Abstract
A method for monitoring refrigerant in a refrigeration system includes calculating a saturation temperature of refrigerant in a refrigeration system based on at least one of a discharge pressure and a discharge temperature of the refrigeration system; calculating an expected refrigerant level based on the saturation temperature; comparing the refrigerant level with the refrigerant level threshold; and generating a leak notification when the receiver refrigerant level is less than the refrigerant level threshold. The method may be executed by a controller or stored in a computer-readable medium.
