Title:
COMPRESSOR, REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/189315
Kind Code:
A1
Abstract:
Provided is a highly reliable scroll compressor (10). The scroll compressor (10) comprises a case (20), a scroll compressor mechanism (50), a discharge pipe (24), a first temperature sensor (15), and a second temperature sensor (25). The scroll compressor mechanism (50) is arranged inside the case (20), compresses refrigerant that has been sucked in, and discharges the compressed refrigerant to refrigerant flow channels (R1–R3) that are formed in an internal space in the case (20). The discharge pipe (24) allows the compressed refrigerant to flow from the internal space in the case (20) to the outside. The first temperature sensor (15) has a temperature-sensitive part (15a). The temperature-sensitive part (15a) is arranged in refrigerant flow channel (R2) and directly measures the temperature of the refrigerant. The second temperature sensor (25) is arranged in a different location from the first temperature sensor (15) and measures the temperature of the surface of the discharge pipe (24), an internal space in the discharge pipe (24), or the surface of the case (20).
