About HVAC Toolkit
The HVAC Toolkit app for the iPhone and iPad is the essential app for anyone in the HVAC industry. It includes a combination of many of our stand-alone iOS applications. Individually, the apps cost a total of $70. By purchasing the Toolkit, you pay only $24:
1. HVAC Equipment Locator
2. HVAC PT Chart
3. HVAC Refrigerant Charge
4. HVAC Duct Sizer
5. HVAC Quick Load
6. Psychrometrics
7. Steam Tables
8. Pipe Sizer - Liquid
9. Pipe Sizer - Steam
10. Pipe Sizer - Gas High
11. Pipe Sizer - Gas Low
This is a universal app that works on both the iPhone and iPad.
The "HVAC Equipment Locator" module allows you to track, share, and customize your equipment nameplate and maintenance data. The version here includes the ability to customize your input screens.
The "HVAC PT Chart" module allows you to easily view the pressure-temperature properties of 75 refrigerants. Think of this app as a digital version of the paper PT charts that you may have carried around with you in the past.
The "HVAC Refrigerant Charge" module allows you to perform superheat and subcool refrigerant charge calculations on-the-fly. This app includes pressure-temperature data for over 75 common refrigerants.
The "HVAC Duct Sizer" module allows you to quickly size one HVAC duct run and a range of duct sizes. 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 "HVAC Quick Load" module 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 "Psychrometrics" 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.
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 High/Low" 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 iOS 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.
All of the above modules display units in English or Metric.
Also, all of the above modules allow you to send emails with inputs and results.
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, Carmel has developed customized apps for organizations such as ASHRAE, Mitsubishi Electric, and Pacific Gas and Electric, amongst others.
We also offer all of the above modules as individual apps for the iPhone/iPad:
1. HVAC ResLoad-J

Psychrometric module:
1. The digit separator option now applies to any values greater than 999 such as airflow and elevation (i.e. - if an airflow value for stream 1 is 10,000 CFM and the user of the app is located in Denmark, they can toggle off the "," digit separator so the value displays as 10000 and not 10,000).
Steam Tables module:
1. The max allowable superheated steam pressure is now 15,500 psia.
Duct Sizer module:
1. In addition to performing simple duct sizing, you can now display a range of duct sizes by specifying minimum and maximum friction loss and airflow values.
