{ "item_title" : "Applied Refrigeration and Air Conditioning Technology", "item_author" : [" Logan Vincent "], "item_description" : "A cooling system can look perfect on paper and still freeze its evaporator, overheat its compressor or waste energy once it is installed. Understanding why that happens is the difference between replacing parts at random and solving the problem.Many learners meet this subject from two directions that never quite join. Thermodynamics texts present the refrigeration cycle as an elegant abstraction, while trade manuals teach careful procedures but rarely explain why they work. A technician who knows only the procedure struggles when a system behaves unexpectedly, and an engineer who knows only the theory struggles to turn a calculation into a working installation.Applied Refrigeration and Air Conditioning Technology connects the two. It builds from first principles towards field practice, and after each major derivation a practical interpretation explains which gauge reading will change, which component will work harder and what a sensible design or service decision looks like. It also reflects the field as it stands today, treating mildly flammable and natural refrigerants, inverter-driven compressors, electronic expansion valves, variable-refrigerant-flow systems and high-efficiency heat pumps as core material.What this book helps you doFollow every derivation step by step, with assumptions stated and every symbol and unit defined, so results can be applied in unfamiliar situations.Read the refrigeration cycle in the field, connecting pressures, superheat and subcooling to what is happening inside the circuit.Evaluate compressors, condensers, evaporators, cooling towers, expansion valves and refrigerant piping, and understand how each interacts with the rest of the system.Use the psychrometric chart to analyse air-conditioning processes and calculate the cooling and heating loads of a building.Plan installation, pressure testing, evacuation, charging and commissioning, then service systems with a step-by-step diagnostic procedure.Handle and recover refrigerant safely, calculate leakage rates and understand the precautions for flammable and high-pressure refrigerants.Practise with 179 fully worked examples and end-of-chapter practice problems with answers.Across eighteen chapters, the book covers thermodynamics and heat transfer, refrigerant properties, single-stage, multistage, cascade and transcritical carbon dioxide cycles, refrigerants and environmental regulation, absorption and alternative cooling, domestic, commercial and cold-chain refrigeration, thermal comfort and indoor air quality, air-conditioning systems and heat pumps, and electrical circuits, motors and controls. Appendices provide unit conversions, saturation tables for nine refrigerants, and properties of air and water, with a glossary and an index.It is written for diploma and technical-college students, engineering undergraduates in building services or thermal systems, and practising technicians who want to understand the reasons behind the work they already do. Instructors will find a structure that maps onto a two-semester course. SI units are used throughout, with inch-pound conversions in an appendix, and the book complements, rather than replaces, supervised training and any certification required where you work.Open the book and start connecting the theory to the equipment, so that the next system that behaves unexpectedly becomes a problem you can reason through rather than guess at.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/816/216/9798162168201_b.jpg", "price_data" : { "retail_price" : "150.99", "online_price" : "150.99", "our_price" : "150.99", "club_price" : "150.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
