Description

  The present invention relates to an air conditioner that eliminates the need for a blower that blows out heat exchange air from a blowout port to a room.

  In recent years, there has been a marked improvement in the air-conditioning effect of air conditioners, but on the other hand, if the heat exchange air blown from the outlet directly hits the body, it is too cold during cooling operation and too hot during heating operation I feel an uncomfortable feeling called a draft. Therefore, if the set temperature in the cooling is increased or the set temperature in the heating is decreased, it is difficult to obtain the air conditioning effect at a position away from the outlet.

  If more outlets are provided to eliminate the sense of perspective with respect to the outlet position, there is an expectation that the air conditioning effect will be averaged and the difference in temperature experienced by humans will diminish. However, in this case, the blowing sound of the blower that blows out the heat exchange air from the blowout opening is easily heard as noise, and the quietness of the entire air-conditioned space is hindered.

  For example, [Patent Document 1] discloses an attracting and mixing type air blowing device. This blowing device blows out heat exchange air, which is guided from an air conditioner fan through a duct, from a nozzle port as primary air. In this state, the air in the vicinity of the nozzle is fed while being taken in as induction air (secondary air), and the mixed air is blown out into the room from the outlet.

  According to the blowing device described in the above [Patent Document 1], it is possible to blow into the room without arranging a blower at the blowing port, and there is no leakage of blowing noise into the room. Further, since the blowing device is integrally provided with the connecting portion between the blowing port portion and the duct, it can be easily attached even after the ceiling construction when arranged on the ceiling.

  However, in this blow-out device, it is necessary to separately arrange the indoor unit constituting the large-sized air conditioner in the indoor dedicated space and to arrange the outdoor unit in the outdoor dedicated space. Thereby, there are many restrictions when installing the air conditioner, which is not particularly suitable for small and medium buildings.

  In addition, it is necessary to carry out heat insulation work by wrapping a heat insulating material around the duct that connects the indoor unit arranged in the dedicated space and the blowing device provided in the air-conditioned room, which increases the cost of parts and work. Affect.

  The present invention has been made based on the above circumstances, and an object of the present invention is to eliminate the need for a blower for blowing heat exchange air into the indoor unit in the indoor unit, to improve the quietness of the room, and to improve the indoor unit. It is intended to provide an air conditioner that can increase the degree of freedom of installation by integrating the outdoor unit and the outdoor unit.

  In order to satisfy the above object, the present invention provides an indoor heat exchanger, an air supply duct provided with a plurality of outlets provided along one side surface of the indoor heat exchanger, and the other side surface of the indoor heat exchanger. It is provided with an indoor air introduction path for introducing indoor air, and the indoor air introduced into the indoor air introduction path is circulated through the indoor heat exchanger by the attracting action of the air ejected from the ejection outlet, and heat is exchanged to be ejected from the ejection outlet. An indoor unit that leads to the room together with the air to be moved, a compressor, an outdoor heat exchanger, and an expansion device, and the indoor heat exchanger of the inner unit and the outdoor unit that constitutes the refrigeration cycle are integrated into the air conditioner body. .

  According to the present invention, an air blower is not required in the indoor unit to improve the quietness of the room, and the indoor unit and the outdoor unit are integrated into the air conditioner body to increase the degree of freedom of installation. There are effects such as.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional plan view of an air conditioner for a building according to a first embodiment of the present invention.

  The building K, which is the installation location of the air conditioner, is provided with a plurality of air-conditioned rooms (rooms) R arranged on both sides of a passage T provided in the center, for example. Note that doors, windows, stairs and landings, elevators, verandas, etc. necessary for the building K are all omitted, and are shown as simple partition spaces.

  The air conditioner main body 1 described later is attached to the wall surface or ceiling surface of each air-conditioned room R. An air supply duct 2 is provided along one side of the air conditioner main body 1, and an exhaust duct 3 is provided along the other side. Therefore, one air supply duct 2 and one exhaust duct 3 are provided for each of the air conditioner main bodies 1 on one side of the passage T.

  Each of the left and right air supply ducts 2 is bent at one side of the building K so as to follow the inner wall surface of the building K, and is connected to the main air supply duct 2A from two directions at a site above the passage T. To do. The main air supply duct 2A penetrates the outer wall from the inside of the building K, protrudes to the outside and opens, and the air supply fan 4 is accommodated in the inside.

  On the other hand, the left and right exhaust ducts 3 are formed to bend along the inner wall surface of the building K on the other side of the building K, and connect to the main exhaust duct 3A from two directions at the upper part of the passage T. . The main exhaust duct 3A penetrates through the outer wall from the inside of the building K and protrudes to the outside, and the exhaust blower 5 is accommodated in the interior.

