Description

[Detailed description of the invention] This invention is a so-called system terminal type air conditioner that attempts to perform all heat exchange operations such as supply air, return air, and exhaust air fully automatically and efficiently in one device. The present invention relates to a terminal type air conditioner which has a very low overall height and is quiet and has excellent heat exchange efficiency.

Recently, with the rapid progress of the construction industry, it is natural that ideal air conditioning management inside buildings is required. At the same time, these air conditioners are now using terminal type air conditioners, which integrate mechanisms for supply air, return air, exhaust air, etc., which have traditionally been distributed separately due to installation space. Development was desired.

In view of the demands of the industry, the inventor first formed a U-shaped external air supply passage A that communicates from the outside air intake port 2 to the air supply port 5 in the fuselage 1 as shown in FIG. A filter in the external air supply passage A;
Various mechanisms such as a cold/hot water coil, a blower, etc. are provided inside the external air supply passage A, and a U-shaped internal air supply passage B communicating from the return air port 4 to the exhaust port 3 is formed above and below, and the above-mentioned internal and external air supply is provided. A total heat exchanger 6 is arranged between the air passages A and B, and several damper mechanisms are arranged between the inner and outer air passages A and B to circulate a part of the air to the inner and outer passages A and B. We have developed a fully automatic terminal type air conditioner, but we have developed multiple rows of air supply passages A and B within the machine casing, which is limited as described above.
Forming them in parallel vertically increases the bulk, which sometimes limits the installation location.

The present invention is an attempt to fundamentally solve the above-mentioned drawbacks, and the internal structure of the air conditioner has been drastically revised to make the overall shape extremely compact, resulting in a more efficient air conditioner. Its main purpose is to provide a terminal type air conditioner.

The structure of a specific example will be explained below with reference to the drawings.The inside of the fuselage 1 is divided into front, rear, left and right sides by several partition plates 11... Each ventilation chamber 15 etc. is formed and provided, and the respective ventilation chambers are communicated through air supply passages A, B, C, D, E, F, and an outside air intake port 2 is connected to the outside air introduction chamber 12.
An exhaust port 3 is provided in the exhaust chamber 13, a return air port 4 is provided in the return air chamber 14, and an air inlet port 5 is provided in the air supply chamber 15 at the top, respectively, and total heat is exchanged between the outside air introduction chamber 12 and the exhaust chamber 13. A return air blower 7 is arranged in the return air chamber 14, an air blower 8 is arranged in the air supply chamber 15, and various mechanisms such as a heating/cooling coil 9 and a heating coil 10 are arranged. Furthermore, dampers a, b, and c are provided at necessary locations in each of the air supply passages A, B, C, D, and E to reduce the air flow flowing through each of the air supply passages A, B, C, D, and E. It is characterized by being able to switch and adjust a part of it in any direction.

In addition, in the drawing, symbols 7a and 8a are the electric motors of the blowers 7 and 8, and 2a, 3a, 4a, and 5a are the exhaust ports 5.
etc., showing the filter mechanism installed inside the mouth of each.

In some cases, it is also possible to connect a sound-deadening chamber box having the filter mechanism incorporated therein so as to be freely connectable to the upper part of the main body of the fuselage 1.

16 is a humidifier, 17 is an inspection door, and 18 is a drain pan.

The present invention has the above-mentioned structure, and fresh air flowing in from the outside air intake port 2 is sent into the room from the air supply port 3 through the air supply passages A, B, and D as shown by the arrows. During that time, part of the ventilation is carried out by damper a,
Due to the action of b, heat exchange is performed in the total heat exchanger 6 and the heating/cooling coil 9 to an appropriate temperature. Also, at the same time as the above operation, air inside the room is introduced into the return air chamber 14 through the return air port 4, and a part of the air is exhausted to the outside through the exhaust port 3 as contaminated air. As a result, part of the room air is mixed with the total heat exchanger 6 or the fresh air, and then flows out into the room again through the air supply port 5, making extremely effective use of the thermal energy that was conventionally exhausted. It is possible to do this.

As described above, the terminal type air conditioner according to the present invention divides the inside of the fuselage 1 into front and rear parts by the partition plate 11, and has an outside air introduction chamber 12, an exhaust chamber 13, a return air chamber 14, and an air supply chamber 1.
Since the ventilation chambers No. 5 are formed adjacent to each other, the air supply passages do not overlap vertically as described above, and can be formed with a very low volume. Not only can the necessary equipment installed in each ventilation room be arranged stably, but the overall shape is compact and can be easily installed in any location. It has several advantages.
