Description

[Detailed description of the invention] [Industrial application field] This invention relates to an air distribution device in an air conditioning system in which an outdoor unit and an indoor unit are separated. The present invention relates to an air conditioning system that can not only adjust the temperature and humidity of indoor air but also keep indoor air clean.

[Conventional technology]

Conventionally, a separate air conditioning system in particular has not been equipped with a device for taking in fresh air from outside. That is, the air cooled by the blower of the indoor unit is simply sent into the room through the refrigeration cycle, and the indoor air is simply stirred.

[Problem that the invention aims to solve] As described above, in the past, there was no special equipment for bringing in fresh air from outside, so it was necessary to install a ventilation fan in the room, or to install a door or I had to open and close the windows from time to time. However, since the ventilation fan only discharges indoor air and the amount of air discharged is too large,
It is also necessary to open and close the window. However, opening and closing the windows causes a large amount of indoor heating and cooling loss, and it is also a hassle to open and close the windows.

[Means for solving problems]

This idea was proposed as a solution to the above-mentioned problems, and involves opening the upper part of the wall where the cycle pipe connecting the outdoor unit and the indoor unit is attached, and opening the wall through this opening. An air conduction pipe is fitted, and one side of the air conduction pipe protrudes so as to be positioned above the blower of the indoor unit, and the other side protrudes outdoors, and the air conduction pipe The upper part is used as an intake pipe to take in fresh air from outside, and the lower part is used as an exhaust pipe to take in air from the inside of the indoor unit and exhaust stale indoor air. It is an object of the present invention to provide an air circulation device in a separate type air conditioning device characterized by the following.

[Effect]

This invention automatically takes in fresh air from outside. At this time, almost the same amount of stale indoor air as this intake of fresh air is automatically exhausted to the outside. Therefore, in a room equipped with a separate air conditioning system, air heating and cooling losses are extremely small, yet the air is purified and the temperature and humidity of the air are automatically adjusted appropriately. It turns out.

〔Example〕

An embodiment of this invention will be described below in detail with reference to the accompanying drawings. 1 is an outdoor unit, 1a is a compressor, 1b is a fan, and 1c is a condenser or cooler. 2 is an indoor unit, and 2a is a cooler or a condenser. 2b is a discharge port, and 2c is a blowing port. This outdoor unit 1 and indoor unit 2 are cycle pipe 3
are connected via. This cycle pipe 3
is installed by being inserted into a hole 4a drilled in the wall body 4. Reference numeral A denotes an air conduction pipe, and the middle part is separated, with the upper part serving as an intake pipe 5 and the lower part serving as an exhaust pipe 6. Furthermore, the air conduit A having such inlet and exhaust pipes is provided so as to protrude above the blower 7 inside the indoor unit 2.
This has an opening 4b in the wall 4, is fitted into this opening 4b, and is also projected outside the room. Furthermore, both ends of this air intake pipe 5 are open, so when air is drawn into the indoor unit 2, the blower 7 blows the air.
Since the air pressure near the outlet 2b on the front surface of the blower 7 is high, fresh air inevitably enters from the outdoor side of the intake pipe 5 and is sent into the room via the outlet 2b. Further, the exhaust pipe 6 has an opening 6a at least below the protruding part on the indoor unit 2 side and near the wall 4, and the stale indoor air is discharged from the air inlet 2c of the indoor unit 2 to the indoor unit. 2 and is discharged outside the room through the opening 6a.

Since this embodiment has the configuration described above, fresh air flows into the indoor unit 1 from outside through the intake pipe 5, as shown in FIG. This is because the air pressure near the discharge port 2b is increased by the action of the blower 7 of the indoor unit 2, so fresh air enters from outside, is cooled by the indoor unit 2, and then discharged into the room by the blower 7. It will be done. Therefore, the amount of indoor stale air that is approximately equal to the amount of fresh air flowing in from the outdoors is the amount of air that flows into the air inlet 2c of the indoor unit 2.
The air enters the indoor unit 2 and is discharged outside via the exhaust pipe 6. Moreover, these functions are completely automatic, and the indoor temperature and humidity can be adjusted, thereby purifying the indoor air.

[Effect of idea]

As will be described in detail in one embodiment, this invention can be used to automatically adjust the temperature and humidity of indoor air in a separate air conditioning system equipped with an outdoor unit and an indoor unit. Although the indoor air is constantly kept clean, there is extremely little temperature loss, and since it uses natural ventilation, there is no odor, so it is a device that has various practical effects.
