Description

Indoor air conditioning system

Technical Field

The present invention relates to an air conditioning system using a blower used for indoor air conditioning.

Background

Conventionally, it is known that such an air conditioner gives a user a feeling of contact with natural wind by performing control of applying a combination of changes in a plurality of waveform patterns to the blowing wind speed of an indoor unit of an air conditioner (for example, see patent literature 1).

The air conditioner will be described below with reference to fig. 4.

As shown in fig. 4, a conventional air conditioner 100 includes a fan (not shown) and a heat exchanger (not shown) inside a main body 101 of a horizontally long indoor unit. Main body 101 has suction port 102 on the top surface and discharge port 103 at the bottom of the front surface. The air in the room is taken in through the air inlet 102, cooled or heated by an internal heat exchanger, and then blown out through the air outlet 103, thereby conditioning the air in the room.

Two

vertical vanes

104a and 104b are provided in the outlet 103 in the lateral direction, and the angle of the air blown out vertically from the air conditioner 100 is changed on the right side and the left side, respectively, when viewed toward the air conditioner 100. Further, at the air outlet 103, similarly, right and left

wind direction plates

105a, 105b are provided on the right and left sides, respectively, as viewed toward the air conditioner 100, so as to change the angle of the wind blown out to the right and left from the air conditioner 100.

Then, a plurality of waveform patterns including a waveform pattern Pa of a sine wave and a waveform pattern Pb having a period smaller than 1/4 of the waveform pattern Pa and having an amplitude equal to or larger than the waveform pattern Pa are synthesized, and the wind speed of the wind blown out from the air outlet 103 is controlled so as to vary with time.

Disclosure of Invention

In the conventional air conditioner 100, air cooled or heated by the heat exchanger is blown at an air speed corresponding to a heat load in the room to adjust the temperature of the room. Therefore, when the blown wind directly contacts the occupant, the occupant may be uncomfortable even if the wind speed changes to give a feeling of contact with the natural wind. That is, in summer, the user feels discomfort due to contact with supercooled wind; or, in winter, even warm air may feel cold due to contact with wind. Since the supplied heat, that is, the outlet temperature and the outlet air speed are changed in accordance with the heat load in the room, the air in contact with the occupant does not necessarily have to be comfortable for the occupant.

The invention aims to provide an indoor air conditioning system which can make the air blown out like natural air even though the air is artificial air.

In order to achieve the object, an indoor air conditioning system according to an aspect of the present invention includes: a first suction port that sucks air in a living space including a windowed wall provided with a window, an opposed wall opposed to the windowed wall, and a ceiling; a circulation air conditioner for adjusting the temperature of the air sucked from the first suction port; a first blowout port that supplies air temperature-adjusted by the circulation air conditioner to the living space; a blower that generates a flow of air; and a second air outlet that supplies air blown out by the air blower to the living space. The second air outlet has a slit shape, is provided on the side of the window wall of the ceiling so that the long side of the slit shape is parallel to the window wall, and blows out air in a direction away from the window wall. Thereby, the desired object can be achieved.

According to the indoor air conditioning system of the aspect of the present invention, since the wind is circulated throughout the living space as if the wind is blown from the window, the occupant can feel the wind blown out from the indoor air conditioning system as if the wind is natural wind.

Detailed Description

Hereinafter, embodiments will be described with reference to the drawings for understanding the present invention. The following embodiments are merely examples embodying the present invention, and do not limit the technical scope of the present invention. In all the drawings, the same portions are denoted by the same reference numerals, and redundant description thereof is omitted.

(embodiment mode 1)

Fig. 1 is an indoor conceptual view of a living space 1 including an indoor air conditioning system according to the present embodiment, and is a view when a window 3 is viewed from the inside. In addition, fig. 2 is a schematic view of an indoor air conditioning system.

