    摘要: A refrigerant distributor of a refrigerating cycle for a heat pump of the present invention comprising a compressor for compressing a refrigerant and discharging the refrigerant variably, a distributor for distributing the refrigerant passed through an expansion device expanding the refrigerant to a plurality of branching pipes and making the refrigerant flow to a evaporator including a plurality of blocks, a refrigerant flow controller installed on a certain branching pipe of the distributor for opening/closing the flow of the refrigerant to the branching pipes, and a by-pass pipe for making a certain amount of the refrigerant discharged variably from the compressor flow to the refrigerant flow controller by connecting the discharge side of the compressor and refrigerant flow controller so as to open/close the certain branching pipe of the distributor by the operation of the refrigerant flow controller in accordance with the discharge compressor of the refrigerant discharged variably from the compressor is capable of improving the capability of the evaporator and efficiency of the refrigerating cycle by preventing too much the rise of the evaporation temperature of the refrigerant by using the evaporation region of the external heat exchanger (performing the function of the evaporator in the heating operation) corresponding to the discharge quantity of the refrigerant discharged variably from the compressor.
