The HVAC Toolkit app for the iPhone is essential for anyone in the HVAC industry. This latest update includes 2 brand new modules, all for the same price. The app includes:
1. HVAC Quick Load
2. HVAC Duct Sizer
3. HVAC PT Chart
4. Refrigerant Charge
6. Steam Tables
7. Pipe Sizer - Liquid
8. Pipe Sizer - Steam
9. Pipe Sizer - Gas Low
10. Pipe Sizer - Gas High
The "HVAC Quick Load" module allows you to quickly calculate total heating and cooling loads for a wide variety of building types.
The "HVAC Duct Sizer" module 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. In addition, you can calculate for a range of duct sizes by specifying minimum and maximum friction loss and airflow values.
The Duct Sizer module also allows you to email an HTML and .CSV (spreadsheet) file with all of the inputs and results.
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 "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 "Psychrometrics" module allows you to easily perform single-state and mixed-air HVAC psychrometric calculations for up to 23 different combinations of input parameters.
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 "Pipe Sizer - Liquid" module allows you to size a pipe run for many different types of liquids (or fluids), pipe material and fitting types.
The "Pipe Sizer - Steam" module allows you to size a steam pipe run, and it also includes a bonus steam table calculator.
The "Pipe Sizer - Gas Low and Gas High" modules 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 apps 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, duct material types, fitting quantities, min and max ranges, and step values.
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.
All values can be displayed in English (IP) and Metric (SI) units.
