The Sheet Metal/HVAC Pro Calc is a versatile calculator that enables tradesmen to calculate complex problems with dedicated key functions that are labeled in standard industry terms. The calculator has other advanced built-in construction-math functions to enable HVAC and sheet metal tradesmen to do their work alongside other trades. In addition to the built-in functions, this calculator can handle order of operation, using the parenthesis operators. It can also perform square, cube, square root, and cube root calculations. Plus, it works as a regular calculator with typical symbols. The calculator can be used to determine ArcK constant for convenient Arc length solutions. And it has an offset functions for "S-shaped" bends in ductwork. It can also help solve the layout for wrapper length, centerline radius, and the angle. Features CUSTOM HVAC & SHEET METAL functions let you simplify Test and Balance (TAB) with built-in Fan Law function: CFM, RPM, SP and BHP; velocity and velocity pressure: FPM, VP, MPS, KPa; ArcK constant for convenient Arc length solutions; and offset functions FUNCTIONS AND TERMINOLOGY consistent with sheet metal and HVAC trade terminology; x, y, r (radius), theta and Seg Radius functions; works in and converts between feet-inch-fractions, decimal feet and inches and metric also converts between polar and rectangular coordinates PARENTHESIS OPERATORS allows you to easily enter complex formulas; order of operations calculations retain familiar mathematical hierarchy as a default preference; trigonometric operation and sequence; and you can calculate square, square root, cube, and cube root; easy non-90 triangles and right-angle solutions for ductwork length and angles MEMORY STORAGE conveniently stores frequently used constants or interim solutions; Memory swap lets you easily insert stored values into current calculations and simultaneously store calculated values while recalling and displaying Memory contents; other settable User Preferences INVALUABLE TRADE TOOL PAYS FOR ITSELF by reducing headaches, saving time, and preventing expensive material errors on all your projects. Comes with a rugged shock, dust and moisture-resistant Armadillo Gear protective case, quick reference guide and complete user's guide, a long-life battery, and a one-year limited warranty.

Heating and Cooling Load Calculations is a handbook that covers various concerns in calculating heating and cooling. The title provides a logical study of the physical and engineering factors that affect the heating and cooling load. The coverage of the text includes heat transfer; heating loads and its reduction; and design temperature conditions. The text also covers the cooling design conditions and the components of cooling load and its reduction. The book will be of great use to both student and professional engineers.

A comprehensive handbook and essential reference, providing instant access to all the data, calculations, and equations needed for modern HVAC design.

The ultimate reference book on the most frequently used HVAC data, chock-full of equations, data, and rules of thumb--a necessary addition to any library for mechanical, architectural, and electrical engineers, HVAC contractors and technicians, and others. Features over 216 equations for everything from air change rates to swimming pools to steel pipes. Includes both ASME and ASHRAE code information, and follows the CSI MasterFormat "TM."

Heating Ventilation and Air Conditioning by J. W. Mitchell and J. E. Braun provides foundational knowledge for the behavior and analysis of HVAC systems and related devices. The emphasis of this text is on the application of engineering principles that features tight integration of physical descriptions with a software program that allows performance to be directly calculated, with results that provide insight into actual behavior. Furthermore, the text offers more examples, end-of-chapter problems, and design projects that represent situations an engineer might face in practice and are selected to illustrate the complex and integrated nature of an HVAC system or piece of equipment.

This guideline defines ventilation and then natural ventilation. It explores the design requirements for natural ventilation in the context of infection control, describing the basic principles of design, construction, operation and maintenance for an effective natural ventilation system to control infection in health-care settings.

"This manual focuses on the calculation of cooling and heating loads for commercial buildings. The heat balance method (HBM) and radiant time series method (RTSM) (as well as how to implement these methods) are discussed. Heat transfer processes and their analysis, psychrometrics, and heating load calculations are also considered"--
