摘要： In a refrigeration station comprising a plurality of compressor (14) arranged in parallel and fixed to a base frame (16) a large-diameter induction manifold (17) is provided which is connected to each compressor casing at such a height as to maintain a constant level of lubricating oil inside the casings. The oil recovered by an oil separator (28) is directly re-emitted through a connecting pipe (33) in the inside of the induction manifold (17) and this pipe (33) is connected to a heat exchanger (34). Apart from performing the function of an inlet manifold, the large-diameter induction manifold (17) also performs the functions of equalizing the coolant fluid and lubricating oil and the function of an actual oil reserve.
