Summary of Features
- The HVAC Psychrometric Plus app is a universal app that works on both your iPhone and iPad and adjusts its screen size accordingly.
- Select from two separate input modes. The "Single-State" mode allows you to specify 2 psychrometric parameters for a single stream of air and view the remaining 6 calculated values. You can quickly toggle through 20 different combinations of the 2 input parameters and instantly view the calculated results, all on the same screen. The 2nd input mode is the "Mixed-Air" mode that allows you to specify 2 psychrometric parameters for each of two air streams to calculate the mixed air psychrometric conditions. Once again, you can toggle through 20 combinations of the 2 input parameters and view all results in one screen.
- You can specify additional parameters such as the altitude of the air being analyzed, the atmospheric pressure, different types of units such as degrees F or R, and English or Metric units.
- Immediately view updated results as you change the input values using the on-screen slider control.
- Email all inputs and results from both the single-state and mixed-air modes along with a spreadsheet attachment.
