NEW! V in HVAC – What, Why, Where, How, and How Much (Includes Basics Requirements of Standard 62.1-2022)

Share This

Course Length: 3 hours

This course teaches the basics of the ventilation and provides the current concepts behind the new ASHRAE Standard 62.1-2022, Ventilation for Acceptable Indoor Air Quality. Ventilation (V) is the third leg in the three-legged stool of HVAC. We need heat (H) to stay warm when it is cold outside, and we like air-conditioning (AC) to keep us cool when it is hot outside. What’s about V?  What is ventilation, why do we ventilate, where does ASHRAE Standard 62.1 apply, how must ventilation air be distributed, and how much air do we need?  Topics will include minimum requirements for cleaning outdoor air, designing HVAC systems, determining the ventilation rate quantity, commissioning, and operations and maintenance.

This course focuses on the basic requirements of ASHRAE Standard 62.1-2022 and covers the scope, application, and multiple compliance paths available in the standard, including the ventilation rate procedure, indoor air quality procedure, and natural ventilation procedure. Many of the standard’s general requirements apply regardless of the procedure used. The different application conditions for the ventilation rate procedure are also described, along with changes particular to the 2022 version of ASHRAE Standard 62.1. This course is highly recommended for all HVAC designers and engineers.
