HVAC duct calculator for fast, accurate airflow & duct sizing
HVAC Master Toolkit – The Ultimate HVAC & MEP Engineering Suite HVAC Master Toolkit is an all-in-one professional mobile application designed for HVAC Engineers, MEP Consultants, Site Engineers, and HVAC Technicians. Move beyond simple calculations—this comprehensive toolkit provides accurate, real-time engineering solutions for ducting, piping, electrical loads, and psychrometrics, right in the palm of your hand. Whether you are designing in the office or troubleshooting on-site, this app eliminates manual errors, speeds up workflow, and delivers precise results based on industry standards. 🛠️ Key Features & Modules: HVAC Duct Sizer Pro: Easily calculate rectangular and circular duct sizes using Airflow (CFM/CMH), Friction Loss, or Velocity. Features a "Full Analysis" mode displaying Reynolds Number, Friction Factor, and exact air velocity. HVAC Electrical Load Calculator: Quick machine kW and Ampere calculations. Select between DX Units (Split, Cassette, Ductable, Package), VRV Systems, or Chilled Water (CHW) Systems to instantly find Outdoor Unit (ODU) electrical details. McQuay & L&T PipeSizer Pro: Professional pipe sizing module using the Darcy-Weisbach & Colebrook-White equations. Choose materials like Sch 40/80 Steel or Copper Type L to verify fluid velocity and friction conditions. ESP Calc (External Static Pressure): Accurate static pressure calculations to help you select the right fans and blowers for your ventilation systems. Psychro Pro: Access air properties and psychrometric charts on the go for precise cooling and heating calculations. Heat Load Calculator: Quick room cooling and heating load estimations to determine required tonnage (TR). Machine Database: Quick access to equipment weights, dimensions, kW, and Full Load Amps (FLA) for standard HVAC machinery. 📊 Why Choose HVAC Master Toolkit? Comprehensive Suite: No need to switch between multiple apps; get duct, pipe, electrical, and thermal calculations in one place. Industry Standard Algorithms: Built using trusted engineering methods (like Darcy-Weisbach and Colebrook-White). Smart Design Indicators: Visual alerts (e.g., "ACCEPTABLE - Good Design") ensure your calculations stay within safe engineering limits. 100% Offline Capability: Works completely without an internet connection—perfect for basements and remote construction sites. Modern & Clean UI: Features an intuitive interface with Dark Mode support for comfortable viewing in any environment. 📌 Who Is This App For?
