Beschreibung
HVAC design becomes unreliable when loads, airflow, ducts, fans, equipment, and controls are treated as separate tasks. A room may have a correctly calculated heat gain and still be uncomfortable if the supply-air state is wrong, the duct path is restrictive, the fan duty is mismatched, or the controls cannot respond to changing conditions. Many designers and technicians inherit disconnected rules of thumb: airflow per square foot, nominal equipment tonnage, arbitrary static-pressure allowances, or duct sizes chosen before the system resistance is known. These shortcuts can obscure the relationships that determine temperature, humidity, ventilation, pressure balance, noise, and delivered capacity. HVAC Loads, Airflow, and Duct Design Handbook presents a continuous engineering workflow from the building survey to measured system performance. It explains how indoor criteria and outdoor design conditions establish the calculation boundary; how psychrometrics links sensible and latent loads to supply-air conditions; how room, zone, system, and block loads differ; and how airflow, duct pressure, fan performance, equipment selection, controls, commissioning, and troubleshooting fit together. Inside, readers will learn how to: - distinguish heat gain, cooling load, heating load, equipment capacity, and energy use;- calculate envelope, solar, occupant, lighting, equipment, infiltration, and ventilation loads;- determine supply airflow from sensible and total air-side energy balances;- analyse static, velocity, and total pressure, system curves, fan laws, and index runs;- size supply and return ductwork, account for fitting losses and leakage, and plan balancing;- evaluate air terminals, room-air distribution, sound, equipment performance, zoning, and control sequences; and- verify design intent through testing, adjusting, balancing, commissioning, trend analysis, and fault diagnosis. Worked examples carry units through each step, and chapter practice problems reinforce both calculation and interpretation. The handbook uses U. S. customary or I-P units as the primary workflow while supplying SI equivalents, making the physical relationships clear for North American and international readers. Appendices provide symbols, psychrometric relationships, conversion tables, load forms, duct and balancing worksheets, equipment-selection checklists, commissioning forms, a glossary, standards guidance, and an index. This handbook is written for upper-level students, HVAC technicians moving into design, mechanical and building-services designers, commissioning and TAB personnel, instructors, and practicing professionals who need a calculation-centred reference. Because codes, standards, climate data, and product ratings change, it teaches the engineering method while directing readers to verify current adopted requirements and certified manufacturer data. Add this handbook to your technical library and begin tracing every HVAC decision-from load to airflow, pressure, equipment, controls, and measured performance-with greater clarity and discipline.
