Title: AIR CONDITIONER DEVICE
Abstract:
Provided is an air conditioner device comprising a refrigerant circuit in which a condenser and evaporator are connected by piping, and through which a refrigerant circulates between the condenser and the evaporator. The condenser has a plurality of heat transfer tubes that are disposed in a zigzag pattern, and has refrigerant flow paths that are constituted of a first flow path that guides liquid refrigerant from a heat transfer tube disposed on one outside row to a heat transfer tube disposed on another outside row, and a second flow path that guides the liquid refrigerant from the heat transfer tube disposed on the other outside row to the heat transfer tube disposed on the one row. Among the flow paths, the first flow path and the second flow path are formed alternately from the inlet formed at the top stage heat transfer tube to the outlet formed at the bottom stage heat transfer tube, and the first flow path and the second flow path are inclined downward from the upstream side to the downstream side.
