Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2023017009
Kind Code:
A
Abstract:
To provide a refrigeration cycle device for increasing the evaporation capacity of a utilization side heat exchanger even when the temperature of refrigerant cannot be sufficiently reduced with the pressure of the refrigerant reduced by an expansion mechanism.SOLUTION: In a main refrigerant circuit (20) where main refrigerant circulates, a main expansion mechanism (27) is provided. A sub refrigerant circuit (80) other than the main refrigerant circuit (20) is provided where sub refrigerant circulates. A sub utilization side heat exchanger (85) provided in the sub refrigerant circuit (80) for functioning as a vaporizer for sub refrigerant is allowed to function as a heat exchanger for cooling main refrigerant flowing between the main expansion mechanism (27) and main utilization side heat exchangers (72a, 72b).SELECTED DRAWING: Figure 1