  Further, the air supply duct 2 is provided with a branch air supply duct 2 a extending into the air conditioner body 1. Similarly, a branch exhaust duct 3 a is branched from the exhaust duct 3 and connected to one side of the air conditioner body 1.

  Therefore, the air supply blower 4 accommodated in the main air supply duct 2A sucks outside air by being driven and blows air from the main air supply duct 2A to the air supply duct 2, and further for branch supply. The air can be blown into the air conditioner body 1 from the duct 2a.

  Further, the exhaust blower 5 accommodated in the main exhaust duct 3A is driven to suck the air inside the air conditioner body 1 from the branch exhaust duct 3a and guide it to the exhaust duct 3, and further to the main exhaust. The air can be exhausted from the duct 3A.

FIG. 2 is a schematic cross-sectional plan view of the air conditioner main body, and FIG. 3 is a schematic vertical cross-sectional view of an indoor unit constituting the air conditioner main body.
The interior of the air conditioner main body 1 that is a housing is partitioned by a partition plate 6, one partitioned internal space constitutes an indoor unit 7, and the other constitutes an outdoor unit 8. Each of the indoor unit 7 and the outdoor unit 8 has a heat insulating structure in which a heat insulating material is attached along the inner wall.

  A branch air supply duct 2 a branched from the air supply duct 2 has a circular cross section, is inserted from one side of the indoor unit 7, and extends to the vicinity of the partition plate 6. In other words, the branch air supply duct 2a is provided at a substantially central portion in the width direction of the indoor unit 7 and in contact with the upper end surface, and the front end opening is closed by a cover plate.

  A plurality of jet nozzles (spout ports) 10 are provided at substantially the same angular positions distributed left and right from the upper end of the branch air supply duct 2a with a predetermined interval along the axial direction of the branch air supply duct 2a. Provided.

  That is, the jet nozzles 10 are attached to the branch air supply ducts 2a in two rows, and each of the jet nozzles 10 is slanted from the connecting portion with the branch air supply duct 2a, which is the base end portion, to the front end. It protrudes in a state of being directed downward.

  In particular, as shown in FIG. 3, an inner wall portion 7 a of the indoor unit 7 is provided in accordance with the inclination angle of the ejection nozzle 10, and the inner wall portion 7 a is formed in a substantially C-shaped cross section in a side view. And the indoor heat exchanger 12 is provided in parallel with the inner wall part 7a at a predetermined interval, and, like the inner wall part 7a, is arranged in a substantially C shape in a side view.

  The inclination angles of the ejection nozzle 10, the inner wall 7 a of the indoor unit 7, and the indoor heat exchanger 12 are all the same, and the ejection nozzle 10 is located between the indoor unit inner wall 7 a and the upper surface of the indoor heat exchanger 12. Tilt to erupt toward the space.

  The lower end surface of the indoor unit 7 is open and is closed by the decorative board 13. A suction port 15 is opened at the center of the decorative plate 13, and a blowout port 16 is opened along both sides of the suction port 15. Both the one inlet 15 and the two outlets 16 are provided over the width direction of the indoor unit 7 and have a horizontally long rectangular shape.

  Two drain pans 17 are placed on the decorative plate 13, and the indoor heat exchanger 12 is placed on each drain pan 17. The suction port 15 opens between the drain pans 17, and the blowout port 16 opens between the side end of each drain pan 17 and the side end of the indoor unit 7. With the above configuration, a space from the suction port 15 to the lower surface of the indoor heat exchanger 12 is formed as the indoor air introduction path 18.

  In the outdoor unit 8, an exhaust port is provided on a side surface facing the through surface of the branch air supply duct 2 a for the indoor unit 7, and the branch exhaust duct 3 a is connected thereto. A ventilation flow introduction port 19 is provided on one side surface of the outdoor unit 8 in a direction orthogonal to the connection surface of the branch exhaust duct 3a and opens to the air-conditioned room R.

  Inside the outdoor unit 8, a compressor 20, an outdoor heat exchanger 21 and an expansion valve (expansion device) 22 are accommodated. The compressor 20, the outdoor heat exchanger 21, and the expansion valve 22 are connected to constitute a refrigeration cycle via the indoor heat exchanger 12 and the refrigerant pipe P. Therefore, a set of refrigeration cycle components is housed in the air conditioner body 1.

