The "HVAC Pipe Sizer - Liquid" application allows you to quickly size a simple pipe system by inputting a number of piping and liquid properties, including hot and chilled water (hydronic).

You can specify the total fluid flow in GPM (or L/s) and one of either unit head loss (ft/100ft), pipe internal diameter (inches) or fluid velocity (ft/s) parameters. The results include both the exact and nominal pipe diameters and the calculated velocity and total head loss. If you are analyzing an existing pipe system, there is an option to input the existing pipe internal diameter and one of either unit head loss or fluid velocity parameters to derive the calculated fluid flow and other remaining properties.

You can specify additional parameters such as the type of liquid, various properties of the liquid, the pipe material type, the total length of pipe, quantities for up to 11 different types of pipe fittings, and much more. You can also choose to display values in either english or metric units.

This application includes built-in pipe fitting equivalent length and nominal pipe sizing tables for a wide variety of pipe material types and diameters.

This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. You can also manually input exact values.

Lastly, you can email inputs and results to any email address.

This application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit.

The "HVAC Psychrometric" app is a new psychrometric analysis app for the Android OS. It is based upon the #1 selling psychrometric application for the Apple iPhone and iPod touch. Thousands of happy users have downloaded the iPhone version for performing quick and simple psychrometric analysis. Just a few reasons why you should buy this application:

1. This app was developed by Carmel Software, a company that has been developing software for 15+ years. We are experts in software design and HVAC analysis.

2. It allows you to easily perform single-state HVAC psychrometric calculations.

3. Select and update all input parameters and view the calculated results all in the same screen without switching from one screen to another.

4. Select from 23+ different combinations of any 2 input parameters such as "Humidity Ratio / Dew Point Temperature" and much more.

5. 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.

The following input and result 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. Dew Point temperature

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" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. We currently offer 20+ apps for the iPhone and are converting all of them to the Android OS. In addition, we developed the ASHRAE 62.1 ventilation and Duct Fitting Database iPhone apps that are currently sold by ASHRAE, Inc.

The HVAC Duct Sizer app is the #1 selling duct sizing application for the Android OS. Hundreds of users have downloaded this useful application for performing quick and simple duct sizing analysis.


The Duct Sizer application allows you to quickly size one HVAC duct run using the constant friction method. Think of this application as a digital version of the classic Trane Ductulator.

In the "Size by Airflow" mode, you can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensions, the equivalent diameter (for rectangular and oval duct) and the calculated velocity and friction loss.

In the "Size by Dimensions" mode, you can analyze an existing duct system. There are options to input the existing duct dimensions and one of either the airflow or velocity values to derive the calculated duct friction loss.

You can specify additional parameters such as the duct shape (rectangular, round, or oval), the duct material type, duct roughness, the air temperature and the air pressure. You can also choose to display values in either English (IP) or Metric (SI) units.

This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results.

REGARDING THE COMMENT BELOW ABOUT INCORRECT CALCULATIONS: IN FACT, THE CALCULATIONS ARE 100% CORRECT. WE HAVE COMPARED IT AGAINST A STANDARD DUCTULATOR AND ALSO OTHER DESKTOP SOFTWARE CALCULATORS. EVERYTHING IS CALCULATING CORRECTLY. PLEASE EMAIL US AT INFO@CARMELSOFT.COM IF YOU HAVE ANY HESITATIONS.
