Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075235
Kind Code:
A1
Abstract:
An air conditioning device (1000) comprises a refrigerant circuit (500), and a control device (100) for controlling the refrigerant circuit (500). A condenser (211) includes a first heat exchanging unit and a second heat exchanging unit configured to be capable of allowing a refrigerant to flow in parallel, and a flow rate adjusting mechanism (272) configured to adjust a flow rate of the refrigerant passing through the second heat exchanging unit. The control device (100) is configured to be capable of causing the flow rate adjusting mechanism (272) to reduce the flow rate of the refrigerant passing through the second heat exchanging unit to below the flow rate of the refrigerant passing through the first heat exchanging unit if an operating frequency of a compressor (200) is a predetermined lower limit frequency. The control device (100) is configured to cause the flow rate adjusting mechanism (272) to reduce the flow rate of the refrigerant passing through the second heat exchanging unit if an air conditioning capability of the refrigerant circuit (500) is greater than an indoor load, and then to increase an opening degree of an expansion valve (230).