  The air conditioner configured as described above drives the compressor 20 and also drives the air supply fan 4 in the main air supply duct 2A and the exhaust air fan 5 in the main exhaust duct 3A. Thus, the cooling operation for the air-conditioned room is started.

  A high-temperature and high-pressure gas refrigerant is discharged from the compressor 20 and exchanges heat with the outdoor heat exchanger 21 as described later to be condensed and liquefied. The liquid refrigerant is adiabatically expanded by the expansion valve 22, evaporates by exchanging heat with the secondary air in the indoor heat exchanger 12, as will be described later, and takes latent heat of evaporation from the secondary air to change into cold air. The evaporated refrigerant is guided to the compressor 20 and circulates again through the above-described refrigeration cycle.

  On the other hand, outside air is sucked into the main air supply duct 2 </ b> A by driving the air supply fan 4. The outside air is guided from the main air supply duct 2A to the ejection nozzle 10 through the air supply duct 2 and the branch air supply duct 2a. Since the diameter of the ejection nozzle 10 is extremely small compared to the diameter of the branch air supply duct 2a, the flow rate is reduced in the ejection nozzle 10, and the outside air is ejected from the ejection nozzle 10 with a faster flow velocity.

  A jet flow from the jet nozzle 10 is formed in a space portion between the indoor unit inner wall 7 a and the upper surface of the indoor heat exchanger 12. Since the blowout port 16 is provided at the lower end of the indoor unit 7 facing the tip of the blowout nozzle 10, the blowout flow is blown out toward the blowout port 16. As a result, the space between the inner wall 7a of the indoor unit and the upper surface of the indoor heat exchanger 12 becomes negative pressure.

  The air on the lower surface side of the indoor heat exchanger 12 is attracted by the jet flow, and the indoor air is guided into the indoor unit 7 from the suction port 15. Then, the indoor heat exchanger 12 is circulated through the indoor air introduction path 18. Then, it joins with the said jet flow in the upper surface side of the indoor heat exchanger 12, and goes to the blower outlet 16 as a mixed flow.

  The outside air ejected from the ejection nozzle 10 along the upper surface of the indoor heat exchanger 12 is used as primary air, and the indoor air that is guided from the suction port 15 to the indoor air introduction path 18 and flows from the lower surface to the upper surface of the indoor heat exchanger 12 is secondary. As air, secondary air is attracted to primary air. The indoor heat exchanger 12 exchanges heat with the secondary air and converts it into cold air.

  The cool air, which is the secondary air, is mixed with the primary air, slightly rises in temperature, is led to the blowout port 16, and is further blown into the room to perform a cooling action on the air-conditioned room R. At this time, if air is blown into the indoor space at a speed of 0.1 m / s or less, cooling without airflow is achieved.

  Since the heat exchange air blown out to the air-conditioned room R is a mixed airflow by induction, the temperature of the indoor heat exchanger (evaporator) 12 is lowered as much as possible to ensure a dehumidification amount. Then, an appropriate temperature is jetted into the indoor space with the induced mixed airflow to prevent overcooling.

  The air after cooling the air-conditioned room R circulates in the room. On the other hand, since the exhaust fan 5 is driven, the pressure in the outdoor unit 8 is reduced to negative pressure via the branch exhaust duct 3a. Therefore, a part of the indoor air is introduced into the outdoor unit 8 from the ventilation flow inlet 19 provided in the outdoor unit 8.

  In the outdoor unit 8, the indoor air introduced from the ventilation flow inlet 19 flows through the outdoor heat exchanger 21 and exchanges heat. Thereafter, the air is exhausted outdoors via the branch exhaust duct 3a, the exhaust duct 3, and the main exhaust duct 3A. In buildings such as offices, it is necessary to obtain a ventilation flow stipulated in the Building Management Law, and heat exchange with the outdoor heat exchanger 21 is performed using this ventilation flow.

  Thus, while installing the air conditioner body 1 in which the indoor unit 7 and the outdoor unit 8 are integrated in the room, an indoor blower that blows heat exchange air to the indoor heat exchanger 12 is not required, and outdoor heat exchange is performed. An outdoor fan that blows heat exchange air to the chamber 21 is also unnecessary. The blowing sound that leaks from the air conditioner main body 1 to the air-conditioned room R is completely eliminated, and the room can be quieted and air-conditioning without airflow can be achieved.

  Since the indoor unit 7 and the outdoor unit 8 are integrally provided in the air conditioner body 1, the installation location of the air conditioner body 1 in the air-conditioned room R can be selected as appropriate, and the degree of freedom of installation is expanded. To do.

