Main PMRefrigeration Tool page
 
   The first step is to enter your data on this single simple screen.  Every item is a standard measurement that any HVAC/R technician is accustomed to taking.  Altitude and refrigerant are entered on other screens, and are applied in all calculations.            Notice that I have entered actual measurements in this demo, such as 127 volts, 238 volts, 1100 CFM, etc, and not 'nominal values' such as 120 V, 240 V, 1200 CFM, etc.  The purpose of this program is to calculate *actual* system performance, not 'nominal factory specs'.  You already have those from the equipment data.  The point here is to find out 'What it is', so you can compare it to 'What it should be'.
 
    After the entering above, select ' Full report' from the ' Options' drop-down list.  In 2 - 60 seconds, depending on your Palm model ( see FAQ page for time benchmarks and cost comparisons on various Palm models ), you will have the following report in hand ( It is one scrollable report on the Palm. Read the screenshots here from left to right ).
  
              
              
    
   An analysis report similar to the following, showing 'exceptions to normal parameters and results' conditionally based on your data and the calculations and report above, is also now ready for you on your Palm, under the 'Analysis' option.  Over 30 system characteristics are analyzed and reported as needed.
