Carmel Software announces that it has developed a customized mobile iPhone application for Johnstone Supply called the Johnstone Toolkit. Developed for Apple's iPhone, iPod touch and iPad, the Johnstone Toolkit app allows users to perform a number of HVAC-related functions, including:

  1. Duct Sizer: This module allows the user to quickly size one HVAC duct run or a range of duct sizes.
  2. PT Chart: This module is an electronic pressure-temperature (PT) lookup chart that allows the user to specify the exact refrigerant temperature/pressure value and view the corresponding pressure/temperature result. It also displays a complete list of pressure/temperature values in 1 degree increments for over 70 different refrigerants. The user can adjust the elevation so proper gauge pressures are displayed.
  3. Capillary Tube Calculator: This module allows the user to perform a capillary tube sizing lookup based upon HP, condenser cooled type, and refrigerant type inputs.
  4. Store Locator: This module allows the user to find the closest Johnstone Supply store to where the user is currently located. The user can also type in a zip code to find all Johnstone Supply stores within a certain radius.
  5. AC/Gas Furnace Efficiency Savings Calculator: This module allows the user to quickly calculate the energy savings for installing a new AC unit or furnace based upon selecting the old/new unit efficiency information and the weather region.
The Johnstone Toolkit app can be downloaded for free from Apple iTunes.

"We are proud to have developed such a versatile mobile application for Johnstone Supply. This app is perfectly suited for the mobile environment allowing engineers to perform quick field-based calculations," says Stephen Roth, Principal of Carmel.
