JPH07259283A - Heat collecting and radiating device for roof - Google Patents

Abstract

PURPOSE:To collect heat at the time of fine weather and heat roofing material at the time of snowfall by constructing heat collecting-radiating plates under the roofing material, connecting them to a heat accumulating tank through piping, controlling each radiating plate by a valve to circulate a liquid heat medium, and radiating as occasion calls. CONSTITUTION:At the time of collecting solar heat, heat is accumulated in a heat accumulating tank 8 by a liquid heat medium through piping constructed at roofing material 2 and glass 3 and radiated from a jointless radiating pipe 4 under the floor or the like for heating. When heat cannot be collected, heating is performed by the liquid heat medium heated by a heating device 7 connected to the heat accumulating tank 8. At the time of snowfall, the liquid heat medium is reversely circulated to the piping under the roofing material 2 from the heat accumulating tank 8, and the roofing material 2 is heated to melt and discharge snow. The road surface is further heated by the liquid heat medium circulated from the heat accumulating tank 8 to piping buried under the road surface at the entrance of a house to melt snow. The temperature control of each part is performed by an adjustable thermo-controller.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to home solar systems.

[0002]

2. Description of the Related Art Conventionally, there is known a floor heating system in which a liquid heat medium heated by a heat collecting plate mounted on a roof is stored in a heat storage tank and is then supplied to each radiator to be used as a heat source.

[0003]

The conventional solar system has the following drawbacks. (1) Since the heat collecting plate is installed on the roof, the load is locally applied to the roof. (2) Not available during snowy season.

[0004]

[Means for Solving the Problems] Instead of a heat collecting plate, piping is installed under a certain portion of the roof material of the roof, and a part of the roof material is replaced with glass. A heat storage tank is further connected to a heating device through a pipe provided under the roofing material, and a device for circulating a liquid heat medium in this pipe is provided. On the other hand, a heat sink is installed under the floor of the room or in a necessary place from the heat storage tank.

[0005]

In this plan, since the above measures are taken, on a sunny day, the heat collected from the heat radiating plate can be collected from the heat radiating plate. Dissipate heat and use. During snowfall, the roof material is heated by circulating a liquid heat medium heated by a heating device on the heat collecting and radiating plate on the roof, and the snowfall is used for snowfall.

[0006]

【Example】

(1) When the solar heat can be collected, the heat collected through the piping installed on the roofing material and the glass is stored in the heat storage tank by the liquid heat medium, and is piped from here to under the floor and other places where heating is required. Heat is dissipated from the seamless radiating pipe to heat the floor. (2) When solar heat cannot be collected, heating is performed by the liquid heat medium heated by the heating device connected to the heat storage tank. (3) During snowfall, the liquid heat medium is circulated from the heat storage tank to the pipe under the roof material to heat the roof material to melt the snow and snow. (4) Snow is melted by heating the road surface with the liquid heat medium circulated from the heat storage tank in the pipe buried in the road surface at the entrance. (5) The temperature of each part is controlled by an adjustable thermo controller.

[0007]

The embodiments shown in the drawings will be described in more detail below.

When the solar heat can be collected, the heat collected by the heat radiation plates (1) and (6) is circulated by the circulation pump (11) through the roof material (2) or the glass (3) heated by the solar heat. The liquid heat medium is collected in the heat storage tank (8), and the underfloor heating plate (4) and other valves (1
Circulate by controlling in 6).

When the heat cannot be collected due to cloudiness, the liquid heat medium in the heat storage tank (8) is heated by a heating device (7) such as a boiler, and this is passed through a valve (16) by a circulation pump (11) to each heat radiating plate. Send it to and radiate it.

When snow falls, the snow on the roof material (2) is circulated from the heat storage tank (8) to the heat radiating plates (1) and (6) through the valve (16) by the circulation pump (11) to heat the roof material. This heat causes snow to fall or melt.

A heat radiating plate (5) is embedded in the road surface at the entrance, and a liquid heat medium is circulated in the heat radiating plate (5) to melt the snow on the road surface.

Each valve (16) is controlled by each sensor (17) or switch according to the weather.

A heat radiating plate (1) and a floor heating radiating plate (10)
Insulation material (9) with a groove to bury this pipe underneath
(10) is applied.