As shown in fig. 1 and 2, the indoor air conditioning system is installed in a living space 1 which is an indoor space such as a house. The living space 1 includes: a window wall 20 having the window 3, an opposing wall 21 opposing the window wall 20, two side walls 22 (side wall 22R, side wall 22L) adjacent to the window wall 20 and the opposing wall 21, a ceiling 23 contacting the side walls 22, the window wall 20, and the opposing wall 21 at the upper vertical side, and a floor 24 contacting the side walls 22, the window wall 20, and the opposing wall 21 at the lower vertical side.

The indoor air conditioning system includes a second suction port 8, a second blowout port 4, a blower 6, a first suction port 7, a first blowout port 2, and a circulating air conditioner 5.

The second suction port 8 is provided in the ceiling 23 at a position closer to the opposing wall 21 than the second discharge port 4. The second suction port 8 is provided near the opposite wall 21 of the ceiling 23. The second suction port 8 is provided as an opening through which air of the living space 2 is sucked. Here, the vicinity means a distance within 1 m.

The second air outlet 4 is a rectangular opening, and has a slit shape, for example. The second air outlet 4 is disposed in the vicinity of the windowed wall side of the ceiling 23 so that the long side of the slit shape is parallel to the windowed wall 20. Here, the parallelism need not be strictly parallel, and is included as long as the long sides are disposed along the windowed wall 20. The vicinity is a distance of 1m or less. The long side of the slit shape of the second suction port 8 has the same or larger width as the window 3. Here, the width of the window 3 is not the width of the opening, but is the width of a frame provided around the window to fix the window. The direction in which the second air outlet 4 blows out air is a direction away from the window wall 20, that is, a direction of the opposite wall 21.

As shown in fig. 2, the blower 6 guides air from the second suction port 8 to the second blowout port 4. In other words, the blower 6 generates a flow of air from the second suction port 8 to the second blowout port 4. That is, the blower 6 sucks air in the living space 1 through the second suction port 8 and supplies the air into the living space 1 through the second blowout port 4. In other words, the second outlet 4 supplies the air blown out by the blower 6 to the living space 1. That is, the air supplied by the blower 6 circulates in the living space 1.

The blower 6 changes the wind speed of the air blown out from the second air outlet 4. The blower 6 is preferably operated so that the wind speed fluctuates like natural wind. Specifically, for example, speed control based on the 1/f fluctuation theory as disclosed in patent document 2 (japanese patent application laid-open No. 2-218892) or the like may be used. In addition, the installation position of the blower 6 is not particularly determined. In fig. 2, the blower 6 is provided outside the living space 1, but may be provided inside the living space 1, for example.

The first suction port 7 is provided as an opening that sucks air of the residential space 1. The first suction port 7 is provided in the opposed wall 21 at a position lower than the center of the distance from the floor surface 24 to the ceiling 23 in the height direction.

The first outlet 2 blows out cold air, hot air, or the like whose temperature has been adjusted by the circulation air conditioner (the circulation air conditioner 5 in fig. 2). The first blowout port 2 is provided at the peripheral edge of the ceiling 23 of the living space 1. Specifically, the first outlet 2 is provided at a position farther from the second outlet 4 (position closer to the opposing wall 21) with respect to the window wall in the peripheral edge portion of the ceiling 23. By providing the first blowout port 2 in the peripheral edge portion, it is difficult for the air blown out from the first blowout port 2 to directly contact the occupant. Here, the peripheral edge portion is a region within a distance of 1m from the end edge of the ceiling 23.

After the air sucked through the first suction port 7 is heated and cooled, that is, temperature-adjusted by the circulation air conditioner 5, the temperature-adjusted air is blown out from the first outlet 2.

The above is the structure of the indoor air conditioning system. In the above configuration, the circulation air conditioner 5 sucks air in the living space 1 through the first suction port 7, cools or heats the air, and then supplies the air to the room through the first discharge port 2. Although not shown, the circulation air conditioner 5 performs temperature control of the living space 1 based on the indoor temperature detected by the temperature sensor provided in the living space 1 and the set temperature set by the occupant.

