Description

  The disclosed embodiments relate to an air conditioning system.

  Adjacent rooms such as a washroom and a dressing room adjacent to the bathroom are likely to form condensation due to moisture flowing in from the bathroom, which may cause the mirror to become cloudy or mold to form.

  Therefore, in order to suppress the condensation in the adjacent room, a technology has been proposed in which a humidity sensor is installed in the adjacent room and ventilation is started in the adjacent room when the humidity sensor detects that the adjacent room is in a high humidity state ( Patent Document 1).

Japanese Patent No. 3427096

  However, the above-described conventional technology has room for further improvement with respect to suppressing condensation in the adjacent room.

  That is, if ventilation of the adjacent room is started based on the humidity of the adjacent room as in the prior art described above, the ventilation of the adjacent room is started after the humidity of the adjacent room is increased. Cannot be prevented.

  An object of one embodiment is to provide an air conditioning system that can suppress condensation in an adjacent room adjacent to a bathroom.

  An air conditioning system according to an aspect of an embodiment includes a bathroom temperature detection unit that detects a bathroom temperature, an adjacent room air conditioner that has a heating operation mode that heats the adjacent room communicating with the bathroom, and a control that controls the adjacent room air conditioner. And the control unit controls the adjacent room air conditioner based on the detection result of the bathroom temperature detection unit to start the heating operation mode.

  By starting the heating operation mode and increasing the temperature of the adjacent room, the saturated water vapor amount of the adjacent room is increased, and the adjacent room is in a state where condensation is unlikely to occur. Thereby, the dew condensation of an adjacent room can be suppressed. Also, in the bathroom, moisture is generated by hot water filling or shower water discharge, but when hot water filling or shower water discharge starts, the temperature of the bathroom rises before moisture flows from the bathroom to the next room. . Therefore, by starting the heating operation mode based on the detection result by the bathroom temperature detection unit, the heating operation mode is set before the moisture flows into the adjacent room from the bathroom, that is, before the humidity in the adjacent room rises. By starting, it is possible to make the adjacent room difficult to cause condensation. Therefore, according to the air conditioning system which concerns on embodiment, the condensation of an adjacent room can be suppressed more reliably compared with the case where heating operation mode is started based on the humidity of an adjacent room, for example.

  In addition, the control unit determines whether the bath temperature or the bath preparation is in progress based on a change over time in the bathroom temperature detected by the bathroom temperature detection unit, and is in the bathing or bathing preparation. If it is determined, the adjacent room air conditioner is controlled to start the heating operation mode.

  Thereby, heating operation mode can be started in the condition where possibility that moisture will flow in into a next room from a bathroom is high. Moreover, it is possible to suppress the heating operation mode from being started unnecessarily under a situation where the possibility of moisture flowing into the adjacent room from the bathroom is low.

  In addition, it further includes an adjacent room temperature detection unit that detects the temperature of the adjacent room, and the control unit determines that the bath is being prepared or is being prepared for bathing, and the temperature of the adjacent room detected by the adjacent room temperature detection unit. Is equal to or less than a threshold value, the adjacent room air conditioner is controlled to start the heating operation mode.

  Under circumstances where the temperature of the adjacent room is relatively high, the saturated water vapor amount in the adjacent room is relatively high, and thus it may not be necessary to start the heating operation mode. Moreover, if the heating operation is performed under a condition where the temperature of the adjacent room is relatively high, there is a possibility that the user may feel uncomfortable. Therefore, it is possible to suppress the heating operation mode from being started unnecessarily by starting the heating operation mode when the temperature of the adjacent room is equal to or lower than the threshold value.

  The control unit determines that the bath is being prepared or is being prepared for bathing, and the temperature of the adjacent chamber detected by the adjacent chamber temperature detection unit is equal to or lower than a first threshold that is the threshold. Control the adjacent room air conditioner, start the heating operation mode with the first air volume, determine that the bathing or preparing for bathing, and the temperature of the adjacent room detected by the adjacent room temperature detection unit is When it is equal to or lower than a second threshold value that is lower than the first threshold value, the adjacent room air conditioner is controlled to start the heating operation mode with a second air volume that is larger than the first air volume. .

  By starting the heating operation mode with the second air volume, the temperature of the adjacent room can be increased more quickly, so that condensation in the adjacent room can be further suppressed.

