  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 and 2 show perspective views of an air conditioning system according to a first embodiment of the present invention. FIG. 3 shows a schematic diagram of the path of the airflow of the indoor air conditioning means and the radiating means.

  1 and 2, the indoor air conditioning means 11 is for making the indoor thermal state, air quality and the like a comfortable environment, and is an air conditioner such as a duct air conditioner, for example. In addition, a wall-mounted air conditioner is not limited at all as long as it is an air conditioner that makes the indoor thermal state and air quality comfortable.

  The indoor set temperature correction means 18 is a part of the control microcomputer unit of the indoor air conditioning means 11 and corrects the set temperature of the indoor air conditioning means 11 when the radiation surface reaches a predetermined temperature. It should be noted that, for example, the indoor air conditioning unit 11 that is an indoor unit of the indoor air conditioning unit 11 or the air conditioning system outdoor unit 14 is incorporated in any way as long as it corrects the set temperature of the indoor air conditioning unit 11.

The radiating means 12 warms or cools at least one of the indoor floor walls and ceiling surfaces. For example, the radiating means 12 blows warm air like a duct air conditioner to warm or cool the ceiling surfaces. is there. In addition, as shown in FIG. 5, the heat exchange pipe 51 is installed on the ceiling surface, and the cooled or heated fluid is allowed to flow through the heat exchange pipe 51 to cool or heat the ceiling so that the indoor space A is cooled or heated by ceiling radiation. There is no limitation as long as it is a radiable means.

  The controller 13 can set at least the indoor temperature, and can control the indoor air-conditioning means 11 and the radiating means 12 by, for example, an infrared signal from the controller.

  The air conditioning system outdoor unit 14 is an outdoor unit of the indoor air conditioning unit 11 and the radiating unit 12, and the number of units is not limited at all, such as having dedicated outdoor units for the indoor air conditioning unit 11 and the radiating unit 12.

  The indoor air conditioning means 11 and the radiating means 12 are installed on the ceiling 16, and the radiating surface 121 of the radiating means 12 is a part of the ceiling 17. The controller 13 is in the room 15 so as to be easy for the user to use.

  The user uses the controller 13 to set a favorite room temperature so that the room 15 becomes comfortable. For example, if the initial indoor temperature is 32 ° C. and the user's preferred indoor temperature is 27 ° C. in the summer, the indoor air-conditioning means 11 is provided with the air-conditioning as shown in the air flow path 31 in the indoor air-conditioning means of FIGS. The air cooled by the indoor unit 111 passes through the indoor air conditioning duct 112 and is blown out as cold air from the indoor blowing section 113 to the indoor 15 and is further sucked in by the indoor suction section 114 so that the room becomes 27 ° C. To do.

  Further, in the radiating means 12, as shown in the air flow path 32 in the radiating means of FIGS. 2 and 3, the air cooled in the radiating indoor unit 123 is radiated by the radiating duct 124, the ceiling circulation channel outlet 125, the ceiling circulation flow. The radiation surface 121 is cooled through the path 122, and further sucked in by the ceiling circulation flow path suction portion 126. For example, the radiation surface is operated so as to reach 20 ° C. that feels cold radiation.

  Here, indoor comfort will be described. Indoor comfort depends on room temperature, humidity, airflow, and radiation as environmental factors, as shown in, for example, PMV and SET *. For example, in the summer season, even if the humidity and air flow are the same, the latter feels colder in an environment of room temperature 27 ° C. and radiation 27 ° C. and room temperature 27 ° C. and radiation 20 ° C. It is necessary to set the temperature to 20 ° C.

  That is, since the user feels cold at the room temperature desired by the user, the room temperature needs to be 28 ° C. corrected by + 1 ° C.

  Therefore, the indoor set temperature correction means 18 sets the set temperature of the indoor air conditioning means 11 to 28 ° C. corrected by + 1 ° C. when the radiation surface reaches a temperature of 20 ° C.

  When time elapses from 32 ° C. in the room and the room reaches 28 ° C., the indoor air-conditioning unit 11 stops the operation, or controls the air volume to be a slight breeze so as to reduce the feeling of air flow or to avoid the wind direction from the user. .

  In addition, although it explained about summer, it is the same about winter.

For example, when the initial indoor temperature is 10 ° C. and the user's preferred indoor temperature is 22 ° C. in the winter season, the indoor air-conditioning means 11 is adapted to the air-conditioning as shown by the air flow path 31 in the indoor air-conditioning means of FIGS. The air heated by the indoor unit 111 passes through the indoor air conditioning duct 112 and is blown out as warm air from the indoor blowing unit 113 into the indoor 15 and is further sucked in by the indoor sucking unit 114 so that the temperature of the room becomes 22 ° C. drive.

