Each damper device is an example of a channel opening adjustment device that opens and closes channels of air-conditioned air supplied to each of the plurality of air-conditioned areas.

In the air-conditioning system 1, the damper devices and the outlets are in one-to-one correspondence, so the number of damper devices and the number of outlets are the same. Alternatively, the damper device in the air conditioning system 1 may be configured to open and close passages leading to a plurality of outlets installed in the same air conditioning area.

The indoor unit 10 and the outdoor unit 11 are examples of heat source devices included in the air conditioning system 1 . The indoor unit 10 and the outdoor unit 11 have heat pump cycles. A heat pump cycle has a refrigerant circuit capable of cooling and heating.

The outdoor unit 11 incorporates a compressor 111, a four-way valve, a throttle device, an outdoor heat exchanger, an accumulator, and an electromagnetic valve.

The compressor 111 is an electric compressor that drives a compression mechanism that compresses and discharges refrigerant by energizing the motor. The compressor 111 has a suction section connected to the outflow section of the accumulator, and a discharge section connected to the four-way valve. A pressure sensor that detects the pressure of the refrigerant and outputs it to the system control unit 100 is installed in a pipe that forms a passage that connects the compressor 111 and the four-way valve. The operation of the compressor 111 is controlled by an outdoor unit control section 110 that cooperates with the system control section 100 through information communication.

The four-way valve and the solenoid valve are one of flow path switching devices that can switch the refrigerant flow path between a cooling flow path for performing cooling operation and a heating flow path for performing heating operation. During cooling operation, the indoor heat exchanger functions as a cooling heat exchanger for cooling air, and the outdoor heat exchanger functions as a heat radiating heat exchanger for releasing heat to the outside. During heating operation, the outdoor heat exchanger functions as a heat absorbing heat exchanger that absorbs heat from the air, and the indoor heat exchanger functions as a heating heat exchanger that releases heat to the outside to heat the air. The outdoor heat exchanger is provided with an outdoor fan 112 for ventilating outside air. The outside air blown by the outdoor fan 112 exchanges heat with the refrigerant flowing through the heat exchange core portion of the outdoor heat exchanger. An outside air temperature sensor that detects the outside air temperature and outputs it to the system control unit 100 is installed upstream of the outdoor heat exchanger in the air flow. The operation of the outdoor fan 112 is controlled by an outdoor unit control section 110 that cooperates with the system control section 100 through information communication.

The indoor heat exchanger is provided with an indoor fan 101 that blows the air that has passed through the heat exchange core of the indoor heat exchanger toward the air conditioning area. The air blown by the indoor fan 101 exchanges heat with the refrigerant flowing through the heat exchange core portion of the indoor heat exchanger. A blowout temperature sensor that detects the temperature of the air blown to each blowout port and outputs it to the system control unit 100 is installed downstream of the indoor heat exchanger in the air flow. In the air conditioning system 1, one outlet temperature sensor is installed in each of the plurality of air conditioning areas. The air conditioning system 1 measures the temperature of each air conditioning area with a blowout temperature sensor. The amount of heat supplied per unit time to each air-conditioned area is determined by the temperature and flow rate of the air supplied from each outlet.

The expansion device has a preset degree of opening and is an example of a decompression device that decompresses and expands the high-pressure refrigerant. Refrigerant flowing through the refrigerant circuit flows into the indoor heat exchanger while being decompressed by the expansion device. The throttle device may be constructed by a capillary tube, or may be replaced by an electronic expansion valve whose opening is adjustable.

In the air conditioning system 1, air blown from the indoor unit 10 is supplied to each air conditioning area through each air duct. The air taken in by the indoor unit 10 is indoor air that reaches the suction port of the indoor unit 10 from the suction port 12 installed in the building through the intake duct 12a. The air that flows out from each of the plurality of air-conditioned areas through gaps such as slits provided in the door of the room is collected and sucked into the suction port 12 . In the air conditioning system 1, the ratio of distributing the thermal energy generated by the indoor unit 10 and the outdoor unit 11 to the plurality of outlets is determined by the degree of opening of each damper device with respect to each flow path.

Control devices such as the system control unit 100, the outdoor unit control unit 110, and each damper control unit control the indoor unit 10, the outdoor It controls the operation of the machine 11 and each damper device. The target temperature in the specification may be the temperature determined by the control unit, or may be the set temperature set for each air conditioning area. Each air-conditioned area approaches the set temperature set by the remote control.

