Japanese Patent Application Publication No. 2009-139015

When performing a cooling operation using the air conditioning equipment of Patent Document 1, the cooling air generated by the indoor unit flows through the air conditioning duct, so it is conceivable that the temperature of the air conditioning duct becomes low. Therefore, when the outdoors is in a humid environment such as in the summer, if air containing moisture enters the underfloor space, condensation may occur on the surface of the air conditioning duct. In that case, problems such as mold growth in the air conditioning ducts may occur. In particular, when a building is provided with a ventilation opening for ventilating the underfloor space, it is thought that the above-mentioned problem is likely to occur because outside air containing moisture tends to enter the underfloor space through the ventilation opening.

An embodiment embodying the present invention will be described below with reference to the drawings. Note that FIG. 1 is a diagram showing a building equipped with an air conditioning system.

As shown in FIG. 1, a building 10 such as a residence is provided above a foundation 11. The foundation 11 is made of a cloth foundation made of reinforced concrete, and is provided over the entire outer periphery of the building 10. The building 10 is a two-story building, and the first floor thereof is provided with a plurality of rooms 12 to 14 and a machine room 15 in which an indoor unit 31 is installed. A floor section 17 is provided on the first floor of the building 10, and this floor section 17 forms the floor surfaces of the rooms 12 to 14 and the machine room 15. Note that the floor portion 17 includes a floor material and a floor beam that supports the floor material.

An underfloor space 18 is provided below the floor 17. The underfloor space 18 is vertically partitioned by the floor 17 from the rooms 12 to 14 and the machine room 15 (that is, the indoor space on the first floor). Further, the underfloor space 18 is surrounded by the foundation 11.

A ventilation opening 21 is provided between the foundation 11 and the building 10 to ventilate the underfloor space 18. A plurality of spacers 22 (see FIG. 2) are provided on the foundation 11 (more specifically, on the top of the foundation 11) at predetermined intervals in the direction in which the foundation 11 extends, and on top of these spacers 22, the building 10 is placed. A floor portion 17 (specifically, a floor beam) is placed on it. In this case, a gap corresponding to the height of the spacer 22 is formed between the foundation 11 and the floor part 17, and the above-mentioned ventilation port 21 is formed through this gap to communicate the underfloor space 18 with the outdoors. In addition, the code|symbol 25 in FIG. 2 is an outer wall part which partitions indoors and outdoors.

The building 10 is equipped with a whole-house air conditioning system 30. The air conditioning equipment 30 air-conditions each of the rooms 12 to 14 on the first floor of the building 10. The configuration of this air conditioning equipment 30 will be explained below. Note that the air conditioning equipment 30 corresponds to a "cooling equipment", and each room 12 to 14 corresponds to an "indoor space" that is cooled by the cooling equipment.

The air conditioning equipment 30 is a heat pump type air conditioning equipment, and is capable of performing at least cooling operation and heating operation. The air conditioning equipment 30 includes an indoor unit 31 provided indoors and an outdoor unit 32 provided outdoors. The indoor unit 31 and the outdoor unit 32 are connected via a refrigerant pipe 33, and in FIG. 1, the refrigerant pipe 33 is shown by a dotted line for convenience.

The indoor unit 31 takes in air from the machine room 15 and adjusts the temperature of the air to generate conditioning air (cooling air and heating air). That is, the indoor unit 31 generates cooling air by cooling the air taken in from the machine room 15 during cooling operation, and generates heating air by heating the air taken in from the machine room 15 during heating operation. .

The indoor unit 31 is connected to an air conditioning chamber 34 provided in the underfloor space 18. A plurality of air conditioning ducts 35 are connected to the air conditioning chamber 34. These air conditioning ducts 35, like the air conditioning chamber 34, are provided in the underfloor space 18 and extend toward each of the rooms 12 to 14 on the first floor. Note that the air conditioning chamber 34 and each air conditioning duct 35 correspond to air conveying members.

Each air conditioning duct 35 is connected to an air outlet 36 provided on the floor 17 of each room 12 to 14. The conditioned air generated by the indoor unit 31 is supplied to each outlet 36 through the air conditioning chamber 34 and each air conditioning duct 35, and the supplied conditioned air is blown out from each outlet 36 to each room 12 to 14, respectively. As a result, each room 12 to 14 is air-conditioned (cooled and heated).