  Further, the air conditioner further comprises an adjacent room ventilator having a ventilation operation mode for exhausting the air in the adjacent room to the outside of the adjacent room, the control unit determines that the bath is being prepared or is being prepared for bathing, and the temperature of the adjacent room is determined. When the temperature of the adjacent room detected by the detection unit exceeds the threshold value, the adjacent room ventilation device is controlled to start the ventilation operation mode.

  By performing ventilation operation instead of heating operation when the outside air temperature is relatively high such as in summer, condensation in the adjacent room can be suppressed without causing discomfort to the user.

  Further, the air conditioner further comprises an adjacent room ventilator having a ventilation operation mode for exhausting the air in the adjacent room to the outside of the adjacent room, the control unit determines that the bath is being prepared or is being prepared for bathing, and the temperature of the adjacent room is determined. When the temperature of the adjacent room detected by the detection unit is equal to or lower than the threshold, the adjacent room air conditioner is controlled to start the heating operation mode, and the adjacent room ventilation device is controlled to start the ventilation operation mode. It is characterized by that.

  By performing ventilation operation in addition to heating operation, moisture in the adjacent room can be discharged to the outside of the room, so that condensation in the adjacent room can be further suppressed.

  Moreover, the said control part determines the temperature higher than the temperature of the said bathroom as a target temperature in the said heating operation mode based on the detection result by the said bathroom temperature detection part.

  By setting the target temperature of the adjacent room so that the temperature of the adjacent room becomes higher than the temperature of the bathroom, the saturated water vapor amount of the adjacent room can be made higher than the saturated water vapor amount of the bathroom. Thereby, compared with the case where the target temperature of an adjacent room is set to the temperature lower than the temperature of a bathroom, for example, the condensation of an adjacent room can further be suppressed.

  And a suction port and an air outlet that open toward the bathroom, an air passage that communicates the air inlet and the air outlet, and a fan that generates a flow of air from the air inlet toward the air outlet. A bathroom air conditioner, and the bathroom temperature detector is disposed in the air passage of the bathroom air conditioner.

  By providing a bathroom air conditioner that generates a circulating air flow in the bathroom, the temperature in the bathroom can be equalized earlier than in the case where the bathroom air conditioner is not provided. Therefore, the temperature of the bathroom can be detected more accurately using the bathroom temperature detection unit. Also, by arranging the bathroom temperature detection part in the air passage of the bathroom air conditioner through which the circulation flow passes, for example, compared with the case where the bathroom temperature detection part is arranged in a place where there is little air flow such as the corner of the bathroom Responsiveness to changes in bathroom temperature can be enhanced.

  According to one aspect of the embodiment, it is possible to suppress condensation in the adjacent room adjacent to the bathroom.

FIG. 3 is a diagram illustrating a configuration example of a bathroom air conditioner. FIG. 4 is a flowchart showing the processing procedure of the condensation suppression process.

  Hereinafter, embodiments of an air conditioning system disclosed in the present application will be described in detail with reference to the accompanying drawings. In addition, this invention is not limited by embodiment shown below.

<Outline of air conditioning system>
First, an outline of an air conditioning system according to an embodiment will be described with reference to FIG. Drawing 1 is an outline explanatory view of an air-conditioning system concerning an embodiment.

  As shown in FIG. 1, next to the bathroom 2, an adjacent room 3 such as a washroom, a dressing room, or a washroom is arranged. Since the adjacent room 3 communicates with the adjacent room 3 through a ventilation part 5 such as a louver provided in the bathroom door 4, for example, when bathing or preparation for bathing (for example, hot water filling) is performed in the bathroom 2, the inside of the bathroom 2 Moisture generated in the flow flows into the adjacent chamber 3 through the ventilation part 5. Further, for example, when the user opens the bathroom door 4, moisture may flow from the bathroom 2 to the adjacent room 3. When the moisture in the bathroom 2 flows into the adjacent chamber 3, dew condensation occurs in the adjacent chamber 3, and for example, a mirror in the adjacent chamber 3 may be fogged or mold may be generated in the adjacent chamber 3.

  Therefore, in the air conditioning system 1 according to the embodiment, the temperature of the adjacent chamber 3 is increased when bathing or bathing preparation is started. By increasing the temperature of the adjacent chamber 3, the amount of saturated water vapor in the adjacent chamber 3 is increased, and condensation is less likely to occur in the adjacent chamber 3. Thereby, the dew condensation of the adjacent chamber 3 can be suppressed.

  Specifically, as shown in FIG. 1, the air conditioning system 1 according to the embodiment includes a bathroom temperature detection unit 10, an adjacent room air conditioner 20, and a control unit 30.