In the air conditioning operation control, the air conditioning system 1 maintains the opening degree of the corresponding damper device when the temperature of the air conditioning area is between the target temperature and the thermo-off temperature. In the air conditioning operation control, the air conditioning system 1 closes the opening of the corresponding damper device when the temperature of the air conditioning area satisfies the thermo-off temperature.

In air conditioning operation control, the air conditioning system 1 controls each damper device so that the greater the difference between the target temperature and the current room temperature that has not yet reached the target temperature, the greater the opening degree is maintained or the greater the opening degree. Alternatively, control may be performed by varying the amount of change in the degree of opening so that the degree of opening is increased in increments in order to increase the air volume. In air conditioning operation control, the air conditioning system 1 controls each damper device so that the degree of opening is maintained or reduced as the difference between the current indoor temperature, which has not yet reached the target temperature, and the target temperature is smaller. Alternatively, control may be performed by varying the amount of change in the degree of opening so that the opening is opened in small increments.

A remote controller installed in each air conditioning area has a touch panel including a display device and a touch pad and functions as a user interface. Each remote controller has a display screen portion as an operation display portion that is displayed during operation of the air conditioning system 1 and various air conditioning operation portions. Each remote controller has an air conditioning operation section that allows input of setting of indoor temperature, operation/stop of cooling, operation/stop of heating, operation/stop of dehumidification, etc. in each air conditioning area. The display screen section is controlled to a display state according to a command signal from the system control section 100 .

When operation signals for operation, stop, set temperature, etc. of the indoor unit 10 and detection signals from various sensors are input, the system control unit 100 communicates with the outdoor unit control unit 110, each damper control unit, and the like. The system control unit 100 executes predetermined arithmetic processing in accordance with a command for manual operation and a set temperature for automatic operation, which are set by the air conditioning operation unit. It controls the rotation speed of the blower 112 and the opening of each damper device.

The air conditioning operation unit includes a forced operation operation unit, an automatic operation operation unit, etc. of an air conditioner that can be operated by a user such as a resident or a person in the room. When the user operates the forced operation command operation unit capable of commanding various operations such as cooling, heating, and dehumidification, an operation command signal corresponding to the operation is input to the input unit of the system control unit 100 . The system control unit 100 cooperates with the outdoor unit control unit 110 and each damper control unit to operate air conditioners for performing heating operation or cooling operation. When the user operates the automatic operation operation unit, an automatic operation command signal including the set temperature, air flow rate, etc., set for the target air conditioning area is input to the input unit of the system control unit 100 . The system control unit 100 cooperates with the outdoor unit control unit 110 and each damper control unit to perform heating operation and cooling operation according to the set temperature of each air conditioning area.

The system control unit 100, the outdoor unit control unit 110, the damper control unit 140, or the damper control unit 150 includes an interface unit that communicates with other control units, parts to be controlled, each remote controller, various sensors, etc., an arithmetic processing unit, and a storage unit. and at least.

Furthermore, the elements included in the control system can also be referred to as means for realizing their function only if intentional.

In the case of an air-conditioning system 1 that air-conditions a plurality of air-conditioned areas with one heat source device, normal thermo-off for stopping air conditioning is performed when the thermo-off temperature is satisfied for all air-conditioned areas in which air conditioning operation is provided. Normal thermo-off is an example of operation stop processing included in the air conditioning operation control performed by the air conditioning system 1 . Normal thermo-off can be performed, for example, by stopping the compressor 111, stopping the indoor fan 101, and closing all the damper devices.

The thermo-off temperature, which is the threshold for thermo-off, is set to have a predetermined temperature difference with respect to the set temperature set by operating the air conditioning operation unit or the target temperature determined by the control unit. The air conditioning system 1 sets the thermo-off temperature to a temperature lower than the set temperature or target temperature by a predetermined temperature difference during cooling operation. During cooling operation, when the temperature (room temperature) of the air-conditioned area becomes lower than the set temperature and further reaches the thermo-off temperature, the air-conditioning system 1 executes thermo-off to suppress an overcooling state. The air conditioning system 1 sets the thermo-off temperature to a temperature higher than the set temperature or target temperature by a predetermined temperature difference during heating operation. During the heating operation, when the temperature (room temperature) of the air-conditioned area becomes higher than the set temperature and further reaches the thermo-off temperature, the air-conditioning system 1 turns the thermo-off to suppress an overheating state.

