Taschenbuch. Condición: Neu. Neuware - You can do the arithmetic. Can you turn a gauge reading into the right next move Textbook of Math for HVACR 2026-2027 is built for HVACR apprentices and service technicians who need trade math to work the way the job actually works: a reading comes in off a gauge, a tape measure, or a nameplate, and a decision has to come out the other end. This book covers the full span of math an HVACR technician actually uses - whole numbers through algebra and trigonometry, electrical calculations, load calculations, duct sizing, psychrometrics, refrigeration-cycle math, piping and fan laws, and the cost and efficiency math a finished job still needs - and every topic is organized around Featuring The Field-Reading Calculation Pathway, a repeatable five-step sequence that turns any field reading into a confident decision: Read the Field Value, Convert to Working Units, Apply the Governing Relationship, Check Reasonableness, Decide the Next Action. Once a reader has walked that sequence through a few dozen different calculations, the Pathway itself becomes the transferable skill, ready for whatever new formula the trade presents next. Inside, You Will Find: - Fourteen chapters covering the complete HVACR applied-math curriculum, from foundational arithmetic through refrigeration-charge and fan-law calculations- Mandatory Step-by-Step worked examples for every calculation type, never a bare formula with no explanation- Real, natively typeset mathematical notation - true fractions, exponents, and radicals - the same way any professional engineering or trade textbook presents a formula- KEY EQUATION callout blocks for every governing formula a technician needs to recognize and recall on the job- The Field-Reading Calculation Pathway threaded through every chapter, plus The Field-Reading Calculation Index at the back of the book, cross-referencing every Pathway instance by field task for fast lookup under time pressure- Full coverage of electrical calculations, heat-loss and heat-gain load calculations, duct sizing and static pressure, psychrometrics, refrigerant charge, piping and fan laws, and SEER2/EER2/COP efficiency metrics and job costing- A Trade/Apprenticeship register that speaks like a working technician, not a lecture hallKeep it on the bench, in the truck, or next to the apprenticeship coursework - this is the math reference built to go from a field reading to a field decision, every time.…

Taschenbuch. Condición: Neu. Neuware - Select the whole plant-not just the machine. Applications of HVAC Water Chillers and Cooling Towers is a professional reference for mechanical engineers, HVAC designers, commissioning providers, facility engineers, and experienced technicians who must turn a cooling duty into a reliable central plant. It closes the gap between catalog performance and field application by connecting load shape, climate, temperature, hydraulics, heat rejection, controls, water, access, safety, and lifecycle economics. The Application-Fit Decision Matrix carries every major choice through duty, boundary conditions, evidence, coordination, and consequence. The book progresses from application thinking and corrected performance through chiller technology, modular sizing, chilled-water configurations, pumps, piping, condenser-water systems, tower selection, controls, resource economics, special modes, specialized facilities, water management, commissioning, troubleshooting, and retrofit. Calculations remain tied to physical meaning, while chapter matrices preserve the assumptions and acceptance criteria that procurement and commissioning teams need. Inside, You Will Find Load-profile methods for capacity, module, turndown, and redundancy decisions Application guidance for air-cooled, water-cooled, centrifugal, screw, scroll, magnetic-bearing, and absorption machines Hydraulic analysis for primary-secondary, variable-primary, district, pumping, pressurization, valve, and low-delta-T decisions Cooling-tower selection using range, approach, wet-bulb, cell arrangement, siting, acoustics, drift, plume, and freeze exposure Whole-plant sequences with proofs, delays, staging, reset, optimization, fallback states, and alarms Lifecycle methods spanning energy, water, treatment, sewer, maintenance, replacement, downtime, and measurement Heat-recovery, waterside-economizer, thermal-storage, data-center, healthcare, process, campus, and climate-specific applications Narrated worked examples, native engineering equations, technical figure briefs, and the indexed Application-Fit Matrix Compendium Keep this reference beside the basis of design, equipment selections, controls narrative, and commissioning plan whenever a central cooling plant decision must survive real operating conditions.…

Paperback. Condición: new. Paperback. When a motor won't start and the fault in front of you doesn't match the diagram in the manual, what do you check first, and why?This field manual is written for industrial electricians, plant maintenance technicians, and advancing apprentices who need more than theory when they're standing at an open panel with a process down. It moves from the electrical fundamentals every industrial technician relies on daily, safety and lockout/tagout, circuit theory, three-phase power, conductor sizing, overcurrent protection and grounding, through motor theory, control circuits, starters, and reduced-voltage starting, into the systems that dominate modern plant floors: variable frequency drives and programmable logic controllers. Every chapter carries the book's Featuring The Fault-to-Fix Decision Path, a four-part reasoning block, Symptom, Likely Cause, Verification Test, Corrective Action, built around the exact judgment call an experienced technician makes when a fault doesn't match the textbook. The book closes with a full Master Index consolidating every Decision Path instance by symptom and by component, turning the manual into a quick-reference a technician can go back to on the job, not just read once and shelve.Inside, You Will FindTwenty chapters covering safety and lockout/tagout, circuit theory, three-phase power, conductors and NEC-based wiring, overcurrent protection and grounding, transformers, AC/DC motor theory, motor nameplate sizing, control circuits and ladder logic, starters and overload protection, reduced-voltage starting, VFD theory and fault diagnostics, PLC architecture and ladder logic programming, and systematic troubleshooting.The Fault-to-Fix Decision Path, a repeated four-part diagnostic reasoning block (Symptom, Likely Cause, Verification Test, Corrective Action) embedded throughout every chapter at the exact points a real fault is likely to occur.A closing Fault-to-Fix Master Index, indexing every Decision Path instance in the book by symptom and by component for fast field lookup.Mandatory Step-by-Step worked examples for every calculation, conductor sizing, overload trip class selection, VFD parameter commissioning, and more, with real inline and displayed mathematical notation, never spelled-out prose or raw formula text.Practical VFD fault code cross-reference guidance organized by underlying drive stage (rectifier, DC bus, inverter) so the reasoning transfers across manufacturers, not just one brand's fault code list.Ladder logic coverage spanning hardwired relay control through PLC-based motor control integration, including forcing, online editing, and safety practice.Full-color and line-art technical figures throughout: schematics, ladder diagrams, wiring diagrams, procedural sequences, and technical photography, drawn from a locked visual inventory matched to the sub-discipline.Currency-flagged code and safety guidance (NEC, OSHA, NFPA 70E) with a clear disclaimer that field values must always be verified against the current adopted code and the equipment nameplate.Keep it on the tool cart, not on a shelf. Whether you're commissioning a new VFD, chasing an intermittent control circuit fault, or mentoring an apprentice through their first lockout/tagout, this manual is built to be reopened on the job, not just read once. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…
