    Abstract: Disclosed is a framework connecting device of a prefabricated building structure. Each connection portion of frameworks, which are formed in the shape of a square pipe so as to form columns, rafters or the like, is connected and fixed by front and rear connection pieces and a plurality of bolts and nuts which penetrate the same, wherein, during assembly, the frameworks and the front and rear connection pieces are coupled by indented groves and protrusion portions. Base protrusions of the front and rear connection pieces are supported by the frameworks. One or more support pipes which are respectively connected and fixed by bolts and the nuts are provided between the front and rear connection pieces. Therefore, the assembling work may be readily and easily carried out while the strength of the connection portions is being reinforced.

    Abstract: A method for preparing a dehumidifying element including a superabsorbent polymer (SAP) comprises mixing SAP particles with inorganic salt particles, exposing the SAP particles and the inorganic salt particles to a high humidity atmosphere thereby absorbing the deliquescent inorganic salt by the SAP, and drying moisture inside the SAP that has absorbed the inorganic salt. Accordingly, an amount of the inorganic salt absorbed by the SAP is minutely controlled thus to precisely control a degree of an ion exchange therebetween, thereby freely controlling a hygroscopic property of the dehumidifying element including the SAP. Furthermore, since the SAP particles and the inorganic salt particles are physically mixed together, the mixture ratio therebetween is entirely uniform, and therefore, the reliability of the product can be obtained.

    Abstract: A regenerative evaporative cooler, designed to improve the cooling efficiency of its regenerative evaporative cooling unit, is disclosed. In the cooler of this invention, the cooling unit consists of a dry channel and a wet channel arranged to closely come into contact with each other. The dry channel allows primary air to pass through, while the wet channel extracts a part of the primary air from the outlet end of the dry channel so as to form extracted air flowing in the wet channel in a direction opposite to the flowing direction of the primary air. A plurality of cooling fins are arranged in the dry and wet channels to allow the extracted air to come into direct contact with water so as to improve the water vaporization efficiency and the water vaporization area in the wet channel. A first blower fan sucks the primary air into the dry channel, while a second blower fan sucks a part of the primary air of the dry channel into the wet channel so as to form the extracted air. A water supply unit feeds water to the wet channel. In the cooler of this invention, the extracted air flowing in the wet channel absorbs heat from the dry channel by means of the wet channel fin, thus cooling the primary air flowing in the dry channel.
