Abstract
A refrigerant system is provided with a method and a control programmed to perform the method, in which a low charge of refrigerant is identified. The mass flow of refrigerant through the system is calculated utilizing at least two different methods. The two calculated mass flow rates are compared, and if they differ by more than predetermined amount, a determination is made that there is a low charge of refrigerant within the system.
