Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a heating and cooling device.

[Conventional technology]

Conventionally, an outlet is installed in the ceiling or upper part of a wall to blow cold air into the room during cooling and hot air into the room during heating, and the indoor air is exhausted during both cooling and heating. It has been common practice to provide the inlet at a suitable local location within the room, away from the outlet.

[Problem to be solved by the invention]

However, in the conventional general configuration as described above, there is a strong tendency for warm air to accumulate and accumulate in the upper part of the room during heating, which tends to cause problems such as cold feet even though the upper part of the room becomes excessively warm. Ta.

In addition, there is also the problem that air currents near the inlet are likely to cause discomfort, regardless of whether the air is being cooled or heated.Furthermore, stagnation of indoor air tends to form in some parts of the room, making it difficult to maintain uniform heating and cooling conditions. In addition, there are problems in that indoor ventilation tends to be insufficient in some parts of the room when it comes to maintaining a good indoor environment.

An object of the present invention is to effectively suppress each of the above-mentioned problems.

[Means to solve the problem]

The characteristic configuration of the heating and cooling device according to the present invention is that a plurality of vents are distributed and arranged in each of the ceiling and floor of a room to be heated and cooled, and the cold air is blown into the room from the vents in the ceiling, and the ventilation in the floor is A switch for switching the operating state between a cooling operating state in which indoor air is exhausted from the vent, and a heating operating state in which warm air is blown into the room from the vent in the floor and indoor air is exhausted from the vent in the ceiling. The purpose is to provide a means, and its functions and effects are as follows.

[For production]

In other words, looking at the vertical direction of the room, when cooling the room, by using a supply/exhaust mode that blows cold air into the room from the vents in the ceiling and exhausts indoor air from the vents in the floor,
The air supply/exhaust form is adapted to the falling phenomenon of cold air, and the indoor cooling state is made uniform in the vertical direction.

In addition, during heating, the air supply/exhaust mode is adapted to blow warm air into the room from the vents in the floor and exhaust indoor air from the vents in the ceiling, so that the air supply/exhaust mode corresponds to the rising phenomenon of warm air. As a result, the indoor heating state is made uniform in the vertical direction (that is, the accumulation and retention of warm air in the upper part of the room is effectively suppressed).

On the other hand, as mentioned above, by distributing the ceiling vents and the floor vents, which switch between the cold and hot air blowing state and the room air exhaust state, in the ceiling and the floor, it is possible to Irrespective of heating, the ventilation airflow flows in a laminar manner in the vertical direction at any point in the room, and the ventilation airflow state itself in the room is made uniform over the entire area of the room.

In other words, this uniformity of ventilation airflow prevents the airflow from becoming locally strong in some parts of the room, and effectively prevents discomfort caused by such localized airflow. It also prevents the formation of stagnation areas of indoor air in some parts of the room, and the formation of such stagnation areas causes uneven heating and cooling conditions and deterioration of the indoor environment. This can also be effectively prevented.

(Effects of the Invention) As a result of the above, both the cooling state and the heating state are uniform throughout the entire room, the airflow hardly causes discomfort, and the indoor environment is maintained well throughout the room. It has become possible to perform extremely superior heating and cooling.
