HVAC Toolkit Ultimate vs cFormula

This may just be the only HVAC app you will ever need. The HVAC Toolkit Ultimate from Carmel Software is a universal app that works on both the iPhone and iPad. It is the essential app for anyone in the HVAC industry. It is a compilation of most of the individual iPhone and iPad applications offered by Carmel Software plus bonus software. If you bought each of these apps separately, it would cost more than 2 times what the price of this app is. It includes: 1. HVAC Residential Load Calc HD (iPad version) 1. HVAC Residential Load Calcs (iPhone version) 1. HVAC Equipment Locator 2. HVAC PT Chart 3. HVAC Refrigerant Charge 4. HVAC Duct Sizer 2. HVAC Quick Load 6. ASHRAE Ventilation Calcs (iPhone version) 7. Psychrometrics 8. Steam Tables 9. HVAC Pipe Sizer - Liquid 10. HVAC Pipe Sizer - Steam 11. HVAC Pipe Sizer - Gas Low 12. HVAC Pipe Sizer - Gas High The "HVAC Residential Load Calcs" module allows you to perform comprehensive HVAC block and room-by-room load calculations for small commercial and residential buildings. You can easily use this module out in the field by taking advantage of the simplicity and power of the iPhone or iPad, and then email results back to your office. 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 (this is usually an in-app purchase on the free stand-alone version of Locator, but it is included here). The "HVAC PT Chart" module allows you to easily view the pressure-temperature properties of 100 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 100 common refrigerants including azeotropic (bubble/dew) versions of refrigerants. 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 "HVAC Quick Load" module allows you to quickly calculate total heating and cooling loads for a wide variety of building types. 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 "ASHRAE Ventilation Calcs" module allows you to perform comprehensive minimum ventilation calculations for a wide variety of commercial buildings based upon ASHRAE Standard 62.11-2007 and 2010/2013 versions. 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. All values can be displayed in English (IP) and Metric (SI) units. We also offer all of the above modules as individual apps, too.

Customize formulas and calculate at any time. I want to calculate using formulas, but most apps have built-in formulas. There are countless formulas in the world, and it is not easy to find the formula you need to use. Now you can create your own formula within 1 minute. Just 3 steps: 1. Take a photo or select a formula image in the album. 2. Add variables. 3. Enter an expression containing variables. The formula creation is completed, and the calculation is completed instantly by inputting the numerical value of the variable. 【 Main functions 】 ——Take pictures and crop them. ——Select an image and crop it. ——Set formula variables, support uppercase and lowercase letters in English and Latin, and support subscripts. ——A dedicated keyboard for expression input, simple and easy to use. ——Check the expression and prompt for incorrect positions. ——Number specific keyboard, clear and easy to use. ——Supports angle or radian calculation settings. ——Supports calculations such as arithmetic, exponent (power), root, trigonometric function, logarithm, etc. ——Support Scientific notation and factorial calculation. ——Supports constant inputs such as e and π. ——ICloud cloud synchronization creates formulas that are shared across multiple devices and can be used anytime. ——Support restoring after deletion. The deleted formula will be permanently deleted after 30 days. Tip: 1. The simplest formula is to have no images, no variables, and only expressions. You can use it to calculate mathematical formulas with fractions and multiple parentheses. Can be used all at once, next time clear the expression and input a new one. 2. The image of the formula is used to compare the input variable values during use. You can take photos of formulas on books, computer screens, or handwrite them. You can also use other software to edit screenshots of formulas. 3. The dedicated keyboard for expression input is for convenience and ease of use. You can also paste functions that the keyboard does not support in the expression input box, which may bring surprises.