Next, the configuration of the outdoor unit 32 will be explained based on FIG. 2. FIG. 2 is a perspective view showing the configuration around the outdoor unit 32.

The outdoor unit 32 discharges indoor heat outdoors as waste heat. As shown in FIG. 2, the outdoor unit 32 is installed outdoors adjacent to the foundation 11, with its back facing toward the foundation 11. The outdoor unit 32 is installed on a pair of blocks 38 that are spaced apart from each other on the ground in the left and right directions (specifically, in the left and right direction of the outdoor unit 32). In the installed state, the outdoor unit 32 is fixed to each block member 38 with bolts or the like. In addition, each block material 38 corresponds to a pair of support parts.

The outdoor unit 32 includes a casing 41 formed in the shape of a rectangular parallelepiped, a heat exchanger (not shown) built in the casing 41, and a fan 42 (see FIG. 3). The heat exchanger is connected to the refrigerant pipe 33 and causes heat exchange to occur between the refrigerant flowing through the refrigerant pipe 33 and the air inside the casing 41 . During cooling operation of the air conditioning equipment 30, the heat of the refrigerant is released into the casing 41 through the heat exchanger.

The fan 42 promotes heat exchange by the heat exchanger by generating air flow inside the housing 41. During cooling operation of the air conditioning equipment 30, release of heat from the refrigerant into the housing 41 via the heat exchanger is promoted.

An exhaust port 45 is provided on the front side (front side) of the casing 41 for discharging the air inside the casing 41 to the outdoors. When the fan 42 is activated, the air inside the housing 41 is exhausted to the outside through the exhaust port 45. As a result, during cooling operation of the air conditioning equipment 30, heat is released from the refrigerant into the housing 41 via the heat exchanger, and air containing the heat is discharged from inside the housing 41 to the outdoors through the exhaust port 45. Exhausted as air. Note that the housing 41 is provided with a fan guard 47 that prevents fingers from being inserted through the discharge port 45.

Here, the main building 10 is provided with an exhaust heat guide member 50 that guides exhaust heat air discharged from the outdoor unit 32 to the underfloor space 18 during cooling operation of the air conditioner 30. Hereinafter, the configuration regarding this exhaust heat guiding member 50 will be explained using FIGS. 3 and 4 in addition to FIG. 2. FIG. 3 is a sectional view showing the structure around the outdoor unit 32, and FIG. 4 is a perspective view showing the structure of the exhaust heat guiding member 50. In both FIGS. 3 and 4, (a) shows a state in which the front plate part 62 of the exhaust heat guiding member 50 is closed, and (b) shows a state in which the front plate part 62 is opened. (This point also applies to Figure 2).

As shown in FIGS. 2(a) to 4(a), the exhaust heat guiding member 50 includes a cover portion 51 provided on the front side of the outdoor unit 32 and covering a part of the exhaust port 45, and a cover portion 51 on the bottom surface of the outdoor unit 32. It has an extension part 52 that is provided on the side and extends to the underfloor space 18 through the foundation 11. The exhaust heat guide member 50 is formed as a whole into an L-shape in side view by the cover portion 51 and the extension portion 52. The exhaust heat guide member 50 is arranged such that the cover part 51 runs along the front surface of the outdoor unit 32 and the extension part 52 runs along the lower surface of the outdoor unit 32, and is fixed to the outdoor unit 32 in this arrangement state. .

The cover portion 51 covers the lower portion of the discharge port 45 from the front side. The extending portion 52 extends from the lower part of the cover portion 51 to the underfloor space 18 through between the blocks 38 . Specifically, a hole 53 penetrating in the thickness direction is formed in the foundation 11, and the extending portion 52 extends into the underfloor space 18 through the hole 53.