Furthermore, when the air conditioning system 1 provides air conditioning operation to a plurality of air conditioning areas, in addition to the normal thermo-off described above, the following control is performed to prevent the air conditioning areas from being too cold or too warm. . The air-conditioning system 1 performs accelerated air-conditioning control for accelerating the room temperature to reach the thermo-off temperature according to the flowchart shown in FIG. 3 in the first embodiment.

The air conditioning system 1 sequentially executes the processing in each step of the flowchart shown in FIG. Continue to execute the control shown in FIG. That is, the air conditioning system 1 continues the processing of steps S20 and S30 in FIG. 3 during the air conditioning operation. Programs and data related to the control shown in FIG. 3 are stored in the storage unit of the system control unit 100, for example. The time charts shown in FIGS. 4 to 7 show the relationship between the temperature of a representative air-conditioned area and the operation of each air conditioner when the processes of steps S10, S20, and S30 of FIG. 3 are performed in order. .

In a state in which the air conditioning system 1 is powered on, the system control unit 100 performs the above-described air conditioning operation control in step S10 in cooperation with each remote controller corresponding to the air conditioning area to be air-conditioned to operate each air-conditioning area. Supply conditioned air to the area. In the first embodiment, the air-conditioned area to be air-conditioned is the area in which the remote control with the power turned on is installed. Further, the main remote controller 16 may be configured so that an air-conditioned area to be air-conditioned can be set. Alternatively, the air-conditioning areas to be air-conditioned may be set by default to all air-conditioning areas that can be air-conditioned by the air conditioning system 1 .

The system control unit 100 repeatedly executes the determination process of step S10A while continuing the air conditioning operation control set by each remote controller. In step S10A, as described above, it is determined whether or not the temperatures of all the air-conditioned areas meet the thermo-off temperature. When it is determined in step S10A that all the air-conditioned areas have reached the thermo-off temperature, the system control unit 100 performs normal thermo-off in step S10B, and returns to step S10. If all the air-conditioned areas have not reached the thermo-off temperature in step S10A, a NO determination is made, and then determination processing in step S20 is executed.

If the determination in step S10A is NO, system control unit 100 repeats the processes of steps S20 and S30. In step S20, it is detected whether the temperature of each air-conditioned area to be determined satisfies the thermo-off execution condition, and it is determined whether or not the thermo-off execution condition is satisfied for at least one air-conditioned area. In this embodiment, the plurality of air-conditioned areas that are subject to determination in step S20 are all air-conditioned areas to which the air-conditioning system 1 supplies conditioned air. In step S20, when the room temperature of the air-conditioned area becomes lower than the set temperature and reaches the thermo-off temperature during the cooling operation as described above, it is determined that the thermo-off temperature is satisfied and the thermo-off execution condition is established. . Further, during the heating operation, when the room temperature of the air-conditioned area becomes higher than the set temperature and further reaches the thermo-off temperature, it is determined that the thermo-off execution condition is established.

That is, if the thermo-off execution condition is satisfied for one of the plurality of air-conditioned areas to be air-conditioned, but not satisfied for the remaining air-conditioned areas, a YES determination is made in step S20. In step S20, it is needless to say that a YES determination is made even if, for example, one area is not established and the remaining areas are established. Further, if all the air-conditioned areas among the plurality of air-conditioned areas are unsatisfactory, a NO determination is made in step S20.

If the determination in step S20 is NO, the air conditioning area has not yet reached the thermo-off temperature and is neither too cold nor too warm, so the process returns to step S10 to continue the air conditioning operation control. Then, the determination process of step S20 is repeatedly executed while continuing the air conditioning operation control as described above.

