Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/106755
Kind Code:
A1
Abstract:
This air conditioner has a refrigeration cycle which circulates a refrigerant and in which a compressor, a four-way valve, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger are connected in this order to refrigerant piping. The outdoor heat exchanger is provided with: a plurality of heat conducting fins; heat conducting piping having a plurality of paths; a distributor for branching a refrigerant path into an upper path and a lower path of the heat conductive piping; a first temperature detection means for detecting the temperature of the refrigerant merged via the distributor; a second temperature detection means for detecting the temperature of the refrigerant passing through the lower path; and a control unit which performs a control for ending a defrosting operation when the refrigerant temperature detected by the first temperature detection means reaches a first target temperature and the refrigerant temperature detected by the second temperature detection means reaches a second target temperature during the defrosting operation.
