehumidifying, mixing of air streams.
  • Chapter 11: Load Estimation: Calculating sensible and latent heat loads, solar radiation, infiltration, ventilation, and selecting equipment.
  • Chapter 12: Duct Design and Air Distribution: Equal friction method, velocity reduction method, and types of grilles/diffusers.

Part 2: Refrigerants and System Components

  • Chapter 5: Refrigerants: Properties of ideal refrigerants, classification (CFCs, HCFCs, HFCs, natural refrigerants like R-290, R-744), and environmental issues (ODP, GWP). This section is constantly updated in newer editions.
  • Chapter 6: Compressors: Reciprocating, rotary, screw, and centrifugal compressors—construction and working.
  • Chapter 7: Condensers and Evaporators: Types, heat transfer calculations, and maintenance.
  • Chapter 8: Expansion Devices: Capillary tubes, thermostatic expansion valves (TXV), and float valves.
