Test & Balance / Commissioning

The Test & Balance / Commissioning Calculator has some of the most common calculations built in that are used on a daily basis by Mechanical Engineers, Professional Engineers (PE), Commissioning Agents (Cx), Test & Balance Professionals (TAB), Facility Engineering Staff, and HVAC Service Technicians while troubleshooting or checking out HVAC systems.

This Calculator includes the following:

Cooling MBH Calculation: With the known Altitude, CFM, Entering and Leaving Dry Bulb & Wet Bulb Temperatures, this calculator will output the work being performed by the cooling coil in Total, Sensible, Latent MBH, Tons of Cooling and Condensate Gallons per Hour.

Heating MBH Calculation: With the known Altitude, CFM, and Entering & Leaving Dry Bulb, the calculator will give you the Sensible Heating Loads.

Water MBH: With the known GPM and Entering & Leaving Water Temperature, the calculator will give you the amount of heat that is being transferred into the water.

Humidification: With the known Altitude, CFM, Entering and Leaving Dry Bulb & Wet Bulb Temperatures this calculator will output the work being put back into the air stream such as Steam Pounds per Hour, Total MBH and Gallons per Hour added.

Sheave Change: Able to calculate the needed sheaves and belts to increase or decrease the fan RPM to achieve desired CFM. Also calculates required BHP for change, Belt length and gives both Motor Pitch & Fan Pitch Diameter for user preference for which sheave is most desired to change to get to the desired CFM. (Belt length does not work with tensioner or 3 pulley systems)

Traverse Points: Able to put in duct size and note if has an internal liner or not and will output location points to perform traverse in rectangle and round ducts.

GPM: Calculate the GPM based on one of the following combinations:
• Known Cv & ΔP (PSI)
• Known design ΔP of fixed Orifice, Design GPM, Actual ΔP (PSI)
• Known design ΔP of fixed Orifice, Design GPM, Actual ΔP (Ft)

Brake Horse Power: Calculate Brake Horse Power for Single & 3 Phase motors.

Electric Duct Heater: Calculate KW / MBH for Single & 3 Phase Duct heaters based on Amps & Volts.

Psychrometric Properties: Find all the Psychrometric Properties of any known Dry Bulb and Wet Bulb Temperature of Air at any given Altitude.

The Test & Balance / Commissioning App was also featured on HVAC Classes top 15 HVAC Apps. (http://www.hvacclasses.org/blog/useful-apps-for-hvac-techs)
