  In the conventional heating device, a space different from the space to be heated is heated by heat radiation from the heat medium return pipe. It may not be possible to heat a space other than the target space well, and the amount of heat released to a space other than the space to be heated can be increased so that a space other than the space to be heated can be heated well. It was hoped to do.

  This invention is made | formed in view of this situation, The objective is providing the heating apparatus which can heat the space different from the heating object space favorably, while heating the heating object space appropriately. It is in.

The heating device of the present invention includes a heating terminal for heating a space to be heated,
A heat medium forward pipe for supplying a heat medium from a heat source machine to the heating terminal;
A heating medium return pipe for returning the heating medium that has passed through the heating terminal to the heat source machine;
In the first characteristic configuration, the heating medium return pipe and the heating medium return pipe are arranged on a floor portion of a space different from the space to be heated, and the heating medium return pipe is more on the floor than the heating medium return pipe. It is arranged in a form that easily dissipates heat on the upper surface side of the part ,
A piping member formed in a state having a concave return pipe groove on the upper surface and a concave forward pipe groove on the lower surface is provided on the floor base in a floor different from the space to be heated, and on the floor base It is provided between the floor finishing material located above and forming the upper surface of the floor part,
In the form in which the heat medium return pipe and the heat medium return pipe have the heat medium return pipe embedded in the return pipe groove of the piping member and the heat medium return pipe embedded in the forward pipe groove of the piping member. It is in the point where it is arranged .

In other words, the heat medium return pipe and the heat medium return pipe are radiated to the floor of a space different from the space to be heated, and the heat medium return pipe is more likely to radiate heat to the upper surface side of the floor than the heat medium forward pipe. Therefore, the retained heat of the heat medium flowing through the heat medium return pipe is radiated from the heat medium return pipe to the upper surface side of the floor portion of the space different from the space to be heated, and the heat medium return pipe However, although it is more difficult to dissipate heat than the heat medium return pipe, the retained heat of the heat medium flowing through the heat medium forward pipe is radiated to the upper surface side of the floor portion in a space different from the space to be heated.
In other words, since heat is radiated from both the heating medium return pipe and the heating medium return pipe to a space other than the space to be heated, the amount of heat released to a space other than the space to be heated can be increased, and the heat Since the medium return pipe can efficiently dissipate heat to the upper surface side of the floor portion, the amount of heat released to a space other than the space to be heated can also be increased from this point. It is possible to heat a different space with a sufficient amount of heat radiation.
Also, although heat is dissipated to the upper surface side of the floor by the heat medium forward pipe, the heat dissipation is difficult to be performed compared to heat radiation from the heat medium return pipe to the upper surface side of the floor. The temperature of the heating medium supplied to the heating terminal through the heating terminal can be suppressed from decreasing until the heating terminal affects the heating of the heating target space, and the heating terminal heats the original heating target space. It is possible to appropriately heat the space to be heated by suppressing the influence on the space.
Incidentally, in general, the floor base part that constitutes the lower part of the floor part insulates the upper side of the floor base part from the lower side of the floor base part. Heat radiation from the return pipes to the floor is suppressed.
Therefore, it has become possible to provide a heating device that can appropriately heat a space to be heated and that can favorably heat a space other than the space to be heated.

Further, according to the first characteristic configuration , the heating medium is returned to the concave return pipe groove on the upper surface of the piping member provided between the floor base and the floor finishing material of the floor different from the space to be heated. The heat medium forward pipe and the heat medium return pipe are disposed in a form in which the pipe is buried and the heat medium forward pipe is embedded in the concave forward pipe groove on the lower surface of the piping member, so that the heat medium forward pipe is provided. The pipe and the heat medium return pipe are arranged on the floor of a space different from the space to be heated in a form in which the heat medium return pipe is more likely to radiate heat on the upper surface side of the floor than the heat medium forward pipe. Become.
That is, the heat medium return pipe embedded in the concave return pipe groove on the upper surface of the piping member efficiently dissipates heat to the upper surface side of the floor finishing material through the floor finishing material above the piping member. From the heating medium forward pipe embedded in the concave forward pipe groove on the lower surface of the member, heat is radiated to the upper surface side of the floor finishing material through the piping member and floor finishing material. The space can be heated well.
In addition, heat radiation to the upper surface side of the floor finishing material by the heat medium return pipe is performed through the floor finishing material, whereas heat radiation to the upper surface side of the floor finishing material by the heat medium return pipe is performed through the piping member and floor finishing material. By doing so, heat radiation to the upper surface side of the floor finishing material by the heat medium return pipe is difficult to be performed compared to heat radiation to the upper surface side of the floor finishing material by the heat medium return pipe, It is possible to appropriately heat the heating target space by suppressing a decrease in the temperature of the heating medium supplied to the heating terminal through the heating medium forward pipe.