  Further, in the radiating means 12, as shown in the air flow path 32 in the radiating means of FIGS. 2 and 3, the air warmed by the radiating indoor unit 123 is converted into the radiating duct 124, the ceiling circulation channel outlet 125, the ceiling circulation flow. Passing through the path 122, the radiation surface 121 is warmed and further sucked in again by the ceiling circulation passage suction portion 126, and for example, the radiation surface is operated so as to reach 30 ° C. that feels warm radiation.

  When time elapses from 10 ° C. in the room and the room reaches 22 ° C., the indoor air-conditioning means 11 stops the operation, or controls the air volume to be light or to avoid the wind direction from the user so as to reduce the air flow feeling. .

  The same applies to the comfort, and it is necessary to set the room temperature to 20 ° C. corrected by −2 ° C. because the user feels hot at the room temperature desired by the user.

  Therefore, in the indoor set temperature correction means 18, when the radiation surface reaches a temperature of 30 ° C, the set temperature of the indoor air conditioning means 11 is set to 20 ° C corrected by -2 ° C. The correction amount is not limited above.

  By driving as described above, the room can be made comfortable in a short time and a comfortable radiant feeling can be obtained. Moreover, it can correct | amend to more comfortable indoor temperature from the radiation state of a room | chamber interior. That is, it is possible to obtain a comfortable radiation environment with a feeling of airflow in a short time and a more comfortable radiation environment.

  Moreover, while making the room into a comfortable environment in a short time, a more unpleasant airflow can be suppressed. That is, it is possible to obtain a more comfortable radiation environment with less airflow.

  Next, FIG. 4 shows a schematic view of the flow of moisture in the radiating means in the first embodiment of the present invention.

  The radiating means 12 blows hot / cold air like a duct air conditioner to warm or cool the ceiling surface. Further, a moisture permeable material is used for the radiation surface 121.

  When the radiating means 12 performs the cooling operation, the air in the air flow path 32 in the radiating means is cooled and condensed by the heat exchanger inside the radiating indoor unit 123, and is discharged to the outside as drain water. As a result, the water vapor pressure in the ceiling circulation channel 122 becomes lower than the water vapor pressure in the room 15, and the moisture-containing air in the room 15 passes through the radiation surface 121 of the moisture-permeable material and moves to the ceiling circulation channel 122. Furthermore, the moisture 40 that has moved to the ceiling circulation channel 122 is similarly cooled and condensed by the heat exchanger inside the radiating indoor unit 123, and is discharged to the outside as drain water. These steps are repeated, and the moisture in the air in the room 15 is discharged to the outside of the room, whereby the humidity in the room can be lowered during cooling only by radiation operation.

That is, a refreshing and more comfortable radiation environment with low humidity can be obtained during cooling. Next, indoor comfort will be further described. For example, in summer, even if the airflow and radiation are the same, for example, the environment of room temperature 28 ° C, humidity 60%, radiation 20 ° C, airflow 0.3 m / s and room temperature 28 ° C, humidity 40%, radiation 20 ° C, airflow 0.3 m / s In s, since the latter feels colder, in order to achieve the same comfort, for example, room temperature 28.5 ° C., humidity 40%, radiation 20 ° C., and air flow 0.3 m / s are required.

  That is, since the user feels cold at the room temperature desired by the user, the room temperature needs to be further corrected by + 0.5 ° C. to 28.5 ° C.

  In addition, when the outside air temperature is high, the temperature other than the radiation surface controlled by the radiation means 12 becomes high, and accordingly, the room temperature needs to be slightly lowered. On the other hand, when the outside air temperature is low, the temperature other than the radiation surface controlled by the radiation means 12 becomes low, and it is necessary to slightly increase the room temperature accordingly.

  Therefore, in the indoor set temperature comfort correction means 19, at least one of the humidity and the outside air temperature detected from the humidity detecting means 20 for detecting the room humidity such as a humidity sensor and the outside air temperature detecting means 21 such as an outside air temperature sensor. The indoor set temperature is corrected from the user's preferred set temperature. Thereby, it is possible to make the room comfortable in a short time and to obtain a comfortable radiant feeling. Moreover, it can correct | amend to more comfortable room temperature from the radiation state of room | chamber interior, humidity, and external temperature. That is, it is possible to obtain a radiation comfortable environment with less airflow feeling in a short time and a more comfortable radiation environment.

  As described above, since the air conditioning system according to the present invention can create a comfortable indoor environment for radiation, it can be applied not only to ordinary houses but also to non-houses. Moreover, it can be applied not only to cooling but also to heating. Further, the radiation surface can be applied not only to the ceiling but also to wall surface radiation such as wall surfaces and floor surfaces, floor surface radiation, and the like.
