[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling / heating dehumidifying system for cooling / heating a room partitioned by floors, walls and ceilings.

2. Description of the Related Art Conventionally, as a cooling / heating system, for example, the Air Conditioning and Sanitary Engineering Society, edited by Air Conditioning Equipment Planning and Design (Ohm Du), pages 203 to 209 (19)
1995), which is installed on a wall, as represented by a home air conditioner,
It has a cooling and heating unit having a cooling and heating coil composed of a tube with a high heat transfer coefficient. By flowing a refrigerant or cold and hot water through the cooling and heating coil and forcibly applying air to the coil surface with a fan, the cool air or the hot air is cooled. The air is discharged into the room, and forced convection of the air is generated in the room to perform the cooling and heating dehumidification. Also, conventionally,
For example, there is a study on the air conditioning system combined with radiation panel 1st report-Proposal of the system and basic characteristics of the indoor environment, Summary of academic lectures of the Architectural Institute of Japan, August 1992 (Hokuriku). Installed on the floor, about 80 width
It has a cooling / heating unit in which plate-like tubes of about mm are arranged vertically at the same intervals of about 40 mm to about 50 mm, with cold or hot water flowing through the tubes. The water vapor is condensed and dehumidified, and cooling is performed by cooling airflow due to natural convection and radiation on the tube surface. In winter, heating is performed by warm airflow due to natural convection and radiation on the tube surface.

[0003]

By the way, in this conventional cooling and heating system, in the former, the cooling and heating unit is relatively small and easy to install, but the cooling and heating is performed by forced convection by a fan, so that the hot air is heated. In the case of (1), there is a drawback that the comfort is low because the apparatus is exposed to cold / hot air having a temperature higher by 10 ° C. to 20 ° C. than the set temperature and 10 ° C. to 15 ° C. lower than the set temperature. In addition, adverse effects due to fan noise also occur. In particular, when the air conditioner is used at nighttime with individual cooling and heating in a general house, a hospital, or the like, there is a disadvantage that the noise of the fan hinders a good night's sleep. on the other hand,
In the latter case, compared to the case of forced convection by the fan described above, there is no noise from the fan and the comfort is good due to the effects of radiation and natural convection, but the cooling and heating unit must be installed on the floor. There is a drawback that the degree of freedom of use of the space is limited. In addition, there is a problem that the weight of the cooling and heating unit is large, and the installation is accordingly complicated. Furthermore, since a large number of plate tubes are provided, the amount of heat radiation tends to be excessively large. Therefore, when the tube is provided close to the wall, there is a disadvantage that the wall surface is excessively cooled during cooling in summer or the like, so that dew condensation easily occurs. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and enables cooling and heating by radiation and natural convection. In particular, it is possible to suppress the occurrence of dew condensation on a wall surface or a ceiling surface during cooling. Thus, an object of the present invention is to provide a cooling and heating dehumidifying system in which the degree of freedom of use of an indoor space is not restricted while ensuring comfort.

[0005]

In order to achieve the above object, a cooling and heating system according to the present invention is provided in a cooling and heating dehumidifying system for cooling and heating a room partitioned by floors, walls, and ceilings. A pipe through which a medium made of cold water or hot water flows, a support that supports the pipe on at least one of the wall and the ceiling, and a medium supply unit that selectively supplies a medium made of cold water or hot water to the pipe. And the interior of the room is cooled and heated by natural convection by heat transfer from the pipe. As a result, since the weight of the pipe is light, installation work can be easily performed.In addition, in the mounted state, the pipe is located above the floor. Can be widely used,
Effective use of the floor is achieved. At the time of cooling in summer or the like, cooling and dehumidification are performed by natural convection having a low airflow velocity due to heat transfer from pipes when cooling water is supplied. As a result, compared to a conventional air conditioner that forcibly blows air, there is no discomfort due to wind and no noise is generated, so that comfort is improved. In particular, during cooling in the summer or the like, since the pipes are used, the amount of radiation and the amount of heat radiation are relatively small as compared with the conventional case. The situation where dew condensation occurs due to excessive cooling of the ceiling surface is suppressed, and cooling is performed to every corner of the room due to occurrence of natural convection.

If necessary, a gutter is provided below and along the pipe, and is provided with a gutter supported by the support and for receiving water that is condensed and falls on the pipe. Since water can be received from the pipe surface during cooling, water is prevented from splashing into the room. In this case, it is effective that the gutter is provided with a ridge that is bent inward along the center in the longitudinal direction. As the rigidity increases and becomes stronger, the rebound of the water drops hits the ridges and interferes, so that the water drops can be reliably received.

