An refrigerant accumulator ( 18 ) comprises a first chamber ( 30 ), a second chamber ( 32 ), a pre-evaporator line ( 34 ), a post-evaporator-inlet line ( 36 ), and a post-evaporator-outlet line ( 38 ). The chambers ( 30, 32 ) are in a pressure-isolated arrangement and a heat-transfer relationship. The pre-evaporator line ( 34 ) passes through and communicates with the first chamber ( 30 ). In a steady state, the pressure of fluid in the first chamber ( 30 ) is greater than the pressure of fluid in the second chamber ( 32 ), but their temperatures are the same, and the pressure of fluid within the first chamber is balanced with the pressure of fluid within the pre-evaporator line. In a starved or flooded state, temperature differentials between the chamber ( 30 ) and chamber ( 32 ), and pressure imbalances between the chamber ( 30 ) and the pre-evaporator line ( 34 ), adjust the charge of refrigerant fluid to return the system to a steady state.
