Title:
空気調和装置及び熱源機
Document Type and Number:
Japanese Patent JP6391832
Kind Code:
B2
Abstract:
In the present invention, an air conditioner has a heat source device, a plurality of indoor devices, and a relay device connected between the heat source device and the plurality of indoor devices via refrigerant pipelines. A heat-source-side heat exchanger includes an upper-stage heat exchanger and a lower-stage heat exchanger that are connected in parallel to a compressor and disposed so as to be aligned in the vertical direction. The heat source device is provided with: a capacity control valve for controlling the flow of refrigerant into the upper-stage heat exchanger and lower-stage heat exchanger to control the capacity of the heat-source-side heat exchanger; a heat-source-side gas-liquid separator for separating the refrigerant flowing in from the relay device into a gas refrigerant and a liquid refrigerant; a first branch pipeline through which the refrigerant that has flowed into the heat-source-side gas-liquid separator is caused to flow through the capacity control valve; a second branch pipeline through which the refrigerant that has flowed into the heat-source-side gas-liquid separator is caused to flow into the lower-stage heat exchanger; and a flow-rate control device provided to the second pipeline, the flow-rate control device adjusting the rate at which refrigerant flows into the lower-stage heat exchanger via the second pipeline.
