HVACR Check & Charge vs. HVAC School Utilizzo e statistiche
Instant mobile refrigerant charge calculator for HVACR applications.
The HVACR Check & Charge™ mobile app from Copeland 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, R-407A, R-600, R-600a, R502, R-514A and R-515B. 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.