If the determination in step S20 is YES, in step S30, system control unit 100 executes acceleration air-conditioning control for quickly approaching a state in which the conditions for executing thermo-off are satisfied in the air-conditioned areas where the conditions for executing thermo-off are not satisfied. The system control unit 100 executes the acceleration air conditioning control process, returns to step S10 again, and continues the air conditioning operation control. The acceleration air-conditioning control in step S30 makes the temperature of the air-conditioned area in which the thermo-off execution condition is not satisfied quickly approach the thermo-off temperature. Among a plurality of air-conditioned areas, an air-conditioned area with a higher air-conditioning load than other areas does not easily reach the thermo-off temperature, so that the indoor unit 10 continues to blow conditioned air, and the other areas are excessively cooled or warmed. do. According to this accelerated air-conditioning control, the air-conditioned area with high air-conditioning load is brought closer to the thermo-off temperature quickly, so that the air-conditioning system 1 quickly stops the air-conditioning and prevents other areas from being too cold or too warm. . Air-conditioning areas with high air-conditioning loads are areas with a large number of heat-generating bodies such as people and machines, areas with a large amount of sunlight coming in from the outside, and areas with a small amount of sunlight coming in from the outside. do.

The system control unit 100 performs thermo-off processing for the air-conditioned area that has reached the thermo-off temperature by controlling the damper device so that the opening degree of the corresponding damper device reaches the controllable lower limit value, thereby substantially air-conditioning the air-conditioned area. stop automatically. As a result, it is possible to prevent the air-conditioned area for which the thermo-off process has been performed from becoming too cold or too warm. The temperature of the air-conditioned area subjected to the thermo-off process gradually returns to a temperature between the thermo-off temperature and the set temperature as the thermo-off state continues.

Next, an example of acceleration air conditioning control will be described with reference to FIGS. 4 to 7. FIG. As an example of accelerated air conditioning control during cooling operation, each air conditioner operates as shown in the time chart of FIG. As shown in FIG. 4, among the plurality of air-conditioned areas, the temperature of the air-conditioned area with a high air-conditioning load and the temperature of the air-conditioned area with a low air-conditioning load compared to this, the temperature of the low air-conditioning load area is turned off first. When the temperature is reached, the thermo-off execution condition is established in the low air conditioning load area. At this time, the thermo-off execution condition has not yet been established in the high air conditioning load area. The air-conditioning system 1 starts accelerating air-conditioning control at the timing indicated by the dashed-dotted line when the temperature of the low air-conditioning load area reaches the thermo-off temperature.

At this time, the air conditioning system 1 maintains the rotational speed of the compressor 111 at a constant value as soon as the acceleration air conditioning control is started. The rotation speed of the compressor 111 is proportional to the refrigerant discharge amount of the compressor 111 or the air conditioning output. In the example shown in FIG. 4, the rotation speed of the compressor 111 is maintained at the lower limit after the acceleration air conditioning control is started. Furthermore, the air conditioning system 1 stops the rotation of the compressor 111 at the timing when the thermo-off execution condition is satisfied for the high air conditioning load area. Thereby, the blast air is sent to the blast duct without being temperature-controlled by the indoor heat exchanger. The air-conditioning system 1 maintains the blowing volume of the indoor fan 101 at a constant value when the acceleration air-conditioning control is started. In the example shown in FIG. 4, the amount of air blown by the indoor fan 101 is maintained at the lower limit after the acceleration air conditioning control is started. As a result, after the acceleration air-conditioning control is started, the amount of air blown from the indoor unit 10 is controlled to the lower limit amount.

As an example of accelerated air-conditioning control, the air-conditioning system 1 controls damper devices corresponding to high air-conditioning load areas in which the conditions for executing thermo-off are not satisfied so that the passage opening degree is increased. With this control, the amount of blown air to the high air conditioning load area increases, and the temperature in this area further decreases and changes to approach the thermo-off temperature. Due to the effect of lowering the temperature due to the increase in the air-conditioning air volume, the high air-conditioning load area where the thermo-off execution condition is not satisfied can be quickly brought to the thermo-off state. When the thermo-off execution condition is satisfied for the high air conditioning load area, the air conditioning system 1 stops increasing the opening of the damper device corresponding to the high air conditioning load area and maintains a constant passage opening. When the opening of the damper device is maintained at a constant passage opening, the temperature in the high air conditioning load area rises and gradually approaches the set temperature.

