Title:
REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2015206518
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration device capable of recovering a refrigerant from a heat source unit in which refrigerant leakage occurs, when the refrigerant leakage occurs in either of the plurality of heat source units.SOLUTION: In a refrigeration device in which a plurality of outdoor units are connected in parallel, each outdoor unit has a first accumulator, and a second outdoor unit has a second accumulator. In a leakage machine as the outdoor unit in which refrigerant leakage occurs, a refrigerant in the leakage machine is sucked by driving a compressor and sent to a gas side of an indoor unit, and the refrigerant is condensed in the indoor unit and stored as a liquid refrigerant. In a non-leakage machine as the outdoor unit free from the refrigerant leakage, a liquid refrigerant is accumulated in the accumulator. Thus the refrigerant of the outdoor unit in which the refrigerant leakage occurs, is recovered in the outdoor unit free from the refrigerant leakage and the indoor unit.
