Students who already own all references
Modern Refrigeration and Air Conditioning, 21st 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.
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
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.
The UMC provides complete requirements for the installation and maintenance of heating, ventilating, cooling and refrigeration systems, while at the same time allowing latitude for innovations and new technologies. Key changes to the 2021 UMC include:
- New Appendix F – Geothermal Energy Systems
- New guards and rails requirements for installation of equipment and appliances on roofs
- New ventilation requirements for transient and nontransient occupancies
- New ventilation requirements for indoor air quality for residential occupancies
- Revisions to the requirements for air ducts, including factory-made air ducts and dampers
- New provisions for factory-built grease ducts
- New provisions for refrigeration systems, including pressure-limiting devices and hydrostatic expansion
- Revisions to the sizing requirements for natural gas and propane piping systems
- Modifications to the pressure rating requirements for hydronic piping applications
- New requirements for fuel gas piping appliance shutoff valves, test pressure, and overpressure protection devices
- New tube fastener provisions for radiant heating and cooling
- New requirements for residential compressed natural gas (CNG) fueling systems
- New fire-extinguishing equipment and carbon monoxide detection requirements for exhaust systems
Important changes in the 2021 IMC 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.
Key changes in the 2021 IFGC® include:
- The termination of concealed condensate piping requires marking to indicate if it is the primary drain or the secondary drain.
- Press-connect joints are acceptable for high pressure (over 5 psig) applications indoors.
- Commercial cooking appliances are not allowed within dwelling units.
Manual D - Residential Duct Systems, 3rd Edition
See Details
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).
Manual J - Residential Load Calcs (Full Edition)
See Details
Manual J 8th Edition is the national ANSI recognized standard for producing HVAC equipment sizing loads for single-family detached homes, small multi-unit structures, condominiums, town houses, and manufactured homes. A proper load calculation, performed in accordance with the Manual J 8th Edition procedure, is required by national building codes and most state and local jurisdictions.
Manual S shows you how to select and size heating and cooling equipment to meet loads for a particular home, which are based on local climate and home construction specifics. Contractors in Miami, Phoenix, and Seattle - all extremely different climates - would never use the same equipment and expect the same results. Manual S provides sizing requirements for 11 types of cooling and heating equipment, as well as in-depth explanations and examples of how to use manufacturer's performance data.
New for this edition:
- Contains new sizing rules that recognize multi- and variable speed equipment with larger over sizing limits.
- Covers 11 types of equipment (previous version covered only four).
- Heat pumps in heating dominated locations have an optional over-sizing procedure.
- There are an increased number of example problems for Manual S procedures, as well as explanations of details/nuances (for contractors and educators).
- The book is reformatted so the first sections contain mandatory code official language.

- New provisions for Type I and Type II exhaust systems and product conveying ducts.
- New sizing provisions for duct systems, duct leakage testing requirements, installations and closure requirements for flexible air ducts, and new provisions for air dispersions systems (Chapter 6)
- New requirements for pressure regulators and electric furnaces (Chapter 9)
- New refrigerant system requirements, such as A2L and B2L low flammability refrigerants; machinery room requirements such as access, openings, detectors, and ventilation systems; and new pressure limiting-device provisions for compressors (Chapter 11)
- New pressure testing requirements for piping and components, expansion tanks, and materials for hydronic systems (Chapter 12)
- New requirements for piping material, overpressure protection and gas piping installation for fuel gas piping systems (Chapter 13)

- A new exception was added to recognize Type I kitchen hoods listed for clearances to combustibles of less than 18 inches.
- Added coverage for a newer type of non-metallic duct, phenolic duct.
- New coverage for high volume large diameter fans (HVLD), also referred to as high volume low speed (HVLS) fans.
- Relaxed requirements for sealing of duct joints and seams for Snap- and Button-lock duct joints located within the thermal envelope.
Addresses the design and installation of fuel gas systems and gas fired appliances through prescriptive and performance requirements.