Of course, a four-way valve may be added to the refrigeration cycle in the above-described embodiment to enable switching to not only cooling operation but also heating operation, and at this time, the above-described effects can be obtained.
When the air-conditioned room R is wide, a plurality of air conditioner main bodies 1 may be provided. Furthermore, the outside air sucked from the main air supply duct 2A may be air whose temperature has been adjusted in advance by an air conditioner separately provided outside the building K.

FIG. 4 is a schematic longitudinal sectional view of an indoor unit constituting the air conditioner according to the second embodiment of the present invention.
Only the configuration of the indoor unit 7A, which will be described later, is different, and there is no change in the other components, so that a new description is omitted by applying FIGS.

  Here, the jet nozzle 10A provided in the branch air supply duct 2a projects from the branch air supply duct 2a toward the lower part, and a jet flow is formed immediately below the jet nozzle 10A. Guide plates 25 project in a substantially horizontal direction from the inner side surfaces of the left and right drain pans 17 on which the indoor heat exchanger 12 is placed, and the tips of the guide plates 25 face each other with a gap therebetween.

  The jet outlet of the jet nozzle 10A is opposed to the upper part of the guide plate 25, and a flat plate 26 having a substantially triangular cross section is provided in the lower part of the guide plate 25. Therefore, the jet flow formed from the jet nozzle of the jet nozzle 10A is configured to collide with the flat plate 26 through the interval between the guide plates 25.

  The flat plate 26 is provided in the decorative plate 13 that closes the opening on the lower surface of the indoor unit 7 </ b> A. The indoor unit is a side end portion of the decorative plate 13 with the outlet 16 </ b> A opening along both sides of the flat plate 26. A suction port 15A is opened between the lower end of 7A. The two outlets 16A and the inlet 15A are formed so as to form a horizontally long rectangular shape.

  Although the inclination angle of the indoor heat exchanger 12 disposed obliquely is not different from that described above, the inclination angle of the indoor unit inner wall portion 7b facing the upper surface of the indoor heat exchanger 12 is described above. It is formed loosely.

  That is, the upper end of the inner wall portion 7b is very close to the upper end of the upper surface of the indoor heat exchanger 12, and is separated from the upper surface of the indoor heat exchanger 12 toward the lower side. Separate from the heat exchanger 12. Here, the space between the upper surface of the indoor heat exchanger 12 and the inner wall 7b is the indoor air introduction path 18A.

  The air conditioner includes the indoor unit 7A configured as described above, drives the compressor 20 to perform a refrigeration cycle operation, and supplies the air supply blower 4 in the main air supply duct 2A and the main exhaust. The exhaust fan 5 in the air duct 3A is driven. Since operations other than the indoor unit 7A are as described above, a new description is omitted.

  As the air supply fan 4 is driven, outside air is ejected from the ejection nozzle 10 </ b> A in the indoor unit 7 </ b> A, and an ejection flow is formed between the ejection nozzle 10 </ b> A and the flat plate 26. The air on the upper surface side of each indoor heat exchanger 12 is attracted and flows through the indoor heat exchanger 12. This circulating air is indoor air that is guided from the suction ports 15A on both sides to the indoor air introduction path 18A.

  That is, indoor air is attracted as secondary air to the primary air ejected from the ejection nozzle 10 </ b> A and exchanges heat with the indoor heat exchanger 12. The secondary air is mixed with the primary air immediately after exchanging heat with the indoor heat exchanger 12, becomes a mixed air current, passes through the space between the guide plates 25, and collides with the flat plate 26.

The mixed airflow is divided into two parts from the cross-sectional shape of the flat plate 26, and blown out into the room from the outlets 16A on both sides of the flat plate 26. As described above, the jet flow can be diffused by the presence of the flat plate 26 having a substantially triangular cross section, and the comfort for the air conditioning function in the room can be improved.
In addition, since the indoor air introduction path 18A is formed so as to be gradually narrowed from the suction port 15A, partial deviation of the heat exchange efficiency in the indoor heat exchanger 12 can be prevented. In addition, the same effects as those of the above-described embodiment can be obtained.

  FIG. 5 is a schematic cross-sectional plan view of an air conditioner for a building according to a third embodiment of the present invention. Except for the air supply duct 2 described later and the configuration related thereto, the other configurations are the same as those described above with reference to FIG. 1, so the same parts are denoted by the same reference numerals and the new description is omitted. .

  In FIG. 1, the main air supply duct 2 </ b> A is provided through the outer wall of the building K, and the external air is introduced so as to supply the primary nozzle to the ejection nozzle 10 in the indoor unit 7. It is not something.

