Detailed Description
Hereinafter, a ceiling-embedded indoor unit according to an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 is a longitudinal sectional view of a ceiling-embedded indoor unit according to an embodiment of the present invention. Fig. 2 is a bottom view of the ceiling-embedded indoor unit of the embodiment of the present invention viewed from the indoor side. Fig. 3 is a sectional view of the periphery of a flap of the ceiling-embedded indoor unit according to the embodiment of the present invention.
In the present embodiment, as shown in fig. 1, the ceiling-embedded indoor unit 10 is provided in a ceiling space 13 between a ceiling 11 of a house and a ceiling 12 provided below the ceiling 11.
As shown in fig. 1, the ceiling-embedded indoor unit 10 includes a box-shaped air conditioner main body 14 whose lower surface is open, and the air conditioner main body 14 is hung from the ceiling by means of hanger bolts 15. A heat insulating member 16 made of expanded styrene is disposed inside the air conditioner main body 14 in contact with the inner surfaces of the side plate 17a and the upper plate 17b of the air conditioner main body 14, thereby preventing condensation on the side plate 17a and the upper plate 17 b.
A fan motor 21 is attached to a lower surface of the upper plate 17b of the air conditioner main body 14, and a rotary shaft 22 that is rotationally driven by driving the fan motor 21 is provided to extend downward in the fan motor 21. An impeller 23 is attached to a lower end portion of the rotary shaft 22, and the fan motor 21 and the impeller 23 constitute an air blower 20.
Between the air blowing device 20 and the heat insulating member 16 in contact with the side plate 17a, a heat exchanger 18 formed by bending in a quadrangular shape in plan view is disposed so as to surround the side of the air blowing device 20.
The heat exchanger 18 functions as an evaporator of the refrigerant during the cooling operation and functions as a radiator of the refrigerant during the heating operation. The heat exchanger 18 is configured to exchange heat between the air in the air-conditioning room sucked into the air conditioner main body 14 and the refrigerant, to cool the air in the air-conditioning room during the cooling operation, and to heat the air in the air-conditioning room during the heating operation. Here, the air-conditioning room is a room to be air-conditioned, and in the description of the present embodiment, is a room in which the ceiling-embedded indoor unit of the present embodiment is installed on the ceiling.
Further, a drain pan 19 is disposed below the heat exchanger 18 so as to correspond to the lower surface of the heat exchanger 18. The drain pan 19 receives drain water generated by the heat exchanger 18. Further, a suction port 24 of the blower 20 is formed in the central portion of the drain pan 19.
As shown in fig. 1 and 2, a decorative plate 25 having a substantially rectangular shape in plan view is attached to the lower surface of the air conditioner 14 so as to cover the lower opening of the air conditioner main body 14.
A suction port 26 communicating with the suction port 24 of the drain pan 19 is formed in the center portion of the decorative plate 25, and a suction grill 27 covering the suction port 26 is detachably attached to the suction port 26. A filter 28 for removing dust and the like in the air is provided on the air conditioner main body 14 side of the suction grill 27.
An air outlet 29 for delivering conditioned air into the air-conditioned room is formed at a position outside the air inlet 26 of the decorative panel 25 and along each side of the decorative panel 25. When the rotary shaft 22 is rotated and driven by the fan motor 21 to rotate the impeller 23, indoor air is sucked from the suction port 26, passes through the filter 28 and the suction port 24, exchanges heat with the heat exchanger 18, and is sent from the discharge port 29 into the air-conditioned room.
As shown in fig. 2 and 3, each air outlet 29 is provided with a flap 30 that changes the angle of the air flow in the vertical direction. Support shafts (not shown) are provided at both end portions of each pendulum piece 30. The swing piece 30 is mounted to the air outlet 29 so as to be rotatable about the support shaft by supporting the support shaft on both end sides of the air outlet 29. Further, a hinge portion 31 is provided at a substantially center in the longitudinal direction of the back surface (surface on the air conditioner main body 14 side) of each flap 30. The hinge portion 31 can be driven by a flap driving motor 32 (see fig. 4), and the flaps 30 can be driven to rotate independently of each other.
In the present embodiment, the swing piece 30 is configured to be adjustable in angle in 5 shift positions from the 1 st shift position (F1) to the 5 th shift position (F5). The 1 st gear is a position where the angle relative to the horizontal plane is minimum and the air is blown out laterally, and the 5 th gear is a position where the angle relative to the horizontal plane is maximum and the air is blown out substantially directly below.
Further, a floor temperature sensor 33 and a human detection sensor 34 are attached to the corners of the decorative panel 25. The floor temperature sensor 33 detects the temperature of the floor surface in the air-conditioned room, and the human detection sensor 34 detects the presence or absence of a human or the position of a human in the air-conditioned room.