  The bathroom temperature detection unit 10 detects the temperature of the bathroom 2. The adjacent room air conditioner 20 has a heating operation mode in which the adjacent room 3 is heated. The control unit 30 controls the adjacent room air conditioner 20.

  Here, in the bathroom 2, moisture is generated by hot water filling or shower water discharge, but when hot water filling or shower water discharge is started, the temperature of the bathroom 2 is increased before the moisture flows into the adjacent room 3 from the bathroom 2. Will rise.

  Therefore, in the air conditioning system 1 according to the embodiment, the adjacent room air conditioner 20 is controlled based on the detection result by the bathroom temperature detection unit 10 to start the heating operation mode. Thereby, before moisture flows into the adjacent room 3 from the bathroom 2, that is, before the humidity of the adjacent room 3 rises, the heating operation mode is started to make the adjacent room 3 less likely to cause condensation. Can do. Therefore, according to the air conditioning system 1 which concerns on embodiment, compared with the case where heating operation mode is started based on the humidity of the adjacent room 3, the condensation of the adjacent room 3 can be suppressed more reliably.

  Thus, according to the air conditioning system 1 which concerns on embodiment, it is possible to suppress the dew condensation of the adjacent room 3. FIG.

<Configuration of air conditioning system>
Next, the configuration of the above-described air conditioning system 1 will be described with reference to FIG. FIG. 2 is a block diagram illustrating a configuration example of the air conditioning system 1.

  As shown in FIG. 2, the air conditioning system 1 includes a bathroom temperature detection unit 10, an adjacent room air conditioner 20, a control unit 30, a bathroom air conditioner 40, and an input device 60.

  The bathroom temperature detection unit 10 detects the temperature of the bathroom 2 and outputs the detection result to the control unit 30. The bathroom temperature detection unit 10 is provided in the bathroom air conditioner 40. The bathroom air conditioner 40 and the control unit 30 of the adjacent room air conditioner 20 are connected by wire or wirelessly, and can communicate bidirectionally. Similarly, the input device 60 and the control unit 30 of the adjacent room air conditioner 20 are connected by wire or wirelessly and can communicate bidirectionally.

  Here, arrangement | positioning of the bathroom temperature detection part 10 is demonstrated with reference to FIG. 3 with the structure of the bathroom air conditioner 40. FIG. FIG. 3 is a diagram illustrating a configuration example of the bathroom air conditioner 40.

  As shown in FIG. 3, the bathroom air conditioner 40 is a so-called built-in type air conditioner embedded in the ceiling 2 </ b> C of the bathroom 2, for example. The bathroom air conditioner 40 includes an inlet 41 and an indoor outlet 42 that open toward the interior of the bathroom 2, an outdoor outlet 43 that opens toward the outside of the bathroom 2, an inlet 41, the indoor outlet 42, and And an air passage 44 communicating with the outdoor air outlet 43. The air passage 44 is, for example, an air passage formed inside the main body of the bathroom air conditioner 40 or a duct provided outside the bathroom air conditioner 40. Moreover, the bathroom air conditioner 40 includes a damper 45 that switches an outflow destination of the air sucked into the air passage 44 from the suction port 41 between the indoor air outlet 42 and the outdoor air outlet 43.

  In addition, the bathroom air conditioner 40 is disposed in the air passage 44 on the upstream side of the damper 45, and the circulation fan 46 and the damper 45 are used when generating an air flow from the suction port 41 toward the indoor outlet 42. A ventilation fan 47 that is disposed in the air passage 44 toward the outdoor air outlet 43 in the downstream air passage 44 and is used when generating a flow of air from the suction port 41 toward the outdoor air outlet 43. .

  The bathroom air conditioner 40 is disposed in the air passage 44 toward the indoor outlet 42 in the air passage 44 on the downstream side of the damper 45, and heats the air flowing in the air passage 44 toward the indoor outlet 42. A heat source 48 such as a heater, and a control unit 49 that controls the damper 45, the circulation fan 46, the ventilation fan 47, and each drive device of the heat source 48 are provided.

  The bathroom air conditioner 40 configured as described above has a “heating operation mode”, a “blower operation mode”, and a “ventilation operation mode”.

  In the heating operation mode, the control unit 49 of the bathroom air conditioner 40 controls the damper 45 to switch the air outlet to the indoor outlet 42. Note that this processing is not necessary when the damper 45 has already been switched to the indoor outlet 42 side.

