Download Rick Karg’s Toolbox of Online Ventilation Sizing and Commissioning Tools for FREE.
These free online tools will allow architects, engineers, ventilation designers and installers to size ASHRAE 62.22013 ventilation, determine the flow rate of existing ventilation equipment, determine the electrical cost of operating ventilation fans, and calculate the heating and cooling costs of running ventilation systems (you will find that most ventilation systems are not costly to operate). Additionally, you can determine the settings for intermittent operation ventilation timers. This tool is used in Rick Karg’s ASHRAE 62.2 Ventilation for Single Family Dwellings course.
Tools Included
ASHRAE 62.22013 Ventilation Tool. This calculation tool handles all the requirements of the 62.22013 Standard, including new and existing buildings, the alternative compliance path, and infiltration credit.
Ventilation Electrical Usage Calculator. Calculate the annual electrical cost of operating a ventilation fan (or any appliance) that is set up for intermittent or continuous use.
Depressurization Analysis Calculator. This “solve-all” calculator allows you to solve for “Building leakage @ 50Pa” (DTL), “Exhaust flow” of existing appliances, or “Depressurization” (combustion appliance depressurization limit). It can also be used for determining flow of a kitchen range hood fan.
Pitot Tube Airflow Calculator. Along with a pitot tube and a digital manometer, this calculator allows you to accurately measure the airflow within a duct 4 inches (10.2 cm) or greater, such as a kitchen range hood or dryer vent.
Advanced Infiltration Calculator. Calculator hourly infiltration for your location and for a selected date range from one to 365 days, and the resulting heating and cooling loads. Additionally, calculate the ventilation load for balanced and unbalanced ventilation.
