Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner suitable for high-rise housing complexes.

Conventionally, as air conditioners for high-rise apartment buildings, air conditioners are installed in each house and operated and maintained individually.

Commercially available air conditioners for use in high-rise apartment buildings include window-type air conditioners that are installed by penetrating the wall and protruding indoors and outdoors, and those installed on balconies or outdoor walls. A split-type air conditioner in which the outdoor unit is installed indoors and connected to the indoor unit installed indoors through piping and wiring.The main unit is installed indoors next to a window, and the exhaust duct protrudes outdoors using part of the window frame. There are easily installed air conditioners that cool outdoor heat exchangers.

However, these are not necessarily suitable as air conditioners for high-rise apartment buildings.

In other words, the structure of a high-rise apartment complex is generally narrow in width and long in depth, with walls facing the outside air on one side facing the outside air and balconies facing the outside air on the other side. The surface is in contact with the neighboring house through a wall.

Generally, the house has two to four rooms that require air conditioning.

In this way, it is desirable that the interiors of high-rise apartment buildings have few walls that come in contact with the outside air, and that there are as few objects as possible on balconies and the like.

However, in order to air condition multiple rooms, multiple air conditioners are required.

To explain the disadvantages of installing each of the air conditioners currently on the market as described above, first of all, if you install a window type air conditioner, the external shape of the air conditioner body will be placed on the wall facing the outside air. Since it is necessary to drill and install a large through hole that is approximately the same as the size, the strength of the high-rise building is weakened, and the exterior unit protrudes from the outside, spoiling the aesthetic appearance.

Furthermore, the installation location is limited, and it is difficult to install it indoors where it does not face outside air.

Next, when installing a split type air conditioner, installation of the outdoor unit becomes a problem.

In other words, the outdoor unit must be installed outdoors,
In the case of this high-rise apartment building, the installation location is to be fixed to a balcony or an outdoor wall.

However, if it is installed on a balcony, the effective area of the balcony will be impaired, and if it is fixed to an outdoor wall, maintenance and management will be difficult, and furthermore, the appearance will be unsightly.

Next, when installing a simple installation type, air conditioning can only be achieved in rooms with windows facing the outside, and the installation location is also limited to the window side.

The present invention was invented in order to eliminate the drawbacks of each of the air conditioners described above, and its purpose is to centrally install outdoor units in one place indoors and to penetrate the wall surface to allow outside air to flow through. In addition to exchanging heat between the outdoor unit and the outside air through the through duct that introduces and exhausts air, the indoor unit can be installed at any location in each room to perform indoor air conditioning by using connecting piping. The present invention provides an air conditioner that can perform the following functions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be explained below based on embodiments thereof with reference to the drawings.
