Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of controlling the air conditioning conditions simultaneously in a large number of rooms such as buildings, and in zones with completely different air conditions, such as interior zones, perimeter zones, etc. in each room. The present invention relates to an air flow distribution type air conditioner that allows for extremely simple and easy distribution of optimal air conditioning.

[Conventional technology]

Conventionally, as mentioned above, unit mechanisms such as supply air, return air, and exhaust air are installed in various parts of the room as a means of distributing cooling and heating air conditioning appropriately according to the indoor environment. Distributed arrangement has the drawback of high costs as well as installation and maintenance work.Moreover, when a mechanism such as a fan unit is installed indoors, the noise and vibration caused by the air supply noise may flow into the room. They had concerns.

As a means to solve these drawbacks, the development of air conditioners that integrate the above mechanisms is being considered, but most of them have a heat exchange coil above the blower that can be installed in the ventilation path due to the structure. Because of this arrangement, there are disadvantages in that the air flowing through the ventilation duct varies, making it impossible to obtain an ideal heat exchange effect. Dripping onto the blower was also a major cause of failure.

[Problem that the invention seeks to solve]

In view of the above-mentioned problems, the present invention corrects the unevenness of the air in the ventilation passage, makes the air flow constant at all times, and prevents water droplets from dripping on the blower and causing damage. Furthermore, the main purpose is to easily and reliably supply air at the required air volume and temperature to each of the zones by means of an air volume adjustment mechanism installed in each of the divided air channels. be.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an air intake, a perimeter, and an interior air outlet in the upper part of the fuselage, and a substantially U-shaped ventilation passage A that communicates the air intake and the air outlet. At the same time, mechanisms such as a pre-filter, a main filter, and a blower are arranged in the ventilation passage A, and a drain pan with a width larger than the diameter of the outlet is placed above the blower outlet in the front or rear direction. Erected biased to one side,
In an air conditioner in which a narrow ventilation passage is formed in front of the drain pan, the inside of the heat exchange chamber is divided into a plurality of chambers by a partition plate, and each chamber has a perimeter zone, an interior zone, etc., depending on the air conditions on the air supply side. It is an object of the present invention to provide an air flow distribution type air conditioner characterized by disposing cold and hot water coils of corresponding capacities.

[Effect]

The present invention has the above-mentioned configuration, and the air intake port 2 opened at the top of the fuselage is used as an outside air intake port, and each of the perimeter air supply port 3 and the interior air supply port 4 is connected through a duct (not shown). fresh outside air introduced into the ventilation passage A from the air intake port 2, or by the operation of the return air blower 8, The flow is dispersed in the heat exchange chambers C and C' on both sides formed at the top of the blower 8, and heat exchange is performed to an appropriate temperature in the respective cold and hot water coils 10 and 10', and the perimeter air supply port 3 and interior air supply are From the opening 4, it is possible to simultaneously supply and distribute optimal cold and warm air environments to the indoor perimeter zone and interior zone.

Meanwhile, the air volume adjustment mechanism 15 installed inside the aircraft,
By operating 15', the above-mentioned delivery form can be arbitrarily adjusted and changed, and one side can be closed to supply air only to the necessary locations.

〔Example〕

At the top of the fuselage 1, install air intakes 2 such as outside air intake and return air in appropriate locations, and on one side, install air intakes such as perimeter air intake 3 and interior air intake 4 in the required number for each zone. Each opening is provided, and the air intake port 2 and the perimeter, interior air supply port 3,
4 are communicated through a substantially U-shaped ventilation path A, and within the ventilation path A, a filter chamber a, a blower chamber b, and heat exchange chambers C and C' partitioned on both sides by partition plates 7 are formed, respectively. It will be set up.

Further, a main filter 5 and a pre-filter 6 are installed in the filter room a, and a blower mechanism such as a blower 8 and an electric motor 9 are installed in the blower room b.

Each of the heat exchange chambers C and C' is equipped with a heat exchange coil using cold water, hot water, or steam depending on the purpose, that is, cold and hot water coils 10 and 10 with the capacity adapted to each objective zone or with the same capacity. ′ are placed diagonally in the left and right chambers.

Further, below the cold and hot water coils 10, 10' and above the outlet 8' of the blower 8, there is a drain pan 11 whose bottom width is larger than the diameter of the outlet 8' and wider than the center of the body. 11' is the front in the wind passage,
Alternatively, the above-mentioned heat exchange chambers C, 11' may be installed biased toward either side of the rear side, and the above-mentioned heat exchange chambers C,
Narrow ventilation passages B and B' communicating with C' are formed.

The shape of the bottom surface of the drain pans 11 and 11' mentioned above is formed with arbitrary slopes such as front, rear, V-shape on both sides as shown in the second figure, but it can be formed horizontally or on both sides as shown in the front view of FIG. By arranging them in a gently sloping V-shape, the distribution of airflow is extremely smooth.

In the figure, reference numeral 12 indicates a coil mount and drain plate, 13 a humidifier, 14 a valve mechanism, 15 and 15' indicate necessary mechanical members such as an air volume adjustment mechanism, and the installation locations are limited to the illustrated examples only. It is not something that will be done.

In some cases, air supply ports 3 and 4 for each zone may be provided at the top, and air volume adjustment mechanisms 15 and 1 may be provided inside.
It goes without saying that a more effective sound damping effect can be expected by integrally connecting the sound damping/air volume adjusting chamber 16, which incorporates a mechanism such as a sound damping mechanism 5' and a sound damping mechanism, to the upper part of the fuselage 1. .

〔Effect of the invention〕

As described above, in the present invention, the drain pan 11 having a bottom surface with a larger diameter than the blower air outlet 8' is placed above the blower 8 in the heat exchange chambers C and C', and is biased toward either the front or the rear. Since the narrow passage B is formed in front of the drain pan 11, water droplets adhering to the coil surface do not fall onto the blower, and the drain pan 11 has a drip-proof function. The air flow is constricted and the wind speed is rectified to distribute the air flow almost evenly over the entire cold and hot water coil 10 at all times, making the heat exchange efficiency extremely good. In the shape of
Alternatively, by arranging them side by side in a gently inclined V-shape on the left and right sides, the airflow is naturally and very smoothly distributed into the left and right heat exchange chambers C and C', providing a more favorable heat exchange mechanism. be.

In particular, in the present invention, the plurality of heat exchange chambers C,
By arranging the cold and hot water coils 10 and 10' in C', respectively, the coils with capacities corresponding to their purposes can be used to control the air volume adjustment function for each room, perimeter zone, interior zone, etc. It is possible to simultaneously supply optimal air conditioning to indoor locations with completely different air conditions, and one air outlet can be closed to unnecessary locations, allowing air to be supplied only to the rooms where it is needed. It also has economic effects in terms of energy saving, such as energy saving.

Furthermore, in the present invention, the ventilation passage A is formed into a substantially U-shape, and the filter and the heat exchange coil are arranged diagonally, thereby achieving a noise reduction effect. This invention is optimal as an ultra-low noise type air conditioner by integrally providing a sound deadening/air volume adjustment chamber 16 on the upper air supply side of the machine body.