  In addition, the control unit 49 controls the circulation fan 46 to form an air flow (circulation flow) from the suction port 41 toward the indoor outlet 42 in the air passage 44. Further, the control unit 49 controls the heat source 48 to heat the air flowing from the suction port 41 to the indoor outlet 42. Thereby, the heated air is supplied to the inside of the bathroom 2 from the indoor outlet 42, and the bathroom 2 is heated.

  In the air blowing operation mode, the control unit 49 performs the same control as in the heating operation mode without driving the heat source 48. As a result, air that is not heated by the heat source 48 (for example, air having a temperature equivalent to that of the bathroom 2) is supplied from the indoor outlet 42 into the bathroom 2.

  In the ventilation operation mode, the control unit 49 controls the damper 45 to switch the air outflow destination to the outdoor air outlet 43. Note that this processing is not necessary when the damper 45 has already been switched to the outdoor outlet 43 side.

  In addition, the control unit 49 controls the ventilation fan 47 to form an air flow from the suction port 41 toward the outdoor air outlet 43 in the air passage 44. Thereby, the air in the bathroom 2 is discharged from the inlet 41 to the outdoor outlet 43, and the bathroom 2 is ventilated.

  As shown in FIG. 3, the bathroom temperature detection unit 10 is disposed in the air passage 44 of the bathroom air conditioner 40. Thus, by arranging the bathroom temperature detection unit 10 in the air passage 44 of the bathroom air conditioner 40 through which the circulating flow passes, the bathroom temperature detection unit 10 is placed in a place where there is little air flow, such as a corner of the bathroom 2, for example. Compared with the case where it arrange | positions, the responsiveness with respect to the temperature change of the bathroom 2 can be improved.

  The bathroom temperature detection unit 10 is disposed in the air path 44 on the upstream side of the heat source 48. Accordingly, since the temperature of the air before being heated by the heat source 48 is detected, the bathroom temperature detecting unit 10 is disposed in the air passage 44 on the downstream side of the heat source 48, for example. The temperature of 2 can be detected more accurately.

  Moreover, by providing the bathroom air conditioner 40 which generates the circulation flow of air in the bathroom 2, the temperature in the bathroom 2 can be equalized earlier than in the case where the bathroom air conditioner 40 is not provided. . Therefore, the temperature of the bathroom can be detected more accurately using the bathroom temperature detection unit 10.

  As shown in FIG. 3, an air passage 51 extending from the adjacent chamber 3 is connected to the air passage 44 on the downstream side of the damper 45. As shown in FIG. 2, the air passage 51 communicates with a suction port 52 that opens toward the adjacent chamber 3.

  The bathroom air conditioner 40 can exhaust the air in the adjacent room 3 from the outdoor outlet 43 to the outside of the adjacent room 3 through the suction port 52, the air path 51, and the air path 44 by driving the ventilation fan 47. it can. Thus, the suction port 52, the air passage 51, the air passage 44, the ventilation fan 47, and the outdoor air outlet 43 are an example of an adjacent room ventilation device that exhausts the air in the adjacent room 3 to the outside of the adjacent room 3.

  Here, although the air passage 51 of the adjacent room ventilation device is connected to the air passage 44 of the bathroom air conditioner 40, the air conditioning system 1 may include an adjacent room ventilation device independent of the bathroom air conditioner 40. . In this case, the adjacent room ventilator has a suction port 52 that opens toward the adjacent chamber 3, an air outlet that opens toward the outside of the adjacent chamber 3, an air passage that connects the air inlet 52 and the air outlet, and an air passage What is necessary is just to set it as the structure provided with the fan which is provided and generates the flow of the air which goes to the blower outlet from the suction inlet 52.

  Further, the adjacent room ventilation device may be provided integrally with the adjacent room air conditioner 20. In this case, the air path configuration of the adjacent room air conditioner 20 may be, for example, a configuration in which the air path 51 is excluded from the air path configuration of the bathroom air conditioner 40 illustrated in FIG.

  Returning to FIG. 2, the configuration of the equipment installed in the adjacent room 3 will be described. In the adjacent room 3, an adjacent room air conditioner 20 and an input device 60 are installed.

  The adjacent room air conditioner 20 is a wall-hanging type air conditioner, for example, and is installed on the wall surface of the adjacent room 3. The adjacent room air conditioner 20 is not limited to the wall-mounted type, and may be a so-called built-in type embedded in the ceiling of the adjacent room 3.