The operation of arranging the heat medium forward pipe and the heat medium return pipe on the floor portion is, for example, arranged on the floor base portion with the piping member placed in the forward pipe groove portion on the lower surface of the heat medium forward pipe. Subsequently, the heat medium return pipe is embedded in the return pipe groove on the upper surface of the pipe member. By using such a pipe member, the heat medium forward pipe and the heat medium return pipe are It is possible to facilitate the work of arranging the heat medium return pipe on the floor of a space different from the space to be heated in a form in which it is easier to dissipate heat on the upper surface side of the floor than the heat medium forward pipe.
Therefore, in addition to the above effects , it is possible to obtain an effect that the construction work can be facilitated.

The second characteristic feature, in addition to the first feature structure,
The heating medium return pipe is arranged in a straight line on a floor portion in a space different from the heating target space, and the heating medium return pipe is arranged in a meandering manner in a floor portion in a space different from the heating target space. It is in the point.

That is, the heat medium forward pipe is arranged in a straight line on the floor portion of the space different from the space to be heated, and the heat medium return pipe is arranged in a meandering manner in the floor portion of the space different from the space to be heated. Therefore, the length of the heat medium return pipe from the heat source unit to the heating terminal can be shortened as much as possible, and the length of the heat medium return pipe in the floor of the space different from the space to be heated can be made as long as possible. .
In this way, by reducing the pipe length of the heat medium forward pipe from the heat source unit to the heating terminal as much as possible, the heat radiation amount from the heat medium forward pipe to the upper surface side of the floor is allowed as much as possible. The floor part of the space different from the space to be heated can be reduced, while suppressing the influence on the heating of the space to be heated, while assisting the heating of the space other than the space to be heated. By making the pipe length of the heat medium return pipe as long as possible, the heat radiation from the heat medium return pipe to the upper surface side of the floor is increased as much as possible, and a space other than the space to be heated is more effectively Can be heated.
Therefore, while the space to be heated can be appropriately heated, a space other than the space to be heated can be heated even better.

  In other words, the heat medium forward pipe 1 and the heat medium return pipe 2 are each embedded in the piping member 3 configured as described above, so that the heat medium forward pipe 1 is in the space to be heated. The heating medium return pipe 2 is arranged in a meandering manner in the floor part f of the space C, D different from the heating target space L. In this way, the heating medium return pipe 1 and the heating medium return pipe 2 are arranged in this manner, so that the heating medium return pipe 2 is more floor than the heating medium return pipe 1. It will be arranged on the upper surface side of f in a form that facilitates heat dissipation.

Next, explanation will be given on the floor portion f of the house.
As shown in FIG. 3 and FIG. 4, the floor foundation 4 of the floor f includes a floor foundation substrate 41, joists 42 juxtaposed on the upper surface of the floor foundation substrate 41, and a floor foundation substrate 41. The floor heat insulating material 43 provided between the adjacent joists 42 on the upper surface of the floor and the floor base upper plate 44 provided on the joists 42 provided side by side on the floor base substrate 41.
The floor heat insulating material 43 is made of a heat insulating material such as glass wool having a low thermal conductivity.
That is, the floor foundation part 4 is configured to have heat insulation properties by sandwiching the heat insulating material 43 between the floor foundation upper plate 44 and the floor foundation substrate 41 as described above.
The heating medium return pipe 1 and the heating medium return pipe 2 embed the heating medium return pipe 2 in the return pipe groove 32 of the piping member 3 and the heating medium return pipe 1 for the outgoing pipe of the piping member 3. Since it is embedded in the groove 31, it is provided between the floor foundation 4 and the floor finishing material 5 in the floor part f of the dressing room D and the corridor C, which are different from the living room L as the space to be heated. The heating medium return pipe 1 and the heating medium return pipe 2 are arranged on the floor part f of the space C, D different from the heating target space L in the heating medium return pipe 2 than the heating medium return pipe 1. This is arranged in a form that is easy to radiate heat on the upper surface side of the floor part f and in a form that is difficult to radiate heat to the lower side of the floor part f.

