Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/009504
Kind Code:
A1
Abstract:
This refrigeration cycle device (100) comprises: a first circulation flow path (L1) by which a compressor (10), a first heat exchanger (20), a depressurization device (30), and a second heat exchanger (40) are connected and in which a first refrigerant is circulated; an accumulator (21); and a heat pipe circuit (50). The heat pipe circuit (50) is provided with a heat-absorbing part (51E), a heat-releasing part (51D), and a fixed-pressure valve (55). A second circulation flow path (L2) is provided with a gas phase flow path (50G) and a liquid phase flow path (50L). The fixed-pressure valve (55) attains a closed state when the pressure of a second refrigerant is equal to or greater than a stipulated value, and attains an open state when the pressure of the second refrigerant is less than the stipulated value.
