This ½ day program goes through the Building Science behind Heat, Moisture and Pressure transfers that occur dynamically each day. Using the principles found in the “Second Law” we can locate problems affecting buildings. This is part of the Series dealing with Building and Pressure Diagnostics.
It is recommended that participants take this course prior to attending the ACCA Manual D, Advanced Manual D. This computer-based class will cover whole house and room-by-room ACCA manual J Version 8 Load Calculation methods. The instructor will also review the ACCA Manual S Equipment Selection Manual.
Special Note: Computers will be provided, but students should have basic computer skills such as being able to save and rename files, and use a mouse to click and drag.
It is recommended that participants attend this class prior to attending the Advanced ACCA Manual D class. This class provides a review of the ACCA Residential Design System and approved software, Manual D procedure, and proper documentation. Learn how to achieve efficiency compliance while optimizing ductwork for competitive pricing and comfort. North American Technician Excellence (NATE) continuing education credits are available for this class.
It is recommended that participants attend the ACCA Manual J Equipment Sizing and Selection and ACCA Manual D Duct Design courses prior to attending this class. This class will step beyond the introduction to ACCA Manual D to more advanced topics, including how to perform Manual D calculations both manually and using the official Wrightsoft ACCA computer software program.
This class will be presented using computers for hands-on training. Participants will perform group exercises and have the opportunity to work on individual problems with the instructor’s assistance.
Class topics will cover:
– Homes with multiple HVAC systems.
– Two-story homes with single systems.
– Using the computer program to generate room-by-room load calculations and select HVAC equipment.
– How to use the graphic design module of the computer software, which automatically calculates room-by-room load calculations and provides Manual D duct design.
Many homeowners are considering changing ‘Gas Furnaces’ to ‘Heat Pumps’ to provide residential heating and cooling.
The Training builds upon the ACCA Wrightsoft series and focuses on the Science of correct sizing of Heat pump systems and includes a Wrightoft computer lab portion.
The session builds upon Manual ‘J’ and provides a foundation upon which Manual ‘H’ will be built.
It is recommended that attendees bring their own laptop preloaded with the Wrightsoft Demo software
Class Overview:
This four hour session covers the science and application of airflow principles to the efficient operation of HVAC equipment. Many of the residential systems in California suffer from the inefficiencies caused by high static pressure. Included in this training is a hands-on portion designed to compare various filters, fittings and layout issues that cause high static pressures.
Class Overview: A residential split system air conditioner undergoes its final assembly at the time of installation. An important factor is the amount of refrigerant in the system (commonly referred to as proper charging). Air conditioner energy efficiency suffers if the refrigerant charge is either too low or too high. This training is designed to assist HERS Raters and HVAC technicians to properly perform a Refrigerant Charge verification. This is a Hands-on class with operational equipment. Please feel free to bring your verification equipment.
Class Overview:
This 1/2 day class covers Manual ‘J’ Sizing Introduction Manual ‘J’ Wrightsoft Set-up and hands on training Detailed Cooling Capacity Data Sheets Air Flow Calculation Worksheets
Class Overview:
This 1/2 day class covers Manual S, Sizing of Residential Equipment based on Manual S and the California title 24 Part 6 parameters. Material includes: Reference App JA-II, Various Manufacture Equipment Data sheets, a PowerPoint with a step-by-step work through, and a Wrightsoft Computer element, Other ACCA Approved Software is being brought into the training at this time.
The course covers Basic concepts of duct design. Covers air flow dynamics and static pressures within the systems, defines and explains EL, friction rate, location, throw and spread of grilles, registers and diffusers. Includes a Software portion for Wrightsoft and will include Elite. The information covers efficiencies relating to design, installation as well concepts focusing on delivered efficiencies, operating points, fan and duct curves.
