<p>A screw refrigerating apparatus (1) comprising a refrigerant circulating passage (I) including a screw compressor (11), a condenser (12), an expansion valve (13), and an evaporator (14) is constituted such that a bypass flow passage (II,III,IV) branching at a part of the refrigerant circulating passage (I) between the condenser (12) and the expansion valve (13), routing through throttle means (15,22,58,59), and communicating with a rotor cavity within the screw compressor (11) is provided. The screw refrigerating apparatus (1) is capable of simplifying the structure, decreasing the size, decreasing labour of the maintenance, and the like. <IMAGE></p> |
