The "HVAC Psychrometric Plus" app is the #1 selling psychrometric application for the Apple iPhone and iPad. Thousands of happy users have downloaded this useful application for performing quick and simple psychrometric analysis. Just a few reasons why you should buy this application:
1. The Psych Plus is a universal app that it is optimized for the iPhone and iPad.
2. This app was developed by Carmel Software, a company that has been developing software for 25+ years. We are experts in software design and HVAC analysis.
3. It allows you to easily perform single-state and mixed-air HVAC psychrometric calculations.
4. Select and update all input parameters and view the calculated results all in the same screen without switching from one screen to another.
5. Select from 23 different combinations of any 2 input parameters such as "Humidity Ratio / Dewpoint Temperature" and much more.
6. Immediately view updated results as you change the input values using the on-screen slider control. You can specify how much to increase or decrease values as you slide the indicator along the slider mechanism.
7. Send an HTML email and a spreadsheet attachment of all of the single-state and mixed-air inputs and results
8. This app now includes the HVAC Equipment Locator. Click here for details: http://bit.ly/1yTq539
This application contains two separate input modes. The 1st input mode is the "Single-State" mode that 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 23 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 23 combinations of the 2 input parameters and view all results in one screen.
The following input and output value-types are displayed:
1. Dry-bulb temperature
2. Humidity ratio
3. Relative Humidity
4. Wet-bulb temperature
5. Partial pressure
6. Enthalpy
7. Specific volume
8. Dewpoint temperature
9. Total airflow or mass flow (for mixed-air calcs, only)
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.
The "HVAC Psychrometric Plus" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our analysis software and incorporated it into their leading Autodesk Revit software product. In addition, ASHRAE has hired Carmel Software to develop custom mobile apps to accompany their various standards.
We also offer the following apps for the iPhone/iPad:
1. HVAC Residential Load Calcs
