Description

  The present invention is designed to keep the room temperature constant by forcing, mixing, and circulating room air in an air conditioner outlet that is buried in the ceiling and blows out temperature-controlled air from an air conditioner, and in a room that does not have air conditioning equipment, or to improve air conditioning efficiency. It relates to an energy-saving air conditioning system.

  Conventionally, it is known to recirculate indoor air in order to keep the indoor temperature constant. Further, a system is known in which air-conditioned air is acquired from a commercial air conditioner, sent to a room not equipped with air-conditioning equipment, and air-conditioned (Patent Document 2).

  The invention described in Patent Document 2 is an air agitating device that is used together with an air duct that sends conditioned air into a room, and includes an air conditioned wind turbine and an indoor fan, and the air conditioned wind turbine blows air from the air duct into the room. The indoor fan rotates with the rotation of the conditioned wind turbine, and is provided so as to be able to blow air to be mixed with the conditioned air downstream of the conditioned wind turbine. This is an air agitating device that can reduce the cost.

  Certainly, the operating cost can be kept low by rotating the air-conditioned wind turbine with the blown air-conditioned air. However, since it is rotated by conditioned air instead of a motor, the conditioned wind turbine does not have a sufficient rotational speed. Therefore, the indoor air cannot be effectively circulated, which is not satisfactory from the viewpoint of equalizing the room temperature.

  Moreover, the 1st cylinder 3 is fitted in the hole drilled in the ceiling material 21a, and the rafter 9 is fixed with the bis | screw 9a etc. in the ceiling material 21a upper part. As a result, the ceiling material 21a is sandwiched between the rafters 9 and the flange 3b, and the air conditioning outlet 1 can be fixed to the ceiling material 21a.

  The second cylinder 4 includes an extension part 4a having a wide indoor side and a cylinder part 4b continuously provided on the upper part of the extension part 4a. The second cylinder 4 secures a space 7 between the frame 2 and the first cylinder 3. The first cylinder 3 is continuously provided. In FIG. 1, the connecting portion provided continuously with the first cylinder 3 is omitted. And the opening 4e and 4d are provided in the frame 2 side and indoor side.

  At the lower end of the extended portion 4a, a protruding portion 4g protruding in the lateral direction is provided to help circulation of room air. At the upper end of the cylindrical portion 4b, an inner protrusion 4c that protrudes inward and adjusts the clearance with the fan motor 5 is provided.

  The guide 6 is connected to the second cylindrical body 4 through a connecting portion 6d, and extends toward the bottom, a plurality of walls 6c, a protruding portion 6b that projects laterally from the bottom of the wall 6c, It consists of an opening and a blower outlet 6a for jetting the mixed air 8 to the bottom, and the direction of the blown mixed air 8 is adjusted. The connecting portion 6d passes the mixed air 8 in a lattice, net, or rod shape.