[0007] Further, the pipe comprises a core tube through which a medium passes, and fins formed on the surface of the core tube. Since fins were provided,
The surface area increases, and heat exchange with air is performed smoothly. In this case, the heat radiation rate per meter of the pipe is 2.0 to 2.0.
It is effective that the temperature is set to 2.5 w / m ° C. or more. This ensures that heat exchange with air is performed smoothly. Also,
If necessary, a plurality of the pipes are arranged vertically. Compared to a single case, the amount of heat exchange with the air can be increased, and the cooling and heating capacity and the natural convection speed can be increased. Further, as required, a curtain plate for covering the pipe is provided outside the pipe. The pipe can be concealed, so it looks better. Furthermore, a filter is provided above the pipe for absorbing dust falling on the pipe. This prevents contamination of the pipe. In this specification, the room is not limited to a closed space, but also includes a hallway, a staircase, and a part of which is open to the outside.

It is preferable to install the pipe 10 in the winter in the vicinity of the corner 3 where the ceiling 3 and the wall 2 or the wall 2 and the wall 2 intersect each other so as to prevent dew condensation. Is also good. In addition, pipe 10
Can be installed in any of the horizontal, vertical, and oblique directions, and may be determined according to the situation of the installation location. The length of the pipe 10 to be used is determined by the demand for cooling and heating, but it is preferable to install several pipes collectively and use the gutter 15 in common from the viewpoint of effective use of space. In the embodiment, as shown in FIGS. 1 and 5, a plurality of pipes 10 (two pipes in the embodiment) are vertically arranged, and the pipe 10 is located near the intersection of the ceiling 3 and the wall 2, And the wall 2 along the intersection line. In the embodiment, as shown in FIG. 2, in the four rooms 4, the ceiling 3 and the wall 2 of each room 4 are provided.
Along the intersection line with, a pipe is formed in a rectangular frame shape. The pipes in each room are parallel pipes.

The gutter 15 is, as shown in FIG.

Also, as shown in FIG.
A curtain plate 28 covering the pipe 10 is provided outside the pipe 0 and in front of the pipe 10. The curtain 28 is, for example,
It is formed of a suitable material such as wood, metal, plastic plate, etc., and is attached to the continuous plate 23 of the support 20 with bolts or the like. Further, a plate-like filter 29 that extends along the pipe 10 and adsorbs dust falling on the pipe 10 is provided above the support 20 attached to the wall 2. As the filter 29, for example, a nonwoven fabric or the like is used.
Since the pipe 10 itself has no electric wiring and is simple in structure, it can be washed with water. However, the provision of the filter 29 prevents dust from adhering and makes the washing almost unnecessary.

In the embodiment, the medium supply unit 30
As shown in FIG. 3, a supply pipe group 31 and a return pipe group 32 are provided in parallel with the pipes 10 in each room 4, and the medium generated by the heat pump 35 and the heat exchanger 36 is passed through the circulation pump 33. It is configured to circulate. Reference numeral 34 denotes a pump for circulating a medium to the heat pump 35 side. The heat pump 35 can selectively supply a medium composed of cold water or hot water by switching between cold and hot operations. The temperature of the cold and hot water passing through the pipe 10 depends on the required indoor environment, but the cold water is suitably 5 to 20 ° C, preferably 7 to 18 ° C, and the hot water is 25 to 60 ° C. Suitable, 30-45 ° C
Is preferred. The flow rate of cold and hot water also depends on the required indoor environment, but is 0.2 to 8 L per 1 m of pipe length.
/ Min is appropriate, and preferably 0.3 to 3 L / min.

Therefore, when the pipe 10 of the indoor air conditioning / dehumidifying system according to this embodiment is installed in the room 4, the support 20 is fixed to a required portion above the wall 2, and the support 20 is held. The pipe 10 is held and held in the holding recess 21 of the plate 22, and the gutter 15 is attached to the suspension member 25. Thereafter, the curtain plate 28 is attached to the support 20 and the filter 29 is provided. In this case, since the weight of the pipe 10 is light, the mounting operation is easily performed. In addition, in the mounted state, the pipe 10 is supported by the wall 2, so that the floor 1 can be widened as compared with a conventional floor-mounted cooling and heating unit, so that the degree of freedom of using the indoor space is increased. Increase. Further, since the curtain plate 28 that covers the pipe 10 is provided outside the pipe 10, the pipe 10 can be covered and concealed, and the appearance is improved. Further, since the filter 29 is provided on the upper side of the pipe 10, dust falling on the pipe 10 is adsorbed by the filter 29, so that the pipe 10 is prevented from being contaminated and the heat exchanger function of the pipe 10 is prevented from being impaired.