The air-conditioning system 1 maintains the opening of the damper device corresponding to the low air-conditioning load area where the thermo-off execution condition is satisfied at a constant value as soon as the acceleration air-conditioning control is started. In the example shown in FIG. 4, the opening degree of the damper device is maintained at the lower limit after the acceleration air conditioning control is started. If the opening of the damper device corresponding to the low air-conditioning load area is maintained at the lower limit and the opening of the damper device corresponding to the high air-conditioning load area increases, the amount of air blown to the high air-conditioning load area increases. Decrease the amount of air blown to the load area. As a result, the air conditioning output to the low air conditioning load area is suppressed, so that the low air conditioning load area can be prevented from being too cold. After dropping below the thermo-off temperature in the low air-conditioning load area, the temperature in the high-air-conditioning load area rises around the timing at which the thermo-off execution condition is satisfied, and changes to exceed the thermo-off temperature.

As an example of the acceleration air conditioning control during heating operation, each air conditioner operates as shown in the time chart of FIG. In FIG. 5 as well, the timing indicated by the dashed line corresponds to the start of the acceleration air-conditioning control. As shown in FIG. 5, among the plurality of air-conditioned areas, the temperature of the air-conditioned area with a high air-conditioning load and the temperature of the air-conditioned area with a low air-conditioning load compared to this, the temperature of the low air-conditioning load area is turned off first. When the temperature is reached, the thermo-off execution condition is established in the low air conditioning load area. At this time, the thermo-off execution condition has not yet been established in the high air conditioning load area. During the heating operation, the air conditioning system 1 controls the rotational speed of the compressor 111 and the amount of air blown by the indoor fan 101 in the same manner as during the cooling operation described above.

As an example of acceleration air conditioning control during heating operation, the air conditioning system 1 controls a damper device corresponding to a high air conditioning load area where the thermo-off execution condition is not satisfied so as to increase the passage opening. With this control, the amount of blown air to the high air conditioning load area increases, and the temperature of this area further rises and changes so as to approach the thermo-off temperature. Due to the temperature rise effect due to the increase in the air-conditioning air volume, the high air-conditioning load area in which the thermo-off execution condition is not satisfied can be quickly brought to the thermo-off state. When the thermo-off execution condition is satisfied for the high air-conditioning load area, the air-conditioning system 1 stops increasing the opening of the damper device corresponding to the high air-conditioning load area and maintains a constant passage opening. The temperature of the area decreases and gradually approaches the set temperature.

The air-conditioning system 1 maintains the opening of the damper device corresponding to the low air-conditioning load area at a constant value as soon as the acceleration air-conditioning control is started. In the example shown in FIG. 5, the opening degree of the damper device is maintained at the lower limit after the acceleration air-conditioning control is started. Also in this case, as described above, the amount of air blown to the high air conditioning load area increases, and the amount of air blown to the low air conditioning load area decreases. As a result, the air conditioning output to the low air conditioning load area is suppressed, so that the low air conditioning load area can be prevented from being overheated. After exceeding the thermo-off temperature in the low air-conditioning load area, the temperature in the high-air-conditioning load area begins to decrease around the timing at which the thermo-off execution condition is satisfied, and changes to fall below the thermo-off temperature.

In accelerated air-conditioning control, the air-conditioning system 1 maintains the opening of the corresponding damper device when the temperature of the air-conditioned area satisfies the thermo-off temperature and is within a predetermined temperature range. In the air conditioning operation control, the air conditioning system 1 closes the opening of the corresponding damper device when the temperature of the air conditioned area satisfies the thermo off temperature and deviates from the thermo off temperature so as not to be included in the predetermined temperature range.

In the acceleration air conditioning control, the air conditioning system 1 maintains the opening degree of each damper device or reduces the opening degree as the difference between the target temperature and the current indoor temperature, which has already reached the target temperature but has not reached the thermo-off temperature, increases. , or may be controlled by varying the amount of change in the opening so that the opening is opened in small increments. The air conditioning system 1 maintains or increases the opening of each damper device in accelerated air conditioning control as the difference between the target temperature and the current indoor temperature, which has already reached the target temperature but has not reached the thermo-off temperature, is smaller. , or may be controlled by varying the amount of change in the degree of opening so that the degree of opening is increased in increments.

Accelerated air-conditioning control during cooling operation is performed, for example, by controlling the rotational speed of compressor 111 or the amount of air blown by indoor fan 101 as shown in the time chart of FIG. In FIG. 6 as well, the timing indicated by the dashed line corresponds to the start of the acceleration air-conditioning control. As shown in FIG. 6, the temperature change in the low air conditioning load area and the temperature change in the high air conditioning load area are the same as the temperature changes shown in FIG.

