Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is applicable to winter, summer, or indoors such as factories, shops, sales floors, venues, research institutes, etc. Depending on the large-scale environmental conditions such as the heat generated by equipment, there may be a significant difference in temperature within the same room, and the distribution of heating and cooling within the room may be unstable. The present invention relates to an air conditioner for cooling/heating, humidification, and dehumidification, which very easily and reliably supplies and distributes hot and cold air suitable for the indoor environment, simultaneously or separately, and adjusts the air volume.

[Prior Art] Conventionally, 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 crowd density, the location near a window, the shade, and other environmental conditions in the 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, it may be necessary to cool the room even in winter, but on the other hand, there is a contradiction in that areas where people are present, such as interior areas, must be heated at the same time.

In addition, from the viewpoint of heating efficiency, etc., the most ideal means of heating is a mechanism that blows warm air from the floor and cold air from the ceiling, but at present, the air conditioning system and heating system Several different air conditioners were used.

However, when installing air conditioners with different systems, the duct arrangement becomes extremely complex and there is a risk of failure, and the installation location is restricted, making it expensive. be.

For this reason, the inventor first formed a blow chamber, a cooling chamber, and a heating chamber into one unit, and installed a blow passage switch and a shunt wind damper between each chamber to freely switch and adjust the cooling and heating air in the room. He developed a so-called air conditioner that can be used for cooling/heating, heating, and dehumidification, which can easily obtain the optimal temperature distribution by sending air to the indoor ceiling, floor, or other directions depending on the environment, and has achieved considerable results. .

[Problem to be solved by the invention] However, as mentioned above, in the prior invention, each chamber such as a blowing chamber, a cooling chamber, a heating chamber, etc. is formed in an integrated structure, so the overall shape is a little strange. There is a concern that the size will be large, and because the airflow branching is not smooth, there will be some resistance in the ventilation path.Furthermore, the accuracy of adjusting the airflow for the difference in air volume between cold and hot air is insufficient with only damper operation, so fine adjustment is required. It was extremely difficult.

The main purpose of the present invention is to fundamentally solve the above-mentioned drawbacks, to enable fine adjustment operations, and to expect a more complete and reliable heating and cooling supply effect.

[Means for Solving the Problems] In view of the above-mentioned problems, the present invention integrates two heat exchange systems, a cooling system and a heating system, in one device,
Each of the above-mentioned systems is equipped with ventilation passage switching and branch dampers that can be opened and closed, and by switching operations using each damper, it is possible to adjust the temperature within the room according to the situation and environment of the room, without having to install multiple air-conditioning devices as in conventional mechanisms. In a heating/cooling air conditioner configured to send cold air of a predetermined amount of heat to one side and cold air of completely different temperatures such as warm air to the other side simultaneously or in different directions, Open the air outlet of the blower in the chamber toward the cooling chamber ITJ l, In order to open the air vents of the cooling chamber and the heating chamber toward the air outlet of the above-mentioned blower, both openings are tilted at an approximately square angle. The purpose of the present invention is to provide an air conditioner for cooling/heating, humidification, and dehumidification in which air volume adjustment dampers are installed in each of the inclined air vents so that the air volume can be adjusted freely.

U Effect 1 The air conditioner for cooling and heating inner lids according to the present invention is installed indoors or outdoors, connects the outside air suction port and the return air port of the ventilation chamber to the respective air receiving parts, and connects the ventilation port of the branch chamber to the duct. It is used by connecting each to the indoor air outlet through.

For example, cold air from a cooling chamber is sent to the body of the room through a ceiling outlet installed on the ceiling, and hot air from a power heating chamber is sent to the floor via an underfloor duct. Heating is provided to the F side of the room from the floor vents that open on the floor.

In addition, changes and adjustments to these heating and cooling supply means can be made by switching the air passages installed in the air passages between the valley chambers, dividing the flow,
By adjusting the opening and closing of the air volume adjustment damper, it is possible to supply the catfish with the required amount of cooling and heating air in each direction described below.

An example of the operation will be explained below.

Symbols・(aXc)(d)(D・Blow passage switching, diversion damper(b)(e)(g)(h) Indicates door passageway opening/closing damper.

To cool the body of the room E... When you open dampers (a) and (b), close dampers (d), (c), and (f), and open dampers (g), cold air is blown out from the ceiling vent and is mainly directed to the upper floors of the room. Cool the area.

B When cooling the upper part of the room and heating the floor... Close dampers (c) and (f), and close all other dampers (a) and (b).
When (g), (d), (e), (h) and (j) are opened, the air from the blower is divided into cooling and heating chambers, supplying cold air to the upper part of the room and warm air to the vicinity of the floor.

In some cases, the damper (c) may be opened and closed to blow humidified and dehumidified air into the room at the same time as the above-mentioned upper and lower cold/warm air is supplied.

When heating near the indoor floor... Close dampers (a), (b), (c), and (f) (d) and (e).
When (h) is opened, warm air flows downward and heats the indoor floor.

When supplying the necessary cooling or heating to the L layer or lower layer of the room... By closing dampers (b) and (h) and opening (f) and (g), only warm air flows in the direction. to gradually heat 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, heating the room in the second gear.

Furthermore, 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.

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

In other words, cool air is sent to the interior, cold air is sent to the bottom, and warm air is sent to the top.
Warm air to the lower part, cold air to the upper part, dehumidified air to the lower part, ■] Also, by fully opening the damper (J) of the outside air intake... Cold air is supplied to the upper part, outside air is supplied to the lower part, and the required 7JD humidity and dehumidified air are easily obtained each time by liquefying the indoor cool and warm environment by adjusting the tamper operation.

In particular, when the difference in the cold and hot air flow M is different during cooling and heating, it is possible to finely adjust the air flow rate by operating the air adjustment mechanism 41.

"Effects" As described above, the air conditioning/humidifying/dehumidifying air conditioner according to the present invention has the cooling and heating chambers adjacent to each other, and the ventilation openings and intermediate parts of both chambers, and the outlet part of the branch chamber. Several dampers (a), (b), (c), (dXe), (fXg), (h), etc. for switching the cooling and heating air passages are installed in each of the air passages, so that each cooling and heating air passage can be switched freely. By opening and closing operations, the cold and warm air heat exchanged in the cooling and heating meat chamber is cooled and warmed at the same time depending on the indoor temperature and environment.
Or it has the function of feeding differently.

Therefore, there is no need for air conditioners with different heating and cooling systems for cooling and heating as in the past, and a single air conditioner can simultaneously supply cool and warm air at different temperatures to the same room or multiple rooms.
For example, it is possible to easily supply cold air near the indoor ceiling and warm air near the floor, but it also has the effect of constantly maintaining an ideal indoor environment by being able to blow air in different directions. .

In particular, in the present invention, the air outlet of the air blower is opened toward one cooling chamber, and the air inlets of the cooling chamber and the heating chamber are opened in an inclined manner at an approximately doglegged angle. Air can be naturally flown into the cooling and heating chamber through the vents with almost no resistance, and it also has a noise-muffling effect.

Furthermore, by arranging the heating coil and the cooling coil according to claim 1 at a constant angle of inclination in the cooling chamber and the ventilation chamber, the overall shape can be greatly improved by forming each of the inclinations of the blower outlet and the ventilation hole. It has advantages such as being able to be made compact and compact.

In addition, by movably disposing the airflow adjustment mechanism in the front position of the air outlet in the air branching chamber according to claim (2), the amount of air blown to the cooling and heating chambers can be easily switched and adjusted. This method is significant in that it allows for easy fine adjustment of the amount of cooled or heated air, which was said to be inaccurate and unstable when operated only.
