The air conditioner null which executes the air conditioning manner and its air conditioning manner of the perimeta area

摘要

PURPOSE:To form an air curtain without using an air conditioning device exclusively for a perimeter zone, and at the same time, improve the temperature environment of the perimeter zone. CONSTITUTION:An indoor unit 38 which is set in a perimeter zone 36 draws air in a room from a suction port 40 and blows up the air from a air outlet 41. Then, the air is discharged from an air discharge duct 39 together with an outside air load. At that time, primary air for an interior zone 31, which is sent out of a branching duct 44, is fed on the downstream side of a fan 43 in an air passage 42. Thus, air which is more than the air drawn from the suction port 40 of the indoor unit 38 is blown out of the air outlet 41, and an air curtain is formed between the air outlet 41 and air discharge port 39. Also, a load (the primary air for the interior zone 31) which stands against the outside air load is added to a circulating flow which circulates between the air outlet 41 and suction port 40 by taking in an outside load, and by doing this, the temperature environment of the perimeter zone 36 is improved.
