## What is PsychroFlow Pro?

Elevate your HVAC diagnostics with PsychroFlow Pro, the premium calculator designed for field technicians and engineers.

Start figuring out "what's happening inside the duct" with laboratory-grade precision. PsychroFlow Pro replaces your old charts and slide rules with a modern, dark-mode interface that works perfectly in dimly lit plant rooms.

KEY FEATURES:

1. Advanced Psychrometric Analyzer

Visual Chart: See your air state plotted in real-time on a dynamic Psychrometric Chart.
Solve Any Scenario: Enter any two variables (Dry Bulb, Wet Bulb, Relative Humidity, or Dew Point) to calculate the rest.
Detailed Results: Instantly get Enthalpy, Humidity Ratio (Grains/lb or g/kg), Specific Volume, and Vapor Pressure.
2. Smart Target Charge (Superheat)

Fixed Orifice Logic: Determine the target superheat based on indoor and outdoor conditions.
Built-in PT Chart: No more flipping between apps. Enter your Gauge Pressure (PSI/kPa) and let the app calculate Saturation Temperature automatically.
Multi-Refrigerant Support: R-410A, R-22, R-32, R-407C, R-134a included.
Diagnostics: Get instant "Add Charge," "Recover Charge," or "System OK" recommendations.
3. Mixed Air Calculator

Precise Mixing: Calculate the resulting temperature and enthalpy when two air streams combine. Perfect for diagnosing economizers and fresh air intakes.
4. Professional Grade

Unit Conversion: Toggle seamlessly between Imperial (IP) and Metric (SI) units with one tap.
Offline First: Zero dependency on the internet. Calculations happen locally on your device.
Dark Mode: A "Gold & Glass" aesthetic designed to be easy on the eyes.
Why PsychroFlow Pro? Calculations are based on ASHRAE 2021 Fundamentals formulas for maximum accuracy. Whether you are balancing a commercial layout or charging a residential split system, trust the math behind the tool.
