Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-circulating air-conditioning type floor heating system house which can realize floor heating for the entire floor of a house and efficiently heat and ventilate the room.

[0002]

2. Description of the Related Art Conventionally, heating equipment such as an oil stove and an air conditioner has been used in winter to warm a room to a comfortable temperature. In addition, central heating, which installs a heating device in one part of the building and supplies hot air or hot water to each room, is also used.

[0003] However, recently, as a more comfortable indoor heating means, a floor heating system has been developed in which a heating facility is incorporated in a floor structure and the floor surface is heated by radiant heat.
As a floor heating system, a system using an electric heating effect is generally well known. However, as described in Japanese Patent Publication No. 3-48299, the floor heating system uses solar energy to generate hot air through a floor panel. Floor heating systems that directly heat the floor are also known.

[0004]

However, in the conventional floor heating system that heats from the floor, heating at the feet can be obtained, but it takes a considerable amount of time to raise the temperature to the room temperature, and the oil stove and the like are not heated. Heating equipment such as an air conditioner had to be used together.

Further, the floor heating system described in Japanese Patent Publication No. 3-48299 uses solar energy, so that a sufficient heating effect may not always be obtained. Without it, comfortable heating during the winter months would not be possible.

An object of the present invention is to provide an air circulation type air-conditioning type floor heating system house which realizes floor heating with excellent economy without polluting indoor air during heating. Another object of the present invention is to realize economical cooling and dehumidification without polluting indoor air with the same system.

[0007]

In order to achieve the above object, an air circulation type air-conditioning type floor heating system house of the present invention comprises an outside air inlet and an outside air outlet, and the outside air introduced from the outside air inlet. A heat exchange type ventilation fan that exchanges heat with the air exhausted from the outdoor exhaust port, and a fan that sends the heat-exchanged outside air through a duct to an air flow path formed under the floor and draws indoor air on the ceiling An air-conditioning ventilator that blows air to the heat-exchange type ventilation fan through a duct, and a hot-air outlet that is blown under the floor and blows out air to be used for floor heating into the room, and is provided in a floor panel at an indoor corner, is provided. It is characterized by the following. With the above configuration, the air introduced from the outside air inlet and warmed can be used for floor heating, and the air is simultaneously blown into the room through the warm air outlet of the floor panel, and the indoor air is further sucked into the ceiling suction duct. By discharging the air to the outdoor exhaust port through the air, the floor and the room can always be heated using clean air, and the floor heating excellent in economic efficiency can be realized.

In the present invention, the heating effect can be further enhanced by installing a hot air blower for warming the air blown under the floor in the air pit formed under the floor.

Further, in the present invention, the floor heating can be performed more efficiently by covering the bottom surface and side surfaces of the air pit and the wall surfaces of the underfloor space with heat insulating material.

Further, in the present invention, the air-conditioning ventilator blows air into the room through the suction duct installed on the ceiling while cooling and / or dehumidifying the heat-exchanged outside air, and also removes indoor air. By having a function of sucking air from the duct under the floor through the warm air outlet and sending air to the heat exchange type ventilation fan, the same system can also perform cooling.

[0011] Charcoal, wood chips,
By laying crushed stones or a mixture thereof, it is possible to obtain not only an air purification but also a humidity control effect and a heat storage effect.
