JP7515998B2 - Air conditioner and air conditioning control method - Google Patents

Description

The present disclosure relates to an air conditioner and an air conditioning control method.

It is widely known that air conditioners have a function that adjusts the airflow of the air they blow out so that the conditioned air is distributed evenly throughout the space they are conditioned in. This function allows users to feel the same level of comfort regardless of whether they are near the air conditioner or not.

For example, Patent Document 1 describes changing the direction of the Coanda airflow by selecting the attitude of the Coanda blades based on the size of the space to be air-conditioned input by the user.

JP 2013-96639 A

However, while the technology described in Patent Document 1 can be applied to air-conditioned spaces with the same ceiling height, it is difficult for it to be effective in air-conditioned spaces where the ceiling height varies depending on the location.

For this reason, there is a demand for the proposal of new technology that enables appropriate air conditioning even when ceiling heights vary from place to place in areas that are air-conditioned by the same air conditioner.

This disclosure has been made in consideration of the above-mentioned situation, and aims to provide air conditioners etc. that can provide appropriate air conditioning even in areas to be air-conditioned where the ceiling height varies depending on the location.

In order to achieve the above object, the air conditioner according to the present disclosure comprises:
a setting receiving means for receiving, from a user, a setting of ceiling height information relating to a ceiling height for each of a plurality of predetermined sections in an air-conditioned area corresponding to one indoor unit included in the air conditioner;
an air conditioning control means for controlling air conditioning of the air conditioned area based on ceiling height information of each section ,
If any section in the air-conditioned area other than the section in which the indoor unit is installed is an open-air space, the air-conditioning control means adjusts the airflow of the air blown out by the indoor unit during heating operation so as not to direct the wind toward the open-air section .

According to the present disclosure, it is possible to provide appropriate air conditioning even in areas to be air-conditioned where the ceiling height varies depending on the location.

<Functional configuration of the air conditioner 2 and the terminal device 3>
Fig. 5 is a block diagram showing the functional configuration of the air conditioner 2 and the terminal device 3. As shown in Fig. 5, the air conditioner 2 includes a setting reception unit 220, a command information acquisition unit 221, an air conditioning control unit 222, a notification information generation unit 223, and a notification information transmission unit 224. These functional units of the air conditioner 2 are realized by the CPU included in the control circuit 204 of the indoor unit 20 executing the above-mentioned control program.

The terminal device 3 includes a setting information input receiving unit 300, a setting information transmitting unit 301, a command information input receiving unit 302, a command information transmitting unit 303, a notification information acquiring unit 304, and a notification information display unit 305. These functional units of the terminal device 3 are realized by the CPU 33 executing the air conditioning app described above.

In the terminal device 3, the setting information input receiving unit 300 receives input of information related to air conditioning settings (hereinafter referred to as setting information) from the user. In detail, the setting information input receiving unit 300 displays a setting main screen (not shown) on the display 30 and receives a selection from the user as to whether or not to enable the room shape compatible mode. Details of the room shape compatible mode will be described later. If the user selects to enable the room shape compatible mode, the setting information input receiving unit 300 displays a ceiling height information input screen such as that shown in FIG. 6 on the display 30.

The ceiling height information input screen is a screen for accepting input of ceiling height information relating to the ceiling height for each of a number of predefined sections in the area to be air-conditioned by the air conditioner 2 from the user. In this embodiment, as shown in FIG. 6, the area to be air-conditioned is divided into 12 sections, and the setting information input receiving unit 300 accepts input of ceiling height information (ceiling height (m)) for each section from the user. The setting information input receiving unit 300 may display a ceiling height information input screen as shown in FIG. 7 on the display 30, and accept a selection from the user of one of "normal ceiling", "high ceiling" and "open ceiling" as the ceiling height information for each section.

The setting information transmission unit 301 transmits the setting information input by the user (information indicating whether the indoor shape compatible mode is enabled and ceiling height information) to the air conditioner 2.

In the air conditioner 2, the setting reception unit 220 is an example of a setting reception means according to the present disclosure. The setting reception unit 220 receives and accepts the setting information transmitted from the terminal device 3, and stores the accepted setting information in the setting information file 230. The setting information file 230 is a file for storing the setting information, and is stored in an auxiliary storage device provided in the control circuit 204 of the indoor unit 20.

