Document Type and Number:
WIPO Patent Application WO/2020/039692
Kind Code:
A1
Abstract:
This refrigeration cycle device (1) is provided with a refrigerant and a refrigeration cycle circuit. The refrigeration cycle circuit has a compressor (10) and causes the refrigerant to circulate. The refrigerant is an HFO-based refrigerant alone, or is a mixed refrigerant. In the mixed refrigerant, the blending rate of the HFO-based refrigerant is 10 wt% or higher. The compressor (10) has a motor (30). The motor (30) has resin components (31d, 31e, 31f, 31g, 31h). The resin components (31d, 31e, 31f, 31g, 31h) comprise a polyimide having a terminal sealed by a terminal group.
