1. A refrigerant control system, comprising:
a charge module configured to:
determine an amount of refrigerant that is present within a refrigeration system of a building based on a volume of a first heat exchanger located outside of the building, a volume of a second heat exchanger located within the building, and a volume of refrigerant lines of the refrigeration system; and
determine the volume of the first heat exchanger based on at least one temperature of the refrigerant within the refrigeration system, at least one pressure, and a volumetric flow rate of a compressor of the refrigeration system;
a leak module configured to diagnose that a leak is present in the refrigeration system based on the amount of refrigerant; and
at least one module configured to take at least one remedial action in response to the diagnosis that the leak is present in the refrigeration system.
