摘要： A liquid refrigerant discharge pipe extended from a lower portion of a liquid refrigerant storage container (420) communicates with the portion of a liquid refrigerant distributing pipe (421), which comprises both end-closed, substantially one-turn spirally wound pipe, which is in the vicinity of a lower end thereof, and a plurality of discharge holes (426) are provided in an upper wall portion of the liquid refrigerant distributing pipe (421). The diameter of each of the discharge holes (426) is set in accordance with a distance between each hole (426) and the portion of the liquid refrigerant distributing pipe (421) in which the liquid refrigerant discharge pipe communicates therewith, in such a manner that discharge rates of the liquid refrigerant from the discharge holes (426) become equal. When a liquid refrigerant is collected in the liquid refrigerant storage container (420), it flows in the liquid refrigerant distributing pipe (421) from a lower end thereof in the upward direction, and the liquid refrigerant is discharged at such a rate that corresponds to its liquid head pressure. The discharge rates of the liquid refrigerant from the discharge holes (426) become equal, and the liquid refrigerant flows down in a uniformly distributed manner throughout an evaporation coil (41). Since the flow of the liquid refrigerant is uniform, the performance of an evaporator becomes stable.
