Abstract
Systems and methods are disclosed for detecting a refrigerant charge in a cooling system. The systems and methods involve performing at least a partial pump down of the refrigerant while monitoring one or more metrics. The measured metrics may be compared to a standard in order to determine if a refrigerant leak has occurred or to determine other refrigerant information. Other systems and methods are disclosed.
