NYS Clean Heat Contractor Training Bundle

This course is intended for individuals who would like to prepare for taking the EPA Section 608 examination but would also like a review or refresher of the fundamentals. The Refrigeration Cycle, Refrigerants, and Components course will provide an overview of the following: This course will prepare students and technicians for all sections of the EPA Section 608 examination (Core, Type I, Type II, and Type III) or Universal certification. The course includes the EPA Section 608 Certification Examination. Review the lectures and take the practice quiz.

The Core contains 25 general knowledge questions relating to stratospheric ozone depletion, rules and regulations of the Clean Air Act, the Montreal Protocol, refrigerant recovery, recycling and reclaiming, recovery devices, substitute refrigerants and oils, recovery techniques, dehydration, recovery cylinders, safety, and shipping. Type I contains 25 sector-specific questions pertaining to small appliances. Type II contains 25 sector-specific questions pertaining to medium and high-pressure appliances and Type III contains 25 sector-specific questions pertaining to low-pressure appliances.

Type 1 covers persons who maintain, service, repair, or dispose of small appliances and must be certified as Type I technicians. A small appliance is defined as a pre-assembled unit, hermetically sealed and factory-charged with 5 lbs. or less of refrigerant. Examples include equipment such as water coolers, window units, refrigerators, freezers, de-humidifiers, residential ice machines, and package terminal air conditioning. Split- systems are not included in Type I.

Type 2 covers persons who maintain, service, repair, or dispose of appliances containing more than 5 lbs. of refrigerant, or if the installation of such equipment requires refrigerant charging, must be certified as Type II technicians. Type II certification does not include small appliances or motor vehicle air-conditioning (MVAC) systems.

Type 3 covers persons who maintain, service, repair, or dispose of low-pressure appliances, such as centrifugals and chillers, and must be certified as Type III technicians. Low-pressure appliances operate with low-pressure refrigerants, which have pressures of 30 psig, or lower, at a liquid-phase temperature of 104°F. HCFC-123, used in chillers, is a “low-pressure refrigerant” under EPA’s Section 608 regulations to replace CFC-11.

Take these practice exams as many times as you want. You need 70% to pass. Don't forget the P/T Chart.

This course is self-paced, so you don’t need to be logged in at any specific time. You can get started immediately after you enroll and the course materials will remain in your account with minimum guaranteed access for 12 months (1 year) after enrollment.

This week provides an overview of the course, learning objectives, and background information on air-source heat pumps. It discusses the benefits of air-to-water heat pumps, and trends that point to a growing market in North America.

This week presents the “nut & bolt” details of working with modern air-to-water heat pumps. It examines the thermal performance of modern vapor/compression air-to-water heat pumps, freeze protection options, use of buffer tanks, modulating versus fixed speed heat pumps, and integration of an auxiliary boiler. They details will all be applied in the example systems described later in the course.

This week focuses on heat emitter options and the important of designing the heating distribution system to operate at low supply water temperatures. Several heat emitters are discussed, and preferred piping layouts are shown.

The week is devoted to smaller scale chilled water cooling, which allows air-to-water heat pumps to provided zoned cooling and dehumidification. Both sensible and latent cooling are described along with terminal unit options including radiant panel cooling.

This week presents several complete system designs for heating cooling and ancillary loads. They include piping schematics, control concepts, electrical wiring, and descriptions of operation.

This is our last module but you still have access to the all of course materials for 12 months (1 year), so keep working and you'll be able to complete the course at your own pace. After your year of access expires you can optionally extend access with a HeatSpring Membership. Enjoy the course and keep in touch!
