摘要： A magnetic refrigerator includes a plurality of magnetic working substances arranged at intervals in a circumferential direction, and a magnetic field application unit that causes a relative movement with respect to the magnetic working substances in the circumferential direction and applies a magnetic field to the magnetic working substances. The magnetic field application unit includes a first member spaced from the magnetic working substances in an axial direction, and first and second magnets that are arranged between the first member and the magnetic working substances and apply a magnetic field so that a magnetic flux flows in an in-plane direction of the magnetic working substances. The first and second magnets can move relative to the magnetic working substances in the circumferential direction. A refrigeration apparatus includes the magnetic refrigerator and a heating medium circuit to exchange heat with the magnetic refrigerator.

摘要： A refrigeration cycle apparatus uses a sensor that measures temperature of a plurality of refrigerant pipes in a contactless manner. A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a heat-source-side heat exchanger, an expansion mechanism, and a use-side heat exchanger are connected in sequence. The refrigeration cycle apparatus includes a temperature detector that detects temperatures at a plurality of points in a contactless manner, and a heat-source-side controller. At least one heat-source-side heat exchanger and the use-side heat exchanger includes a plurality of refrigerant pipes through which refrigerant to be heat-exchanged flows, and a flow rate adjuster. The flow rate adjuster adjusts flow rate of the refrigerant flowing through each of the plurality of refrigerant pipes. The temperature detector detects respective temperatures of the plurality of refrigerant pipes. The heat-source-side controller controls the flow rate adjustment unit based on the temperatures detected by the temperature detector.

摘要： A compressor includes an actuator, a compression mechanism, a drive shaft, a support, a casing, and a welding pin. The drive shaft transmits a driving force of the actuator to the compression mechanism. The support supports a bearing that rotatably supports the drive shaft. The support has at least one hole formed in an outer surface. The casing has a cylindrical shape and accommodates the drive shaft and the support. The welding pin is press-fitted into the hole of the support and is welded and fixed to the casing. A low rigidity region is provided at at least a part of a periphery of an adjacent portion adjacent to the hole of the support. The low rigidity region has lower rigidity than the adjacent portion. The low rigidity region includes a thin portion having a smaller thickness in a radial direction of the casing than the adjacent portion.
