摘要

PURPOSE: An oxygen exhaust pipe installation structure of an indoor unit for an air conditioner is provided to supply delightful air to a space for air conditioning and to properly mix oxygen with air supplied to the space for air conditioning. CONSTITUTION: An oxygen exhaust pipe installation structure of an indoor unit(90) for an air conditioner includes a cabinet(100) having various components including a heat exchanger(140) in which heat exchange with an actuating fluid and air of a heat exchange cycle is executed; an oxygen feed pipe transmitting oxygen produced from the outside of the cabinet to the inside of the cabinet; and an oxygen exhaust pipe(150). In the oxygen exhaust pipe, one end through which oxygen is exhausted is arranged around the heat exchanger and the other end into which oxygen flows is connected to the oxygen feed pipe. Heat exchanger brackets(148) are installed to fix the heat exchanger to the inside of the cabinet. A part of the oxygen exhaust pipe is fixed to the heat exchanger brackets in making manufactures.
