Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat source unit for central heating including a fan convector (high temperature terminal) and a floor heating device.

[0002]

2. Description of the Related Art In the case of a conventional heat source unit for central heating, a heat exchanger, a gas burner, a cistern, and a circulation pump are built in the heat source unit, and a fan convector and a floor heating device in the room are hot water headers, respectively. Tied. FIG. 2 shows this conventional example, in which 1 is a heat source device, 2 is a fan convector, 3 is a floor heating device, 4 is a hot water header, and the hot water header 4 is composed of a forward 5 and a return 6 The vector 2 and the floor heating system 3 are connected to each other by a circulation line 7 called a pair tube.

In the case of the heat source unit 1 for central heating, the hot water header 4 is carried to the site as a component when the heat source unit 1 is installed, and after the heat source unit 1 is installed, it is attached under the heat source unit 1, respectively.

[0004]

Therefore, there are the following drawbacks.

A. Since the heat source machine is usually installed in a relatively low position and is often installed in a narrow space such as the pipe shaft of an apartment house,
Poor workability.

B. When installing a hot water opening / closing thermal valve (AC100V) in the header reaching the floor heating device 3, it is problematic to install the heat source device 1 and the thermal valve close to each other in the pipe shaft. When installing a thermal valve on the header, it must be done outside the pipe shaft. However, there are cases where the floor heating device cannot be installed because it is difficult to attach the thermal valve under various conditions.

An object of the present invention is to propose a heat source machine for central heating which has good workability and is devised so that there are no problems in disaster prevention.

[0008]

The structure of the heat source machine for central heating according to the present invention is as follows.

A hot header for the high temperature terminal, a return header for the high temperature terminal and a floor heating, and a header for the floor heating with a thermal valve are built in the bottom of the casing, and the hot water outlet side of the heat exchanger is connected to the hot header for the high temperature terminal. A high temperature terminal and a return header for floor heating are connected to a cistern, and the cistern and the inlet side of the heat exchanger are connected by a circulation line via a circulation pump, and a floor heating line is connected between the circulation pump and the heat exchanger of this circulation line. A heat source machine for central heating, which is branched from the floor heating line and connected to the floor heating forward header.

[0010]

[Operation] The high-temperature water produced by the heat exchanger in the heat source unit is branched to the fan convector side in each room at the hot header for the hot terminal, reaches the fan convector via the hot line for the hot terminal, and radiates heat there. It enters into the return header via the return line, where it merges and then enters the heat exchanger again via the cistern and circulation pump. On the other hand, in the case of the floor heating system, since low temperature water around 60 ° C is circulated,
The hot water returned from the cistern before entering the heat exchanger is guided to the floor heating upstream header via the floor heating line, reaches the floor heating device via the floor heating upstream line, and returns from the return header to the cistern. Leading to.

[0011]

EXAMPLE FIG. 1 shows a heat source machine according to the present invention. Reference numeral 10 denotes a casing that serves as an exterior of the heat source machine, and this casing is made of a metal hexahedron, and a heat exchanger 11,
A gas burner 12, a circulation pump 13, and a systern 14 are incorporated, and a hot header 15 for a high temperature terminal, a return header 16 and a floor heating forward header 17 with a thermal valve 18 are built in the inner bottom portion. In the figure, 19 is a hot water outlet line connecting the heat exchanger 11 and the high-temperature terminal outflow header 15, 20 is a return line connecting the return header 16 and the cistern 14, and 21 is a circulation line connecting the cisturn 14 → circulation pump 13 → heat exchanger 11. , 22 is a floor heating line that branches the circulation line 21 between the circulation pump 13 and the heat exchanger 11 and is connected to the floor heating outward header 17, 23 is a high temperature terminal outward line connected to a high temperature terminal, and 24 is A floor heating forward line connected to the floor heating apparatus, 25 is a high temperature terminal return line, and 26 is a floor heating apparatus return line.

The high temperature water produced by the heat exchanger 11 in the heat source unit 10 is branched to the fan convector side in each room by the high temperature terminal outward header 15 and reaches the fan convector via the high temperature terminal outward line 23. After radiating heat, the heat enters into the return header 16 via the high temperature terminal return line 25, where the post-merging systurn 14 and the circulation pump 13
Into the heat exchanger 11 via. On the other hand, in the case of the floor heating device, since the low temperature water of around 60 ° C. is circulated, the return hot water before entering the heat exchanger 11 from the cistern 14 is guided to the floor heating forward header 17 via the floor heating line 22. From there, it reaches the floor heating device via the floor heating forward line 24, returns from the floor heating return line 26 to the return header 16, and reaches the systern 14.

[0013]

As described above, the present invention has the following effects because each header is built in the casing of the heat source device.

A. When the heat source machine is produced in the factory, the header and the thermal valve can be installed in advance and shipped, so that there is no need to attach the header at all in the field.
Therefore, the workability is improved.

B. By installing a thermal valve on the floor heating forward header and taking the power source of this thermal valve from the heat source machine side, it is possible to eliminate the obstacles in construction and disaster prevention due to the installation of the thermal valve.
