Abstract: The present application provides a sealing plate assembly and an air conditioner having thereof. The sealing plate assembly includes a first sealing plate and a second sealing plate mounted on one side of the first sealing plate. The two sealing plates can slide relative to each other. There is a sealing plate joint provided with a vent hole mounted on the first sealing plate and located at the end opposite to the end where the second sealing plate slides out of the first sealing plate. A connector is used for connecting the first sealing plate to the sealing plate joint, such that the first sealing plate and the sealing plate joint can rotate relatively by using the connector as the axis. A telescopic sealing plate assembly is formed through a relative sliding of the two sealing plates to adapt to the sizes of different windows.

Abstract: A dewpoint cooler comprises: a first air circuit and a second air circuit coupled thereto via a heat-conducting wall, through which two circuits can flow two media, wherein the second medium contains a gas, heat-conducting wall break-up means for breaking up at least the thermal boundary layer (50), the laminar boundary layer and the relative humidity boundary layer in both media, which break-up means comprise heat-conducting protrusions; wherein the surfaces of said wall and the break-up means are covered with a hydrophilic coating, which can absorb an evaporable liquid, retain it and relinquish it again (100), such that the wetted coating, the heat-conducting surfaces and the break-up means are cooled. A wetting (150) unit for subjecting the secondary medium to wetting by the evaporable liquid such that evaporated liquid entrained by the secondary medium extracts heat from the primary medium via the wall.

Abstract: A water delivering tube having a spray nozzle secured to the front side thereof is detachably disposed in front of a blower so as to eject water therefrom in the form of mist particles. To feed pressurized water to the water delivering tube, a water feeding tube is connected to the water delivering tube. As the blower is rotated, an environmental air is introduced into the interior of a building to be cooled, and subsequently, it is mixed with the mist particles which in turn are vaporized by the latent heat of the mist particles appearing as the foregoing vaporization proceeds. Thus, a large quantity of warm air in the environmental air in the interior of the building can quickly be cooled without any necessity for carrying out heat exchanging.
