ESCO Institute s EPA Section 608 Preparatory Manual is a valuable tool that has been prepared to help students and technicians alike prepare for their EPA Section 608 certification examination. This 27-page manual reflects the NEW REGULATIONS that HVACR technicians must observe to be in compliance with the most recent changes and additions to EPA guidelines

Depending on what part of the country that you reside in, gas-burning heating systems can be either an absolute necessity or a rarity. For those that maintain, service and install gas heating systems or those just looking for a more in-depth source of accurate information, this modular training program focuses on furnaces and boilers that burn natural gas or LP. The combustion of gas to generate heat can be dangerous and should be thoroughly understood by HVAC technicians. This program covers many facets of gas heating including: combustion, system components and controls, heating sequences, installation, and troubleshooting. Through advancements in technology, modern heating systems have become far more efficient than their predecessors. Integrated circuit boards and electronic ignition systems have replaced the mechanical controls and manually lit pilots of older systems. Today, technicians may encounter furnaces or boilers that are older than they are, complex high-efficient systems, or anything in between. It is critical that they have a working knowledge of all these systems. This manual provides students and practicing technicians with the information and knowledge necessary to safely work on systems that incorporate gas combustion to provide heat. The information to service, maintain, and install these systems is also presented in an easy-to-understand format. The manual is full of color images and diagrams and includes end-of-chapter worksheets.

Heating, Ventilating, and Air Conditioning The authoritative resource providing coverage of all aspects of HVAC, fully updated to align with the latest HVAC technologies and methods Now in its Seventh Edition, Heating, Ventilating, and Air Conditioning has been fully updated to align with the latest technologies and industry developments while maintaining the balance of theoretical information with practical applications that has prepared many generations of students for their careers. As they work through the book, students will become familiar with different types of heating and air conditioning systems and equipment, understand processes and concepts involving moist atmospheric air, learn how to provide comfort to occupants in controlled spaces, and gain practice calculating probable heat loss/gain and energy requirements. A companion website includes additional multiple-choice questions, tutorial videos showing problem-solving for R-value calculation, and Excel spreadsheets that can be used for practice calculations. The Seventh Edition includes new coverage of ductless A/C systems, heat exchangers and hybrid heat pumps, geothermal heat pumps, energy-efficient equipment, and UV principles of air quality treatment of airborne viruses like COVID-19. Heating, Ventilating, and Air Conditioning includes detailed coverage of topics such as: Common HVAC units and dimensions, fundamental physical concepts, and system selection and arrangement Types of all-air systems, air-and-water systems, all-water systems, and decentralized cooling and heating Moist air and the standard atmosphere, fundamental parameters, adiabatic saturation, and wet bulb temperature and the psychrometric chart Outdoor and indoor design conditions, transmission heat losses, infiltration, heat losses from air ducts, auxiliary heat sources, and intermittently heated structures Heat gain, cooling load, and heat extraction rate, and application of cooling load calculation procedures Selection of pumps and fans, and duct HVAC sizing Heating, Ventilating, and Air Conditioning helps prepare students for the industry by connecting the content to ASHRAE standards and by introducing coverage of software tools commonly used in HVAC design. The text is suitable for one- or two-semester HVAC courses taught at junior to graduate levels in various engineering departments.

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 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.
