Description

[Detailed Description of the Invention] The present invention relates to a heating device that combines a floor heating machine that heats the floor surface and a warm air heater that heats a living space.

□It has long been known that the floor heating method is an ideal heating method.

＼ □ ・ ゛This provides an ideal thermal environment that keeps the head cold and feet warm, and since it is a heating method using a narrow width, there is no need to raise the room temperature to an extreme, and it is advantageous in terms of energy conservation b) 4.

On the other hand, since the human body comes into direct contact with the heated floor surface, it is necessary to keep the surface temperature below 30C.

□ ・′ □′ ・ ,...For this reason, ゛・Sufficient heating capacity is obtained.Since the east exit, which has a large heat exchange capacity, is heated, the rise time until reaching the specified comfortable heating range is slow. It has drawbacks such as poor controllability.

On the other hand, the hot air heating method, which heats the indoor air and causes convection,
Because it heats air with a small heat capacity, it rises quickly,
Since there is no heat source temperature limit like with floor heating, there is sufficient heating capacity and controllability is good.

However, since warm air is blown out, temperature differences tend to occur between the upper and lower parts of the room, and the circulating wind may cause discomfort due to the drag effect.

Here, the thermal sensation of the human body is determined by the balance between the amount of heat produced by the human body and the amount of heat released from the human body to the outside of the body (heat radiation amount).
It is generally said that it provides a comfortable level of comfort.

Heat release to the outside of the body is caused by the three elements b (convection, radiation, and evaporation). What?
Six gorge past trees.

Of the three factors mentioned above, it can be determined by the air released by convection, the air surrounding the human body, and the degree of radiation in the grave.

That is, the amount of heat dissipated by the axial flow in □ can be known by detecting the room temperature.

On the other hand, the amount of heat dissipated by radiation is determined by the temperature difference between the human body and the objects surrounding it, and when compared with the human body, the temperature b

By detecting the wall temperature and controlling the indoor temperature and floor temperature according to the wall temperature, the floor temperature is controlled by the indoor temperature and the floor temperature is controlled by the indoor temperature. The present invention provides a heating device that can provide a more comfortable indoor thermal environment.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3.

In FIG. 1, reference numeral 1 denotes a floor heating machine that heats a floor surface B of a room A, and has a built-in heating pipe (not shown) through which hot water, which will be described later, is circulated and supplied.

Reference numeral 2 denotes a hot air heater that heats the indoor space, and it has a configuration that includes a heat exchanger (not shown) to which hot water is circulated and supplied, which will be described later, and a blower 3 that supplies air that is exchanged with the heat of the heat exchanger (not shown). be.

8 is a hot water supply device that circulates hot water to the heating pipe of the floor heater 1 and the heat exchanger of the hot air heater 2; 11 is a hot water circulation pipe that supplies warm air from the hot water supply device 8 through a pump 9; A portion of the water reaches the heat exchanger of the heater 2, from which it returns to the hot water supply device 8 via the solenoid valve 10, and a portion of the water goes to the floor warmer 1.
The heating pipe is connected to the heating pipe, and is configured to merge with a pipe section returning from the hot air heater 2 to the hot water supply device 8.

Reference numeral 4 indicates a floor temperature detector that is attached to the floor surface B and detects the temperature of the floor surface B. Reference numeral 5 indicates a room temperature detector that is installed in the indoor space A and detects the indoor air temperature. Reference numeral 6 indicates the wall surface C of the indoor room A. A wall temperature detector 7 is attached to the wall to detect the wall surface temperature, and a wall temperature detector 7 adjusts and controls the above-mentioned floor surface constant temperature and indoor set temperature according to the detected wall surface temperature and temperature (and controls the indoor set temperature according to the detected floor surface temperature). A control device that controls the temperature setting of the floor surface according to the detected indoor temperature; and a control device that controls the supply Q of the hot air heater and the on/off of the solenoid valve 10 according to both the temperature settings. There it is,
It has control characteristics as shown in FIGS. 2 and 3.

, that is, 1. in FIG.
The vertical axis represents the indoor temperature, and the horizontal axis represents the floor surface temperature if.

: , that is, this ρ is controlled without worrying about the second part.
To explain, as the temperature of the indoor air increases, the amount of heat released from the human body by convection elements decreases, so that the floor surface temperature tf can be made comfortable even if it is low.

Also, for the same reason, if the floor surface temperature ff1f is high, the indoor air t
It can be seen that there is no need to make a very high.

If you connect these points that have the same pleasure, you will get a characteristic that slopes downward to the right as shown in Figure 2.

However, when the body temperature output f is low, the effect of radiation is small, so in the following cases, the floor surface temperature tf in the figure is set, and the indoor air ta is set at the upper limit of the comfortable temperature range and the indoor temperature set at 7 ta1. When the room temperature is constant, the characteristics of the above-mentioned negative slope are obtained up to the indoor air temperature and floor setting temperature shown in the figure.

Further, the room air ta and the floor surface temperature tf are controlled to have the characteristics shown in FIG.

In this figure, the vertical axis is the indoor air ta and the floor temperature tf, and the horizontal axis is the wall temperature tw.

As shown in the figure, as the wall temperature tw increases, the amount of heat dissipated by the radiant element decreases, so the indoor air ta and the floor temperature tf
can be made comfortable even if it is low, resulting in a negative slope.

In FIG. 2, twl and tw2 indicate wall surface temperatures, and tw is higher than twl.

Now, suppose that the heater is being operated at a point P0 consisting of the indoor set temperature ta24 and the floor set temperature tf2, then this point P0
When the wall surface temperature tw decreases from tw□ to tw□, tf rises due to the characteristics shown in FIG. 9, so the operating point moves to P1.

Similarly, when the wall temperature [w rises to tw, the room air ta and the floor temperature [tf] decrease, so the operating point moves to r2.

That is, due to a change in the wall surface temperature tw, the design temperature changes from P□ to P2.

Note that the above operation is performed at the set temperature ta2. Although the operation is performed at tf2, exactly the same operation is performed at other set temperature operating points.

There are two heaters in the bag, 1. w2t'>The operation will be explained.

As a result, P of the control characteristic curve ■ where the room air ta and the floor surface temperature tf have the same temperature sensation.

It will be controlled near the point. Furthermore, even if the wall surface temperature [w changes from the above value and the amount of radiant heat irradiated from the floor heater 1 to the human body changes, the control device 7 adjusts the control characteristic curve I accordingly to express the same temperature sensation. Control characteristic curve 1. , I

Since the control operating point is shifted to Pl and P2, the heating can be controlled to be comfortable in the same way as described above.

Although hot water is used as the heating heat source in the above configuration, a heat source other than hot water may be used, and the warm air heater and floor heater do not have to be operated together, but they can be switched and operated. Also good.

Furthermore, if the wall temperature detectors of the above embodiments are installed not only at one location but at several locations, the thermal sensation of the human body can be maintained more accurately.

Further, the configuration may be such that the operating points and control characteristic curves of the two heaters can be freely set within a range according to the user's preference.

As explained above, the heating device according to the present invention detects the temperature of the room, the floor surface, and the wall surface, controls the floor surface temperature setting and the room temperature setting according to the wall surface temperature, and also controls the indoor temperature setting based on the floor surface temperature. By controlling the set floor temperature with the room set temperature, it compensates for the human body's thermal sensation due to changes in wall temperature, while combining the quick heating and controllability of hot air heating and the comfort of floor heating with energy savings. The practical effects obtained by combining these characteristics are great.
