HVAC Buddy® 5.0.4
Make your job easier with our handy refrigerant charging anddiagnostic HVAC app - HVAC Buddy®. If you are servicing equipmentthe best way to begin diagnosis and determine the properrefrigerant charge is to use HVAC Buddy, a set of gauges, and athermometer. • Superheat for fixed capillary or Subcool forTXV/EXVsystems • Calculates targeted vs. actual Subcooling • 73refrigerants including R-22 (Freon), R-410A (Puron), R-404A, R-134A• Airflow / Delta-T / TEET Calculation • Diagnosis tab for leaks,overcharge, contaminants, etc. • Email System Status Report •Imperial (IP) or Metric (SI) • Use Target Superheat and Subcooltables or enter manually • Fast! Update values realtime with Tempand Press sliders • User friendly with several pages of step bystep instructions if the early outdoor temperature is 75F and youcharge the system to a “beer can cold” suction line your system islikely improperly charged. Later in the afternoon high temperatureswill increase head pressure and the resulting overcharge means alower than desired superheat and wasted energy. Not good! Features:Use HVAC Buddy to enter refrigerant, temperatures, and pressures.The math is done for you to display Superheat or SubcoolingTarget,Actual, and Difference. Use temperature and pressure sliders to seewhat happens in realtime when these values change. HVAC Buddycontains generic charts for target Superheat and Subcool as well aspressure-temperature tables for 71 Refrigerants. Temperature datafor your pressure is displayed on the refrigerant row and changescan easily be viewed by moving the pressure slider. Add or recoverrefrigerant to get the Actual value to within the displayed targetSuperheat or Subcool range. Diagnosis tab - shows common causes forhigh and low superheat, subcooling. Instructions - Several pages ofdetailed step by step instructions. Imperial/Metric - View units inFahrenheit/Celsius or psi/kPa. Airflow - For cooling, compares atargeted difference across the coil vs. actual. Also called Delta-Tor Target Evaporator Exit Temperature (TEET). Sliders change valuesin realtime. System Status Report - Use the email tab to createdefaults for email addresses, subject, and System Status Reportintroductory text. Tap the email button and these values areincorporated into a formatted page including all the parametersrecorded in HVAC Buddy. Edit the email and / or add contacts. Thenon each service call it's just a couple taps to send a personalizedreport. Note: To access Diagnostics, Email, and Instructions useyour phones menu button. This app does NOT have a traditional PTChart display. However, you can view temperatures in the upper lefthand corner given any vapor line pressure (Superheat tab) or Liquidleaving pressure (Subcooling tab).

HVAC Buddy® Duct Calc 1.3
The best and number one selling duct sizing tool for Androiddevices with thousands of happy users. For less than the cost of acardboard wheel ductulator always have a fast, accurate way toanalyze ducts for design (by Airflow) or existing installations (bySize).Airflow Tab• Calc decimal & rounded sizes for any aspectratio• Solve for Volume, Aspect Ratio, Friction, or VelocitySizeTab• Calc Friction and Velocity given duct sizeSettings Tab:• Entervarious units - Airflow (cfm, m3/s, l/s, m3/hr) Friction (in/100',Pa/30m), Duct Sizing (in, cm), Velocity (ft/min, m/s)• Definestandard air - Altitude (ft, meter), Temperature (Fahrenheit,Celsius), Relative Humidity (pct)• Displays calculated KinematicViscosity (ft2/s) and Specific Volume (ft3/lb)Material Types:• PVC•Aluminum• Galvanized Steel• Spiral Steel• Smooth Liner• FiberLiner• Flex DuctDuct Shapes:• Round• Rectangular• OvalDuct Sizing•Round to Even Units• Round to Odd UnitsCalculations are based onfriction loss equations in the ASHRAE Handbook of Fundamentals2009.Review Notes-----------------------------------------A 12x12duct matches FPM and CFM when friction is ignored which does nothappen in real life. This relationship changes based on theproperties of air (see kinematic viscosity on the settings tab) andon the friction value determined via the type of duct selected.Also, for the times when you want to get friction given CFM andDuct use the "Airflow" tab, select the "ft/min" checkbox and movethe slider accordingly. There are many ways to drive the openvariable.Accuracy:-----------------------------------------Calculationshave been verified against ASHRAE fundamentals and several otherreferences. There are more input criteria (such as duct material)than velocity, friction, and size mentioned in the review which thereviewer may not have taken into consideration.

For this orany app of this nature you must be familiar with and have knowledgeof construction materials and measuring skills to do a loadcalculation. In other words, the data entered must be good andaccurate for meaningful results.Comes with a "Default" projectcontaining all the construction types. Whenever new loads arecreated they may be copied from the Default project or any otherload within the project. Create new Projects by copying from theDefault project or create your own template projects to improveefficiency. Project may be filtered by staus - New, Template,Scheduled, or Complete.Comes with one Example Project in threestages. The first stage "Ex 1 Block" is a simple block loadanalysis with inefficent ducting. The second stage "Ex 1 Blockw/Improved Ducts" shows the improved lower loads resulting fromimprovements in duct sealing as well as moving to R8 material inthe ducts. The third stage "Ex 1 Block w/Rooms" is the same housewith room by room loads.Loads: Above Grade Walls, Basement Walls,Ceilings, Floors, Partition Ceilings, Partition Walls, Doors,Windows, Skylights, Blower Heat, Infiltration, Ventilation, andInternal Gains.Opening Area Calculation: Calculates andautomatically subtracts opening area for walls with attached doorsand windows. In addition, if you elect to specify a wallorientation windows associated with the wall can optionally inheritthe wall orientation.Note: Many features are accessed using yourdevice (phone) Menu key.For more screenshots and information visitthe website at the link provided.Documentation covers creating,copying a new project. Please feel free to use the support link toask any questions on how to use, etc. Your question helps improvefuture documentation updates.If you have any problems with the appplease email support with information describing the issue so thatwe may reproduce the problem and correct.For the fastest responseto questions or support there is a support link from within theapplication or use the support email link from this page.AboutPowertrade--------------------------Powertrade is the number onedeveloper of mobile HVAC apps with professional looking, provenapps in the hands of over 20,000 users worldwide.Powertrade HVACBuddy® Applications:-------------------------HVAC Buddy® Load Calc(Apple) - This app is also available on iOS devices - iPhone,iPadHVAC Buddy® - Refrigerant charging and diagnosticsHVAC Buddy®Duct Calc - Powerful, simple to use real-time interface to help youchoose optimal duct sizesHVAC Buddy® Pressure Temperature -Traditional PT Chart with 71 Refrigerants in Metric or Imperialunits
