Title:
REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2015206517
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 liquid-side cutoff valve and a gas-side cutoff valve. A low-pressure communication pipe connects downstream sides of accumulators at a suction side of a compressor of each outdoor unit. In the outdoor unit in which refrigerant leakage occurs, the liquid-side cutoff valve and the gas-side cutoff valve are closed, and an operation of the compressor is stopped, and in the outdoor units free from the refrigerant leakage, the compressor is driven in a state of keeping a four-way switch valve in a cooling operation state, thus the refrigerant of the outdoor unit in which the refrigerant leakage occurs, is recovered.