The exhaust heat guide member 50 has an air passage 55 therein, which takes in exhaust heat air discharged from the outdoor unit 32 and sends it to the underfloor space 18 . The air passage 55 extends in an L-shape across the cover portion 51 and the extension portion 52. An intake port 57 is formed in the cover portion 51 to take exhaust heat air discharged from the exhaust port 45 of the outdoor unit 32 into the air passage 55 . The intake port 57 is formed at a position facing the discharge port 45 and communicates the discharge port 45 with the air passage 55. Furthermore, an outlet port 58 is formed in the extending portion 52 for discharging exhaust heat air from the air passage 55 to the underfloor space 18 . The air passage 55 opens into the underfloor space 18 at the tip of the extending portion 52, and the opening serves as the outlet 58.

In the above configuration, a part of the exhaust heat air discharged from the exhaust port 45 of the outdoor unit 32 during cooling operation of the air conditioner 30 is taken into the air passage 55 through the intake port 57 of the exhaust heat guide member 50. Then, the taken-in exhaust heat air flows through the air passage 55 and is sent out to the underfloor space 18 from the outlet 58. In this case, since the temperature of the underfloor space 18 can be raised by the exhaust heat air sent to the underfloor space 18, the surface temperature of the air conditioning duct 35 and the air conditioning chamber 34 arranged in the underfloor space 18 can be raised. . Therefore, formation of dew condensation in the air conditioning duct 35 and the air conditioning chamber 34 can be suppressed. Note that the air in the underfloor space 18 that has become surplus due to the exhaust heat air being sent to the underfloor space 18 is discharged from the underfloor space 18 to the outdoors through the ventilation opening 21.

Next, the exhaust heat guiding member 50 will be further explained. The exhaust heat guide member 50 is made of, for example, hard resin, and includes a plurality of plate portions 61 to 65 that define an air passage 55. These plurality of plate portions 61 to 65 include a pair of L-shaped side plate portions 61 that face left and right with the air passage 55 in between, a front plate portion 62 provided in front of the air passage 55, and a front plate portion 62 provided in front of the air passage 55. A lower plate part 63 provided below, a top plate part 64 provided above the air passage 55 in the cover part 51, and an upper plate part 65 provided above the air passage 55 in the extension part 52. It is included.

The front plate portion 62 is provided on the opposite side of the air passage 55 from the intake port 57, and covers the exhaust port 45 of the outdoor unit 32 from the front side via the air passage 55 and the intake port 57. . The front plate part 62 is connected to the lower plate part 63 via a rotation shaft 67 at its lower end. The rotation shaft 67 is a shaft extending in the left-right direction. The front plate part 62 can be rotated forward about its rotation axis 67, and by this rotation, the front plate part 62 can be switched to a state in which it does not cover the discharge port 45 (the state shown in FIGS. 2(b) and 3(b)). is possible. That is, the front plate part 62 rotates between a closed position (positions shown in FIGS. 2(a) and 3(a)) where it covers the discharge port 45 and an open position (FIG. 2(a)) in which it does not cover the discharge port 45. b) and the position shown in FIG. 3(b)). As a result, when the air conditioning equipment 30 performs cooling operation, the front plate portion 62 can be placed in the closed position, and when the air conditioning equipment 30 performs heating operation, the front plate portion 62 can be placed in the open position. . Therefore, when the air conditioning equipment 30 performs a heating operation, by not covering the exhaust port 45, it is possible to avoid a decrease in the efficiency of exhaust heat from the outdoor unit 32, and as a result, the heating efficiency of the air conditioning equipment 30 can be avoided. can be avoided from decreasing. Note that in this case, the front plate portion 62 corresponds to the movable portion.

In this embodiment, the front plate section 62 is controlled to open and close by the control section 71. As shown in FIG. 3(b), the exhaust heat guiding member 50 is provided with a driving section 72 that rotationally drives the front plate section 62. As shown in FIG. The drive unit 72 is composed of, for example, an electric motor, and is driven and controlled by the control unit 71.

