That is, in the upper surface of the flat plate 25 made of plastic such as PVC (polyvinyl chloride) or PET (ethylene terephthalate), the corner portion is a curved surface 26, and the upper end portion of each side wall surface 27 is formed. A small semicircular stop 28 is not protruded, and on the other hand, there is a certain interval between the protrusions 30 that are close to each other and the fixed and hot water supply pipe 12 is fixed, and is serrated and protrudes across the plurality of columns. The inside of the flat plate 25 is provided with a square-shaped projection 30 having a hollow portion 29; on the other hand, the flat plate 25 is formed between the projections 30 protruding in the zigzag shape, and the bottom surface is grounded to the floor panel 21 so as to be grounded. Have a cross section cup with depth When the grounding fixing plate 32 of the recessed portion 31 is grounded to the layer plate 21, the underfloor mounting type air conditioner indoor unit 22 can be formed between the grounding fixing plates 32 on the layer plate 21. The cooling member 33 that generates cold air or hot air forms the fixing member 34 of the hot and cold water supply pipe 12. That is, each of the projections 30 and the grounding fixing plate 32 having the recessed portion 31 having a cross-sectional cup shape are alternately arranged, and these are arranged across a plurality of rows.

When the outer peripheral surface of the flexible hot and cold water supply pipe 12 made of polyethylene is slidably attached to the side wall surface 27 of each of the projections 30 which are close to each other by the fixing member 34 having the above-described structure, the outer peripheral surface is pressed downward.

Further, the covering member 35 is covered with a floor panel 19 such as a floor panel or the like to form a floor panel device C.

Further, the fixing member 34 constituting the floor panel device of the present invention is not particularly limited, and may be, for example, a square fixing member 34 having a size of about 50 to 100 cm, preferably 90 cm, and depending on the size of the construction site. appropriate The plurality of fixing members 34 are fixedly connected to each other, thereby forming a size that can be adapted to any construction site. Further, when the fixing member 34 is formed to have a width of preferably 90 cm, the number of rows in which the plurality of projections 30 and the grounding fixing plate 32 formed in the fixing member 34 are alternately arranged is based on the width of the hot and cold water supply pipe 12. It is determined that, in the case where the width of the hot and cold water supply pipe 12 is 17 mm, the length and width are set to nine columns.

That is, as shown in FIG. 6, each of the protrusions 30 and the ground fixing plate 32 which are formed in the outermost row of the two adjacent sides of the square fixing members 34 having the plurality of projections 30 and the ground fixing plate 32 are formed. The connection portion 36 is provided, and each of the projections 30 and the grounding fixing plate 32 in the outermost row of the other two sides other than the coupling portion 36 is a connected portion 36a, and is formed so as to overlap either side of the connecting portion 36.

The outer diameter of the hollow portion 29 of each of the projections 30a of the outermost two rows adjacent to each other is formed to be slightly larger than the outer diameter of each of the projections 30b constituting the outermost rows of the two sides of the joined portion 36a. The protrusion 30a can be fixed by being covered by the protrusion 30b, and the inner diameter of each of the ground fixing plates 32a constituting the outermost two sides of the connected portion 36a is formed to constitute the connected portion. The inner diameter fixing plates 32b of the outermost rows of the remaining two sides of 36a have a slightly smaller inner diameter, and the grounding fixing plates 32a can be fitted and fixed from above the grounding fixing plates 32b to form the joint portions 36, respectively.

Further, the reason why the four corner portions 25a of the fixing member 34 are formed in a planar shape without protruding the projections 30 is that the corner portions 25a are connected to each other when the two fixing members 34 are fixed to each other. In the common overlapping portion of the portion 36a, for example, if any of the projection 30a and the projection 30b is provided in each corner portion 25a, or any of the ground fixing plate 32a and the ground fixing plate 32b is provided, at each corner portion 25a Since the cover 30b is not necessarily provided to fix the projection 30b of the projection 30a or the ground fixing plate 32b of the ground fixing plate 32a is fitted, the fixing member 34 cannot be coupled and fixed.

A method of connecting and fixing the fixing member 34 including the connecting portion 36 and the connected portion 36a, which is configured as described above, will be described with reference to FIG. 7. In FIG. 7, the fixing member of the component symbol 34a is superposed on the component symbols 34b, 34c. The fixing member of the fixing member, the fixing member of the component symbol 34b is a fixing member of the fixing member of the component symbol 34d, and the fixing member of the component symbol 34c is a fixing member of the fixing member of the component symbol 34d. Further, as shown in FIG. 8, for example, each of the projections 30a and the grounding fixing plate 32a which constitute the outermost row of the connecting portion 36 of the fixing member 34a on the overlapping side are fitted and inserted from above, and are pressed against the above. Each of the projections 30b on the outermost side of the joined portion 36a of the overlapping side fixing member 34b and the ground fixing plate 32b are integrally joined and fixed to each other by the two fixing members 34a and 34b. Further, as described above, each of the projections 30a on the side of the coupling portion 36 and the grounding fixing plate 32a can be fitted and inserted into the projections 30b and the grounding fixing plate 32b of the connected portion 36a from above, until the setting at the construction site is satisfied. The plurality of fixing members 34 are superposed and fixed to each other until the installation width is set.

In the floor radiant heating and cooling room apparatus A constituted by the above configuration, the mechanism for generating cold water or hot water by the heat exchanger 4 is firstly compressed and condensed by a heat pump outdoor unit 1 in the cold room, so that the discharged refrigerant is formed into a liquid state. After flowing into the electronic expansion valve 8 disposed between the refrigerant outflow pipe 3 and the heat exchanger 4, the heat exchanger 4 is evaporated to form a gas (gas), and is cooled by the latent heat of evaporation to circulate on the water side of the heat exchanger 4.