The air conditioning system 1 controls to increase the rotation speed of the compressor 111 as an example of acceleration air conditioning control during cooling operation. Accelerated air-conditioning control by increasing the output of the compressor lowers the temperature of the air blown to the high air-conditioning load area, and the temperature of this area further lowers and changes to approach the thermo-off temperature. Due to the temperature lowering effect due to the increase in the cooling output, it is possible to quickly bring the high air conditioning load area in which the thermo-off execution condition is not satisfied to the thermo-off state. When the thermo-off execution condition is established for the high air conditioning load area, the air conditioning system 1 stops the operation of the compressor 111 to greatly reduce the cooling output to the building. When the cooling output is greatly reduced, the temperature in the high air conditioning load area rises and gradually approaches the set temperature. On the other hand, the temperature in the low air-conditioning load area where the thermo-off execution condition is satisfied temporarily falls below the thermo-off temperature due to an increase in the cooling output, and then rises and exceeds the thermo-off temperature due to the shutdown of the compressor 111. Change. Since the air conditioning output to the low air conditioning load area is suppressed in this way, it is possible to prevent the low air conditioning load area from being too cold.

As an example of accelerated air conditioning control during cooling operation, the air conditioning system 1 may be controlled to increase the amount of air blown by the indoor fan 101 . Accelerated air conditioning control based on this air flow increase increases the cooling air flow to the high air conditioning load area, and the temperature of this area further drops and changes to approach the thermo-off temperature. Due to the temperature lowering effect due to the increase in the cooling air volume, it is possible to quickly bring the high air conditioning load area in which the thermo-off execution condition is not satisfied to the thermo-off state. When the thermo-off execution condition is established for the high air conditioning load area, the air conditioning system 1 controls the air blowing volume of the indoor fan 101 to the lower limit value to greatly reduce the cooling air volume into the building. When the cooling air volume is greatly reduced, the temperature in the high air conditioning load area rises and gradually approaches the set temperature. On the other hand, the temperature in the low air-conditioning load area where the thermo-off execution condition is satisfied temporarily drops below the thermo-off temperature due to an increase in the cooling air volume, and then rises as the air volume of the indoor fan 101 is controlled to the lower limit. In turn, it changes to exceed the thermo-off temperature. Since the amount of air-conditioned air to the low air-conditioning load area is suppressed in this way, it is possible to prevent the low air-conditioning load area from being too cold.

Accelerated air conditioning control during heating operation is performed, for example, by controlling the rotational speed of compressor 111 or the amount of air blown by indoor fan 101 as shown in the time chart of FIG. In FIG. 7 as well, the timing indicated by the dashed line corresponds to the start of the acceleration air-conditioning control. As shown in FIG. 7, the temperature change in the low air conditioning load area and the temperature change in the high air conditioning load area are the same as the temperature changes shown in FIG. During the heating operation, the air conditioning system 1 controls the rotation speed of the compressor 111 and the amount of air blown by the indoor fan 101 in the same manner as during the cooling operation shown in FIG.

The air-conditioning system 1 performs control to increase the rotational speed of the compressor 111 as an example of acceleration air-conditioning control during heating operation. Accelerated air-conditioning control by increasing the output of the compressor raises the temperature of the air blown to the high air-conditioning load area, and the temperature of this area further rises and changes so as to approach the thermo-off temperature. Due to the temperature rise effect due to the increase in the heating output, it is possible to quickly bring the high air conditioning load area in which the thermo-off execution condition is not satisfied to the thermo-off state. When the thermo-off execution condition is satisfied for the high air conditioning load area, the air conditioning system 1 stops the operation of the compressor 111 to greatly reduce the heating output to the building. When the heating output is significantly reduced, the temperature in the high air conditioning load area decreases and gradually approaches the set temperature. On the other hand, the temperature in the low air-conditioning load area where the thermo-off execution condition is satisfied temporarily exceeds the thermo-off temperature due to an increase in the heating output, and then begins to decrease due to the shutdown of the compressor 111 so that it falls below the thermo-off temperature. Change. Since the air-conditioning output to the low air-conditioning load area is suppressed in this way, it is possible to prevent the low air-conditioning load area from being overheated.

