Title:
EXPANDER INTEGRATED COMPRESSOR AND REFRIGERATING DEVICE
Document Type and Number:
Japanese Patent JP2022127470
Kind Code:
A
Abstract:
To provide an expander integrated compressor having improved durability.SOLUTION: An expander integrated compressor 100 comprises a rotating shaft 120, a compression mechanism 102, an expansion mechanism 104, a heating element 124, and a temperature sensor 140. The compression mechanism 102 compresses a refrigerant. The expansion mechanism 104 comprises a first gas bearing 118 supporting the rotating shaft 120, and a turbine wheel 105 attached to the rotating shaft 120. The expansion mechanism 104 is connected to the compression mechanism 102 via the rotating shaft 120, and expands the refrigerant. The temperature sensor 140 detects temperature of the first gas bearing 118 or temperature around the first gas bearing 118. The heating element 124 heats the first gas bearing 118 depending on a detection result of the temperature sensor 140.SELECTED DRAWING: Figure 1