The control unit 71 is built into the indoor unit 31, for example. Information regarding the operating state of the indoor unit 31 is sequentially input to the control unit 71, and the control unit 71 determines whether the air conditioning equipment 30 is performing cooling operation or heating operation ( It is determined whether the air conditioning operation (equivalent to air conditioning operation other than cooling operation) is being performed. The control unit 71 controls the drive unit 72 to place the front plate 62 in the closed position when the air conditioning equipment 30 is performing cooling operation, and controls the driving unit 72 to bring the front plate 62 into the closed position when the air conditioning equipment 30 is performing heating operation. The drive unit 72 is controlled so that the unit 62 is in the open position. As a result, the outlet 45 of the outdoor unit 32 is covered by the front plate part 62 during the cooling operation of the air conditioner 30 (the state shown in FIGS. 2(a) and 3(a)), and the air conditioner 30 is in the heating operation. Sometimes, the discharge port 45 is not covered by the front plate part 62 (the state shown in FIGS. 2(b) and 3(b)). In this case, depending on whether the air conditioning equipment 30 is performing a cooling operation or a heating operation, covering/not covering the exhaust port 45 can be automatically switched, which is preferable in terms of convenience.

According to the configuration of this embodiment described in detail above, the following excellent effects can be obtained.

During the cooling operation of the air conditioner 30, the exhaust heat air discharged from the outdoor unit 32 is guided to the underfloor space 18 using the exhaust heat guide member 50. In this case, the temperature of the underfloor space 18 can be increased, and the surface temperature of the air conditioning duct 35 and the air conditioning chamber 34 (hereinafter referred to as the air conditioning duct 35 etc.) disposed in the underfloor space 18 can be increased. It is possible to suppress the formation of dew condensation.

In a building 10 that is provided with a ventilation opening 21 for ventilating the underfloor space 18, outside air containing moisture tends to enter the underfloor space 18 through the ventilation opening 21 when the outdoors is in a humid environment. Therefore, it is considered that dew condensation is likely to occur in the air conditioning duct 35 and the like during cooling operation. In this regard, in the above embodiment, since the exhaust heat air from the outdoor unit 32 is guided to the underfloor space 18 in such a building 10, it is possible to suitably suppress the formation of dew in the air conditioning duct 35, etc. in such a building 10. can do.

The exhaust heat air discharged from the outdoor unit 32 is sent to the underfloor space 18 through the air passage 55 of the exhaust heat guiding member 50. In this case, the exhaust heat air from the outdoor unit 32 can be guided to the underfloor space 18 without particularly changing the installation mode of the outdoor unit 32.

The exhaust heat guide member 50 was formed into an L-shape with a cover portion 51 and an extension portion 52. Then, the cover part 51 was arranged along the front surface of the outdoor unit 32, and the extending part 52 was arranged along the lower surface of the outdoor unit 32. In this case, since the exhaust heat guiding member 50 can be arranged without greatly protruding from the outdoor unit 32, it is possible to suppress the occurrence of inconveniences such as the exhaust heat guiding member 50 getting in the way.

In a configuration in which the outdoor unit 32 is placed and installed on a pair of block members 38 placed apart from each other on the left and right, the extension portion 52 of the exhaust heat guiding member 50 is placed on the lower surface side of the outdoor unit 32 on each block member. It is now placed throughout the 38 rooms. In this case, the spaces between the blocks 38 can be used effectively to prevent the extension portions 52 from becoming a hindrance.

The cover part 51 of the exhaust heat guide member 50 is provided so as to cover only a part of the exhaust port 45 of the outdoor unit 32. In this case, compared to the case where the cover portion 51 covers the entire exhaust port 45, it is possible to suppress a decrease in the efficiency of exhausting heat from the outdoor unit 32, and in turn, it is possible to suppress a decrease in cooling efficiency.

The present invention is not limited to the above embodiments, and may be implemented, for example, as follows.

- In the above embodiment, the cover part 51 of the exhaust heat guiding member 50 is provided to cover a part of the exhaust port 45 of the outdoor unit 32, but the cover part may be provided to cover the entire exhaust port 45. . In that case, all of the exhaust heat air discharged from the exhaust port 45 can be guided to the underfloor space 18, so that the temperature of the underfloor space 18 can be further increased. Therefore, formation of dew condensation in the air conditioning duct 35 and the air conditioning chamber 34 can be further suppressed. However, in this case, there is a risk that the efficiency of exhaust heat from the outdoor unit 32 will decrease, and as a result, the cooling efficiency of the air conditioning equipment 30 may decrease. Therefore, in view of this point, it is desirable to provide the cover portion 51 so as to partially cover the discharge port 45.

