Description

[Detailed Description of the Invention] (Object of the Invention) The present invention relates to a new thermal energy supply system that uses an entire room in a building as a thermal energy generation room, and is particularly characterized by the method of utilizing the generated thermal energy. It is an attempt to provide a system.

(Prior art) Thermal energy supply systems for buildings that have already been developed by the applicant are, for example,
As seen in the invention of No. 58-27304, etc., it was a thermal energy supply system mainly intended for melting snow on roofs in cold and snowy areas such as the Tohoku region, so it was not possible to use wood burning stoves or other heating devices. In making full and effective use of the large amount of heat generated, there were some areas where the objective was not necessarily achieved.

In other words, even when there is no need to melt snow, such as when there is no snowfall or when it snows only a small amount during the day, there is no reason not to heat each room of the building. Therefore, the system was such that the heat dissipation device was operated as usual, and the generated thermal energy was supplied to spaces where it was not needed.

This invention was developed as a result of continuing research and development of a system that can deal with this situation and make more effective use of thermal energy, and has finally developed a new thermal energy supply system having the configuration as detailed below. This is what we have come to complete.

(Structure of the Invention) As can be clearly understood from the example of a building employing a system representative of this invention, which is shown in a partially perspective cross-sectional view, the thermal energy of this invention The supply system arranges a heating device 11 as appropriate in one room of the building to make the entire room a thermal energy generation room 1, and as necessary, connects the thermal energy generation room 1, solar heat absorption device 7, and geothermal absorption device. While connecting the thermal energy generation auxiliary device such as 8 etc., the thermal energy generation chamber 1 is connected to the piping 2.
In addition to communicating with each room 3, 3... of the building by other means, selective forced air can be applied to the roof eave space 4, the pipe section 5 on the road surface around the building, and the garbage dryer 6. It is characterized by the fact that it communicates with other people.

Thermal energy generation room 1 is a room in a building that is specially allocated as such, and if a new building is being constructed, a room with a specially planned structure as shown in the diagram is used. It is convenient to install it, and if it is built into an existing building, it can be appropriated by remodeling a storeroom, closet, or other small room.

This thermal energy generation chamber 1 is communicated with the space under the rim through piping 21, and air that is not susceptible to temperature changes from the outside throughout the year is taken in, also serving as intake air for the heating device. .

The heating device 11 is a specially designed stove, in addition to commercially available wood stoves, oil stoves, etc., and has a hot water storage chamber 13 connected to the water heater in the solar heat absorption device 7 in the peripheral area as shown in the example shown in the figure. It is possible to adopt a structure having two waste heat recovery devices 12 arranged in parallel. In the figure, 14 indicates a chimney for a heating device.

The piping 2 not only connects each room 3, 3... with the thermal energy generation room 1, but also connects the outdoor eaves 4, the pipes 5 on the street surface, and the garbage dryer 6 to each other so as to form independent paths. Thermal energy generation chamber 1
An appropriate type of pipe material such as plastic pipe or steel pipe is used.

However, although the piping 2 leading to each room 3, 3, etc. is not particularly required, the piping 22, 23, 24 leading to the roof eaves 4, the pipes 5 on the street surface, and the garbage dryer 6 must be installed at required locations (not shown). In this embodiment, forced fans 27, 28, and 29 must be independently combined at locations facing the thermal energy generation chamber 1, and each must be configured to operate selectively. Note that this selection requires the operation of the forced fans 27 and 28 in the roof eaves 4 and the pipes 5 on the street surface, and the operation of the garbage dryer 6.
It is extremely convenient from the viewpoint of thermal efficiency if the forced fans 29 are regulated so that they operate alternately, that is, when one is operating, the other is stopped.

For each room 3, 3... of the building, if it is adjacent to the thermal energy generation room 1, it should be installed directly without piping 2 (although it is possible to do so through a glazing door or other partition fittings to hide it). Although it is also possible to communicate with each other by means of piping 2, the communication is normally achieved through piping 2. On the other hand, if the room is not adjacent to the thermal energy generation room 1, then of course the piping 2 can be used to communicate with the room, or the piping 2 can be guided under the floor of the room to be connected to the branch pipe 25. Therefore, it is also possible to radiate heat energy throughout the underfloor space and to transmit heat energy from the periphery of the roof through the building materials. When adopting this latter method, it is convenient to plan the structure in advance so that the underfloor space is connected to the wall space, and furthermore, the wall space is connected to the ceiling, attic space, etc. is good.

From the piping 22 to the eaves pipe 4 on the roof eaves 4
Thermal energy is induced in the eaves pipe 41 and is released throughout the eaves space and the roof space through the small holes 42, 42, . . . of the eaves pipe 41. In the figure, 43 is an exhaust pipe for forcibly releasing moisture that fills the roof space due to dew condensation or the like.

