About this app

Instant mobile refrigerant charge calculator for HVACR applications.

The HVACR Check & Charge™ mobile app from Emerson Climate Technologies provides an on-site refrigerant charge calculator for air conditioning and refrigeration applications. Based on historic sliding cardboard charge calculators, this app allows contractors to easily calculate the ​correct system refrigerant charge for R-22, R-410A, R-32, R-407C, R-134a, R-452B, R-454B, R-438A, R-422B, R-427A, R-421A, R-404A, R-290, R-449A, R-448A, and R-407A. Contractors can simply choose Superheat, Subcooling, or Airflow and enter the specified system temperatures along with the latent and sensible environmental loads. These values are then used to determine the proper system charge and whether the charge amount needs to be altered based on these conditions.

• AC & Refrigeration Systems
• Superheat Calculator (non-TXV)
• Subcooling Calculator (TXV)
• Airflow Calculator
• PT Charts (Pressure / Temperature)
• Find a Superheat target using psychometric calculations
• For use with R-22, R-410A, R-32, R-407C, R-134a, R-452B, R-454B, R-438A, R-422B, R-427A, R-421A, R-404A, R-290, R-449A, R-448A, and R-407A
• Imperial and Metric Support

Assists with calculating proper system refrigerant charge based on operating conditions.

Great resource. A little cumbersome to use sometimes, because looking up recommended superheat requires entering system values too. When ambient values change, you have to reenter all the parameters. A little annoying, but still workable. Overall the app is very helpful. Edit: used it again on my R22 system. Airflow is another great feature. You can really tune up the whole system with this app. Raising my rating from 4 to 5 stars. Hard to find this data elsewhere. Thanks a lot developers.

Great app 5 stars. But even with five stars there's always room for improvement. I'm an HVAC tech, an located in the deep south (New Orleans area) which equals high temperatures with high humidity. I have noticed on several occasions the highest dry bulb temperature I can select was 95 degrees it gets hotter than that here. Also when doing superheat, sometime I cannot set the proper wet bulb temperature that I actually have with the pressure that I have. I will have to raise the actually temper

I absolutely love this software, it is extremely extremely easy to use and I tell technicians and installers to download it so we don't have to worry about referencing a charge chart for superheat. I also LOVE that the interface changes the range and available number of temperature options and just doesn'taleays have the same values.. (i.e. if you select 50 degree indoor wetbulb, it only gives you 2 options for outdoor dry bulb 55 and 60 degrees) AND says to not charge at low temps, etc. LOVE IT