Next, a control structure of the present embodiment will be explained.
Fig. 4 is a block diagram showing a control structure of the ceiling-embedded indoor unit according to the present embodiment. As shown in fig. 4, the present embodiment includes a control unit 40 configured from, for example, a CPU, a memory, and the like, and operated based on a predetermined program, and the control unit 40 controls the operation of each device constituting the ceiling-embedded indoor unit 10.
Further, a floor temperature sensor 33 that detects the floor temperature in the air-conditioned room and a human detection sensor 34 that detects a human in the air-conditioned room are connected to the control unit 40, respectively. The control unit 40 receives as input the floor temperature in the air-conditioned room detected by the floor temperature sensor 33 and the detection result of the presence or absence of a person detected by the person detection sensor 34, and controls the operations of the fan motor 21 and the flap drive motor 32.
For example, the control unit 40 drives the fan motor 21 to operate the air blower 20 in accordance with the temperature of the floor detected by the floor temperature sensor 33, based on an instruction transmitted from a remote controller, not shown, placed in the air-conditioned room. The control unit 40 controls the swinging of the flap 30 based on the presence or absence of a person or the position of the person detected by the person detection sensor 34 based on an instruction transmitted from a remote controller, not shown, installed in the air-conditioned room, so that the flap 30 can blow air toward the person.
Here, in the present embodiment, the control unit 40 is configured to perform the circulation operation of the air in the mixing chamber when the temperature of the floor detected by the floor temperature sensor 33 becomes a certain temperature or lower during the cooling operation.
Fig. 5A and 5B are explanatory diagrams illustrating an operation of the circulation operation. Fig. 6A and 6B are timing charts showing the operation of each of the flaps 30 during the circulation operation.
As shown in fig. 5A and 6A, in the present embodiment, the circulation operation includes 3 steps (1 st step to 3 rd step) according to the rotational position of the flap 30. Here, the 4 pendulum pieces 30 are rotated, and among the pair of pendulum pieces 30 facing each other, a pair of the pendulum pieces 30 is a 1 st pair of pendulum pieces 30a, and the other pair is a 2 nd pair of pendulum pieces 30b, which will be described below.
The 1 st step is an operation of blowing air for a certain period of time by positioning the 1 st pair of the swing pieces 30a facing each other at the 5 th shift position (F5) and positioning the 2 nd pair of the swing pieces 30b at the 3 rd shift position (F3).
The 2 nd step is an operation of blowing air for a certain period of time with all the swing pieces 30 (the 1 st pair of swing pieces 30a and the 2 nd pair of swing pieces 30b) being in the 5 th shift position (F5).
The 3 rd step is an operation of performing air blowing for a certain time by positioning the 1 st pair of swing tabs 30a positioned at the 5 th shift position (F5) in the 1 st step at the 3 rd shift position (F3) and positioning the 2 nd pair of swing tabs 30b positioned at the 3 rd shift position (F3) in the 1 st step at the 5 th shift position (F5).
In the present embodiment, the control unit 40 performs control so that the 2 nd step and the 3 rd step are performed in order from the 1 st step, and after the 3 rd step, the 2 nd step and the 1 st step are performed in a reverse manner. That is, in the present embodiment, the 2 nd step of positioning all the swing pieces 30 in the 5 th speed (F5) is inserted between the 1 st step and the 3 rd step, and the control is performed.
In the present embodiment, the air blowing is performed in the combination of the 5 th gear (F5) and the 3 rd gear (F3) in the 1 st step and the 3 rd step, but the present invention is not limited thereto.
That is, in the present embodiment, the 1 st gear position and the 2 nd gear position are set at angles at which the person located indoors is not touched by wind among the 1 st gear position to the 5 th gear position, and therefore the 3 rd gear position (F3) is used as a position at which the person receives wind and the angle is the smallest. Therefore, even when the settable wind direction angle of the swing piece 30 is, for example, 6 steps or more, the combination of the 4 th step and the 6 th step can be performed. In addition, when the settable wind direction angle of the swing piece 30 is, for example, 4 stages, it can be performed by a combination of the 2 nd stage and the 4 th stage.
Further, another operation in step 1 will be described with reference to fig. 5B and 6B, for example. Here, the 4 pendulum pieces 30 are rotated, and among the adjacent pairs of pendulum pieces 30, the 1 st pair of pendulum pieces 30c is defined as one pair of adjacent pendulum pieces 30, and the 2 nd pair of pendulum pieces 30d is defined as the other pair of adjacent pendulum pieces 30, which will be described below.
