Title:
Air conditioner
Document Type and Number:
Japanese Patent JP6336066
Kind Code:
B2
Abstract:
An air-conditioning apparatus including a compressor, a load-side heat exchanger, an expansion unit, and a heat source-side heat exchanger connected to one another via a pipe to allow refrigerant to circulate also includes a gas-liquid separator configured to separate the refrigerant, a bypass pipe connecting between the gas-liquid separator and a suction side of the compressor, a bypass expansion unit provided to the bypass pipe and configured to adjust a flow rate of the refrigerant, a heat source-side expansion unit configured to adjust a flow rate of the refrigerant flowing into the heat source-side heat exchanger, and a controller configured to adjust an opening degree of the bypass expansion unit on the basis of a bypass flow rate of the refrigerant flowing through the bypass pipe calculated from an opening degree of the heat source-side expansion unit, an inflow flow rate of the refrigerant flowing into the gas-liquid separator, and inlet quality of the gas-liquid separator.
