ABSTRACT:
A refrigerant apparatus having an accumulator for receiving binary refrigerant from the evaporator of the apparatus. An expansion valve is connected in parallel with a capillary duct for increasing the refrigerant delivery from a preselected minimum determined by the capillary tube to controlledly flood the evaporator. The lower boiling point component of the binary refrigerant is caused to be separated in the accumulator for delivery to the compressor during flooded operation of the apparatus so as to increase the proportion of the low boiling point component in the binary refrigerant to provide increased refrigeration capacity to meet the increased demand. Upon decrease in the demand, the accumulated liquid refrigerant in the accumulator is gasified for returning the system to the normal ratio of components of the binary refrigerant. The expansion valve is caused to operate as a function of the temperature of the space refrigerated by the evaporator in effecting the desired flooding operation.
