Description

Get the number one selling HVAC app for the iPhone - HVAC Buddy. If you are servicing equipment the best way to begin diagnosis and determine the proper refrigerant charge is to use HVAC Buddy, a set of gauges, and a thermometer.

• Superheat for fixed capillary or Subcool forTXV/EXV systems
• Calculates and displays targeted vs. actual Subcooling
• Common refrigerants 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 or Metric
• Use Target Superheat and Subcool tables or enter manually
• Fast! Update values realtime with Temp and Pressure sliders
• User friendly with several pages of step by step instructions

if the early outdoor temperature is 75F and you charge the system to a “beer can cold” suction line your system is likely improperly charged. Later in the afternoon high temperatures will increase head pressure and the resulting overcharge means a lower than desired superheat and wasted energy. Not good!

Summary of Features:

Use HVAC Buddy to enter the type of refrigerant, indoor and outdoor temperatures, and pressures. The math is done for you to display Target, Actual, and Difference. Use the temperature and pressure sliders to see what happens in realtime when these values change. HVAC Buddy contains generic charts for target Superheat and Subcool as well as pressure-temperature tables for R22, R-410A, R-404A, and R-134A. Data in the PT chart is displayed on the refrigerant row and can easily be viewed by moving the pressure slider. Add or recover refrigerant to get the Actual value to within the displayed target Superheat or Subcool range.

Diagnosis tab - shows common causes for high and low superheat, subcooling.

Instructions - Includes several pages of detailed step by step instructions. Use the support system at www.mobileenergyapps.com for questions, comments, or concerns.

New features with release 1.1

Imperial/Metric - View units in Fahrenheit/Celsius or psi/kPa. Buttons at the top of the screen permit toggling back and forth with instant redisplay of values.

Airflow - For cooling, compares a targeted difference across the coil vs. actual. Also called Delta-T or Target Evaporator Exit Temperature (TEET). Sliders change values in realtime.

Email - Use the email tab to create defaults for email addresses, subject, and System Status Report introductory text. Press the email but and these values are incorporated into a formatted page including all the parameters recorded in HVAC Buddy. Edit the email and / or add contacts from your contact list. Then on each call it's just a couple taps to send a personalized report.

"Set Slider" - The slider now can be reset to zero with the Set Slider button. Set Slider updates the base value with the one displayed on the screen. It's now possible to never really have to enter in a number after initial values are set.

Error(s) in Release 1.1
1) Subcooling tab 'discharge' should read 'liquid line leaving' temperature.