  In addition to the control unit 30 described above, the adjacent room air conditioner 20 includes an adjacent room temperature detection unit 21, a drive device 22, a fan 23, a heat source 24, and a storage unit 25. The driving device 22 includes a fan driving device 221 that drives the fan 23 and a heat source driving device 222 that drives the heat source 24, and these are controlled by the control unit 30.

  The adjacent chamber temperature detection unit 21 detects the temperature of the adjacent chamber 3 and outputs the detection result to the control unit 30. The adjacent room temperature detection part 21 is arrange | positioned in the air path of the adjacent room air conditioner 20 similarly to the bathroom temperature detection part 10, for example. Specifically, the adjacent room air conditioner 20 includes a suction port and an air outlet that open toward the adjacent room 3, and an air passage that communicates the suction port and the air outlet. 23 and the heat source 24 are disposed in the air path. In this case, the adjacent room temperature detection unit 21 is preferably arranged in the air path upstream of the heat source 24.

  In addition, the adjacent room temperature detection part 21 does not necessarily need to be arrange | positioned in the air path of the adjacent room air conditioner 20, and may be arrange | positioned outside an air path. Further, the adjacent room temperature detection unit 21 may be arranged in the input device 60.

  The fan 23 is arrange | positioned in the air path of the adjacent room air conditioner 20, and generates the flow of the air which goes to the blower outlet from the suction inlet of the adjacent room air conditioner 20 in the air path of the adjacent room air conditioner 20. The fan 23 is driven by a fan driving device 221. The fan driving device 221 includes a motor.

  The heat source 24 is disposed in the air path of the adjacent room air conditioner 20 and heats the air flowing through the air path of the adjacent room air conditioner 20. The heat source 24 is a heater, for example, and is driven by the heat source driving device 222. The heat source driving device 222 drives the heat source 24 by energizing the heat source 24.

  The storage unit 25 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) and a flash memory (Flash Memory). The storage unit 25 stores various threshold values used for determination processing by the determination unit 31 described later, detection results by the bathroom temperature detection unit 10, and the like.

  The control unit 30 is realized by executing a program stored in the storage unit 25 using a RAM as a work area by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. The control unit 30 is realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

  The control unit 30 includes a determination unit 31 and an operation control unit 32, and realizes or executes the function and action of the dew condensation suppression process described below. Note that the internal configuration of the control unit 30 is not limited to the configuration illustrated in FIG. 2, and may be another configuration as long as it performs a dew condensation suppressing process described later.

  The control unit 30 acquires the detection result of the temperature of the bathroom 2 from the bathroom temperature detection unit 10 and stores it in the storage unit 25 in association with the acquisition date and time.

  The determination unit 31 determines whether or not bathing or bathing preparation is in progress based on the temporal change in the temperature of the bathroom 2 detected by the bathroom temperature detection unit 10.

  Here, “during bathing” indicates a state in which the user is taking a bath or taking a shower in the bathroom 2. In addition, “being prepared for bathing” indicates a state where bathing or shower water discharge is being performed to prepare for bathing, although not bathing. When bathing or bathing preparation is started, the temperature of the bathroom 2 rises. Therefore, by monitoring the temperature of the bathroom 2, it is possible to determine whether bathing or bathing preparation has started.

  For example, the determination unit 31 sequentially takes out a plurality of detection results stored in the storage unit 25 from the latest one every time the detection result by the bathroom temperature detection unit 10 is stored in the storage unit 25 or every predetermined time. The temperature increase rate of the bathroom 2 is calculated using a plurality of detection results. And the determination part 31 determines with it being bathing or preparing for bathing, when the temperature increase rate of the bathroom 2 exceeds the threshold value (determination threshold values, such as bathing) memorize | stored in the memory | storage part 25. FIG.

  The determination threshold for bathing and the like is previously set to a factor other than bathing and preparation for bathing, for example, a rate of temperature increase that can be distinguished from a rate of temperature increase caused by a change in time zone, through experiments and simulations. For example, the determination threshold for bathing or the like is set to 2 ° C./min.

  Moreover, the determination part 31 compares the acquired detection result with the threshold value (mode determination threshold value) memorize | stored in the memory | storage part 25, when the detection result by the adjacent room temperature detection part 21 is acquired. Then, the determination unit 31 instructs the operation control unit 32 to start the first dew condensation suppression operation mode when the acquired detection result (that is, the temperature of the adjacent chamber 3) is equal to or less than the mode determination threshold value. On the other hand, when the acquired detection result exceeds the mode determination threshold value, the determination unit 31 instructs the operation control unit 32 to start the second dew condensation suppression operation mode.