According to this structure, the air flow that feels like natural wind flows from the window 3 side by the blower 6 while the room temperature in the living space 1 is kept at a comfortable room temperature by the circulation air conditioner 5. I.e. as if the window 3 were opened and a pleasant wind would enter.

As shown in fig. 2, the air blown out from the second air outlet 4 is divided into the second air inlet 8 provided in the ceiling 23 near the opposite wall 21 and the first air inlet 7 provided below the opposite wall 21, and is sucked in. That is, the air blown out from the second blowout port 4 is sucked in from the first suction port 7 and the second suction port 8. Therefore, the wind flows from the windowed wall 20 of the living space 1 toward the opposite wall 21, that is, the whole area of the living space 1. Thus, even if the wind speed of the wind blown out from the second air outlet 4 is reduced, the wind can be made to flow to the corners in the living space 1. This makes it possible to blow air from the second air outlet 4 without directly bringing strong wind into contact with occupants in the living space 1, and to realize comfortable natural wind.

The air blown out from the second air outlet 4 is sucked through the second air inlet 8 provided in the ceiling 23 and the first air inlet 7 provided below. The first outlet 2 of the circulation air-conditioner 5 is located between the second outlet 4 and the second suction port 8, and between the second outlet 4 and the first suction port 7. That is, the air temperature-adjusted by the circulation air conditioner 5 is agitated in the vertical direction by the air that is not temperature-adjusted from the second air outlet 4, and circulates in the living space 1. Therefore, the air whose temperature is adjusted by the circulation air conditioner 5 flows throughout the living space 1, and the temperature adjusting function in the living space 1 is improved. Further, the temperature difference caused by the position in the living space 1 can be reduced, and the discomfort given to the occupant in the living space 1 due to the temperature difference can be suppressed.

Note that, in winter, the user sometimes feels cold when directly contacting with wind. In addition, discomfort may be felt in summer due to direct contact with cold wind. However, according to the indoor air conditioning system of the present embodiment, when the temperature of the living space 1 is adjusted to the set temperature by the circulation air conditioner 5, the air directly heated and cooled by the circulation air conditioner 5 is blown downward from the first blowing port provided in the peripheral edge portion of the ceiling 23, and does not directly contact occupants located near the center of the living space 1. The air mixed in the living space 1 and adjusted to an appropriate temperature is blown out from the second outlet port 4 by the blower 6, and a flow of air from the windowed wall 20 toward the opposing wall 21 is formed in the living space 1. Therefore, the indoor air conditioning system can comfortably receive natural wind in both winter and summer.

Further, the width of the second air outlet 4 in the longitudinal direction is set to be substantially the same length as the lateral width of the window 3, so that the air blown out from the second air outlet 4 feels as if it were blown in from the window 3.

The air blown out from the second air outlet 4 is blown out so as to spread from the vicinity of the floor to the position of the head of the occupant in the vicinity of the center portion of the living space 1 while being separated from the window 3, as shown in fig. 1. That is, the air blown out from the second air outlet 4 is blown out from the window 3 toward the living space. In this case, the position of the head of the occupant differs depending on the situation, and for example, the head in a sitting state or the head in a standing state can be set in accordance with a command to the control unit described later. Here, the general living area is a range from the floor 24 to a height of 1.8 m. In ISO, the height of 1.7m may be set as the position of the head in the standing position, and the height of the air blown out from the second air outlet 4 toward the standing position of the occupant may be 1.7 m.

The installation position of the circulation air conditioner 5 is not determined. In fig. 2, the circulation air conditioner 5 is installed outside the living space 1, but may be installed inside the living space 1.

