However, these conventional heating devices and cooling devices directly hit the body when hot or cold air circulates in the room, and extremely heat or cool the surface of the body. And sometimes caused discomfort. There is also a problem that the temperature of the indoor air becomes uneven because warm air rises to the upper part of the room and cooler air descends, and the feet become cold even though the head is hot. Was.

[0005] A cooling device using electricity such as a room cooler consumes a large amount of electricity. Also, when Freon as a refrigerant is released into the atmosphere, there is a risk that the ozone layer of the earth will be destroyed and the environment will be adversely affected. Therefore, an object of the present invention is to provide a health-friendly cooling and heating device that can provide a uniform cooling and heating effect indoors.

[0006]

[Means for Solving the Problems] (Means) In order to solve the above problems, a first cooling and heating device according to the present invention comprises, as illustrated in FIG. Has a pipe passing therethrough, a gutter 9 provided below along the pipe, and connecting means for connecting the pipe and the gutter, and the pipe, the gutter and the connecting means are integrally formed by extrusion. It is characterized by being formed.

A third cooling and heating device is characterized in that the surface of the gutter is covered with a far-infrared radiation film. The fourth cooling and heating device is characterized by having fins provided radially along the axial direction of the gutter. A fifth cooling and heating device is characterized in that it has fins radially provided along the axial direction of the pipe.

[0008] A sixth cooling and heating device is characterized in that the gutter is inclined so that dew condensation flows in one direction. A seventh cooling / heating device is characterized by including a U-shaped pipe and a flange for connecting the pipes to each other. The eighth cooling and heating apparatus is characterized in that the pipe, the gutter, and the connecting means are accommodated in a casing having an open lower surface so that radiant heat flows in and out.

[0009] A ninth cooling and heating device is characterized by comprising a blower fan for sending air to pass through the surface of the pipe. The tenth cooling / heating device is characterized in that a fitting portion formed in a U-shape is provided at both ends in the width direction of the gutter. The eleventh cooling and heating device is characterized in that it has a plate member that connects the adjacent gutter, the connecting member, and the pipe by being fitted into each of the U-shaped fitting portions of the adjacent gutter. . (Operation) Next, the operation of the air conditioner of the present invention will be described.

[0010] The ninth cooling / heating device includes a blower fan for sending air toward the pipe. The tenth air conditioner is
The pipe, the heat radiation absorbing member, and the U-shaped tube are housed in a casing. In an eleventh cooling / heating device, the casing includes a heat reflecting plate of inner aluminum. (Operation) Next, the operation of the air conditioner of the present invention will be described.

[0011] When heating with the cooling and heating apparatus of the present invention in winter, hot water is flown as a heat medium through the pipe. The heat of the hot water raises the temperature of the pipe, and the heat is transmitted to the heat radiation absorbing member. Since a film of a material that radiates far infrared rays is formed on the surface of the heat radiation absorbing member, the transmitted heat is radiated as far infrared rays. Far-infrared rays are easily absorbed by the human body, and when absorbed into the human body, penetrate into the inside to promote the self-heating action of molecules, thereby warming the human body from the inside.

When cooling is performed in summer, cold water is supplied as a heat medium to the pipes. By the action of the cooling water, the temperature of the heat radiation absorbing member decreases. The cooled heat radiation absorbing member absorbs heat rays from a human body surface at a higher temperature based on the exergy theory. As a result, the surface temperature of the human body decreases, and a cooling effect is obtained. Further, in the cooling by the room cooler, the relative humidity is increased to reduce the temperature of the indoor air, and the sweating from the human body is reduced. The sweating from the human body surface is promoted without lowering the temperature of the body so that healthy cooling is possible.

Heating and cooling by the cooling and heating device according to the present invention utilize heat radiation, so that unlike a stove or a room cooler, hot air or cold air does not directly hit the human body, which is good for health and uniform indoors. A great cooling and heating effect can be obtained. Further, since a coating film that radiates far-infrared rays is used, a sufficient cooling effect can be obtained even if the temperature of the refrigerant is not too low, so that electricity can be saved as compared with a conventional room cooler or the like. Furthermore, since no harmful gas such as chlorofluorocarbon is used as the refrigerant, there is little risk of harm to the environment.

