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. \n\n• AC & Refrigeration Systems\n• Superheat Calculator (non-TXV)\n• Subcooling Calculator (TXV)\n• Airflow Calculator\n• PT Charts (Pressure / Temperature)\n• Find a Superheat target using psychometric calculations\n• 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, R-407A, R-600, R-600a, R502, R-514A and R-515B.\n• Imperial and Metric Support\n\nAssists with calculating proper system refrigerant charge based on operating conditions.\n\nInformation on this and other Copeland applications are available at https://www.copeland.com/en-us/tools-resources/mobile-apps","facts":{"developer_id":464252882,"developer_url":"https://www.copeland.com/en-us/tools-resources/mobile-apps","first_released":"2012-12-07T17:03:15Z","support_url":null,"privacy_url":null,"website_url":null,"app_version":"26.8.1","release_notes":"IMPORTANT: Check & Charge has moved to Copeland Mobile.