In the terminal device 3, the command information input receiving unit 302 receives input of command information for the air conditioner 3 from the user. The command information includes information instructing the start and stop of various operations such as cooling operation, heating operation, ventilation operation, and dehumidification operation, information indicating whether to enable the wind direction mode and wind shield mode, and information instructing changes to the set temperature, blown air volume, wind direction, etc. The wind direction mode is a mode in which the wind direction is adjusted so that the wind blows on people, and the wind shield mode is a mode in which the wind direction is adjusted so that the wind does not blow on people. Human detection in this mode is performed by analyzing the thermal image data of the room acquired by the thermal image sensor (sensor 203) equipped in the indoor unit 20.

The command information transmission unit 303 transmits the command information input by the user to the air conditioner 2. The command information acquisition unit 221 of the air conditioner 2 receives and acquires the command information transmitted from the terminal device 3, and supplies the acquired specification information to the air conditioning control unit 222.

The air conditioning control unit 222 is an example of an air conditioning control means according to the present disclosure. The air conditioning control unit 222 controls the air conditioning of the air-conditioned area in the house H based on the command information supplied from the command information acquisition unit 221 and the setting information stored in the setting information file 230. When the setting information includes information indicating that the indoor shape compatible mode is enabled and the command information indicates the start of cooling operation or heating operation, the air conditioning control unit 222 starts the cooling operation or heating operation, and determines a control index to be used when estimating the room temperature based on the ceiling height information included in the setting information, and also adjusts the airflow of the air being blown out. Below, the control of the air conditioning control unit 222 in the indoor shape compatible mode is specifically described.

<Control Index>
Conventionally, when an indoor unit is installed in an area with a void, the indoor unit draws in hotter air from the void, so that appropriate air conditioning is difficult to achieve with control using the suction temperature as a control index. Therefore, in the air conditioner 2 of the present disclosure, when the indoor unit 20 is installed in a section with a void (ceiling height: 5100 mm or more), the air conditioning control unit 222 uses both the suction temperature and the floor surface temperature as control indexes to more accurately estimate the room temperature of the area to be air-conditioned (there is no greater deviation from the actual room temperature than when the suction temperature is considered to be the room temperature). The floor surface temperature is obtained by analyzing the thermal image data of the room acquired by the thermal image sensor (sensor 203) equipped in the indoor unit 20.

In addition, if the terminal device 3 is equipped with a temperature sensor that measures air temperature, the air temperature measured by the terminal device 3 may also be added to the control indicators.

When the indoor unit 20 is installed in an area with a normal ceiling height (2400 mm) or high ceiling (2700 mm), the control index shall be the intake temperature as before. However, if the ceiling height is high, even in a high ceiling, the control index shall be the same as for an open ceiling. In this case, the height boundary value is a design matter. The boundary value is determined at the time of design depending on the degree of deviation between the intake temperature and room temperature.

<Control of the fan speed and upper and lower air deflectors of the indoor unit 20 during cooling operation>
During cooling operation, the rotation speed of the fan of the indoor unit 20 (hereinafter referred to as "fan rotation speed") and the angle of the upper and lower air direction plates are adjusted so that the airflow follows the ceiling. During cooling operation, hotter air accumulates near the ceiling due to differences in air density, so the airflow along the ceiling mixes the blown air with the hotter air, eliminating temperature unevenness and making the indoor temperature uniform.

Specifically, for example, as shown in FIG. 8, when the ceiling height of the compartment in which the indoor unit 20 is installed is a normal ceiling height (2400 mm), the angle of the up and down air deflectors is adjusted horizontally to follow the ceiling, as in the conventional method. Also, as shown in FIG. 9, when the ceiling height of the compartment in which the indoor unit 20 is installed is a high ceiling (2700 mm), the angle of the up and down air deflectors is adjusted to an angle (e.g., 30°) that is more upward than the angle of the up and down air deflectors at a normal ceiling height (0° in FIG. 8). Also, the fan rotation speed in this case (in other words, the air volume blown out by the indoor unit 20) is adjusted to a value larger than that in the case of a normal ceiling height (see FIG. 8).

Also, as shown in Figure 10, if the section in which the indoor unit 20 is installed is an open space (5100 mm or more), the angle of the up and down air deflectors is adjusted to an angle (e.g. 60°) that is more upward than the angle of the up and down air deflectors for a high ceiling (30° in Figure 9). Also, the fan rotation speed in this case is adjusted to a value greater than that in the case of a high ceiling (see Figure 9).

