Attached jet flow constant-temperature dehumidifier for underground building

The utility model discloses an attached jet flow constant-temperature dehumidifier for an underground building. The attached jet flow constant-temperature dehumidifier comprises a case, a constant-temperature dehumidification device, a constant-temperature control device and a jet flow air supply device, wherein the case is provided with a dehumidification area and a jet flow area which are communicated; the constant-temperature dehumidification device and the jet flow air supply device are connected and arranged in the case in a combined operation mode. According to the dehumidifier, the characteristic that the ratio of the specific wall surface to the space of an underground building is very large is utilized, the arrangement mode close to the wall surface is adopted as much as possible,long-distance air supply is achieved in a high-efficiency side wall (or top wall) attaching jet flow mode, the air supply action radius of the dehumidifier is greatly increased, and the narrow and long underground building s
