HVACR Check & Charge 24.5.0

The HVACR Check & Charge™ mobile app from Emerson Climate Technologies is a professional tool that provides contractors with an efficient and accurate on-site refrigerant charge calculator for air conditioning and refrigeration applications. Inspired by the functionality of traditional sliding cardboard charge calculators, this app enables contractors to easily determine the correct system refrigerant charge for a wide range of refrigerants, including 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 have the choice to calculate Superheat, Subcooling, or Airflow and input the specific system temperatures along with the latent and sensible environmental loads. These values are then utilized to determine the appropriate system charge and make any necessary adjustments according to the prevailing conditions.