As an example of accelerated air conditioning control during heating operation, the air conditioning system 1 may be controlled to increase the amount of air blown by the indoor fan 101 . Accelerated air-conditioning control based on this increase in the amount of air flow increases the amount of heating air to the high air-conditioning load area, and the temperature in this area further rises and changes so as to approach the thermo-off temperature. Due to the temperature rise effect due to the increase in the amount of air for heating, the high air conditioning load area in which the thermo-off execution condition is not satisfied can be quickly brought to the thermo-off state. When the thermo-off execution condition is satisfied for the high air conditioning load area, the air conditioning system 1 controls the air blowing volume of the indoor fan 101 to the lower limit value to greatly reduce the heating air volume into the building. When the heating air volume is greatly reduced, the temperature in the high air conditioning load area decreases and gradually approaches the set temperature. On the other hand, the temperature in the low air-conditioning load area where the thermo-off execution condition is satisfied temporarily exceeds the thermo-off temperature due to an increase in the amount of heating air, and then decreases as the amount of air blown by the indoor fan 101 is controlled to the lower limit. In turn, it changes to fall below the thermo-off temperature. Since the amount of air-conditioned air to the low air-conditioning load area is suppressed in this way, it is possible to prevent the low air-conditioning load area from being overheated.

Actions and effects provided by the air conditioning system 1 of the first embodiment will be described. The air conditioning system 1 supplies conditioned air to each of a plurality of air conditioned areas. The air conditioning system 1 performs accelerated air conditioning control to increase the speed at which the other air conditioning areas reach the thermo-off temperature when at least one of the air conditioning areas satisfies the thermo-off temperature.

According to this air-conditioning system 1, when at least one air-conditioned area out of a plurality of air-conditioned areas satisfies the thermo-off temperature, the other air-conditioned areas that do not satisfy the thermo-off temperature are subjected to accelerated air-conditioning control. This accelerated air-conditioning control makes it possible to bring the other air-conditioned areas, which do not meet the thermo-off temperature, closer to the temperature that satisfies the thermo-off temperature at an early stage. The air-conditioning system 1 contributes to suppressing overcooling and overheating of the plurality of air-conditioned areas. The air-conditioning system 1 can quickly solve the situation where people in the air-conditioned area lose their comfort.

The air-conditioning system 1 includes a channel opening adjustment device that opens and closes channels of conditioned air supplied to each of a plurality of air-conditioned areas. The air-conditioning system 1 performs accelerated air-conditioning control by controlling the channel opening degree adjustment device so that the opening degree of the channel increases. According to this configuration, by controlling the degree of opening of the flow path to be large by the flow path opening adjustment device, the amount of air blown to the downstream air-conditioning area is increased, and a greater air-conditioning capacity can be supplied. In this way, the accelerated air conditioning control of passage opening adjustment can save energy, and the temperature of the air conditioned area can be quickly brought to the thermo-off temperature.

Accelerated air-conditioning control includes control of the flow path opening adjustment device and control of the compressor 111 so as to further increase the refrigerant discharge amount. According to this configuration, by controlling the compressor 111 so as to further increase the refrigerant discharge amount, it is possible to increase the air volume of strongly conditioned air and blow it to the downstream air-conditioned area. With this conditioned air, the temperature of the conditioned area can be brought to the thermo-off temperature more quickly.

The accelerated air conditioning control includes controlling the flow path opening adjusting device and controlling the indoor blower 101 so as to increase the blowing volume of the conditioned air. According to this configuration, since the primary air volume blown from the indoor unit 10 is increased, more conditioned air can be blown to the downstream air-conditioned area. Also with this configuration, the temperature of the air-conditioned area can be brought to the thermo-off temperature more quickly.

The air conditioning system 1 includes a compressor 111 that discharges a refrigerant that circulates through a heat pump cycle. The air conditioning system 1 controls the compressor 111 so as to increase the amount of refrigerant discharged to increase the air conditioning output, thereby performing accelerated air conditioning control. According to this configuration, by increasing the heat absorbing action and heat releasing action of the refrigerant in the indoor heat exchanger, a greater air conditioning capacity can be supplied to the downstream air conditioning area. In this way, the temperature of the air-conditioned area can be quickly brought to the thermo-off temperature by controlling the air-conditioning output in the heat pump cycle to be enhanced.

