BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for a room.

[0002]

2. Description of the Related Art Conventional cooling and heating devices are shown in FIGS.
In FIG. 3, the outdoor unit 1 is installed outdoors, the indoor unit 2 is installed indoors, the outdoor unit 1 and the indoor unit 2 are connected by a heat medium pipe 3, and the indoor air is a heat exchanger in the indoor unit 2. It is a separate type that can be cooled or warmed by. FIG. 4 is a so-called window type in which a refrigerator and a heat exchanger for heat radiation are housed in an integral casing 4. In FIG. 5, an outdoor unit 1 and a heat exchanger (air handling) 5 are connected via a heat medium pipe 3, and the heat exchanger 5 is installed indoors, for example, in the ceiling of a corridor. Is a duct type structure that cools or warms the air with, blows cold air or hot air from the air outlet 7 provided in each room via the duct 6, and sucks indoor air from the suction port 8 via the duct 9. This example is generally used for medium and large-scale cooling and heating in office buildings and the like.

[0003]

However, the above conventional example has the following drawbacks. a. In the separate type shown in FIG. 3, since the outdoor unit 1 and the indoor unit 2 are connected by the heat transfer medium pipe 3, it is necessary to have skill in the piping work of this heat transfer medium pipe 3, and the piping work is required in the urban area. Often difficult. There is a limit to the height between the outdoor unit 1 and the indoor unit 2. Further, the heat medium may leak from the connecting portion of the heat medium pipe 3 to contaminate the room or the wall surface, and in extreme cases, the building may be damaged. b. In the case of the window type shown in FIG. 4, there are no drawbacks as mentioned in the above a, but if it cannot be installed other than a window, or if it is in contact with the next house, it is limited to installation due to space or noise problems. May receive a. c. In the case of the duct type shown in FIG. 5, a large space is required in the ceiling for constructing the duct, the initial cost is high, and if the duct is exposed, it is not aesthetically pleasing, especially for individuals. Not suitable for housing.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and the constitution thereof is as follows. 1. A heating / cooling heat medium generator and a cold / warm air generator for cooling / warming the air with the heating / cooling heat medium generator are installed in the outdoor unit. Forming a mouth, the cold and warm air outlet and the indoor air suction port are connected to the cold and warm air generating device in the outdoor unit via a wall penetrating pipe consisting of a cold and warm air blowing passage and an indoor air suction passage, Air-conditioning system characterized by. 2. In the above-mentioned item 1, the cooling and heating device in which the wall penetrating pipe is a double pipe. 3. 1. The cooling and heating device as described in 1 above, wherein the wall penetrating pipe is partitioned by a partition plate into a cold / hot air blowing passage and an indoor air suction passage.

[0005]

In the outdoor unit, a heating / cooling heat medium generator and a cold / hot air generator are incorporated. On the other hand, since the indoor / outdoor unit is formed with a cool / hot air outlet and an indoor air intake port, the air sucked from the indoor unit's intake port passes through the indoor air intake passage of the wall-penetrating pipe into the cold / hot air generator. Then, it is cooled or warmed by the heat medium, reaches the room through the cold / hot air blowing passage, and is blown into the room from the cold / hot air outlet.

[0006]

EXAMPLE FIG. 1 shows an example of the present invention. Reference numeral 10 denotes an outdoor unit. Inside the casing 10a of the outdoor unit 10,
A heating / cooling heat medium generator A comprising an absorber 11, a condenser 12, a low temperature regenerator 13, and a high temperature regenerator 14, and an evaporator 15,
A cold / hot air generator B composed of a heat exchanger 16 for heating is also incorporated, and the heat medium pipe 25 between A and B is entirely provided in the casing 10a. Reference numeral 17 denotes an indoor unit. The indoor unit 17 has a cold air outlet 18 facing upward and a warm air outlet 19 facing downward, and an intake port 20 formed at a lower portion, which is a partition from the outdoor unit 10. Board 22
Thus, the cold / warm air blowing passage 23 and the indoor air suction passage 24 are directly connected to each other by the wall penetrating pipe 21 which is formed in two steps in the vertical direction.

In the case of cooling in this embodiment, the air sucked from the suction port 20 of the indoor unit 17 is
1 enters the cold / hot air generating device B via the lower indoor air suction passage 24, is cooled by the evaporator 15 into cold air, and cool air outlet of the indoor unit 17 via the cold / hot air blowing passage 23. Blow out into the room from 18.

In the case of heating, the indoor air sucked from the suction port 20 side of the indoor unit 17 enters the cold / hot air generator B from the indoor air suction passage 24, and here the heating heat exchanger 1
It is heated by 6 to become warm air, and is blown out into the room from the warm air blowout port 19 of the indoor unit 17 via the cold and warm air blowout passage 23.

The sectional structure of the wall penetration tube 21 is as follows.
Partitions as shown in FIGS. 2 (A) to (D), or (E)
It is possible to use a double tube structure as shown in (H) to (H) or a concentric double tube. In FIG. 2, S corresponds to the cold / hot air blowing passage 23, and R indicates the indoor air suction passage 2
It corresponds to 4.

[0010]

As described above, according to the present invention, the cold / hot air generator is incorporated in the outdoor unit side, only the cold / hot air outlet and the suction port are formed in the indoor unit side, and the wall penetration pipe is provided between the outdoor unit and the indoor unit. Tied in. As a result, the following effects are achieved. a. Since the blowout part of the indoor unit has a relatively simple structure, various measures can be taken. For example, as shown in FIG. 1, if the indoor unit is designed to blow upward in the case of cold air and downward in the case of warm air, it is possible to send the warm air to the feet of the living space during heating, which is not possible in the past. Comfort is obtained. b. Since the indoor unit only blows cold and warm air and sucks in indoor air, it can be downsized and designed in various ways. c. Since all heat medium piping is done in the outdoor unit,
There is no need to perform piping work when installing. d. Even if there is some leakage of piping, there will be no troubles such as loss of cooling and heating functions and stains on the walls, so no great skill is required for installation work. e. Since the cold air temperature during cooling can be made higher than the conventional refrigerant temperature and cold water temperature, the thickness of the dew condensation preventing heat insulating material can be made thin and the length thereof is short, so that the piping cost can be reduced. f. Since the cold / hot air generator is located outside (outdoor unit), drain piping from the room is not required. As a result, construction costs and workability are dramatically improved. g. Since the wall-penetrating pipe (cool / warm air duct) is short, the blowing capacity can be reduced, and the wall-penetrating diameter can be about 200 mm or less, so that it can be installed on walls other than windows. h. Since the wall penetration tube is in the concealed part, the aesthetically pleasing appearance can be eliminated.
