INDOOR UNIT FOR AIR CONDITIONING DEVICE

摘要

An indoor unit for an air conditioning device is provided with a case, an air delivery fan received in the case, and a heat exchanger unit installed surrounding the air delivery fan and exchanging heat between a refrigerant and air. The heat exchanger unit has: a plurality of heat transfer pipes extending in the vertical direction and forming a plurality of refrigerant flow passages in the width direction of the case and in the air flow direction; and a plurality of headers connected to the opposite ends of the plurality of heat transfer pipes and allowing a refrigerant to flow between the plurality of heat transfer pipes. The plurality of headers includes: a plurality of divided headers to which the plurality of heat transfer pipes in the air flow direction is connected in a divided state, and to which the plurality of heat transfer pipes in the width direction is connected in parallel; and a return header to which the divided refrigerant flow passages in the air flow direction are connected after being turned back and to which the plurality of heat transfer pipes in the width direction are connected in parallel.
