Abstract
An excess liquid refrigerant accumulator for multievaporator refrigeration systems is provided. Under some operating conditions, the lowest temperature evaporator of a multievaporator system may discharge some liquid refrigerant rather than only vapor refrigerant. This liquid discharge creates a loss of cooling capacity. A receptacle connected to the exit of the lowest temperature evaporator accumulates the liquid. By locating the receptacle within the cooled compartment, the cooling capacity which would otherwise be lost, is regained.