  The air supply ducts 2 on the left and right sides are bent at one side in the building K and intersect at an upper portion of the passage T. At a position where these air supply ducts 2 intersect, a main air supply duct 2B with the axial direction oriented vertically is provided. In short, the main air supply duct 2B may be provided inside the building K.

  One of the upper and lower ends of the main air supply duct 2B is opened, and the other end is closed. An air supply blower 4 is housed inside, and the air sucked from the opening of the main air supply duct 2 </ b> B can be blown to the left and right air supply ducts 2. Furthermore, since the general building K has high airtightness, a small window 27 for taking in outside air is provided in the building K portion separated from the main air supply duct 2B.

By driving the air supply fan 4, the air circulated mainly inside the building K is sucked into the main air supply duct 2 </ b> B. The sucked air is guided from the air supply duct 2 to the branch air supply duct 2a and is ejected from the ejection nozzle 10 to obtain the above-described operational effects.
At the same time, outside air is taken in through the small window 27 and sucked into the main air supply duct 2B. That is, in the previous embodiment, the outside air is used as primary air and mixed with the heat-exchanged secondary air, so there is a certain temperature difference between the primary air and the secondary air.

On the other hand, in the third embodiment, the air in the air-conditioned room R is used as the primary air, so that the temperature difference from the secondary air (heat exchange air) is further reduced, and the indoor heat exchanger 12 The heat exchange efficiency can be further improved.
On the other hand, a ventilation flow is used as heat exchange air for exchanging heat with the outdoor heat exchanger 21, and after the heat exchange, the air is exhausted to the outside through the exhaust duct 3. In addition, the same effects as those of the above-described embodiment can be obtained.

FIG. 6 is a schematic cross-sectional plan view of an air conditioner according to the fourth embodiment.
In this embodiment, it is applied as an air conditioner provided in each air-conditioned room R, and the air supply / exhaust ducts 2 across the air-conditioned rooms R in the left and right rows as in the embodiments described so far. The entire building K with 3 is not targeted.

  The interior of the air conditioner main body 1 </ b> A is partitioned into an indoor unit 7 and an outdoor unit 8 through a partition plate 6. The configurations of the indoor heat exchanger 12, the ejection nozzle 10 (or 10A), and the decorative plate 13 provided in the indoor unit 7 are the same as those described above with reference to FIG. 3 (or FIG. 4).

The air conditioner main body 1 is attached to the wall surface of the air-conditioned room R, but may be attached to the back of the ceiling. The air supply duct 2c provided with the ejection nozzle 10 passes through the outer wall a of the air-conditioned room R, and this open end is exposed to the outside. An air supply blower 28 is accommodated in the air supply duct 2c, and external air can be introduced and air can be supplied to the ejection nozzle 10 with this driving.
Alternatively, the opening end of the air supply duct 2c may be opened indoors, and the air supply fan 28 may be driven to supply the indoor ventilation flow to the ejection nozzle 10.

  On the other hand, in the outdoor unit 8, a compressor 20 constituting the refrigeration cycle, an outdoor heat exchanger 21, and an expansion valve 22 are disposed inside the outdoor unit 8, and the indoor unit 7 via the indoor heat exchanger 12 and the refrigerant pipe P are disposed. Therefore, there is no change in communicating to constitute a refrigeration cycle.

  Similarly, a ventilation flow inlet 19 that uses indoor air is provided as heat exchange air that is guided to the outdoor heat exchanger 21. An exhaust port 3b for exhausting the air after heat exchange with the outdoor heat exchanger 21 passes through the outer wall a of the air-conditioned room R and is exposed to the outside.

  An outdoor blower 30 is disposed to face the outdoor heat exchanger 21. By driving the outdoor blower 30, indoor air is introduced into the outdoor unit 8 from the ventilation flow inlet 19, and is blown to the outdoor heat exchanger 21 for heat exchange. The air after the heat exchange with the outdoor heat exchanger 21 is exhausted to the outside from the exhaust port 3b.

  That is, in this embodiment, since the outdoor fan 30 is provided in the outdoor unit 8, it is inevitable that a certain amount of blowing noise leaks into the room, but on the other hand, the heat exchange efficiency in the outdoor heat exchanger 21 is greatly improved. The outdoor blower 30 also functions as a ventilation fan.

  Further, as in the embodiment described above, the relationship between the air supply / exhaust ducts 2 and 3 across the left and right air-conditioned rooms R and the air conditioner body 1 is eliminated, and the air conditioner body 1A is singulated. It can be installed at any place in the air-conditioned room, and installation work can be greatly improved.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