In addition, when wind hits a dropped ceiling, it flows downwards, so if the ceiling on the front side as viewed from the indoor unit 20 is high and the ceiling on the back side is low (i.e., if the ceiling on the back side as viewed from the indoor unit 20 is a dropped ceiling), during cooling operation, the air conditioning control unit 222 adjusts the angle of the upper and lower air deflectors to match the lower ceiling height. This makes it possible to prevent cool air from hitting people near the boundary between different ceiling heights directly (see Figure 11).

Figure 12 shows an overview of the control contents of the indoor shape adaptation mode during cooling operation. Note that even if the indoor shape adaptation mode is enabled and command information indicates the start of cooling operation, if the wind direction mode is enabled and there is a person in the air-conditioned area, the air-conditioning control unit 222 adjusts the angle of the upper and lower air deflectors so that the cool air is directed at the person. Also, even after starting cooling operation in which the airflow is adjusted based on the ceiling height information, if the user issues an instruction via the terminal device 3 to change either the blowing air volume or the angle of the upper and lower air deflectors, the air-conditioning control unit 222 changes either the fan rotation speed or the angle of the upper and lower air deflectors in accordance with the instruction.

<Control of fan speed, top/bottom air deflectors, and left/right air deflectors during heating operation>
During heating operation, the angle of the upper and lower air deflectors is adjusted so that the airflow direction becomes downward as the ceiling height increases, and the fan rotation speed is increased.

Specifically, for example, as shown in FIG. 13, when the ceiling height of the compartment in which the indoor unit 20 is installed is a normal ceiling height (2400 mm), the angle of the up and down air deflectors is adjusted to the same angle as in the conventional method (e.g., -65°). Also, as shown in FIG. 14, when the ceiling height of the compartment in which the indoor unit 20 is installed is a high ceiling (2700 mm), the angle of the up and down air deflectors is adjusted to an angle (e.g., -70°) that is more downward than the angle of the up and down air deflectors for a normal ceiling height (-65° in FIG. 13). Also, the fan rotation speed in this case (i.e., the air volume blown out by the indoor unit 20) is adjusted to a value greater than that in the case of a normal ceiling height (see FIG. 13).

Also, as shown in Figure 15, if the section in which the indoor unit 20 is installed is an open space (5100 mm or more), the angle of the vertical airflow direction vanes is adjusted to an angle (e.g. -75°) that is more downward than the angle of the vertical airflow direction vanes for a high ceiling (-70° in Figure 14). Also, the fan rotation speed in this case is adjusted to a value greater than in the case of a high ceiling (see Figure 14).

Furthermore, during heating operation, unless otherwise specified by the user, the airflow direction will avoid the open-ceiling area. Because an open-ceiling has a wide space both above and below, warm air tends to move to higher locations (i.e. the second-floor ceiling) due to density differences. For this reason, directing the airflow toward the open-ceiling when heating the first floor during heating operation is a waste of air conditioning. Therefore, during heating operation, the air conditioning control unit 222 adjusts the angle of the left and right air direction vanes to avoid directing the air toward the open-ceiling area (see Figure 16).

Figure 17 shows an overview of the control contents of the indoor shape response mode during heating operation. Note that even if the indoor shape response mode is enabled and the command information indicates the start of heating operation, if the wind direction mode is enabled and there is a person in an area with an open ceiling, the air conditioning control unit 222 adjusts the angle of the up/down air deflectors and/or the left/right air deflectors so that the warm air is directed at the person (see Figure 18). Also, even after the start of heating operation with the airflow adjusted based on the ceiling height information, if the user instructs the terminal device 3 to change any of the blown air volume, the angle of the up/down air deflectors, and the angle of the left/right air deflectors, the air conditioning control unit 222 changes any of the blown air volume, the angle of the up/down air deflectors, and the angle of the left/right air deflectors according to the instruction.

Returning to FIG. 5, when air conditioning is being performed in the indoor shape compatible mode, the notification information generation unit 223 generates notification information for notifying the user of this fact. The notification information generation unit 223 supplies the generated notification information to the notification information transmission unit 224. The notification information transmission unit 224 transmits the notification information generated by the notification information generation unit 223 to the terminal device 3. The notification information generation unit 223 and the notification information transmission unit 224 are examples of notification means related to the present disclosure.

