Document Type and Number:
Japanese Patent JP5463995
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-room type air conditioning device capable of preventing inflow of a liquid refrigerant to a compressor when operating load at an indoor unit side is reduced, without increasing the size of an accumulator.SOLUTION: When the operating load at the indoor unit 4 side is reduced by a prescribed range or more, one constant-capacity compressor in the compressors 121, 221 of the outdoor units 2, 102, 202 is operated without reducing the number of operating outdoor units at once according to the reduction of the load, and the operation is executed so that an operating capacity of a capacity-variable compressor becomes minimum in the compressor 21 of the outdoor unit 2. As the number of operating outdoor units and constant-capacity compressor is reduced after the operation is performed in a refrigerant distribution mode for dispersing the refrigerant to the outdoor units 2, 102, 202, the indoor units 4 and the like configuring the refrigerant circuit 10, the concentration of the refrigerant to the operating outdoor unit can be prevented, and the inflow of the refrigerant to the compressor can be prevented without increasing the size of the accumulator.