The 1 st step is an operation of blowing air for a certain period of time with the adjacent 1 st pair of the flaps 30c in the 5 th shift position (F5) and the 2 nd pair of the flaps 30d in the 3 rd shift position (F3). The 3 rd step at this time is an operation of blowing air for a certain period of time with the 1 st pair of swing tabs 30c located at the 5 th shift position (F5) in the 1 st step being located at the 3 rd shift position (F3) and the 2 nd pair of swing tabs 30d located at the 3 rd shift position (F3) in the 1 st step being located at the 5 th shift position (F5).
The operation of the cyclic operation can be set to any of the above-described operations.
Next, the operation of the present embodiment will be described with reference to a flowchart shown in fig. 7.
In the present embodiment, when the heating operation is performed (step ST1), if the floor temperature detected by the floor temperature sensor 33 is equal to or lower than a certain value (step ST2), the circulation operation is started (step ST 3).
As described with reference to fig. 5A and 6A, the circulation operation is performed in step 1, and air blowing is performed for a predetermined time period while the 1 ST pair of flaps 30a facing each other are positioned at the 5 th shift position (F5) and the 2 nd pair of flaps 30b are positioned at the 3 rd shift position (F3) (step ST 4).
Subsequently, the operation of step 2 is performed, and air blowing is performed for a certain period of time with all the swing pieces 30 positioned at the 5 th shift position (F5) (step ST 5). Next, the operation of step 3 is performed, and the air blowing is performed for a certain period of time while the 1 ST pair of rocker flaps 30a is positioned at the 3 rd shift position (F3) and the 2 nd pair of rocker flaps 30b is positioned at the 5 th shift position (F5) (step ST 6).
After the operation of step 2 is performed (step ST7), the operation of step 1 is performed (step ST 8). This series of operations is repeated until the floor temperature reaches a certain value or more.
In the present embodiment, an experiment was performed in which the temperature in the air-conditioning room in the case of performing the circulation operation was measured in the air-conditioning room in which the ceiling-embedded indoor unit 10 was installed.
Fig. 8A and 8B are explanatory views showing the installation position of the thermocouple for temperature measurement of the ceiling-embedded indoor unit according to the present embodiment, fig. 8A is a view seen from the horizontal direction, and fig. 8B is a view seen from the upper direction. As shown in fig. 8A and 8B, thermocouples 50 are provided at the central portion and the peripheral portion of the ceiling-embedded indoor unit 10. The horizontal interval of each thermocouple 50 is set to 1.5m, and the thermocouples 50 are provided at positions 10cm, 1m, 2m, and 3m from the floor surface in the height direction of the room.
The temperature in the room was adjusted to 20 ℃ and the temperature outside the room was adjusted to 3 ℃, and the cold air was forcibly sent from the outside to the room by the blower. Thus, the temperature of the floor surface in the room is 19 ℃ or higher and 17 ℃ or lower from 1m to the floor surface in the room.
In a state where the set temperature of the remote controller was set to 24 ℃, a circulation operation was performed with the rotational speed of the blower fan set to 470rpm, and the time taken until the indoor temperature was uniform was measured. At this time, when the average temperature of 1m or less from the floor surface reached 21 ℃, it was judged that the temperature was uniform.
Fig. 9 shows the experimental results. From the experimental results, when the operation of the pendulum piece 30 shown in fig. 5A is performed, it takes 4 minutes and 20 seconds, and the average temperature of 1m or less reaches 21 ℃. When the operation of the pendulum piece 30 shown in fig. 5B is performed, it takes 4 minutes and 30 seconds, and the average temperature of 1m or less quickly reaches 21 ℃.
In contrast, when the air blowing is performed with the balance weight 30 fixed at the 5 th gear position facing the lowermost position, it takes 5 minutes and 20 seconds. Further, when the operation of the flaps 30 disclosed in japanese patent No. 5500181 is performed, that is, when the adjacent pair of flaps 30 is positioned at the 5 th position and the other pair of flaps 30 is positioned at the 3 rd position, and the air blowing is performed while gradually shifting the positions of the flaps 30, it takes 6 minutes and 10 seconds, and when the flaps 30 are subjected to the normal swing operation, it takes 6 minutes and 40 seconds.
As can be seen, the operation of the pendulum piece 30 of the present embodiment provides a very good stirring effect for the indoor air.
As described above, in the present embodiment, since the 1 st step, the 2 nd step, and the 3 rd step are sequentially performed, and the 2 nd step of performing air blowing for a certain period of time while all the flaps 30 are positioned at the lowermost position is necessary between the 1 st step and the 3 rd step, the efficiency of stirring the indoor air can be improved, and the air in the air-conditioned room can be rapidly uniformized.
The present embodiment has been described with reference to the drawings, but the present invention is not limited to the above-described embodiment, and can be modified within a range not departing from the gist of the invention.
