Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building capable of downward ventilation and upward ventilation, and a method of cooling and heating the building.

[0002]

2. Description of the Related Art At present, in many buildings in Japan, an indoor unit of an air conditioner is directly attached to a living space for cooling and heating the living space of the building.

However, in a building in which an indoor unit of an air conditioner is directly mounted on a living space in order to cool and heat the living space of the building, the temperature of the air in the living space varies greatly depending on the place, and the air flow in the living space varies. It is inevitable that strong currents will occur. Therefore, in a building where an indoor unit of an air conditioner is directly attached to a living space, humans cannot spend comfortably.

At present, in many buildings in Japan,
In order to cool and heat the living space of the building, create air that has been cooled and dehumidified or heated outside of the living space.
2. Description of the Related Art A method has been adopted in which cooling or dehumidified air or heated air is supplied to a living space and exhausted from the living space.

In this conventional method, a cooling air supply port for supplying cooling dehumidified air to a living space to cool the living space, and supplying heated air to the living space to heat the living space. A cooling air outlet for discharging air that has cooled the living space from the living space, and a cooling air outlet for discharging the air that has heated the living space from the living space. Exhaust port for heating is the same.

[0006] However, an air supply port that is appropriate for cooling is not appropriate for heating, and an air supply port that is appropriate for heating is not appropriate for cooling. For example, an air supply port provided in a ceiling of a living space is not suitable for heating even if it is appropriate for cooling.
Similarly, an outlet that is appropriate for cooling is not appropriate for heating, and an exhaust that is appropriate for heating is not appropriate for cooling. For example, an exhaust port provided in a lower wall of a living space is appropriate for cooling, but is not appropriate for heating.

[0007] Since the cooled air has a large specific gravity, it tends to move from top to bottom. Therefore, when cooling the living space, the living room is cooled by supplying the cooled air to the living space from the upper part of the living space, for example, from the ceiling, and exhausting the cooled air from the lower part of the living space, for example, the floor. The temperature distribution of the air in the space can be made relatively small, and the place where the air flow is strong can be made relatively small. Therefore, it is desirable that the building be a building that allows air to flow through the building from top to bottom during cooling, that is, a building that allows ventilation in the downward direction. Conversely, heated air tends to move from bottom to top because of its low specific gravity. Therefore, when heating the living space, the heated air is supplied to the living space from the lower part of the living space, for example, from the floor, and the air that has heated the living space is exhausted from the upper part of the living space, for example, from the ceiling. The temperature distribution of the air in the space can be made relatively small, and the place where the air flow is strong can be made relatively small. Therefore, it is desirable that the building be a building capable of circulating air from the bottom to the top during heating, that is, a building capable of upward ventilation. However, there is no known building capable of downward ventilation and capable of upward ventilation.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a relatively small air temperature distribution in a living space both for cooling and for heating, and for a place where the air flow is strong. It is an object of the present invention to provide a building capable of downward ventilation and upward ventilation, which can make the ventilation relatively low. Another object of the present invention is to provide a cooling and heating method for the building.
