PURPOSE:To obtain a pleasant cooling air without disturbing a cooling air zone, by sending waste heat air to a waste heat accumulator by way of a waste heat air suction port and discharging the waste heat air upward behind the top board of a desk from a waste heat air discharge port. CONSTITUTION:When electricity is supplied to a cooling air blasting machine 8, an indoor air is cooled by an evaporator 3, and the cooled air is sent to a cooling air accumulator 9 by way of a cooling air nozzle 13 by the action of a cooling air blower 6. A wind velocity is equalized within the cooling air accumulator 9, where the air is turned into a cooling air, which is sent from an cooling air discharge port 11, thereby forming a cooling air zone above a top board 2. Waste heat air 18 is sent into a waste heat accumulator 10, passing through a waste heat nozzle 17. The pressure of the waste heat air 18 is reduced within the waste heat accumulator 10 and is equalized as the wind velocity is reduced. Then, a unified low speed waste heat air 18 rises naturally from a waste heat air discharge port 15 upward behind the top board 2. It is, therefore, possible to obtain a pleasant cooling air without increasing the cooling air zone above the top board. |
