Abstract (en)
In an air conditioner (1), refrigerant circulates sequentially through a compressor (10), a condenser (40/20), an expansion device (30), and an evaporator (20/40) in this order during an operation. The condenser (40/20) includes: a first heat exchange portion (40A/20A) and a second heat exchange portion (40B/20B) that are configured such that refrigerant in the first heat exchange portion flows in parallel with refrigerant in the second heat exchange portion; a flow rate restricting portion (34/32) configured to cause a flow rate difference between a flow rate of the refrigerant passing through the first heat exchange portion (40A/20A) and a flow rate of the refrigerant passing through the second heat exchange portion (40B/20B). The air conditioner (1) includes a controller (200) configured to control the compressor (10) and the flow rate restricting portion (34/32). When the controller (200) changes an air conditioning capability of the air conditioner (1), the controller (200) uses a combination of a frequency of the compressor (10) and the flow rate difference between the refrigerants passing through two heat exchange portions.
