摘要： A multistage centrifugal compressor includes a rotary shaft, and multistage impellers attached to the rotary shaft. Each of the impellers includes a hub, a shroud and blades therebetween in a radial cascade arrangement. An annular suction passage for guiding the fluid flow from the inward radial direction to a blade inlet is disposed upstream of the centrifugal impeller. A diffuser is disposed downstream of the centrifugal impeller. A bend portion is disposed downstream of the diffuser, and a return channel with a guide blade portion is disposed downstream of the bend portion. The annular suction passage at a hub side includes an axial parallel portion.

摘要： In a heat pump system including a water purifier and an evaporator for evaporating feed-water to produce steam, water used for spray cooling is effectively used and productivity of purified water used for the spray cooling is increased.Discharged water from the water purifier is supplied to the evaporator when water used for spray cooling is produced by use of the water purifier. Otherwise, drain of the evaporator having higher temperature is supplied to the water purifier by using such a fact that in a reverse osmosis membrane type water purifier, the higher the temperature of feed-water is, the higher the purified water productivity becomes.