  The mode determination threshold is determined at a temperature that takes into account the season. That is, if the heating operation is performed in summer (assumed temperature of 25 ° C.), the user may feel uncomfortable. Therefore, the mode determination threshold is set to a temperature that does not cause discomfort to the user even when the heating operation is performed. For example, the mode determination threshold is set to 15 ° C. that is assumed as the temperature of spring or autumn.

  The operation control unit 32 controls the operation of the fan 23 by controlling the fan driving device 221. In addition, the operation control unit 32 controls the operation of the heat source 24 by controlling the heat source driving device 222.

  The adjacent room air conditioner 20 has a “heating operation mode” and a “blower operation mode”. In the heating operation mode, the operation control unit 32 controls the fan driving device 221 to drive the fan 23 and controls the heat source driving device 222 to drive the heat source 24. Thereby, the heated air is supplied to the adjacent room 3 from the blower outlet of the adjacent room air conditioner 20, and the adjacent room 3 is heated. In the air blowing operation mode, the operation control unit 32 drives only the fan 23 among the fan 23 and the heat source 24. As a result, air that is not heated by the heat source 24 (for example, air having a temperature equivalent to that of the adjacent room 3) is supplied to the adjacent room 3 from the outlet of the adjacent room air conditioner 20.

  Furthermore, the operation control unit 32 also controls a ventilation fan 47 (see FIG. 3) provided in the bathroom air conditioner 40.

  When the operation control unit 32 is instructed by the determination unit 31 to start the first dew condensation suppression operation mode, the operation control unit 32 controls the fan driving device 221 to drive the fan 23 and also controls the heat source driving device 222 to control the heat source. 24 is driven. That is, the operation control unit 32 starts the heating operation mode. Thereby, the saturated water vapor amount of the adjacent chamber 3 rises, and the adjacent chamber 3 can be brought into a state where it is difficult to condense.

  The target temperature of the adjacent room 3 in the first dew condensation suppression operation mode is set to a temperature higher than the temperature of the bathroom 2. Thus, by setting the target temperature of the adjacent room 3 so that the temperature of the adjacent room 3 becomes higher than the temperature of the bathroom 2, the saturated water vapor amount of the adjacent room 3 can be made higher than the saturated water vapor amount of the bathroom 2. . Thereby, compared with the case where the target temperature of the adjacent room 3 is set to the temperature lower than the temperature of the bathroom 2, the dew condensation of the adjacent room 3 can further be suppressed, for example.

  Further, the target temperature of the adjacent room 3 in the first dew condensation suppression operation mode is set to a temperature obtained by adding a predetermined complementary temperature ΔT to the temperature of the bathroom 2 detected by the bathroom temperature detection unit 10.

  For example, the complementary temperature ΔT is expressed as ΔT = (T2−T1) × α, where T1 is the temperature of the wall surface of the adjacent chamber 3 and T2 is the temperature at the place away from the wall surface (center position of the adjacent chamber 3). Α is a positive number. That is, the complementary temperature is a temperature based on the difference between the temperature of the wall surface of the adjacent chamber 3 and the temperature at a place away from the wall surface.

  Thus, in the first dew condensation suppression operation mode, the target temperature of the adjacent room 3 is set so that the temperature of the wall surface of the adjacent room 3 is higher than the temperature of the bathroom 2. In many cases, a bathroom vanity or a clothes rack is arranged close to the wall surface of the adjacent room 3. Further, particularly in winter, the temperature of the wall surface of the adjacent chamber 3 is lower than the temperature at a location away from the wall surface of the adjacent chamber 3. Therefore, by setting the temperature obtained by adding the supplementary temperature to the temperature of the bathroom 2 as the target temperature of the adjacent room 3 and setting the temperature of the wall surface of the adjacent room 3 to be higher than the temperature of the bathroom 2, Condensation near the wall surface of a certain adjacent room 3 can be more reliably suppressed.

  On the other hand, when the operation control unit 32 is instructed by the determination unit 31 to start the second dew condensation suppression operation mode, the operation control unit 32 controls the ventilation fan 47 of the bathroom air conditioner 40 to control the air in the adjacent room 3 to the adjacent room. 3 to start the ventilation operation mode for exhausting to the outside. By starting the ventilation operation mode, moisture that has flowed into the adjacent room 3 from the bathroom 2 can be exhausted to the outside of the adjacent room 3 together with the air in the adjacent room 3. Thereby, the dew condensation of the adjacent chamber 3 can be suppressed.

