Abstract

PURPOSE:To obtain an effective space-heating apparatus which is capable of heating a space to be air-conditioned promptly, by using a floor heating apparatus and a high-temperature radiation heating apparatus in combination. CONSTITUTION:In case that the temperature of air detected by a room-temperature detector 3 is higher than a prescribed value at the initial stage of space- heating operation or when the room temperature is lowered during space-heating operation by disturbance such as abrupt drop of the atmospheric temperature or increasing of the ventilating rate, an ON control signal is given from a voltage comparator 6 constituting a control unit 4 to a power circuit 7 for an electric stove and a high-temperature radiation heating apparatus 2 consisting of an electric stove is set into operation. Through operation of the high-temperature radiation heating apparatus 2, the temperature of air in a room to be air-conditioned is raised. When the temperature of air in the room becomes higher than a prescribed value, an OFF control signal is given from the voltage comparator 6 to the power circuit 7 to stop operation of the high-temperature radiation heating apparatus 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating system that combines a floor heating system and a high-temperature radiant heating system.

Conventional configuration and its problems Generally, heating in floor heating systems is radiant heating, so
It is an energy-saving and comfortable heating method that does not require the room temperature to be raised to an extreme level and causes little variation in indoor temperature distribution. The heating in this floor heating system is said to be an ideal surface heating method, without the discomfort caused by the warm air directly hitting the occupants themselves, which is the case with convection heating.

However, the start-up of floor heating is very slow at the beginning of heating, and it takes a long time to provide a sufficient sense of warmth to the occupants. This shows a comparison of a stove, a hot air fan, and a floor heating system. As is clear from this figure, floor heating systems are much slower to heat than electric stoves, which provide high-temperature radiant heating. Furthermore, this floor heating system had a slow response speed to disturbances during heating, such as a sudden drop in outside temperature or an increase in the amount of ventilation.

OBJECTS OF THE INVENTION The present invention solves the two problems of the prior art, and aims to provide a comfortable heating system that quickly starts up without losing the advantages of floor heating.

Structure of the Invention In order to achieve the above object, the present invention includes a floor heating device, a high-temperature radiant heating device, a room temperature detector that detects an air temperature of 3.0 degrees Celsius in a space to be heated, and and a control device that operates the high-temperature radiant heating device only when the air temperature is below a predetermined value. According to this configuration, the high-temperature radiant heating device such as an electric stove is activated at the beginning of heating or when the room temperature drops due to disturbance. As the heating system operates, it is possible to rapidly increase the feeling of warmth in the occupants, and as a result, it is possible to obtain a comfortable heating system that is energy-saving and energy-saving, and has a quick start-up time.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In Fig. 2, 1 is a floor heating device made of an electric carpet, 2 kJ is a high-temperature radiant heating device made of an electric stove, 3 is a room temperature detector that detects the air temperature in the space to be covered, and 4 is a This control device 4 is electrically connected to the floor heating device 1 and the room temperature detector 3.
is configured to operate the high-temperature radiation device 2 formed by the electric stove only when the air temperature detected by the detector 3 in the room 11 is below a predetermined value J.

FIG. 3 shows a control block diagram in the above-mentioned embodiment, and the same numbers as in FIG. 2 indicate the same parts, so the explanation thereof will be omitted.

In FIG. 3, 5 is a reference voltage generator that generates a reference voltage according to a predetermined value of the room temperature, and 6 is a reference voltage generator that compares the detection signal from the room temperature detector 3 with the reference signal from the reference voltage generator 5. , 0N-OFF to electric stove power supply circuit 7
It is a voltage comparator that sends control signals.

The operation in the above configuration will be explained. When the air temperature detected by the room temperature detector 3 is below a predetermined value at the beginning of heating or when the room temperature drops due to a disturbance during heating such as a sudden drop in outside temperature or an increase in ventilation volume, the control device 4 An ON control signal is sent from the voltage comparator 6 to the electric stove power supply circuit 7, and the high temperature radiant heating device 2, which is an electric stove, is activated. This operation causes the indoor air temperature to rise, and when the air temperature exceeds a predetermined value, the voltage comparator 6 sends an OFF control signal to the electric stove power supply circuit 7, and the electric stove 5' The operation of the high-temperature radiant heating device 2 is stopped.

Note that the floor heating system 1 made of an electric carpet is always energized after heating starts. By having the configuration as shown in (g), as is clear from Fig. 1, the start-up of the electric stove is reduced. This function can rapidly increase the sense of warmth in the occupants during the initial stage of heating, and also maintain the occupants' sense of warmth even when the room temperature drops due to disturbances during heating, such as a sudden drop in outside temperature or an increase in the amount of ventilation. It has the excellent effect of rapidly restoring the sense of warmth.

Effects of the Invention As is clear from the above description, the heating device of the present invention includes a floor heating device, a high-temperature radiant heating device, a room temperature detector that detects the air temperature of the space to be heated, and and a control device that operates the high-temperature radiant heating device only when the air temperature is below a predetermined value. It can rapidly increase the feeling of warmth in the occupants, and therefore has the excellent effect of enabling speedy heating without sacrificing energy saving and comfort, which are the advantages of floor heating on page 6. It is something.
