"HVAC Toolkit" for the Apple iPhone/iPod touch

Click here to go to Apple iTunes to download this app.

The HVAC Toolkit application from Carmel Software is the essential app for anyone in the HVAC industry. It includes a combination of all of our individual iPhone applications including:

1. HVAC Quick Load
2. HVAC Duct Sizer
3. HVAC Psychrometric Plus
4. Steam Tables
5. HVAC Pipe Sizer - Liquid
6. HVAC Pipe Sizer - Steam
7. HVAC Pipe Sizer - Gas Low
8. HVAC Pipe Sizer - Gas High

The "HVAC Quick Load" allows you to perform quick and simple HVAC cooling and heating load calculation analysis. You can specify the building type, total area, and # of people. The results include the total cooling and heating loads and airflows.



The "HVAC Duct Sizer" allows you to perform quick and simple duct sizing analysis. 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 and the calculated velocity and friction loss.



The "HVAC Psychrometric Plus" module allows you to easily perform single-state and mixed-air HVAC psychrometric calculations for a wide range of barometric air pressures.





The "Steam Tables" module allows you to calculate the properties of saturated or superheated steam by specifying 2 input properties. This module is also part of the "Pipe Sizer - Steam" module discussed below.



The "HVAC Pipe Sizer - Liquid" module allows you to size a pipe run with many different types of liquids (or fluids), pipe material and fitting types.



The "HVAC Pipe Sizer - Steam" module allows you to size a steam pipe run, and it also includes a bonus steam table calculator.





The "HVAC Pipe Sizer - Gas" module allows you to quickly size a simple low (less than or equal to 1.5 psi) and high (greater than 1.5 psi) pressure gas piping system by inputting a number of piping and gas properties.





This application includes all of the great features of the individual HVAC iPhone applications such as the use of slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. It also allows you to specify different types of liquids, gases, pipe material types, fitting quantities, min and max ranges, and step values. Also, you can display all units in English or Metric.



The "HVAC Toolkit" 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. In addition, ASHRAE has hired Carmel Software to develop custom mobile apps to accompany their various standards.
