Description

  The present invention relates to a building heating / cooling device and a heating device, and more particularly to a floor surface or under-floor heating / cooling device and a heating device.

Heating by heat radiation from the floor surface is comfortable in terms of experience, and so-called “floor heating” in which a heating element is provided inside the floor is widely used.
Recently, so-called “underfloor heating” is also being adopted in which heat obtained by using cheap late-night electricity is stored in the soil or air under the floor, and is radiated naturally throughout the day and night. Underfloor heating uses cheap late-night power, not only is the running cost cheaper, but it is also easier to install heat medium piping and the initial cost than floor heating. (For example, refer to Patent Document 1).

In addition, as a conventional underfloor heating device, the underfloor space of a building is heated to warm the flooring, and hot air is supplied into the room through a vent opening that communicates the room provided in the flooring and the underfloor space. An underfloor heating apparatus for heating, comprising a boiler that heats hot water, a radiator that heats the underfloor space with hot water, and a hot water pipe that connects the boiler and the radiator, and the radiator is around the vent What is hung and installed in the space under the floor is known. (For example, refer to Patent Document 2).

However, in the underfloor heating devices described in Patent Documents 1 and 2, when heat energy such as electricity or solar heat is stored in the soil as a heat source, heat is radiated from the vents (louver) provided on the floor to the living room. Therefore, heat cannot be stored efficiently. However, there is a problem that if the louver is eliminated, it takes time for the heat of the underfloor radiator to raise the floor surface when it is desired to warm the room actively and quickly, and it is difficult to warm.
In particular, heat radiation ends on a cold day, and there is a problem that even if the underfloor heating is operated after it gets cold, there is no immediate effect and it takes time to warm up.

    The present invention has been made to solve the above-described problems of the prior art, and provides a heating / cooling device capable of efficiently storing heat in a heat storage body under the floor of a building. A second problem is to provide a heating / cooling device and a heating device that can quickly warm the temperature of the room.

4. The heating apparatus according to claim 3, wherein the heat source is a heat pump type.

In the present invention, the radiator may be either a convection type or a radiation type, but a convection type radiator is more preferable in order to suppress uneven temperature on the floor surface and increase thermal efficiency.
The heat source of the radiator may be any of electricity including a combustion system such as gas or oil, or a solar battery using solar heat, but a heat pump type is more preferable.
As a convection type radiator, for example, high-temperature water produced by a separate hot water boiler or the like is supplied to a heat exchanger built in the radiator, while external air is supplied by a blower built in the radiator. Then, a hot water radiator that heats and blows off the external air can be mentioned by sending it to the heat exchanger and exchanging heat between the high-temperature water and the cold external air with the heat exchanger.

  In the present invention, the underfloor air is preferably forcedly convected. For example, in the above-described convection type radiator, underfloor air can be simultaneously taken in together with outside air, and the underfloor air can be forcedly convected by exchanging heat together. This makes the underfloor air more uniform and at the same time improves the thermal efficiency.

Since the through-hole which can be opened and closed is provided, the above-mentioned through-hole is closed when warm and cool air is stored in the soil concrete or the like which is a heat storage body under the floor. When the room is actively heated and cooled, the floor passage hole is opened so that warm air is supplied to the room. In this way, it is possible to efficiently control the heat storage in the soil concrete or the like and the heating and cooling of the living room. By doing so, all rooms can be comfortably heated and cooled while reducing running costs.

It is transmitted to the heat transfer plate and the living room becomes quick and comfortable. Moreover, since the heat conductivity of the plate-like heat transfer plate is good, the floor surface temperature can be uniformly warmed and the living room becomes more comfortable. In summer, the soil concrete surface is maintained at a temperature lower than the outside air temperature due to the influence of geothermal heat, so the floor surface temperature can be kept low by switching on the heat collecting plate, and comfort in the room Will improve.

  The heating device according to claim 3 is a heating device for a building having a floor on the soil surface via an underfloor space, and a radiator is provided in each of the interior of the floor and the underfloor space. Since it is connected to the heat source by a separate heat supply means and the heat supply from the common heat source to each radiator can be switched, the heat radiation is usually provided in the underfloor space using cheap midnight power for the heat source. Low-cost underfloor heating using only a heater, especially when cooling is severe and heat dissipation ends quickly, the radiator (floor heating) provided inside the floor is operated to quickly make the room comfortable be able to. In this case, it is economical to provide the in-floor radiator (floor heating) in a part of the area mainly composed of the living room.

The heating device according to claim 4 is highly efficient because the heat source of the heating device is a heat pump type, and generates the least amount of CO ₂ as compared with combustion systems such as gas and oil, and is environmentally friendly. In particular, CO ₂ refrigerant is a safe and thermally stable gas that is not toxic or flammable, collects the heat of air in natural refrigerant (CO ₂ ), and is 70% less expensive than the high efficiency heat pump type and daytime. The running cost can be significantly reduced by combining nighttime power.