Further, by providing the fins in the pipe or the heat radiation absorbing member through which the heat medium passes, the area for radiating or absorbing heat is increased, and the cooling and heating efficiency can be improved. Also, by forming the heat radiation absorbing member in the form of a gutter, the dew formed on the pipe surface due to the cold water flowing through the pipe during cooling can be collected and discharged to the outside, so that the building is wetted by the dew and damaged. Can be prevented.

Further, since the pipe and the heat radiation absorbing member can be integrally formed by extrusion molding, the manufacture is extremely easy. In addition, by connecting a plurality of pipes with a U-shaped pipe, a cooling and heating device having cooling and heating capacity as required can be easily configured. In addition, by sending air to the pipe with a fan, evaporation of dew condensation generated on the pipe surface during cooling can be promoted to enhance the cooling effect.

Further, by housing the pipe and the heat radiation absorbing member in a casing and providing a heat reflecting plate made of an aluminum sheet or the like inside the casing, heat radiated from the pipe or the heat radiation absorbing member is reflected to the indoor side. As a result, the heating effect can be enhanced.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a cooling and heating device according to an embodiment of the present invention. The air conditioner 1 is attached to a ceiling 2 of a room. In the cooling / heating device 1, a heat radiation absorbing mechanism 4 and a fan 5 are surrounded by a casing 3. In this figure, the casing 3, the heat radiation absorbing mechanism 4, and a part of the fan 5 are cut away for easy understanding of the structure. The casing 3 has an open lower surface, and is attached so that its opening matches the opening (not shown) of the ceiling 2. A reflective plate 6 made of a thin aluminum plate is attached to the inside of the casing 3.

The heat radiation absorbing mechanism 4 includes five heat medium pipes 7 arranged horizontally with the surface of the ceiling 2, each heat medium pipe 7 connected by a U-shaped pipe 8, and a heat medium pipe 7 and a U-shaped pipe. A gutter section 9 is arranged below 8. Water is flowed through the heat medium pipe 7 as a heat medium. One end of a drainage pipe 10 is connected to the gutter portion 9, and the other end of the drainage pipe 10 extends from the casing 3. The fan 5 is arranged in the casing 3 alongside the heat radiation absorbing mechanism 4. The fan 5 is rotated by an electric motor (not shown), sends wind in the direction of the heat medium pipe 7, and circulates air in the sheathing 3.

FIG. 2 is a perspective view, partially cut away, of the structure of the heat radiation absorbing mechanism 4 of FIG. 1 for easy understanding. Although not shown in FIG. 1, the heat medium pipe 7 has a plurality of fins 11 extending in the length direction around the heat medium pipe 7. At both ends of the heat medium pipe 7, there are flanges 12, which are connected to the flange of the U-shaped pipe 8 by bolts 13. Two fins 11 a protruding downward among the fins 11 of the heat medium pipe 7 are connected to the gutter 9. Gutter 9
Is formed in a boat shape with a lower center and a higher edge, and has fins 14 extending in the longitudinal direction on the lower surface. FIG. 3 shows the fins 11 and 14 formed on the heat medium pipe 7 and the gutter portion 9. On the surfaces of the heat medium pipe 7 and the gutter portion 9 and the surfaces of the fins 11 and 14, a coating film 15 made of a material such as ceramic that radiates far infrared rays is formed. Heat medium pipe 7 and U
The U-shaped pipe 8 and the gutter 9 are integrally formed by extrusion with a material having high thermal conductivity such as aluminum.

When heating is performed by the cooling and heating apparatus of the present embodiment, hot water of about 40 to 70 ° C. is supplied to the heat medium pipe 7. As a result, the heat medium pipe 7 and the U-shaped pipe 8 are heated, and the heat is transmitted to the fins 11. Since the surface of the heat medium pipe 7 has the coating film 15 of the far-infrared radiation material, heat is radiated from the fins 11 as far-infrared radiation. Since the thin aluminum plate 6 is provided inside the casing 3, far infrared rays emitted upward from the heat medium pipe 7 are also reflected downward and absorbed by the gutter 9. On the other hand, a part of the heat is transmitted directly to the gutter 9 via the fins 11 a of the heat medium pipe 7. In this way, heat is transmitted to the gutter portion 9 and the fins 14 on its lower surface. This heat is radiated as far infrared rays by the coating film 15 of the far infrared radiating material.

