Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating system for heating a room by radiating heat from a radiator.

[0002]

2. Description of the Related Art Heating equipment includes a forced convection type having a fan for forcibly circulating indoor air and a natural convection type for circulating warm air without a fan by natural convection. The forced convection type heating equipment includes a fan heater and the like. Forced convection type heating equipment has high heating capacity,
There is also a disadvantage that the airflow is generated in the room and dust is blown. On the other hand, a natural convection type heating system includes a panel radiator (radiator) using heated water or the like as a heat medium. The natural convection heating system is sanitary with little dust.

FIG. 10 is a view for explaining the principle of a natural convection type heating system. A heat medium such as hot water generated by a heat source device (not shown) flows through the heat radiating pipe 110 such as a copper pipe or a resin pipe. The air around the heat radiating pipe 110 is heated by the heat medium in the heat radiating pipe 110. Since the density of the heated air decreases, a natural convection is generated by forming an ascending air flow as shown by an arrow in the figure. Therefore, the natural convection type heating equipment needs to have an air path in which the warmed air rises and moves away from the periphery of the heat radiating pipe 110, and substitute air is easily supplied around the heat radiating pipe 110.

FIG. 11 shows a configuration of a panel radiator 102 of a conventional natural convection type heating system. The panel radiator 102 is a wall-mounted type that is installed on a wall surface, and has a rectangular parallelepiped outer shape. A lower pipe of the panel radiator 102 is connected to an outgoing pipe 104 into which hot water flows and a return pipe 106 from which hot water flows. The hot water generated by the heat source device (not shown) flows into the panel radiator 102 from the outgoing pipe 104, flows through the heat radiating pipe 110, and flows out of the return pipe 106. Panel radiator 10
2 has an air inlet (not shown) on the lower surface. The air that has flowed in from the air inlet is heated by the heat radiating pipe 110 and rises, and flows out of the plurality of slits 108 formed on the upper surface of the panel radiator 102.

[0005]

SUMMARY OF THE INVENTION Panel radiator 10
The natural convection type heating equipment such as 2 has a lower heating capacity per size of the equipment as compared with the forced convection type heating equipment. In order to improve the heating capacity, it is necessary to increase the contact area (radiation area) between the radiation pipe 110 and air. In order to increase the heat dissipation area, the heat dissipation pipe 110 is lengthened, and as shown in FIG. 12, a heat dissipation fin 112 or the like is attached to the outer wall of the heat dissipation pipe 110. However, when the piping is lengthened, there is a problem that the heating equipment becomes large and the installation space increases. Further, if the heat radiating fins 112 and the like are attached to the outer wall of the heat radiating pipe 110, the size of the heating equipment can be relatively reduced, but there is a problem that the cost increases.

On the other hand, furniture and the like are arranged in the room, and the space for installing the heating equipment is limited, so that it is difficult to install a plurality of heating equipment. Therefore, the conventional heating equipment has a problem that temperature unevenness occurs in which the indoor temperature changes according to the distance from the heating equipment.

An object of the present invention is to provide a heating system that does not require a space for installing a heating facility and does not cause uneven temperature in a room.

[0008]

An object of the present invention is to provide a heating system having a radiator for radiating heat into a room, wherein the radiator is installed near a boundary area between a floor surface and a wall surface in the room. This is achieved by a heating system characterized by:

[0009] In the above heating system of the present invention, the boundary area is an area where a baseboard is installed. Further, in the above-mentioned heating system of the present invention, the radiator is stored inside the baseboard.

In the above-mentioned heating system of the present invention, the heating system further comprises a fan for forcibly convection the air. Alternatively, in the heating system of the present invention,
Further comprising a heat source device for heating the heat medium, the radiator,
The heat medium is a pipe through which the heat medium flows.

Further, in the above-mentioned heating system of the present invention, the heat medium is water. Alternatively, the heat medium is steam.
