Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically adjusts the imbalance of cold and warm air in the room in a factory, a meeting place, a hotel, an office, etc., so that it can be naturally adjusted to the indoor environment. The present invention relates to a multi-purpose terminal type air conditioner that is optimum as an energy-saving measurer by effectively utilizing the amount of heat that can be obtained and returned from the room.

[0002]

2. Description of the Related Art Conventionally, several air conditioners have been installed and used at respective required places as means for heating and cooling a wide area or a large number of rooms.
A so-called terminal type air conditioner is being developed, which is configured so that a single device can perform different operations such as return and exhaust.

[0003]

However, most of the above-mentioned models that can be developed have the same air volume at all times, so even if they are in the same room, depending on the relationship between windows, room corners, population density, etc. If the temperature in the room is remarkably different from the inside and outside, it is difficult to maintain a substantially uniform cooling and heating environment in the room, especially without considering the amount of heat in the air returned from the room, and in a random manner together with the contaminated air. It was released outdoors and was very uneconomical.

[0009]

As described above, according to the present invention, the flow of each air such as the outside air, the return air, and the exhaust air flowing through the air passage A for the perimeter zone, the air passage B for the interior zone, and the air passage C for the central zone is controlled in each passage. In this case, the air flow changing and adjusting dampers (1) to (10) are operated to change the mutually compatible distribution and the air volume and the air speed, so that the air can be sent. Even in the same room such as a zone, it is an optimal invention as a multipurpose air conditioner that can simultaneously send cold and warm air with different cooling and warming temperature airflows so as to immediately adapt to the indoor environment. .

Particularly, in the present invention, as described above, the heat quantity in the air collected from the interior zone can be mixed with the air for the perimeter zone again without being discarded, so that the heat quantity used can be greatly reduced. Of course, even during the off-season, appropriate humidification is sent to the room along with the air blow, so that a healthy environment can be easily obtained at all times without drying the room. ing. Furthermore, structurally, a plurality of ventilation passages are integrally formed, so only one total heat exchanger is required, and a large number of pipes are also housed in one place, making the entire machine extremely compact and simple. It also has the advantage that various operations are easy.

Furthermore, by constructing a silencing chamber in the upper part of the machine body as claimed in claim 3, a very quiet air-conditioning development can be obtained at the same time, so that a low noise and economical terminal type air conditioner can be obtained. Let's say so.
