Modern Refrigeration and Air Conditioning, 22nd Edition is focused on closing the gap from students to technicians with our commitment to top-quality coverage of fundamentals and the latest technology. This classic is an excellent blend of theory, skill development, and service techniques to help you learn how to install and service refrigeration and HVAC systems.

Addresses the design and installation of fuel gas systems and gas fired appliances through prescriptive and performance requirements.

Building on a history of duct construction standards nearly 100 years old, the flagship SMACNA HVAC Duct Construction Standard – Metal & Flexible 4th edition represents the state of the art in the sheet metal duct fabrication and installation requirements. Significant changes for the 4th edition include; flat oval tables for positive/negative pressure applications; spray and aerosolized duct sealants; non-fiberglass duct liner applications; added information on spiral duct fittings; updates to duct hanger requirements; flexible duct hanger spacing and support bracing.

The New Fifth Edition of Manual N® details the load calculation procedure that addresses the advances in the commercial construction industry: new materials, methods of assembly, and operational requirements. It provides instruction to help contractors and designers satisfy new, and often conflicting, energy, ventilation, and comfort requirements. The new Manual N is divided into four sections providing both a quick and comprehensive procedure for commercial load calculation.

• Section 1 Abridged Procedure: Basic instructions to perform commercial load calculations, on buildings of three stories or less. Supports a simplified hand calculation.
• Section 2 Advanced Topics: Provides enhanced procedures, capabilities, and sensitivities (requires computer software to process).
• Section 3 Tables: Provides input for the worksheets and determinations needed for the abridged (N5ae) and full (N5) procedures.
• Section 4 Appendices: Provides supporting materials and details on the N5ae and N5 applications...(640 pages)

The IPC provides minimum regulations for plumbing facilities in terms of both performance and prescriptive objectives, and provides for the acceptance of new and innovative products, materials, and systems.

The LP-Gas Code is your source for the latest requirements for LP-gas installations, including container construction, piping design, and separation of containers from homes, stores, schools, and other buildings. The code also provides comprehensive coverage of handling LP-Gas during transfer and storage, including operator qualifications, maximum filling quantity in containers, and pre-transfer inspections to ensure containers are fit for continued service.

The 2010 NFPA 13, Installation of Sprinkler Systems is revised and updated with added criteria based on recent fire testing and studies performed by the Fire Protection Research Foundation. Chapter 20: Special Designs of Storage Protection presents requirements for the protection of three new special storage arrangements, including carton records storage with catwalk access, and high bay records storage. This edition also adopts the SEI/ASCE 7 approach for load calculations and introduces new zone-of-influence tables for Schedule 5 steel pipe, CPVC, and Type M copper tube. An important new method to calculate rack shelf area takes the placement of loads into consideration.

Uses:

• Sizes metal ducts, lined metal ducts duct board airways, and wire helix flexible ducts.
• Converts round shapes to equivalent rectangles.
• Correlates available pressure with total effective length and friction rate (Manual D sizing calculations).
• Converts velocity into velocity pressure and vice versa.
• Corrects for altitude and temperature

Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues). The Manual D has been significantly revised to include:

• Updated and expanded VAV guidance, with detailed examples
• Impacts of excess length, sag and compression in flexible ducts
• New equivalent length values for flex duct junction boxes

Manual D provides:

• A single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials
• System operating point (supply Cfm and external static pressure), and airway sizing for single-speed and multi-speed (ECM) blowers
• A method for determining the impact of duct friction and fitting pressure drop on blower performance and air delivery
• The most comprehensive equivalent length data ever published

You can apply the Manual D procedure to constant volume systems and zoned variable air volume systems, over a full range of duct construction materials. Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues).

Compact and pocket-sized, this handy reference contains thousands of facts and figures relevant to pipefitters, steamfitters-anyone concerned with layout and installation of pipe.

The NASCLA Contractors Guide to Business, Law and Project Management is organized into three sections.

Part 1 focuses on planning and starting your business. This section will help you formulate a business plan, choose a business structure, understand licensing and insurance requirements and gain basic management and marketing skills.

Part 2 covers fundamentals you will need to know in order to operate a successful construction business. This section covers estimating, contract management, scheduling, project management, safety and environmental responsibilities, and building good relationships with employees, subcontractors, and customers.

Part 3 provides valuable information to assist you in running the administrative functions of your business. Financial management, tax basics, and lien laws are covered. Effective management of these areas of business is vital and can cause you serious problems if you do not give them proper attention.