  In addition, by performing ventilation operation instead of heating operation when the outside air temperature is relatively high such as in summer, condensation in the adjacent room 3 can be suppressed without causing discomfort to the user.

  As described above, the control unit 30 determines whether or not bathing or bathing preparation is being performed based on a change over time in the temperature of the bathroom 2 detected by the bath temperature detecting unit 10, and bathing or bathing preparation is being performed. When it is determined that there is, the adjacent room air conditioner 20 is controlled to start the heating operation mode.

  Thereby, heating operation mode can be started in the condition where possibility that moisture will flow in into the adjacent room 3 from the bathroom 2 is high. Moreover, it is possible to prevent the heating operation mode from being unnecessarily started under a situation where the possibility of moisture flowing into the adjacent room 3 from the bathroom 2 is low.

  Moreover, the control part 30 determines that it is bathing or preparing for bathing, and controls the adjacent room air conditioner 20 when the temperature of the adjacent room 3 detected by the adjacent room temperature detection part 21 is below a mode determination threshold value. Thus, the heating operation mode is started.

  In a situation where the temperature of the adjacent chamber 3 is relatively high, the saturated water vapor amount in the adjacent chamber 3 is relatively high, and thus it may not be necessary to start the heating operation mode. Moreover, if the heating operation is performed under a condition where the temperature of the adjacent room 3 is relatively high, there is a possibility that the user may feel uncomfortable. Therefore, the heating operation mode can be prevented from being started unnecessarily by starting the heating operation mode when the temperature of the adjacent room 3 is equal to or lower than the mode determination threshold.

  Further, the control unit 30 determines that the bath is being prepared or is being prepared for bathing, and controls the ventilation fan 47 when the temperature of the adjacent chamber 3 detected by the adjacent chamber temperature detection unit 21 exceeds the mode determination threshold. The ventilation operation mode was started. As described above, when the outside air temperature is relatively high such as in summer, the ventilation operation is performed instead of the heating operation, so that dew condensation in the adjacent room 3 can be suppressed without causing discomfort to the user. .

  The input device 60 is, for example, a wall-mounted remote controller, and includes an input unit 61 and a control unit 62. The input unit 61 receives an input operation by the user. The control unit 62 outputs a signal corresponding to the input result to the input unit 61 to the control unit 30 of the adjacent room air conditioner 20. The control unit 30 starts, for example, the heating operation mode or the air blowing operation mode according to the signal output from the control unit 62, or changes the set temperature or the air volume in the heating operation mode. In addition, the control unit 30 can switch on / off of the dew condensation suppression mode in which the dew condensation suppression process is performed according to the signal output from the control unit 62. That is, the user can arbitrarily select whether or not to perform the condensation suppression process.

<Flow chart of condensation suppression process>
Next, the process procedure of the dew condensation suppression process executed in the air conditioning system 1 will be described with reference to FIG. FIG. 4 is a flowchart showing the processing procedure of the condensation suppression process. Note that, as described above, the condensation suppression process is executed in a state where the condensation suppression mode is on.

  As shown in FIG. 4, the control unit 30 acquires the temperature of the bathroom 2 from the bathroom temperature detection unit 10 (step S <b> 101), and determines whether the temperature increase rate of the bathroom 2 has exceeded a determination threshold for bathing or the like ( Step S102).

  In step S102, when the rate of temperature increase in the bathroom 2 does not exceed the determination threshold for bathing or the like (No in step S102), the control unit 30 returns the process to step S101.

  On the other hand, if it is determined in step S102 that the rate of temperature increase in the bathroom 2 has exceeded the determination threshold for bathing or the like (Yes in step S102), the control unit 30 acquires the temperature of the adjacent room 3 from the adjacent room temperature detection unit 21 (step S102). S103), it is determined whether or not the temperature of the adjacent chamber 3 is equal to or lower than the mode determination threshold (step S104).

  When it determines with the temperature of the adjacent room 3 being below a mode determination threshold value in step S104 (step S104, Yes), the control part 30 starts heating operation mode as 1st dew condensation suppression operation mode (step S105).

  On the other hand, when the temperature of the adjacent chamber 3 exceeds the mode determination threshold value in Step S104 (Step S104, No), the control unit 30 starts the ventilation operation mode as the second dew condensation suppression operation mode (Step S106).

