Carmel Software is pleased to announce that it has released a brand new HVAC refrigerant charging app for Android-based phones. The HVAC Refrigerant Charge (Android Edition) application allows users to calculate superheat and subcool temperature differences for over 75 different refrigerants.

It also includes the following features:

  1. Perform superheat refrigerant charge calculations for 75 different refrigerants. Input the indoor wet-bulb and outdoor dry-bulb temps. to get the target superheat temperature. Then, specify the suction line temperature and pressure to get the actual superheat temperature. The difference tells you whether to charge or not.
  2. Perform subcool refrigerant charge calculations for 75 different refrigerants. Input the indoor wet-bulb and outdoor dry-bulb temps. to get the target subcool temperature. Then, specify the liquid line temperature and pressure to get the actual subcool temperature. The difference tells you whether to charge or not.
  3. Use an interactive slider control to increase or decrease all values and immediately observe calculated results. Also, the slider control allows for "incremental" changes so you can ever-so-slightly change values to observe newly calculated results.
  4. Specify atmospheric pressure (other than standard 14.7 psi) so that calculated pressures are adjusted for high elevations like those in Denver and elsewhere.
  5. Customize input types so that you can specify manufacturer-specified target superheat/subcool or input indoor dry-bulb/indoor relative humidity in place of indoor wet-bulb temperature.
  6. Send an email of all inputs and results with custom message
  7. Display input and result values in either English or Metric units
  8. Change the color scheme of the app so that it can easily be viewed outdoors in direct sunlight
  9. It is "Bluetooth aware", meaning that it will connect via Bluetooth to those PT gauges that are also Bluetooth enabled. This will allow the automatic transfer of temperature/pressure information from those gauges to the HVAC Refrigerant Charge app.
"We recently released this app onto the Android Marketplace, and the response has far exceeded our expectations. It could potentially be our best-selling Android app yet. This tells me that HVAC technicians are not content with the current crop of HVAC refrigerant charging apps that already exist. Instead, technicians are really looking for a simpler, yet more powerful app from a reputable and established company like ours," says Stephen Roth, PE, Principal of Carmel Software.
