The HVAC Toolkit from Carmel Software is the essential app for anyone in the HVAC industry. It includes a combination of most of our individual iPhone applications including:1. HVAC Quick Load2. HVAC Duct Sizer3. HVAC Psychrometric Plus4. Steam Tables5. HVAC Pipe Sizer - Liquid6. HVAC Pipe Sizer - Steam7. HVAC Pipe Sizer - Gas Low8. HVAC Pipe Sizer - Gas HighThe "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 Psychrometric Plus" 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 "HVAC 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 "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 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 developed the ASHRAE 62.1 ventilation app that is currently sold by ASHRAE, Inc.All values can be displayed in English (IP) and Metric (SI) units.We also offer all of the above modules as individual app for the iPhone/iPod touch/iPad:1.