The in-street pipe 5 is installed in advance in concrete in places such as entrance porches, walkways, parking lots, etc. around buildings where snow accumulation is a problem, and is installed in concrete for the thermal energy generation room 1. Circulating piping 23 is provided.

The garbage dryer 6 is communicated with the thermal energy generation chamber 1 through piping 24, and a damper or other backflow prevention device (not shown) is used in conjunction with the forced fan 29 to prevent odor backflow. is desirable. In the figure, 26 is an odor release pipe.

On the other hand, in the solar heat absorption device 7, which is a thermal energy generation auxiliary device, as described, the hot water is communicated with the hot water storage chamber 13 formed around the waste heat recovery device 12, and is used for thermal energy exchange in the thermal energy generation chamber 1. Although it is designed to work effectively,
Of course, it can be omitted depending on the case.

On the other hand, the geothermal absorption device 8, which is another thermal energy generation auxiliary device, stores filtered tap water, rainwater, and snowmelt water in a tank buried underground and absorbs geothermal heat. Heat is exchanged with the air in the pipe 81 passing through, and the heat energy is guided to the space under the edge of the building.
Furthermore, if necessary, it is also possible to forcibly lift the water in the tank, which has reached a predetermined temperature due to geothermal heat, to the roof and combine it with a solar heat absorption device to increase the rate of heat absorption. In the figure, 81 is a pipe that passes through the tank and reaches below the rim, 82 is a pump that forcibly lifts the water in the tank to the roof, and 9
is a rainwater filtration device, and 91 is a rain gutter.

(Operation and Effect) The system of the present invention, which has the following configuration, can be used, for example, when indoor heating is required, when it is necessary to remove snow from roofs and streets, and when it is necessary to dry food waste. At a certain time, a heating device 11 in a thermal energy generating chamber 1 specially provided in a corner of a building is activated to heat the air in the thermal energy generating chamber 1. At this time, since the structure is such that the air under the edge is always supplied into the thermal energy generation chamber 1 by the piping 21, the air inside the thermal energy generation chamber 1 can be raised within a short time. is possible. In particular, when a system for supplying thermal energy from the geothermal absorption device 8 is installed in parallel to the space under the edge, this heat increase efficiency becomes even more efficient.

Furthermore, in the case of the heating device 11 combined with the waste heat recovery device 12, the heat generated from the heating device 11 is not wastefully released to the outside and is efficiently used for heating the air inside the thermal energy generating chamber 1. Therefore, it becomes more economically efficient. In particular, when the waste heat recovery device 12 has hot water storage chambers 13 installed in parallel, this efficiency is further improved.

The air that has stored thermal energy in the heated thermal energy generating chamber 1 is supplied to each chamber 3, 3, etc. either naturally through the piping 2 or forcibly by a fan, producing an extremely comfortable heating effect. .

On the other hand, the roof eaves 4, the pipes 5 on the street surface, and the garbage dryer 6, which are connected to the thermal energy generating chamber 1 through pipings 22, 23, and 24, constantly supply heated air to the thermal energy generating chamber 1. Force fans 27, 28, which are selectively installed in each piping route, are used when necessary, such as when it is necessary to melt snow or dry food waste, etc. 29 is operated to receive the supply of heated air, which is extremely convenient in terms of effective use of heat. especially,
If the supply of thermal energy to the roof eaves 4 and the street pipes 5 and that to the garbage dryer 6 are regulated and planned so that they operate interchangeably, the effect is It becomes even more noticeable.

In other words, in an environment where there is no need to melt snow, the amount of heat required for indoor heating is generally small, and in such an environment, it is natural to reduce the amount of heat generated from the standpoint of economic efficiency. However, there are cases where the heating device 11 that generates a fairly large amount of heat calories is used and it is not possible to adjust the amount of heat very precisely, or there are cases where adjusting the amount of heat is not very difficult, but the time and effort required is better. In cases where this becomes a problem, it is possible to make effective use of heat by constantly using the excess heat energy to dry garbage.

As mentioned above, the heat supply system for a building according to the present invention has a thermal energy generation room as a specially partitioned room in one corner of the building, heats the entire space, and then distributes the heated air to each room. It can be supplied to roofs, eaves, streets, and/or garbage dryers for heating, snow removal, and other purposes, and unlike in the past, a separate heat source is not required for each purpose, which reduces equipment installation costs. It saves money and is easy to operate. In particular, it does not require any boiler or other special, complicated and expensive equipment as a heating device as a heat source.
It has the great feature that it can be used as is in either commercially available wood stoves or oil stoves.

Furthermore, when considering the fact that it can be systemized extremely easily by combining natural energy such as solar heat or geothermal heat absorbing equipment as needed, it is especially useful in the Hokuriku and Tohoku regions. It should be highly evaluated as an economical and efficient thermal energy supply system for buildings in snowy and cold regions.
