Description

[Detailed Description of the Invention] The present invention aims to unify the air supply ports of air conditioners and total heat exchangers in air conditioning systems installed in buildings, etc., and also facilitates complicated and diverse duct work. Concerning a significantly simplified air conditioning system.

Conventionally, the so-called air conditioning system that attempts to supply cooled and warmed air indoors has a floor-standing or ceiling-mounted air conditioner, a total heat exchanger, etc. placed in a predetermined place, and these are installed in each duct. The volume of air supplied to the room can be adjusted by operating dampers connected and installed in the middle of each duct, mixing outside air, cooling outside air using a bypass circuit, adjusting exhaust air to remove Co ₂ , and recovering amount of heat. Adjustments were being made.

However, since the directionality of the air inlets of the air conditioners and total heat exchangers generally used in the above mechanism is extremely inconsistent, the mounting positions of dampers and sensor mechanisms installed in each duct, etc. In some cases, the duct is installed over a very wide area, and at the same time as the duct is constructed, it is necessary to install various mechanisms such as a silencing chamber, a branching chamber, a supply chamber, etc. to prevent noise. As a result, the duct structure in the ceiling is diverse and complex, which not only causes problems in maintenance work, but also adds weight, making it impossible to carry out construction work, especially in a narrow ceiling. However, a portion of the room was exposed inside the room, which caused various problems in terms of the design and effectiveness of the room.

In view of the above-mentioned problems, the present invention is intended to fundamentally solve the drawbacks of the conventional air conditioning system. Openings for air blowing, suction, air supply/exhaust, return air, etc. are provided in the vicinity of the air outlet, and the interior of these air openings is partitioned with a number of partition plates to create a large number of air passages. An air conditioning system characterized in that the air conditioning system is configured such that the air supply and exhaust ports of a multi-purpose air chamber are formed and are each provided with a mechanism such as a damper and a sensor in the air passage. The aim is to provide a wide range of information.

Hereinafter, detailed description will be given with reference to drawings illustrating embodiments of the present invention. Reference numeral 1 denotes a multi-purpose air chamber with a return air port A, an outside air intake port B, and an exhaust port on the peripheral surface of the chamber as shown by dotted lines in the first drawing. Open port C, connection ports D and E with the exhaust mechanism, connection ports F, G, and H with the total heat exchanger, air supply port I into the room, and connection ports J and K with the air conditioner. At the same time, the interior is divided into several layers and several rooms with several partition plates, and a large number of air ducts (a), which will be described later, are installed.
Damper mechanisms a, b, c, d, e are provided on some of the partition plates.
The return air port A is installed so as to be openable and closed, and the return air port A is connected to the exhaust mechanism, the connection port D of the total heat exchanger, the connection port G of the total heat exchanger, and the connection port K of the air conditioner, and the outside air intake port B is connected to the total heat exchanger. Connect port F to the air conditioner connection port K, total heat exchanger connection port E to the exhaust port C, total heat exchanger connection port H to the air conditioner connection port, and connect the air conditioner connection port J to the indoor Each air passage A, B, which communicates with the air supply port I to
It is formed by C, E, O, F, Ki, and K.

Furthermore, sensors are installed at necessary locations in each of the air passage arches, and the respective damper mechanisms a to e are operated in response to sensor signals and signals from the control box 11 to adjust the amount of air being blown.

Depending on the purpose of use, it is also possible to add, reduce, or simplify the chamber structure of each chamber by increasing or decreasing the number of internal partition plates.

The total heat exchanger 2 has an exhaust bypass D', an exhaust port E', an outside air intake port F', a return air inlet G', and an air supply port H' opened in parallel in the upper part, and each of the above-mentioned ports D is provided inside. ′−
E', D'-G', G'-E', and F'-H' are connected through U-shaped air ducts L, M, and N, respectively.
Exhaust fan 4 and exhaust fan 5 are installed in M' and N.
Total heat exchange coils 6 are disposed in M and N, respectively. Air conditioner 3 has an outside air return port K′ and an air supply port at the top.
J' are opened in parallel, a U-shaped air passage P is formed inside the machine, and mechanisms such as a pre-filter 7, a heat exchange coil 8, an air blower fan 9, and a main filter 10 are arranged in the air passage P. It is what it is.

Incidentally, each opening of the total heat exchanger 2 and the air conditioner 3 may be provided on a side surface of the fuselage or a nearby side surface, depending on the case.

The present invention is composed of the multipurpose air chamber 1, total heat exchanger 2, and air conditioner 3 described above, and the total heat exchanger 2 and air conditioner 3 are installed at predetermined locations indoors and outdoors. Then, the return air port A of the multipurpose air chamber 1 is used as the indoor air intake port A', and the outside air intake port and exhaust ports B and C are used as the outdoor outside air intake port.
B' and exhaust port C', connection ports D and E with the exhaust mechanism to bypass port D' and exhaust port E' of total heat exchanger 4, and connection ports F and G with the total heat exchanger 4 to bypass port D' and exhaust port E' of total heat exchanger 4. Connect the connection port H with the total heat exchanger to the outside air intake and return air inlet G' of the heat exchanger 4, and connect the air supply port to the total heat exchanger 4.
H′ and the indoor air supply port I to the indoor air supply port.
At I', the connection ports J and K with the air conditioner are connected to the outside air return port K' and the air supply port J' of the air conditioner 5 by constructing ducts.

In addition, the total heat exchanger 2 and the air conditioner 3 include a floor-standing type,
A ceiling-mounted type or the like is used, and it goes without saying that the multipurpose air chamber 1 is formed to be compatible with this type.

As described above, the air conditioning system according to the present invention includes the total heat exchanger 2 and the air conditioner 3, each of which has air supply, exhaust, and return air inlets on the top or side surface and in the vicinity of the side surface. By connecting the ports of the multipurpose air chamber 1, which forms a large number of air supply chambers, the directions of each air supply, return air, etc. are completely unified, which greatly simplifies duct construction. Not only is the construction work easy and simple, no matter how narrow the ceiling is, but the damper motor, damper mechanism, and sensor device, which were conventionally attached to each mechanism separately, are now all in one place. It has the advantage that its operation and maintenance are extremely easy and reliable.

Furthermore, in the present invention, since the multipurpose air chamber 1 itself has a silencing effect, noise and vibrations entering the room can be significantly reduced and alleviated. It has great benefits as it can be used for various purposes such as return air exhaust chamber, bypass chamber, supply chamber, exhaust chamber, indoor air return branch chamber, air conditioner chamber, total heat exchanger chamber, etc. It also has effects.
