{ "item_title" : "The Sound of Failure", "item_author" : [" Charles Nehme "], "item_description" : "The modern built environment is a complex tapestry of interconnected mechanical systems, with the Heating, Ventilation, and Air Conditioning (HVAC) system serving as its critical heart and lungs. While we rely on instrumentation and digital controls to manage these systems, the human ear remains one of the most immediate and reliable diagnostic tools available. Every chiller hum, pump thump, and fan whine carries a story-a hidden message about the system's health, efficiency, or imminent failure.This book, The Sound of Failure: A Diagnostic Guide to HVAC System Noises, is dedicated to teaching maintenance professionals, engineers, and facility managers how to decode the acoustic language of their mechanical rooms. We move beyond simple it's loud observations to offer a structured, systematic approach to noise analysis. By learning to distinguish between the normal operating symphony and the discordant sounds of distress-be it a screw compressor surging, a pump cavitating, or a cooling tower fan wobbling-you gain the power to implement predictive maintenance, reduce costly downtime, and ultimately, extend the life and optimize the performance of critical HVAC assets. Turn off the gauges for a moment, and learn to listen. The solution is often in the sound.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/827/485/9798274859004_b.jpg", "price_data" : { "retail_price" : "35.00", "online_price" : "35.00", "our_price" : "35.00", "club_price" : "35.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
