Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a wooden house,
The present invention relates to a solar system that uses solar energy to heat a living room.

[0002]

2. Description of the Related Art In winter, a solar system that stores heat from solar energy in the daytime and is used for heating living rooms at night does not pollute the environment and is a safe and clean energy-saving system. ing.

As a so-called solar house provided with such a solar system, there is, for example, the one shown in FIG. In the illustrated solar house D, a heat insulating material frame 61 is arranged in an area surrounded by a cloth foundation 60 under the wall of the building, and crushed stones are filled to form a rock bed 62. Floor concrete is placed on the rock bed 62. A slab 63 is cast and formed in the heat storage tank 64. A two-story wooden house is built on the cloth foundation 60 according to a general construction method, but the floor of the living room on the first floor is the floor concrete slab 63.
A floor carpet 65 is laid on and finished.

Further, a box-shaped collector 67 whose surface is covered with a glass plate is provided on the roof 66 on the south side.
The air warmed by solar heat inside is supplied into the heat storage tank 64 via a duct 69 provided with a fan 68,
The heat is transmitted to the lock bed 62 to store the heat. Further, the exhaust air from the heat storage tank 64 is introduced into the living room through an exhaust port 70 provided on the side opposite to the duct 69 side. The heat stored in the lock bed 62 is dissipated through the floor concrete slab 63 at night when the temperature is lowered to warm the living room.

[0005]

However, in this solar house D, in addition to the fans and ducts, a special large-sized heat radiation opening for opening hot air into the atmosphere in the summer is provided on the roof surface. It cannot be said that the equipment is necessarily simple because it requires the installation of a heat collector, special installation work for it, and the installation work of the heat storage tank in addition to the construction work of the building. Further, there is a problem in economic efficiency such that a relatively large fan is required in terms of load due to air circulation and ventilation resistance of the lock bed in the heat storage tank. Further, in this solar house, since the heat storage tank is installed only under the first floor, there is a problem that the warm air does not reach the living room on the upper floor such as the second floor.

In view of the above problems, the present invention is an economical system in which the equipment and its installation work can be minimized, the heat utilization efficiency is high, and the living room on the upper floor such as the second floor and the third floor is high. The challenge is to provide a solar system that can also be applied to.

[0007]

In order to solve the above-mentioned problems, the present invention provides a wooden house in which the floor set is made of plate-like concrete and the plate-like concrete is used as an indoor heat storage material for indoor heating. In the solar system, the floor set is composed of plate-like concrete, and a space having the plate-like concrete as one side is formed, and one end is opened at a place where the sunlight warm air stays inside the building, A duct having the other end opened is disposed on the duct, and a fan is provided in the duct. The fan warms the sunshine warm air and supplies it to the space, and the plate-shaped concrete is used as a heat storage material. A solar system in a wooden house used for indoor heating, wherein the space is a space formed between the plate concrete and a double floor laid on the plate concrete. A solar system for a wooden house, and further a solar system for a wooden house, in which the space is a space formed by the foundation of the building and plate-like concrete on the first floor. is there.

[0008]

[Operation] During the winter, sunlight warms the indoor air through the windows during the day, and heat is stored in the plate-like concrete of the floor assembly incorporated as a structural frame. When the temperature drops at night or the like, heat is gently dissipated from these plate-like concretes to heat the room.

Further, when the roof surface is warmed by the sunlight, sunshine warm air stays in the back of the hut, and the indoor air warmed through the window stays as sunshine warm air near the indoor ceiling due to convection. When the fan of the duct that opens at such a place where the sunshine warm air is accumulated is operated, the sunshine warm air passes through this duct and forms an underfloor space formed by the building foundation and the floor group, and between the floor group and the double floor. Since it is supplied to the above-floor space, etc., which is formed by, the heat is stored in the plate-like concrete of the floor set, and when the indoor temperature drops, the heat is gently dissipated from this plate-like concrete through the floor finishing material. , Indoor heating is performed.
