DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is an explanatory diagram showing an example of the configuration of an air-blowing heat storage system according to the present invention. Fig. 2 is an explanatory diagram of an air passage of the same air-blowing heat storage system.

[0015] The air-blow heat storage system 1 in the figure is for heating or cooling a floor surface 8 of a room 4 of a building, and heats or cools the floor surface 8 by hot or cold air.

[0016] For example, the room 4 shown in Fig. 1 is a room in a general house such as a private home or a building equivalent thereto, but it may also be in the form of a nursery room in a reinforced concrete nursery school building, and is not limited to a wooden house. The material of the floor surface 8 may be any material that allows the temperature of hot and cold air to easily be transmitted into the room 4. Also, there is no limitation based on the size of the room 4.

[0017] The air-blowing heat storage system 1 comprises an air-blowing source 40 that generates hot or cold air, an air-blowing means 42 that blows the hot or cold air, an air passage 10 that is arranged under the floor surface 8 and has at least one inlet 30 through which the hot or cold air is blown by the air-blowing means 42, and a pressure adjustment means 32 that adjusts the air pressure within the air passage 10.

[0018] 1, the air supply source 40 is, for example, an air conditioner, which is disposed on the ceiling 6, and an air outlet 40a, which is a normal outlet for hot or cold air of an air conditioner, is provided facing the inside of the room 4. In the present invention, in addition to the normal air outlet 40a, an air supply pipe 44 extends from the air supply source 40, and air supply means 42 is provided. The air supply means 42 is, for example, a fan, and may be anything that can efficiently blow hot or cold air.

[0019] An air duct 44 extends from the destination of the air blowing means 42 toward the floor surface 8. The air duct 44 is connected to the air passage 10 arranged below the floor surface 8.

[0020] The air passage 10, through which hot air or cold air is blown, has at least one inlet 30. To the inlet 30 of the air passage 10, an air blower pipe 44 extending from an air blowing means 42 is connected.

[0021] The ventilation path 10 is composed of a plurality of ventilation pipes 12, 14, 20, 22, 24, 26, and 28. Each of the ventilation pipes 12, 14, 20, 22, 24, 26, and 28 is tubular and communicates with each other. The shape of the ventilation path 10 may be changed arbitrarily depending on the planar extent and structure of the floor surface 8, and may be configured appropriately so as to effectively control the temperature of the floor surface 8 by hot and cold air.

[0022] However, in many cases, the planar extent of the floor surface 8 is rectangular, and in many cases, the form of the vent passage 10 is preferably such that the vent pipes 20, 22, 24, 26, 28 of the vent passage 10 are arranged parallel to each other, and each vent pipe 20, 22, 24, 26, 28 is connected to the other vent pipes 20, 22, 24, 26, 28, and each vent pipe 20, 22, 24, 26, 28 is in communication with each other. The vent pipes 20, 22, 24, 26, 28 are connected to each other at their ends by the vent pipes 12, 14, and are in communication with each other.

[0023] In the air-blowing heat storage system 1 of the present application, a pressure adjusting means 32 is provided for adjusting the air pressure in the air passage 10. In the air passage 10 of the present embodiment, as shown in FIG. 2, the pressure adjusting means 32 is provided at one end of the air passage 10.

[0024] The pressure adjusting means 32 may, for example, adjust the air pressure in the air passage 10 by exhausting hot or cold air from the air passage 10 when the air pressure in the air passage 10 reaches or exceeds a predetermined pressure, thereby lowering the air pressure in the air passage 10. Note that the pressure adjusting means 32 may be of any type as long as it is capable of adjusting the air pressure in the air passage 10.

[0025] When the pressure adjusting means 32 exhausts hot or cold air from the air passage 10 and lowers the air pressure in the air passage 10, for example, a filter having air permeability to a certain pressure can be used. Glass wool can be used as the material for this filter.

[0026] The operation of the air-blow heat storage system 1 having such a configuration will be described. First, hot or cold air generated by the air-blow source 40 is sent by the air-blow means 42 through the air-blow pipe 44 to the air passage 10. At this time, the hot or cold air is forced to be sent by the air-blow means 42, so that the air pressure of the hot or cold air is higher than the atmospheric pressure. Then, the air pressure of the hot or cold air sent into the air passage 10, which is in a nearly sealed state, is increased within the air passage 10.

[0027] The hot or cold air circulates through 12, 14, 20, 22, 24, 26, and 28 of the air passage 10. In the case of hot air, the air passage 10 is heated by the hot air, and the heat of the air passage 10 heats the floor surface 8. In the case of cold air, the air passage 10 is cooled by the cold air, and the cold heat of the air passage 10 cools the floor surface 8.

[0028] The air pressure in the air passage 10 is adjusted by a pressure adjusting means 32. When the pressure adjusting means 32 is glass wool, unnecessary hot or cold air is discharged to the outside of the air passage 10 through the glass wool.

[0029] The temperature of the hot or cold air may be, for example, about 60° C. at the air source 40 for hot air, and may be appropriately determined depending on the material of the floor 8 and the desired temperature of the room 4 (floor 8).

[0030] The air pressure inside the air passage 10 adjusted by the pressure adjusting means 32 is approximately 1.3 atmospheres as a guideline, but may be appropriately set depending on the material of the floor 8 and the desired temperature of the room 4 (floor 8).

[0031] According to the air-blow heat storage system 1 configured in this way, the floor surface 8 can be heated or cooled more efficiently by hot air or cold air.

[0032] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for the purpose of explaining the present invention and do not limit the scope of the present invention. That is, the scope of the present invention is indicated by the claims, not the embodiments. Various modifications made within the scope of the claims and within the scope of the meaning of the invention equivalent thereto are considered to be within the scope of the present invention.