Although not shown, the second air outlet 4 has an airflow direction adjustment plate arranged in parallel from the window 3 side to the interior side of the living space 1. The wind direction adjustment plate is, for example, a blade. The angle of the airflow blown into the living space 1 is adjusted by adjusting the angle of the airflow direction adjustment plate (not shown). When the occupant sits, the air flow is blown out toward a slightly lower position (shown as air flow W1 in fig. 1 and 2), and when the occupant stands, the angle is adjusted so that the air flow reaches a higher position (shown as air flow W2 in fig. 1 and 2). The control device for controlling the blower 6 adjusts the angle of the airflow direction adjustment plate by a stepping motor (not shown) provided inside the second outlet 4. The instruction for the angle adjustment of the airflow direction adjustment plate may be performed by the occupant through a remote control device (not shown). Further, the position and posture of the occupant may be recognized by an output of a human body detection sensor (not shown) provided in the living space 1, and the angle adjustment of the wind direction adjustment plate may be instructed based on the position information.

As described above, the second air outlet 4 is provided with the airflow direction adjustment plate in parallel with the longitudinal direction. The angle of the wind direction adjustment plate is adjusted so that the wind can reach a range of 1.7m upward from the floor surface of the living space 1.

(embodiment mode 2)

A second embodiment of the present invention will be described with reference to fig. 1 and 3.

The indoor air conditioning system of the present embodiment includes a third suction port 25, an outside air introducing device 10, and a damper 14, in addition to the configuration of embodiment 1.

The third suction port 25 is provided on the outer wall surface of the house, and is an opening for introducing outside air, that is, outside air, outside the house into the living space 1.

In the outdoor air introducing unit 10, the outdoor air introducing part of the outdoor air introducing unit 10 is connected to the third suction port 25, and the air blowing part (the side connected to the first outlet 2 and the second outlet 4 of the living space 1) of the outdoor air introducing unit 10 is connected to the damper 14. In other words, the outside air introduction machine 10 is located on the upstream side of the damper 14. The outdoor air introducing device 10 includes a dust filter 11, a humidifier 12, and a heat exchanger 13.

The dust filter 11 can remove dust contained in the outside air by allowing the outside air sucked through the third suction port 25 to pass therethrough. Then, the second air outlet 4 blows out clean air from which dust is removed from the outside air by the dust filter 11. That is, the outside air introducing device 10 can function as an air cleaner.

The humidifier 12 can humidify the outside air from which the dust is sucked and removed through the third suction port 25. That is, the outside air introducing device 10 can function as a humidifier.

The heat exchanger 13 exchanges heat between the air sucked through the third suction port 25 and the air sucked through the second suction port 8 of the living space 1. That is, the outside air introducing unit 10 can function as a heat exchanger.

The damper 14 switches or mixes the outside air blown out from the outside air introducing device 10 and the return air sucked from the second suction port 8 of the living space 1. That is, by controlling the position of the damper 14, the air blown out from the blower 6 can be switched to either all the outside air, the mixture of the outside air and the return air, or all the return air (i.e., circulation). In other words, the damper 14 adjusts the ratio of the air from the second suction port 8 to the outside air sucked from the third suction port 25. Then, the second blowout port 4 supplies at least one of the air from the second suction port 8 and the outside air from the third suction port 25 adjusted by the damper 14 to the living space 1.

The blower 6 of the indoor air conditioning system of the present embodiment sucks outside air and supplies the sucked outside air into the living space 1. The sucked outside air is treated by the outside air introducing machine 10 before being supplied into the living space 1. The outdoor air introducing unit 10 purifies the outdoor air by the dust filter 11, humidifies the outdoor air by the humidifier 12, and cools or heats the outdoor air by the heat exchanger 13. The air blown out from the second outlet 4 approaches the temperature in the living space 1 by heat exchange. Therefore, when the wind comes into contact with the occupant, a feeling like natural wind blowing can be obtained.

Further, a damper 14 is provided in the route of the air sucked by the blower 6, and the amount of ventilation is controlled by controlling the damper 14. Thereby, the outside air introducing machine 10 can take a required amount of outside air. Therefore, the heat load of the outside air on the circulation air conditioner 5 can be reduced.

The type of the dust filter 11 may be selected according to the required cleanliness.

In the present embodiment, the dust filter 11, the humidifier 12, and the heat exchanger 13 are provided in the outside air introducing device 10, but these devices are appropriately selected as needed, and one or more of them may be provided.
