TX-CR-Class B Commercial Refrigeration - Class B (2024-09-04)

This durable two-sided plastic sizing wheel comes with a complete instruction manual for residential and commercial duct-sizing procedures. Designed by Hank Rutkowski.

Used to determine how much heating/cooling a home needs to stay cool and dry in the summer and warm in the winter. This load calculation process was developed by engineers in the heating and air conditioning industry and has been used for decades to accurately size heating and air-conditioning equipment. After completing this load calculation process, one can choose a properly sized piece of machinery to satisfy the load.

The ANSI-recognized national standard for residential HVAC duct design will help you design a duct system in less time. The popular and accurate procedure has been revised to include updated and expanded VAV guidance, with detailed examples; impacts of excess length, sag and compression in flexible ducts; and new equivalent length values for flex duct junction boxes. Manual D, from the Air Conditioning Contractors of America (ACCA), provides a single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials.

The essential companion to Manual J! Manual S shows you how to select and size heating and cooling equipment to meet Manual J loads based on local climate and ambient conditions at the building site. Manual S covers sizing strategies for all types of cooling and heating equipment, as well as how to use comprehensive manufacturer’s performance data on sensible, latent, or heating capacity for various operating conditions.

The 2021 edition of the Uniform Mechanical Code (UMC®) represents the most current approaches in the mechanical field. It is the seventh edition developed under the ANSI Consensus process is designated as an American National Standards by the American National Standards Institute (ANSI). Furthermore, it addresses specific provisions for low flammability refrigerants such as A2L and B2L; which makes it one of the first codes in the industry to address specific provisions for these low Global Warming Potential (GWP) refrigerants. Contributions to the content of this code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, labor, manufacturers, research/standards/ testing laboratories, special experts and users.

2021 International Fuel Gas Code addresses the design and installation of fuel gas systems and gas-fired appliances through requirements that emphasize performance.

The OSHA 29 CFR 1926 Construction Regulations book offers convenient access to vital safety guidance for both employers and employees, aiding in the prompt identification of potential hazards on any job site. Its user-friendly design features a two-color layout, simplifying navigation and comprehension of regulations. It encompasses all 1926 regulations, along with 1903 regulations on inspections, citations, and penalties, as well as 1904 regulations concerning record keeping and reporting of occupational injuries and illnesses. Additionally, select 1910 regulations relevant to construction industries are included. The book highlights regulation changes between releases and provides easy-to-access OSHA interpretations, aiding in clarity and reference. Essential documents such as OSHA Form 300 and the Cancer Policy are incorporated. In-Cite Referencing to applicable 1910 regulations is provided for further context. Lastly, the book outlines the Most Frequently Cited Standards preceding relevant Subparts, enhancing its utility as a comprehensive safety resource.

Establishes minimum regulations for mechanical systems using prescriptive and performance-related provisions. The IMC was developed with broad-based principles that make possible the use of new materials, methods and design.

Important changes in the edition include:

Clothes dryer exhaust terminals required to be at least 3 feet from any opening into a building.
Polyurethane spray-applied foam on the exterior of ducts in attics and crawl spaces required to meet specific smoke and flame index limits.
Fire and smoke dampers must be provided with approved access for inspection and maintenance.
Refrigerant tables updated to include new refrigerants.
Addition of condensate termination identification markings and discharge restrictions.
Approved factory-built combination intake/exhaust terminations permitted, relaxing separation requirement.
30% reduction in minimum mechanical ventilation for whole-house balanced ventilation systems.
Continuous operation requirement for manicure and pedicure station exhaust systems.
Grease duct horizontal cleanout required within 3 feet of a horizontal discharge fan.