The notification information acquisition unit 304 of the terminal device 3 receives and acquires the notification information transmitted from the air conditioner 2. The notification information acquisition unit 304 supplies the acquired notification information to the notification information display unit 305. The notification information display unit 305 displays a screen based on the contents of the notification information (hereinafter referred to as the notification screen) on the display 30. Figure 19 shows an example of the notification screen.

Figure 20 is a flowchart showing the steps of the air conditioning control process executed by the air conditioner 2. Each time the air conditioner 2 receives command information transmitted from the terminal device 3, it executes the following air conditioning control process.

The air conditioner 2 determines whether the received command information is an instruction to start cooling operation or heating operation (step S101). If the command information is not an instruction to start cooling operation or heating operation (step S101; NO), the air conditioner 2 executes control according to the command information (step S102). After that, the air conditioner 2 ends the air conditioning control process.

On the other hand, if the command information instructs the start of cooling operation or heating operation (step S101; YES), the air conditioner 2 reads the setting information from the setting information file 230, and by referring to the read setting information, determines whether the indoor shape compatible mode is enabled (step S103).

If the indoor shape adaptation mode is not enabled (step S103; NO), the air conditioner 2 starts cooling or heating operation using the conventional method (step S104). After that, the air conditioner 2 ends the air conditioning control process.

On the other hand, if the indoor shape adaptation mode is enabled (step S103; YES), the air conditioner 2 starts cooling or heating operation, and determines a control index based on the ceiling height information included in the setting information, and adjusts the airflow of the air being blown out (step S105).

After step S105, the air conditioner 2 generates notification information indicating that air conditioning is being performed in the room shape compatible mode, and transmits the generated notification information to the terminal device 3 (step S106). The air conditioner 2 then ends the air conditioning control process.

As described above, according to the air conditioning system 1 of this embodiment, the air conditioner 2 receives ceiling height information settings from the user for each of a number of predefined sections in the area to be air-conditioned, and controls the air conditioning of the area to be air-conditioned based on the ceiling height information of each section. This not only makes it possible to realize appropriate air conditioning according to the ceiling height of the section in which the indoor unit 20 is installed, but also makes it possible to perform appropriate air conditioning even if the ceiling height differs depending on the section.

In addition, if the air conditioning is operating in a mode suited to the room shape, the user will be notified, so they will understand the reason for the air conditioning being different from normal and will be able to feel at ease.

This disclosure is not limited to the above embodiments, and various modifications are of course possible without departing from the spirit and scope of this disclosure.

For example, the main body of the indoor unit 20 may be configured to have an input interface that accepts input of setting information from a user.

In addition, in the above embodiment, the vacant space target area was divided into 12 sections and ceiling height information was accepted from the user, but there is no limit to the number of sections as long as it is two or more sections.

It is also possible to allow the user to input the installation height (m) of the indoor unit 20 via the terminal device 3, and to include information indicating the input installation height in the setting information. In this way, the air conditioner 2 can more precisely adjust the angle of the up/down air direction plate, the angle of the left/right direction plate, and the fan rotation speed according to the distance between the indoor unit 20 and the ceiling, the distance between the indoor unit 20 and the floor, etc., and generate a more appropriate airflow.

In addition, the air conditioner 2 may determine the control index based on the ceiling height information regardless of whether the indoor shape-adaptive mode is enabled or not.

There are also various ways to notify the user. For example, the terminal device 3 may output a sound based on the notification information. The main body of the indoor unit 20 may be configured to have an output interface for notifying the user in a visible manner (light, screen, etc.) or by sound.

The air conditioner 2 may also receive from the user, as setting information, whether or not the indoor unit 20 is under-floor air conditioning, in which the indoor unit 20 is installed under the floor. In the case of under-floor air conditioning, the air conditioner 2 performs air conditioning control as shown in FIG. 21 during both cooling and heating operation.

This disclosure is also applicable to air conditioners that provide air conditioning for buildings other than homes.

The technical ideas relating to each of the above modified examples may be realized individually or in appropriate combination.

Various embodiments and modifications of the present disclosure are possible without departing from the broad spirit and scope of the present disclosure. Furthermore, the above-described embodiments are intended to explain the present disclosure and do not limit the scope of the present disclosure. In other words, the scope of the present disclosure is indicated by the claims, not the embodiments. Various modifications made within the scope of the claims and within the scope of the disclosure equivalent thereto are deemed to be within the scope of the present disclosure.

The present disclosure can be suitably adopted in air conditioners that provide air conditioning for buildings.
