Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To improve a heat exchanging efficiency between either return air or supply air and slabs in order to perform an effective utilization of the slabs as heat accumulating medium. SOLUTION: A finish floor is arranged on a slab 1 to keep a double space 4 acting as a passage for return air or supply air between the slab and the finish floor and then a heat exchanging operation is carried out with air while the slab is applied as a heat accumulating medium. Turbulence flow promoting members 5 for use in making an air flow within the double floor space into a turbulence flow state are fixed to supporting columns 3 for supporting the finish floor. A surface of the slab is formed with some corrugations 6 for improving a heat exchanging efficiency between the slab and the air.  As the turbulence promoting members 5, it is preferable to provide a member having a configuration in which an air flow direction is changed to flow in a downward direction to blow the air flow against the surface of the slab, or a configuration in which the direction of air is changed to flow toward a side to cause the air flows to be struck against to each other, or a configuration in which an air flowing direction is changed to a slant downward direction to cause the air flow to be blown against the surface of the slab and then the air flows are struck against to each other.

IPC: C07C67/08
Filed: 1987-08-21
Abstract: PURPOSE:To obtain the titled compound useful as a raw material for synthetic polymers, coatings, etc., in high yield, by reacting methacrylic acid with an alcohol in the vapor phase in the presence of tantalic acid. CONSTITUTION:Methacrylic acid is reacted with a 1-8C alcohol in the presence of tantalic acid catalyst at 120-300 deg.C under atmospheric pressure or several hundreds of mmHg-10kg/cm<2>G pressure in an inert gas atmosphere, such as nitrogen or helium, to afford the aimed substance. The tantalic acid is obtained by hydrolyzing a halide (e.g. TaCl5) of pentavalent tantalum to provide tantalum hydroxide which is a precursor, washing the resultant tantalum hydroxide with an acid and/or water and heat-treating the washed substance. The methacrylic acid and alcohol are used at 1:50-5 molar ratio.
