Abstract: The disclosed refrigeration-cycle equipment comprises a main circuit and an evaporation-side circulation circuit. The main circuit includes i) a compressor that compresses refrigerant vapor, ii) a condensation mechanism that condenses the refrigerant vapor, and iii) an evaporative mechanism that stores refrigerant liquid and that evaporates the refrigerant liquid. The evaporation-side circulation circuit includes a heat exchanger for heat absorption and a decompression mechanism. The refrigerant returns to the evaporative mechanism after the refrigerant absorbing heat in the heat exchanger for heat absorption and the pressure of the refrigerant being reduced in the decompression mechanism. The refrigeration-cycle equipment further has an interaction mechanism that prevents droplets contained in the refrigerant having returned from the evaporation-side circulation circuit to the evaporative mechanism from being fed into the compressor.

Abstract: A turbo machine of the present disclosure includes a rotation shaft, a first bearing, a casing, an impeller, a first space, a second space, a storage tank, a first outlet passage, a supply passage, a pump, a main passage, and a sub-passage. The second space is in communication with a space formed between a bearing surface of the first bearing and an outer surface of the rotation shaft. The main passage is in communication with the second space and extends in the rotation shaft from an end of the rotation shaft in an axial direction of the rotation shaft. The sub-passage is formed in the rotation shaft and allows communication between the space between the bearing surface of the first bearing and the outer surface of the rotation shaft and the main passage.

Abstract: A turbomachine for a refrigeration cycle apparatus that uses a refrigerant whose saturated vapor pressure is a negative pressure at ordinary temperature includes a rotation shaft and a bearing for supporting the rotation shaft. The rotation shaft includes a lubricant supply passage for supplying the refrigerant as a lubricant that travels smoothly between the rotation shaft and the bearing. The lubricant supply passage includes a main passage and a sub-passage. The main passage extends from an inlet located at an end of the rotation shaft in an axial direction of the rotation shaft. The sub-passage diverges from the main passage and extends to an outlet located in a side surface of the rotation shaft.
