Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air heating device that circulates hot water and supplies hot air through heat exchange between the hot water and an air flow generated by a blower.

This kind of hot air heating equipment produces hot water with a heating boiler,
The hot water is circulated and supplied to the heat exchanger by a circulation pump, and a blower is used to blow air to the heat exchanger for heat exchange and to blow hot air into the room.

A common method for controlling the room temperature is to use a room temperature controller to change the output of a blower to change the amount of air.

However, in the case of conventional equipment, the hot water temperature remains constant even if the air volume changes due to fluctuations in the output of the blower, so the temperature of the hot air blown out becomes high when the air volume is low, and the blown air speed is also low. As a result, the draft force is stronger than the forced circulation force caused by the hot air blowing force indoors, and a temperature difference occurs between the upper and lower parts of the room, or between the vicinity of the heating device and a distant place, resulting in extremely poor temperature distribution in the room. It had the disadvantage of being

The present invention was developed in view of the above-mentioned circumstances, and provides a heating device that eliminates the drawbacks of the conventional system by simultaneously lowering the temperature of circulating hot water when the amount of air blown by the blower is reduced according to the room temperature. The purpose is to

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a hot air supply unit equipped with a blower 2 and a heat exchanger 3 consisting of a group of pipes through which hot water flows, 4 is a heating boiler that generates hot water, and 5 is a hot air supply unit that generates hot water in the boiler 4. A hot water temperature controller for setting the temperature, 6 a circulation pipe connecting the heat exchanger 3 and the boiler 4, 7 a hot water circulation pump installed in a circulation vibro, 8 a room temperature controller, and a blower 2. It is electrically connected to the hot water temperature controller 5 of the boiler 4, and when the sensed room temperature reaches the set temperature, an output signal is sent to adjust the amount of air blown by the blower 2 and the hot water boiling temperature of the boiler 4.

The operation of the hot water heating device having such a configuration will be explained.

At the beginning of heating, there is a large temperature difference between the set temperature of the room temperature controller 8 and the room temperature, and the output of the blower 2 is increased to increase the amount of air blown. The hot air supply unit is set at a high temperature of about 100°C, and the high-temperature hot water is produced in the boiler 4, and is supplied to the heat exchanger 3 as shown by the arrow in the figure by the hot water circulation pump 5 via the circulation vibro. 1 blows relatively high-temperature warm air into the room, and the room temperature quickly rises and approaches the set temperature of the room temperature controller 8.

When the room temperature reaches the set temperature, the output signal from the room temperature regulator 8 is used to reduce the output of the blower 2 to reduce the amount of air blown.

At the same time, an output signal is sent from the room temperature controller 8 to the hot water temperature controller 5, and the hot water boiling temperature is automatically switched to a low temperature of, for example, 50°C, so the temperature of the hot air blown out is relatively low. The temperature becomes low.

For this reason, due to a decrease in the amount of air blown as in the past, the blower 2
It is possible to prevent the phenomenon in which the draft force of hot air exceeds the forced circulation force of the heated air, making it possible to make the indoor temperature distribution approximately equal, and providing a comfortable heated space.

As described above, according to the present invention, the hot water temperature decreases at the same time as the amount of air blown by the blower decreases, and high temperature hot air is not blown out when the hot air blowing speed is low, so the draft force of the hot air is reduced. The forced circulation force of the blower is always greater than that of the air conditioner, which improves the temperature distribution in the room and provides a comfortable heated space.