As shown in FIG. 1, since the lower surface of the casing 3 is open toward the room, far infrared rays radiated from the gutter 9 are radiated into the room. The far-infrared rays radiated into the room penetrate into the human body when they hit the human body, and promote the self-heating effect to warm the human body from the inside. Further, when cooling is performed in the summer by the cooling and heating device of the present invention, cold water flows through the heat medium pipe 7. This cold water may be cooled at 15 to 18 ° C. by well water or a heat pump. By this cold water, the heat medium pipe 7 and the fins 11 are cooled, and the connection fins 11
The gutter portion 9 and the fins 14 are cooled through a, and the temperature of the lower surface of the gutter portion 9 becomes about 20 ° C. At this time, since the human body surface temperature of the person in the room is 35 ° C., the heat rays on the human body surface are absorbed by the lower surface of the gutter 9 based on the exergy theory, and the human body is cooled. This is the same effect as feeling cool in a tunnel. The heat absorbed by the gutter 9 is applied to the connecting fins 1.
The heat is transmitted to the heat medium pipe 7 via 1a, and is absorbed by cold water.

When cold water passes through the heat medium pipe 7 in summer, the humidity inside the room adheres to the surface of the heat medium pipe 7 due to a difference in relative humidity depending on the temperature, and dew condensation occurs. If the dew increases, it becomes water droplets, travels along the connecting fins 11a, and falls inside the gutter portion 9. The water that has fallen inside the gutter 9 flows through the sloped gutter 9 and is discharged outside from the drain pipe 10. Further, the water droplets on the surface of the heat medium pipe 7 are promoted to evaporate by the wind sent from the fan 5, and the heat of vaporization cools the heat medium pipe 7, thereby increasing the cooling efficiency.

FIG. 4 is a sectional view of a heat radiation absorbing mechanism according to another embodiment of the air conditioner of the present invention. The heat radiation absorbing mechanism of the present embodiment is different from the heat radiation absorbing mechanism of FIG. 2 in that a connecting portion 16 is formed in the gutter 9 '.
By connecting the connecting portions 16 with the connecting members 17, the plurality of gutter portions 9 'can be easily connected. When the heat radiation absorbing mechanism 4 'having such a connecting portion 16 is used,
A cooling and heating device having a necessary heating capacity or cooling capacity can be easily configured.

In the above embodiment, the heat radiation absorbing portion is formed in a gutter shape, but any shape may be used as long as heat radiation and heat absorption can be efficiently performed. Further, by providing cuts or protrusions in the fins of the heat medium pipe, water droplets attached to the pipe can be easily dropped from the pipe. Further, in this embodiment, the cooling and heating device of the present invention is mounted on the ceiling, but it can be mounted on a convenient place such as a wall surface or a floor surface.

[0025]

As described above, in the cooling / heating device of the present invention, the heat medium pipe is thermally connected to the heat radiation absorbing member having the coating of the far-infrared radiating material. The warming water is used to provide a heating effect, and the cooling water is used in the summer to provide a cooling effect. During heating, far-infrared rays are emitted into the room from the coating of the far-infrared radiation material on the surface of the heat radiation absorbing member. Far infrared rays are easily absorbed by the human body and penetrate into the human body, so that the body can be warmed from the core. In addition, when used for cooling, heat is absorbed by the heat radiation absorbing member from the surface of the human body, and a cooling effect is obtained. In order to efficiently absorb heat rays from the human body, the coating film of the far-infrared radiating material can provide a sufficient cooling effect even if the temperature of the refrigerant is not too low, and can save energy required for cooling. In addition, since chlorofluorocarbon is not used as a refrigerant, environmental destruction due to chlorofluorocarbon can be avoided.

In addition, unlike the air conditioner using the fan heater or the room cooler, the air conditioner according to the present invention does not hit the human body with hot air or cold air, and does not soak up dust in the room. it can. Further, since the heat radiation absorbing mechanism of the present invention can be connected to an arbitrary number by the connecting tool, the room can be cooled or heated as needed.
