Refrigeration and Air Conditioning: Principles, Calculations, Installation and Service for HVACR Technicians - Tapa blanda

Sinopsis

A gauge reading is only a number until you understand the physics behind it. A repair is only a parts change until you can prove what failed, why it failed, and that the system is right before you leave.
Refrigeration and Air Conditioning is a full-length HVACR technical textbook built for readers who want more than shortcuts and memorized pressures. It develops the trade from first principles, then carries those principles into calculations, installation practice, service measurements, commissioning, preventive maintenance, and systematic troubleshooting. The result is a structured path from understanding heat and pressure to diagnosing complete refrigeration and air-conditioning systems.
Built for technicians who want to understand what the readings mean
The book assumes high-school algebra and no prior HVACR knowledge. Concepts are introduced in sequence, calculations are worked step by step, and later chapters deliberately build on earlier ones. US customary units are presented first with SI equivalents throughout, making the text useful for North American equipment while remaining readable alongside metric documentation.
Inside, you will study:

• HVACR technician safety, professional responsibility, codes, standards, the authority having jurisdiction, and the EPA Section 608 regulatory framework.
• Matter, heat transfer, temperature, pressure, vacuum, saturation, and the pressure-temperature relationship that underpins refrigeration diagnosis.
• Refrigeration thermodynamics, enthalpy, entropy, pressure-enthalpy diagrams, refrigerating effect, compressor work, heat rejection, mass flow, and coefficient of performance.
• The vapor-compression cycle, superheat, subcooling, capacity, efficiency, condenser split, evaporator TD, and the measurements that turn operating data into diagnosis.
• Reciprocating, rotary, scroll, screw, and centrifugal compressors; condensers and evaporators; fixed orifices, TXVs, and EEVs.
• Refrigerants, lubricants, blends, glide, lower-GWP refrigerants, and the A2L transition.
• Psychrometrics, sensible and latent heat, humidity, comfort conditioning, cooling and heating load calculations, airflow, duct design, and static pressure.
• Residential split systems, heat pumps, ductless and inverter-driven equipment, VRF systems, commercial refrigeration, walk-ins, reach-ins, display cases, and ice machines.
• Chillers, cooling towers, hydronic systems, tools and instruments, piping, brazing, leak testing, evacuation, charging, electrical fundamentals, motors, and controls.
• Systematic troubleshooting, preventive maintenance, commissioning, documentation, and the repeatable measurement process that separates a verified repair from guesswork.

Theory is connected to the service call
Every chapter follows a consistent learning structure designed to turn technical knowledge into usable reasoning rather than isolated facts.

• Learning Objectives that define what the chapter is expected to teach.
• Worked Examples that show the given data, formula, unit substitution, intermediate steps, and final result.
• On the Job case studies that place the chapter’s principles inside realistic service situations.
• Safety Alerts and Common Errors that identify hazards and the diagnostic mistakes that create callbacks or equipment damage.
• A numbered Service Procedure ending with an explicit acceptance criterion, so completion is measured by a verified result rather than by simply performing steps.
• Chapter Summaries and Review Questions, with worked calculation answers and concept answers in the back matter.
