Description

  The present invention relates to an air conditioner, and more particularly, to an adsorption element having functions of heat exchange and adsorption / removal of moisture, odor, harmful gas, and the like.

  A flat sheet and a corrugated sheet are bonded with an adhesive to form a one-wave molded body, and the single-wave molded body is wound with an adhesive to form a substantially cylindrical shape. Since a cylindrical block with a large number of flow paths that are held and surrounded by flat sheets and corrugated sheets can greatly increase the flow area per unit volume, dehumidifying elements and heat exchange elements have this structure. It is manufactured using.

  In the case of a dehumidifying element, the absorption efficiency of the adsorbent per unit volume of the cylindrical block is increased by carrying a hygroscopic material in the flow path of the cylindrical block, and moisture adsorption is achieved by rotating the cylindrical block. And the reproduction is performed continuously.

  In the case of heat exchange elements, the heat exchange rate per unit volume of the cylindrical block is increased by using a cylindrical block with high thermal conductivity, and heat exchange is performed continuously by rotating the cylindrical block. ing.

  Further, when ceramic or the like is used as the material of the cylindrical block, the strength is secured by covering with a frame made of metal or the like to make up the brittleness, thereby forming a cylindrical block body.

  In the case of a dehumidifying element, moisture is moved from the airflow on the processing side to the airflow on the regeneration side while the airflow flowing into the cylindrical block body is separated by the casing, and the exhaust air in the case of the heat exchange element. The adsorption element performs heat recovery from the airflow on the side to the airflow on the supply side.

The structure of such a rotary adsorption element is disclosed in Patent Document 1. Further, the structure of a batch type adsorption element is disclosed in Patent Document 2.

  However, the conventional adsorptive element has the following problems.

  In the case of the rotary adsorption type element, the cylindrical block body has three configurations: a cylindrical block, a frame that covers the outside of the cylindrical block, and a core that is arranged at the center of the cylindrical block.

  The cylindrical block is used for moisture adsorption / desorption and heat exchange, the frame is used as a reinforcement when the cylindrical block is made of a brittle material, and the core rotates the cylindrical block body. It arrange | positions so that the rotating shaft used as the center may pass through a cylindrical block body.

  Two airflows having different properties are separated by a casing, and moisture exchange and heat exchange are continuously performed by passing the two airflows through the cylindrical block body while rotating the cylindrical block body with a motor or the like.

  The performance of the adsorptive element is improved by maintaining the separated state without mixing two airflows having different properties.

  However, when the casing is slid and rotated with respect to the cylindrical block, the frame and the core constituting the cylindrical block body, all the sliding surfaces of the cylindrical block, the frame and the core are rotated. If the surface is not smooth, there is a problem that a gap is formed between the casing and the casing.

  There are three possible causes for this gap: a gap between the casing and the frame, a gap between the casing and the cylindrical block, and a gap between the casing and the core.

  In the case of a dehumidifying element, a high-humidity airflow is passed through the cylindrical block on the processing side to obtain a low-humidity airflow, and at the same time, heating on the regeneration side is performed with a heater or the like to desorb the moisture on the processing side to obtain high-humidity air. However, if there is a gap in one of the three locations, a low-humidity airflow and a high-humidity airflow are mixed, leading to a decrease in moisture exchange efficiency. In the case of the heat exchange element, heat exchange is performed between the air flow taken in from the outside air and the air flow exhausted from the room air. However, as in the case of the dehumidifying element, the heat exchange efficiency is reduced by the gap.

  In addition, in the case of a batch-type adsorption element, it is possible to surely separate two airflows with different properties, but this requires a dumbbell that separates the two airflows and a device that controls the airflow, resulting in higher costs and switching. There was a problem that continuous processing could not be performed due to loss due to.

  The present invention solves such a conventional problem, and an object of the present invention is to provide an adsorption-type element having high performance because the gap between the cylindrical block body and the casing can be eliminated.

  In order to achieve the above object, the adsorption element of the present invention eliminates the gap between the cylindrical block body and the casing.

  By this means, it is possible to reliably separate two airflows having different properties flowing into the cylindrical block body, thereby obtaining an adsorption element having high performance.

  ADVANTAGE OF THE INVENTION According to this invention, the adsorption type element which eliminated the clearance gap between a cylindrical block body and a casing can be provided. For this reason, in the case of the dehumidifying element, the reverse flow of moisture from the regeneration side to the processing side is eliminated, and the dehumidifying performance is improved. Further, in the case of the heat exchange element, there is no leakage from the exhaust side to the supply side, and the ventilation efficiency is improved.

  The adsorption element according to claim 1 of the present invention is provided with a core at the center of the cylindrical block, and sandwiched between the upper and lower end surfaces of the cylindrical block body which is reinforced by covering with the frame, and the frame, the cylindrical block, and the core. In an adsorption type element that rotates by sliding a casing and three places, an elastic body seal is provided on the casing side, and a spring coil for sandwiching the cylindrical block body between the casings is provided, and a gap between the cylindrical block body and the casing is provided.
