Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of controlling a radiant heating/cooling panel that changes the amount of radiant heat dissipated depending on the room temperature.

Conventionally, radiant heating and cooling panels are often used in combination with forced convection heating and cooling systems, but the reason for this is that radiant heating and cooling panels usually have low capacity when used alone, and forced convection heating and cooling panels are Because upper and lower hot water temperature distribution tends to occur,
It is used as a supplement. In this case, forced convection type air conditioners often control the room temperature by turning the heat source on and off or by switching between high and low, and as shown in Figure 6 θ1°, there is a differential of plus or minus several degrees Celsius with respect to the set temperature θ0. Change. This has constant ability Q
When O's radiant heating/cooling panel is used in combination, the sensible temperature (virtual temperature felt by room temperature and radiant heat) at a certain point in front of the panel becomes '5' as shown at θ8° in the figure. In this case, if the comfortable range is expressed as Rn, it will be hot if Rh is out of this range.
In Rc, inconveniences occur whenever it gets cold. In order to improve this drawback, a method has been devised in which the amount of radiant heat radiated from the radiant panel is controlled as shown in FIG. 7 Q1 according to changes in the room temperature to keep the sensible temperature constant. This method changes the amount of radiant heat dissipated by radiation and positive channels with respect to the room temperature in the relationship shown in FIG. 8, and the sensible temperature becomes constant as shown at θ81 in FIG. 7. However, the radiant heat that occupants receive from the radiant panel varies greatly depending on the location in the room, and even if a certain sensible temperature is obtained in a certain limited location, the radiant heat may be close to the panel (θsa in the figure) or far away (θsa in the figure). middle θsb)
This leaves the problem that the user deviates from the comfortable range Rn and feels uncomfortable.

It is an object of the present invention to eliminate the above-mentioned conventional drawbacks and provide comfortable heating and cooling in a room where the room temperature fluctuates using a radiant heating and cooling channel.

In order to achieve this objective, the present invention provides a control device for controlling the amount of radiant heat dissipation according to the distance between the radiating surface and the occupant in a radiant heating/cooling system that detects the indoor temperature and changes the amount of heat dissipated. With this configuration, when the occupant is near the radiant panel, the average amount of radiant heat released from the radiant panel and the width of its change are made smaller, and conversely, when the occupant is far away, the width is made wider, so that it can be adjusted anywhere in the room. This design has been designed to provide a sense of comfort. An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

1 is a radiant heating/cooling panel main body of the present invention, which has a surface heating element 2 on the front and a control device 3 inside. Further, the control device 3 is provided with a sensible hot water temperature setting switch 4 and a distance setting switch 6 from the surface of the radiant panel. Fig. 2 is a block diagram of the control device 3, which includes a sensor 6 that detects the room temperature, a block 7 that calculates the required amount of radiant heat radiation based on the sensible temperature set value, the indoor air temperature, and the set distance from the surface of the radiant panel, and It is constituted by a block 8 which generates a control signal based on the control signal.

The operation during heating in the above configuration will be explained. The indoor air temperature in FIG. 3 changes as shown by θi in FIG. 4.

This room temperature is detected by the room temperature sensor 6, but if the set sensible temperature is set to θ8 and the set distance is set to B in Figure 3, these values are calculated in block 7, and the necessary radiation at position B is calculated. The amount of heat radiated is conveyed to 8 every moment and emitted from the radiation noonel.

That is, as shown in FIG. 4 QB, at time t1 when the room temperature is low
In this case, the amount of radiant heat dissipated from the radiant panel is increased, and the amount of radiant heat dissipated is decreased as the width of the room becomes higher, and control is performed such that it is minimized at time t2 when the room temperature is high. In addition, if the occupant is located further away from the radiant panel (Fig. 3), if the distance setting switch 6 is set accordingly, the amount of radiant heat will be changed to the average value and the change as shown in Fig. 4 QA. Both the widths of the temperature range are largely controlled, and a constant sensible temperature θB (FIG. 4) can be obtained at the position shown in FIG. 3.

On the other hand, at a position where the occupant is closer to the radiant panel (FIG. 3C), the amount of radiant heat is as shown in FIG. 4 Qc. Also, Fig. 6 shows 0 at each position A, B, and C in the above operation.
8 shows the relationship between the room temperature and the amount of radiant heat when a constant sensible temperature is given.

Therefore, according to the radiant heating and cooling panel of this embodiment, by setting the desired sensible temperature and position, the resident can
In fact, even in a room where the temperature changes, it is possible to always provide a constant perceived temperature regardless of the occupant's position, making it possible to provide extremely comfortable heating and cooling without making the occupants feel too hot or cold. Become.

Next, although not shown, other embodiments of the present invention will be briefly described.

In the first embodiment, the distance between the occupant and the radiant heating/cooling channel was manually set, but in this embodiment, a sensor is provided to automatically detect the occupant's position.

The amount of radiant heat is controlled according to that signal, the signal from the room temperature sensor, and the set sensible temperature.The same effect as the first embodiment can be obtained, and the resident can set the distance every time he or she moves. This has the effect of reducing the hassle.

As is clear from the above description, the radiant heating/cooling panel of the present invention controls the amount of radiant heat dissipated according to the indoor temperature and the positional relationship between the radiant surface and the occupant, so it can be used indoors where the temperature changes. It is possible to always obtain a constant sensible temperature no matter where you are, and realizes extremely comfortable heating and cooling effects.
