The HVAC Professional Formulator includes all 200 formulas of the HVAC Fomulator and adds 18 charts as well the complete International Mechanical Code. A future upgrade free for current users will add the International Energy Code. It is the perfect tool for any Heating Ventilating and Air Conditioning Professional. The Professional Version includes charts from everything from Chimney Clearance to Refrigerant Classification. Sections include: Air Change, Airside, Boilers, BTU Conversions, Ductwork, Energy Values, Heating Design, Heating Requirements, Humidity, Loads, Pumps, Steam, Temperature, Waterside Systems, Conversions and Area Calculations. Heating Designs calculations include formulas such as electric heating calculations, electric baseboard, Heat Tracing Cable, Gas Fired Radiant Ceiling formulas. The program also includes conversions calculations and Area Formulas.
HVAC Professional provides an easy was to quickly find what you need, you can search, mark formulas as favorites, or access recently used formulas. You can also save formula results and e-mail them.
HVAC Professional is the first version of a dynamic program, planned to develop and evolve. It was not our intent to include every possible HVAC formula in this program version. Additional formulas will be added over time. If there is a formula you would like us to add, please contact us and we will do our best to add that formula.
Here is a list of many of the formulas:
