By using a method called radiant heating and cooling, a control signal is sent from the control device 6 to the radiant heating and cooling panel 9 based on the input value from the radiant temperature detection means 10, and optimal control is performed. As a result, the temperature near the desk 1 becomes optimal, making it possible to provide a more comfortable work space for the desk user.

The heating and cooling by the radiant heating and cooling panel 9 is effective in creating a so-called cold head and feet condition, especially during heating, but when the surface temperature of the radiant heating and cooling panel 9 is 6.
If the temperature exceeds 0°C, there is a risk of so-called low-temperature burns if a part of the body comes into contact with the radiant cooling/heating panel 9, so the surface temperature of the radiant cooling/heating panel 9 is controlled to be 60°C or lower. This is preferable from a safety standpoint.

Although a thermocouple is used here as the radiant temperature detection means 10, other types of so-called temperature sensors such as a thermistor, pyroelectric infrared sensors, or thermopile infrared sensors may also be used. Although it is installed on the bottom surface of the top plate 1, it goes without saying that the installation location is not limited to this.

In this embodiment, only the value detected by the radiant temperature detection means 10 is used to control the operation of the radiant heating and cooling panel 9, but the value is not limited to this and other information may be used. Furthermore, an adjustment mechanism may be provided that allows each desk user to adjust the temperature, etc. of the radiant heating and cooling panel 9. In this case, more detailed equipment control may be performed by the desk user's own self-reported information input. As well as becoming possible,
It gives desk users a sense of satisfaction that they are independently adjusting the radiant heating and cooling function, and as a result, it is possible to provide a work environment that is not only thermally sensual but also mentally fulfilling. preferable. By performing air conditioning individually for each desk user in this way, an energy saving effect can be obtained in that the load on the air conditioner for the entire room can be reduced.

Next, a fifth embodiment of the present invention will be described with reference to FIG. Note that functional parts that are the same as those in the fourth embodiment are given the same numbers and detailed explanations will be omitted. As shown in the figure, it has a lower body temperature detection means 11 that detects the body temperature of the lower extremities of the desk user, and a control signal reflecting the body temperature of the lower extremities of the desk user is sent to the radiant heating and cooling panel 9. As a result, the temperature near the desk 1 becomes optimal, making it possible to provide a comfortable work space for the desk user, and especially when heating the room, the lower body of the body tends to get cold. This makes it possible to create a very comfortable space for people. By performing air conditioning individually for each desk user in this way, an energy saving effect can be obtained in that the load on the air conditioner for the entire room can be reduced. Further, if the lower body temperature detection means 11 does not detect the body temperature of the desk user's lower limbs, the lower body temperature detection means 11 can also be used as a means for detecting the presence of the desk user, such as indicating that the desk user is not present. Therefore, it is possible to obtain favorable effects from the viewpoint of energy saving, such as stopping the operation of the radiant heating/cooling panel 9 when there is no desk user.

Cooling and heating by the radiant heating and cooling panel 9 is effective in creating a so-called cold head and feet condition, especially during heating, but if the surface temperature of the radiant heating and cooling panel 9 exceeds 60°C, the radiant heating and cooling panel 9 Because there is a risk of so-called low-temperature burns if a part of the body comes into contact with the panel 9, the surface temperature of the radiant heating and cooling panel 9 is set at 60
It is preferable for safety to control the temperature to below ℃.

Although a pyroelectric infrared sensor is used here as the lower body temperature detection means 11, other types of sensors such as a thermopile infrared sensor may also be used.
Although it is installed on the lower surface of the top plate 2 in this embodiment, it goes without saying that the installation location is not limited to this.

In this embodiment, only the value detected by the lower body temperature detection means 11 is used to control the operation of the radiant heating/cooling panel 9, but the value is not limited to this and other information may be used. Furthermore, an adjustment mechanism may be provided that allows each desk user to adjust the temperature, etc. of the radiant heating and cooling panel 9. In this case, more detailed equipment control may be performed by the desk user's own self-reported information input. As well as becoming possible,
It gives desk users a sense of satisfaction that they are independently adjusting the radiant heating and cooling function, and as a result, it is possible to provide a work environment that is not only thermally sensual but also mentally fulfilling. preferable.
