An electrical fault can look like a refrigerant problem. Poor equipment selection can create comfort and humidity complaints that charging alone will never correct.Applied HVACR Systems takes a complete systems approach to HVACR, connecting refrigeration, air conditioning, heat pumps, electrical systems, controls, airflow, building loads, commissioning, and diagnostics in one practical technical resource.Written for HVACR students, apprentices, technicians, instructors, and early-career professionals, this textbook bridges engineering principles with real-world measurements, calculations, service procedures, and diagnostic reasoning.Inside This Book- Thermodynamics, heat transfer, and psychrometrics- Vapor-compression refrigeration cycles and refrigerant properties- Compressors, evaporators, condensers, metering devices, piping, and system protection- Electrical fundamentals, motors, ECM technology, sensors, and controls- Airflow, duct systems, ventilation, static pressure, and indoor air quality- Load estimation, equipment selection, and system matching- Installation, startup, commissioning, and performance verification- Heat pumps, dual-fuel systems, defrost, and cold-climate applications- Ductless systems, inverter equipment, VRF, and variable-capacity technology- Commercial refrigeration and light-commercial HVACR- A2L refrigerant safety, charging, recovery, evacuation, and leak detection- Troubleshooting, diagnostics, maintenance, and performance optimizationThe book emphasizes measurement-based diagnosis rather than guesswork. Readers learn how to connect temperature, pressure, airflow, voltage, current, static pressure, humidity, superheat, subcooling, sensor data, and control commands to actual system behavior.It also includes 50 technical figures and diagrams, worked examples, engineering calculations, practice problems with answers, key equations, troubleshooting tools, commissioning worksheets, a glossary, appendices, and a detailed index.Modern HVACR work increasingly includes heat pumps, inverter compressors, electronic expansion valves, communicating controls, variable-capacity systems, A2L refrigerants, and advanced diagnostics. This book brings those technologies together with the fundamentals needed to understand why systems operate correctly-and why they fail.Whether you are preparing for a career in HVACR, strengthening your technical foundation, teaching future technicians, or expanding your knowledge of modern equipment, Applied HVACR Systems provides a practical framework for understanding, installing, commissioning, servicing, troubleshooting, and evaluating HVACR systems with greater technical confidence.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/817/843/9798178435045_b.jpg", "price_data" : { "retail_price" : "99.99", "online_price" : "99.99", "our_price" : "99.99", "club_price" : "99.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
