Instant mobile refrigerant charge calculator for HVACR applications.
The HVAC Check & Charge mobile app from Emerson Climate Technologies provides an on-site refrigerant charge calculator for air conditioning 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, and R-438A. Contractors can simply choose Subcooling, Superheat, 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.
