PROBLEM TO BE SOLVED: To provide an air conditioning convection flow circulation acceleration device capable of reducing a heating cost by mixing and agitating high temperature air staying in a house ceiling part and low temperature air in a lower part so as to circulate upper and lower convection currents to average the temperature difference.SOLUTION: A suction port 8 is provided bent rearward of the house at lower ends of an introduction pipe 1 having a blower 4 and falling down from a fork branch connection 10； a rear end part of the introduction pipe 1 is inserted from a high temperature air suction port 5 of a mixer tube 2 with a larger diameter； and the introduction pipe 1 and the mixer tube 2 are connected by a plurality of revolving plates 7 obliquely provided in air gap. A rear end part of the mixer tube 2 is inserted from a secondary air suction port 5a of a second mixer tube 2a with a larger diameter； similarly, the first mixer tube 2 and the second mixer tube 2a are connected by a plurality of revolving plates 7a obliquely provided in air gap； and an air outlet 9 is provided bent forward of the house at lower ends of a delivery pipe 3 connected to the second mixer tube 2a and falling down from a fork branch connection 10a.SELECTED DRAWING: Figure 1【課題】 ハウス天井部に滞留している高温空気と下部の低温空気とを、混合撹拌して上下対流と循環をさせて温度差を平均化し、暖房費を削減する空調用対流循環促進装置。【解決手段】 送風機４を備えた導入管１の二股分岐部１０から立ち下げられたそれぞれの下端をハウス後方に屈曲して吸引口８を設け、導入管１の後端部をより大きな径の混合管２の高温空気吸引口５から挿入し、空隙部に斜設した複数枚の旋回板７で導入管１と混合管２とを接続する。 混合管２の後端部をより大きな径の第二混合管２ａの二次吸引口５ａから挿入し、同様に空隙部に斜設した複数枚の旋回板７ａで第一混合管２と第二混合管２ａとを接続し、第二混合管２ａに接続された吐出管３の二股分岐部１０ａから立ち下げられたそれぞれの下端を、ハウス前方に屈曲して吹出口９を設ける。【選択図】 図１