  The floor finish 5 is made of a flooring material or the like, and the upper surface of the floor finish 5 is the upper surface of the floor portion f.

Next, a procedure for installing the heating apparatus configured as described above will be described.
First, two floor heating panels P are laid side by side on the floor base 4 in the floor f of the living room L.
Subsequently, the two pipe members 3 are placed along the piping path of the heat medium forward pipe 1 and the heat medium return pipe 2 in a state where the heat medium forward pipe 1 is embedded in the forward pipe groove portion 31 on the lower surface thereof. Thus, the floor part f of the dressing room D and the floor part f of the hallway C are laid side by side.
Subsequently, the heat medium return pipe 2 is embedded in the return pipe groove 32 on the upper surface of the two pipe members 3 laid as described above, and then the heat medium return pipe 32 is placed in the return pipe groove 32 as such. Is attached to the upper surface of the piping member 3 in a state where is embedded.
Subsequently, the end of the heat medium forward pipe 1 on the side of the heat source machine and the end of the heat medium return pipe 2 on the side of the heat source machine are respectively the outlet for the heat medium delivery of the heat medium passage in the heat source machine, and for the return of the heat medium Connect to the entrance.
Further, the end of the heating medium outlet pipe 1 on the floor heating panel side is connected in parallel to the heating medium inlet in the header 24 of the two floor heating panels P, and the floor heating panel of the heating medium return pipe 2 is connected. The end on the side is connected in parallel to the heat medium exhaust outlet in the header 24 of the two floor heating panels P.
Subsequently, the floor finishing material 5 is laid on the floor portion f of each of the living room L, the hallway C, and the dressing room D.

Next, the heating effect | action of the heating apparatus comprised as mentioned above is demonstrated.
When the heat source machine G is operated, the heat medium heated to, for example, 60 ° C. by the combustion heat of the gas burner in the heat source heat exchanger of the heat source apparatus G passes through the heat medium forward pipe 1 and the heat medium return pipe 2. The floor heating panel P is circulated and supplied, and the heat stored in the heat medium flowing through the heat medium flow pipe 22 is radiated from the floor heating panel P to heat the living room L.
In addition, the retained heat of the heat medium flowing through the heat medium return pipe 2 is radiated from the heat medium return pipe 2 to the upper surface side of the floor part f of the dressing room D and the corridor C, and also from the heat medium return pipe 1. Although it is more difficult to dissipate heat than the heat medium return pipe 2, the retained heat of the heat medium flowing through the heat medium forward pipe 1 is dissipated to the upper surface side of the floor part f of the dressing room D and the corridor C. The room D and the hallway C can be heated well.
Moreover, the heat medium return pipe 2 is arranged on the upper surface of the piping member 3, and the heat medium return pipe 2 is arranged in a meandering manner on the floor f of the dressing room D and the corridor C. In addition, since the length of the heat transfer pipe 2 in the floor f of the corridor C and the floor f of the corridor C can be made as long as possible, the heat medium return pipe 2 is used to bring the dressing room D and the corridor C to the upper surface side of the floor f. Since heat can be efficiently radiated and heat radiation from the heat medium return pipe 2 can be further promoted by the heat equalizing sheet 6 attached to the upper surface of the piping member 3, the dressing room D and the corridor C Can be heated more satisfactorily.

  In addition, although the heat medium forward pipe 1 radiates heat to the upper surface side of the floor part f, the heat radiation is difficult to be performed compared to the heat radiation from the heat medium return pipe 2 to the upper surface side of the floor part f. The temperature of the heat medium supplied to the floor heating panel P through the heat medium forward pipe 1 can be suppressed from being lowered, and the living room L can be appropriately heated by the floor heating panel P.

Moreover, since the amount of heat radiation from the heat medium flowing through the heat medium forward pipe 2 can be increased, the temperature of the heat medium returning to the heat source heat exchanger of the heat source machine G can be reduced as much as possible. Heat exchange efficiency in the heat exchanger for heat source can be improved and heating efficiency can be improved.
Incidentally, for example, the heat medium sent from the heat source machine G at 60 ° C. can be lowered to 50 ° C. and returned to the heat source machine G.