  Subsequently, the control unit 30 determines whether or not the termination condition of the first dew condensation suppression operation mode or the second dew condensation suppression operation mode is satisfied (step S107). For example, the control unit 30 determines that the end condition is satisfied when a stop instruction is received from the input device 60, that is, when a stop operation is performed by the user.

  In addition, the control unit 30 may determine that the end condition is satisfied when a predetermined time has elapsed since the start of the first dew condensation suppression operation mode or the second dew condensation suppression operation mode. Moreover, the control part 30 may determine with completion | finish conditions being satisfied, when the temperature of the bathroom 2 detected by the bathroom temperature detection part 10 is less than a threshold value (stop determination threshold value).

  In step S107, when the end condition is not satisfied (step S107, No), the control unit 30 repeats the determination in step S107 until the end condition is satisfied.

  On the other hand, when it determines with completion | finish conditions being satisfied in step S107 (step S107, Yes), the control part 30 complete | finishes the 1st dew condensation suppression operation mode or the 2nd dew condensation suppression operation mode (step S108), and a series This completes the condensation suppression process. When ending the dew condensation suppression process, the control unit 30 may turn off the dew condensation suppression operation mode or may maintain the on state.

<Other embodiments>
In Step S104 of FIG. 4, when the control unit 30 determines that the temperature of the adjacent chamber 3 is lower than the first mode determination threshold, in Step S105, the control unit 30 starts the heating operation mode with the first air volume, When it is determined that the temperature is equal to or lower than the second mode determination threshold value that is lower than the first mode determination threshold value, the heating operation mode may be started with a second air amount that is larger than the first air amount in step S105. Good.

  When the temperature of the adjacent chamber 3 is lower, that is, when the saturated water vapor amount of the adjacent chamber 3 is lower, the temperature of the adjacent chamber 3 is increased more quickly by starting the heating operation mode with the second air volume having a larger air volume. be able to. Accordingly, the condensation in the adjacent chamber 3 can be further suppressed.

  In step S105 of FIG. 4, the control unit 30 controls the fan driving device 221 and the heat source driving device 222 to start the heating operation mode, and controls the ventilation fan 47 to start the ventilation operation mode. It is good.

  In this way, in the first dew condensation suppression operation mode, the ventilation operation is performed in addition to the heating operation, so that the moisture in the adjacent chamber 3 can be discharged to the outside while increasing the saturated water vapor amount in the adjacent chamber 3. 3 dew condensation can be further suppressed.

  Moreover, in step S102 of FIG. 4, it was decided whether the rate of temperature increase of the bathroom 2 exceeded the determination threshold for bathing, etc., but the control unit 30 exceeded the threshold in step S102. It may be determined whether or not.

  In step S104 in FIG. 4, it is determined whether or not the temperature of the adjacent chamber 3 is equal to or lower than the mode determination threshold value. However, the control unit 30 does not necessarily need to perform the determination process in step S104. That is, the control part 30 is good also as starting a 1st dew condensation suppression operation mode, ie, heating operation mode, when it determines with the temperature increase rate of the bathroom 2 exceeding determination thresholds, such as bathing, in step S102.

  In addition, when the control unit 30 determines that bathing or bathing preparation is in progress, the temperature of the bathroom 2 detected by the bathroom temperature detection unit 10 and the temperature of the adjacent room 3 detected by the adjacent room temperature detection unit 21 When the difference exceeds the threshold, the adjacent room air conditioner 20 may be controlled to start the heating operation mode.

  As the temperature difference between the bathroom 2 and the adjacent room 3 is larger, condensation is more likely to occur in the adjacent room 3. Therefore, when the temperature difference between the bathroom 2 and the adjacent room 3 exceeds the threshold value, dew condensation in the adjacent room 3 can be effectively suppressed by starting the heating operation mode.

  As described above, the air conditioning system 1 according to the embodiment includes the bathroom temperature detection unit 10, the adjacent room air conditioner 20, and the control unit 30. The bathroom temperature detection unit 10 detects the temperature of the bathroom 2. The adjacent room air conditioner 20 has a heating operation mode in which the adjacent room 3 communicating with the bathroom 2 is heated. The control unit 30 controls the adjacent room air conditioner 20. Moreover, the control part 30 controls the adjacent room air conditioner 20 based on the detection result by the bathroom temperature detection part 10, and starts heating operation mode.

  Therefore, according to the air conditioning system 1 which concerns on embodiment, the dew condensation of the adjacent room adjacent to the bathroom 2 can be suppressed.

  Further effects and modifications can be easily derived by those skilled in the art. Thus, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications can be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