Further, when cooling and heating is performed by the indoor cooling and heating dehumidifying system according to this embodiment, the following is performed. First, in the summer or the humid period, the cooling water medium is supplied by switching the heat pump 35. Thereby, the cold water reaches the pipe 10 through the supply pipe group 31 and circulates through the return pipe group 32. During the circulation of the cold water, since the pipe 10 is cooled, the air around the pipe 10 is cooled, and natural convection with a low airflow velocity occurs above and below the pipe 10, whereby the room 4 is gradually cooled. Go. In addition, since the temperature of the pipe 10 is low, dew condensation occurs on the surface of the pipe 10, especially on the surface of the fins 12, whereby the interior 4 is dehumidified. The condensed water falls into the gutter 15 as water droplets and is discharged from the drain to the outside. Further, since the pipe 10 is used, the amount of radiation and the amount of heat radiation are relatively small. Therefore, even when the pipe 10 is provided close to a wall or a ceiling, a situation in which the wall surface or the ceiling surface is excessively cooled and dew is suppressed is suppressed. At the same time, natural convection is generated to cool the interior of the room.

In this case, cooling and dehumidification are performed by natural convection having a low airflow speed, so that there is no discomfort due to wind and no noise as compared with the conventional air conditioner that blows out forced air. A comfortable indoor environment is obtained. Also, a gutter 15 is provided below the pipe 10 for receiving water that is condensed on the pipe 10 and falls.
Water can be received from the surface of the pipe 10 during cooling, and the situation where water scatters in the room 4 is prevented. Further, since the gutter 15 is provided with a ridge 16 which is bent inward along the center in the longitudinal direction, the rebound of the water droplet collides with the ridge 16 and is interfered with, so that the water droplet can be reliably received.
Furthermore, although two pipes 10 are provided, they are arranged vertically one above the other, so that even one gutter 15 can receive drops of water drops from a plurality of pipes 10. Further, the pipe 10 has a fin 1 on the surface of the core tube 11.
2, the surface area increases, and heat exchange with air is performed smoothly. In particular, 1m of pipe 10
Since the heat radiation rate per unit is set to 2.5 w / m ° C. or more, heat exchange with air is performed smoothly and cooling efficiency is improved. Furthermore, since a plurality of pipes 10 are arranged vertically, the amount of heat exchange with the air is increased and the cooling capacity is increased as compared with a single pipe.

On the other hand, in winter, the operation of the heat pump 35 is switched to the heating side, so that the hot water reaches the pipe 10 through the supply pipe group 31 and circulates through the return pipe group 32.
During the circulation of the hot water, since the pipe 10 is heated, the air around the pipe 10 is warmed, and the ceiling 3 and the wall 2 around the pipe 10 are also heated, so that radiation and airflow therefrom are slow. The room 4 is gradually heated by natural convection. In this case, heating is performed by weak radiation from the ceiling and walls and natural convection with slow airflow,
Compared with the conventional air conditioner that blows out the wind forcibly, there is no discomfort due to the wind, so that a comfortable indoor environment can be obtained. Further, the pipe 10 is a core tube 1
Since the fins 12 are provided on the surface of the first member, the surface area increases, and heat exchange with air is performed smoothly. In particular, the heat radiation rate per meter of the pipe 10 is 2.5 w / m ° C.
With the above settings, the heat exchange with the air is performed smoothly and the heating efficiency is improved. Furthermore,
Since a plurality of pipes 10 are arranged vertically above and below, the amount of heat exchange with air is increased and the heating capacity is increased as compared with a single pipe.

In the above embodiment, the pipe 1
Although two 0s are provided side by side, the present invention is not necessarily limited to this. For example, as shown in FIG. 6, one may be used and may be changed as appropriate.
It should be created for the book. Also, in FIG.
The filter 8 is formed of the same material as the filter 29, and the filter 29 and the curtain plate 28 are integrated to have a filter function as a whole. Also, in the pipes in the room 4, it is not necessary to arrange two pipes 10 side by side in all the rooms. In consideration of the size of the room, etc., two pipes 10 are used in combination with one pipe. Of course you can do it. Also, three or more units may be used. Further, in the above-described embodiment, the support 20 is configured to be fixed to the wall 2, but is not necessarily limited to this, and may be fixed to the ceiling 3. It may be configured to be fixed to both of the ceilings 3 and may be changed as appropriate.
Further, the pipe 10 may be installed, for example, on the wall 2 in a direction perpendicular or oblique to the ceiling 3 on the wall 2 or in a bent shape according to the design convenience of the installation place or the demands on the design. Good.