- In the above embodiment, the front plate part 62 of the exhaust heat guide member 50 is configured to be opened and closed depending on whether the air conditioning equipment 30 is performing cooling operation or heating operation, but this can be changed, for example. , a configuration may be adopted in which an operating section for opening and closing the front plate section 62 is provided and the opening and closing of the front panel section 62 is controlled based on the operation of the operating section. In this case, the user operates the operating section to open and close the front plate section 62 depending on whether the air conditioning equipment 30 is performing a cooling operation or a heating operation.

Further, the front plate portion 62 does not necessarily need to be opened and closed by the opening/closing control. In other words, the user may manually open and close the front plate portion 62 depending on whether the air conditioner 30 is performing a cooling operation or a heating operation. In this case, since the drive section 72 and the control section 71 can be made defective, the configuration can be simplified.

- In the above embodiment, the extension part 52 of the exhaust heat guide member 50 is placed through the bottom side of the outdoor unit 32, but if space cannot be secured on the bottom side of the outdoor unit 32, the extension part 52 can be placed through the bottom side of the outdoor unit 32. It may be arranged through the side or top side of 32.

- The exhaust heat guide member 50 does not necessarily need to be configured to include the cover portion 51 and the extension portion 52. For example, the exhaust heat guide member may be formed of a flexible duct (bellows duct). In this case, the opening at one end of the flexible duct is directed toward the outlet 45 of the outdoor unit 32, and the flexible duct is bent so that the other end of the flexible duct extends toward the foundation 11. Then, the other end of the flexible duct is inserted into a hole provided in the foundation 11. In this configuration, the exhaust heat air discharged from the exhaust port 45 of the outdoor unit 32 is taken in through the opening at one end of the flexible duct, and the exhaust heat air is guided to the underfloor space 18 through the inside of the duct (corresponding to the air passage). It will be destroyed. In this case, the exhaust heat guiding member can be constructed relatively easily using an existing flexible duct. However, in this case, there is a risk that the flexible duct will largely protrude to the front side of the outdoor unit 32 and become an obstruction. Preferably, it constitutes a member.

- An airflow generating means may be provided in the air passage 55 of the exhaust heat guiding member 50 to generate a flow of air toward the underfloor space 18. For example, a fan device can be used as the airflow generating means. In this case, the exhaust heat air discharged from the outdoor unit 32 can be actively guided to the underfloor space 18 through the air passage 55. Therefore, the temperature of the underfloor space 18 can be increased.

- A configuration other than the exhaust heat guiding member 50 may be adopted as a means (exhaust heat guiding means) for guiding the exhaust heat air discharged from the outdoor unit 32 to the underfloor space 18. For example, a configuration can be considered in which the outdoor unit 32 is installed so that the outlet 45 faces the foundation 11, and a hole is provided in the foundation 11 at a position facing the outlet 45 to communicate the underfloor space 18 with the outdoors. In this case, the exhaust heat air discharged from the outlet 45 of the outdoor unit 32 is guided to the underfloor space 18 through the hole in the foundation 11. In addition, in this structure, the hole of the foundation 11 corresponds to an exhaust heat guide means.

・Some air conditioning equipment is capable of dehumidifying operation. In such air conditioning equipment, cooling air may be generated by the indoor unit during dehumidification operation, and in that case, there is a possibility that dew condensation may occur in the air conditioning duct 35 even during dehumidification operation. In this regard, according to the configuration of the above embodiment using the exhaust guide member 50, it is possible to suppress dew condensation from forming in the air conditioning duct 35 even during dehumidification operation.

・Some air conditioning equipment is only capable of cooling operation. Therefore, the present invention may be applied to such air conditioning equipment (that is, cooling equipment).

- Although the building 10 of the above embodiment was provided with the ventilation port 21 for ventilating the underfloor space 18, there may be cases where such a ventilation port 21 is not provided depending on the building. However, even in such a building, it is assumed that outside air containing moisture may enter the underfloor space 18, and in that case, if the present invention is applied, it is possible to suppress the formation of dew on the air conveying member within the underfloor space 18. .
