Title:
REFRIGERATING CYCLE
Document Type and Number:
Japanese Patent JP3671850
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerating cycle of high reliability wherein a refrigerator oil is prevented from stagnating inside the cycle even when the refrigerator oil is weakly soluble in a refrigerant and thus exhaustion of the oil of a compressor is prevented, and wherein a large amount of liquid back to the compressor is avoided even when an accumulator is dispensed with, in regard to the refrigerating cycle wherein a surplus refrigerant is brought about.
SOLUTION: A receiver and first and second restrictors disposed before and behind the receiver are provided as equipment for controlling the saturation oil solubility in a liquid refrigerant in the refrigerating cycle, so that the surplus liquid refrigerant brought about in circulation of the refrigerant be collected in the receiver with a high temperature, thereby preventing separation of the refrigerator oil of weak solubility.
