Field practitioners from Interplay and BPI have brought together this exciting introduction to Worst Case Depressurization. Proper ventilation is an important aspect of HVAC vitally important when carbon monoxide levels or CO levels reach unacceptable levels due to naturally occurring spillage and draft compounded by depressurization that exceeds recognized limits. In this video and simulation course we will simulate the steps involved in conducting a Worst Case Depressurization measurement part of a larger Combustion Safety Test specifically ANSI BPI and ACCA Standard 12 Home Evaluation and Performance Improvement and other coursework. You'll finish with a challenge simulation to find the Worst Case Depressurization measurement for a new house.

This course covers SEER2 what it is and why it's relevant as well as going over the various common energy efficiency terminology. We will also look at energy use labels as well as the different requirements for each individual region.

This course explores the various parts commonly needed during the cooling season for an HVAC system. This includes an introduction to cooling motors along with the major components of cooling systems.

Heating and cooling load calculations ensure that homes have the correct size of HVAC equipment. The Manual J formula has been used to calculate residential loads for decades. Technicians note characteristics of the house and plug them into a formula. They used to spend a lot of time plugging numbers into equations and solving them. In recent years Manual J software has eliminated the need for human math. In this course we'll use Interplay Learning's 3D simulation technology to perform residential load calculations. We'll calculate the conductive convective and latent loads of three houses. We'll identify the measurements and formulas required to calculate the heat gain and heat loss in BTUs. We'll define each house's thermal envelope. We'll measure the surface area U-value and design temperature difference. We'll check for insulation and find the R-value of the insulation. We'll check for air leakage around the thermal envelope and duct work. Finally we'll put all these numbers into Manual J software and let it calculate the load for us.

In this course technicians will embark on the intricate world of HVAC formulas a foundational knowledge base for technicians seeking to elevate the efficacy of their heating and cooling services. This course covers the formula for clocking a gas meter honing the ability to precisely assess gas consumption. The learner will extend their expertise to air conditioning with the temperature rising method computing CFM for gas and electric units. Beginning technicians will learn to navigate the psychrometric chart to master calculating total heat a cornerstone of efficient HVAC system design. Learners will explore the calculations for sensible and latent heat and understand the precise measure of moisture extracted from the air using the latent heat removal formula. This course will ensure technicians master the calculations essential for optimizing systems and enhancing indoor comfort.
