To give you a taste, here is a paraphrased problem from the "Hot" section:
Problem: A steam-to-water heat exchanger uses 15 psig saturated steam. The condensate leaves at 210°F. The water enters at 140°F and leaves at 180°F at 100 GPM. Calculate the steam flow rate in lb/hr. hvac book by anant narayan hot
Solution approach (from Narayan):
This is a standard problem, but Narayan follows it with variations including subcooling, non-condensable gases, and fouling. To give you a taste, here is a
“Hot air rises, but hot ducts expand.” This chapter provides thermal expansion coefficient tables specifically for flexible and rigid ducts exposed to direct sunlight or industrial process heat. Narayan’s formula for calculating heat gain in return air plenums is a standout feature, often cited by LEED professionals. This is a standard problem, but Narayan follows
While the book is a favorite among students, it has not neglected the professional engineer. HVAC is a field where theory meets harsh reality. A system designed on paper must function efficiently under fluctuating weather conditions, varying occupancy loads, and energy constraints.
Anant Narayan’s text is lauded for its practical orientation. It touches upon:
