Description

Detailed Description of the Invention [Industrial Application Field 1] The present invention is applicable to the use of OA equipment in winter or summer, or in factories, shops, sales areas, venues, research institutes, etc. When indoor air conditioning distribution is unstable due to significant temperature differences even in the same room due to indoor environmental conditions, it simultaneously supplies cooling and heating air distribution suitable for each temperature environment, making it ideal for indoor rooms. Air conditioning and heating systems that aim to provide a comfortable temperature at all times, very easily and reliably.
This relates to an air conditioner that performs both humidification and dehumidification.

[Prior Art] In an indoor room where a large number of people gather, such as an exhibition hall or a venue, the temperature difference may vary significantly depending on the condition of the group, the location near a window, the shade, etc. in each room.

Therefore, it is natural to expect a distribution of cooling and heating in rooms with different temperatures, but especially in recent intelligent buildings, office automation equipment and computer equipment are often used, and the amount of heat generated by these equipment is increasing. In some cases, the room needed to be cooled even in the winter, but on the other hand, the space where the interior design person was also had to be heated at the same time, creating a contradiction.

In addition, from the viewpoint of heating efficiency, it is natural that a mechanism that blows warm air from the bottom of the room, that is, from the floor, is the most ideal means of heating and is in high demand.

For this reason, air conditioners with different systems, such as a cooling system and a heating system, have traditionally been used, but when air conditioners with different systems are used, the duct arrangement becomes extremely complicated and multi-cone, which can lead to failures. Of course, there were concerns, but restrictions on the installation location inevitably led to the problem of high costs.

[Problems to be Solved by the Invention and Means for Solving the Problems]
In view of the above problems, two heat exchange systems, a cooling system and a heating system, are integrated in one device, and a damper for switching between cooling and heating ventilation paths can be opened and closed in each system. By setting up a damper and switching operations using each damper, a predetermined amount of cool air can be delivered to one part of the room, and warm air can be delivered to the other part of the room, depending on the situation and environment of the room, without having to install multiple heating and cooling equipment as in conventional mechanisms. The purpose of the present invention is to provide a cooling/heating brush air conditioner that can supply cooling and heating air simultaneously or separately, thereby constantly providing optimal air conditioning in a room.

[Function] The air conditioner for cooling and heating brushes according to the present invention is installed in a part of the room as shown in FIG. One of the outlets is connected through the ceiling duct (A) to the ceiling air outlet (B) opened on the ceiling, and the other outlet is connected to the underfloor duct (A).
The air vents (1) are opened above the floor through the air vents (1), and the air that can flow into the cooling chamber through these indoor vents is the cold air cooled by the cooling coils. In addition, the air that can be passed through the heat chamber is heated and humidified to an appropriate temperature using a heating coil, humidification mechanism, etc.
This warm air is blown into the room.

In addition, the switching operation of the blowing direction of the cold and hot air is performed by operating each damper to set a required state according to the indoor environment, and an example of the switching operation will be described below.

Summer season: Open dampers (a) and (b) (d) and (c) (
When f) is closed and (g) is opened, only cold air flows through the ceiling vent (
b) The air is cooled mainly from the upper part of the room.

Intermediate period: Close dampers (c) (f) and close all other dampers (a) (b) (g) and (d) (e) (h) (j
), cooling and heating operation is possible using all outside air, and in some cases,
By opening and closing the tambour (C), dehumidified air can be selectively blown out to the top and bottom, or only to the top, along with cool and warm air.

Winter season: Close dampers (a), (b), (c), and (f) (
When cf)Ce)(h) is opened, warm air flows toward F and heats the indoor floor surface.

Furthermore, by closing (b) and (h) and opening (f) and (g), only warm air flows upward and gradually heats the higher parts of the room.

Also, when (a), (b), and (c) are closed and all other dampers are opened, warm air flows upward and downward at the same time, rapidly heating the room.

Moreover, by opening and closing the damper (c) at the same time as described above, it is possible to simultaneously supply necessary humidification to the upper and lower parts of the room in addition to supplying warm air to the upper and lower parts of the room.

Note that, depending on the operation of each damper, it is also possible to supply humidified air to one side and dehumidified air to the other side.

In addition to the above, each damper can be operated in various ways depending on the indoor environment, orientation, changes in the temperature of cooling and heating, etc., and the temperature difference in the room can be changed and adjusted to the optimal state for the room each time.

Furthermore, it goes without saying that by installing the air conditioner body in an appropriate location such as in the floor, ceiling, or wall, it is possible to achieve more effective air conditioning control as well as design.