Accelerated air conditioning control includes controlling the indoor fan 101 so as to increase the blowing amount of conditioned air in addition to increasing the refrigerant discharge amount of the compressor 111 . According to this configuration, the heat absorption action and heat dissipation action of the refrigerant in the indoor heat exchanger are enhanced, and the primary air volume blown from the indoor unit 10 is increased. More air can be blown to the downstream air conditioning area. Therefore, the temperature of the air-conditioned area can be quickly brought to the thermo-off temperature.

The air-conditioning system 1 performs accelerated air-conditioning control by controlling the indoor blower 101 so as to increase the amount of conditioned air blown. According to this configuration, by controlling the amount of air blown by the indoor fan 101 to be large, the amount of air blown to the downstream air-conditioned area is increased, and a greater air-conditioning capacity can be supplied. you can take it with you.

(Second embodiment)
In the second embodiment, another control executed by the air conditioning system 1 will be described with reference to FIG. The flowchart of FIG. 8 differs from the flowchart described with reference to FIG. 3 in the first embodiment in steps S30A and S40. Contents different from the first embodiment will be described below.

The system control unit 100 repeatedly executes the processing of steps S20, S30A, and S40 while continuing the air conditioning operation control set by each remote controller. If the determination in step S20 is YES, system control unit 100 executes thermo-off processing to stop air conditioning in step S30A. In step S30A, for example, a thermo-off process is performed by executing indoor fan 101 stop processing, damper device lower limit opening degree processing, damper device closing processing, and compressor 111 stop processing. The air-conditioning system 1 stops air-conditioning for all air-conditioned areas by performing a thermo-off process when a thermo-off execution condition is satisfied in at least one air-conditioned area. This control can prevent the air-conditioned area from being too cold or too warm.

After executing the thermo-off process, the system control unit 100 sets the opening degree of the damper device to a predetermined start position in step S40, and sets the opening degree at the start of the next air conditioning operation. Then, the process returns to step S10 and waits until the next air conditioning operation. In step S40, the opening degree of the damper device is set as follows. In step S40, the damper device corresponding to the air-conditioned area for which the thermo-off execution condition is satisfied in step S20 is set to the opening degree of the lower limit value or the opening degree that closes the passage. As a result, the next air-conditioning operation can be started from a state in which the air-conditioning output is small and the air-conditioning is difficult to work. In step S40, the damper device corresponding to the air-conditioned area in which the thermo-off execution condition is not satisfied in step S20 is set to the opening of the upper limit value or the opening of the passage. As a result, the next air-conditioning operation can be started from a state where the air-conditioning output is large and the air-conditioning is easy to work.

According to the second embodiment, the air-conditioning system 1 performs thermo-off processing to stop air-conditioning for all air-conditioned areas when at least one air-conditioned area satisfies the thermo-off temperature exists among a plurality of air-conditioned areas. do.

According to this air-conditioning system, when at least one air-conditioned area out of a plurality of air-conditioned areas satisfies the thermo-off temperature, all air-conditioned areas are subjected to the thermo-off process. By this process, the air conditioning is prevented from spreading to each air conditioning area any more, and the temperature control is quickly stopped. This air-conditioning system 1 can prevent the air-conditioned area from being too cold or too warm due to continued air-conditioning, and can quickly avoid the loss of comfort for people in the air-conditioned area.

After executing the thermo-off process, the air-conditioning system 1 sets the damper device corresponding to the air-conditioned area for which the thermo-off execution condition is satisfied to the opening degree of the lower limit value or the opening degree that closes the passage. According to this configuration, the next air-conditioning operation can be started from a state in which air-conditioning output is low and air-conditioning is difficult to work.

After performing the thermo-off process, the air-conditioning system 1 sets the damper device corresponding to the air-conditioned area that does not satisfy the thermo-off temperature to the opening of the upper limit value or the opening of the flow path. According to this configuration, the next air conditioning operation can be started from a state in which the air conditioning output is high and the air conditioning is easy to work. You can contribute to reducing the difference.

(Third embodiment)
In the third embodiment, another control executed by the air conditioning system 1 will be described with reference to FIG. 9 . The flowchart of FIG. 9 differs from the flowchart described in the second embodiment in that step S21 is executed after step S20, and that acceleration air-conditioning control processing is executed when the determination in step S21 is NO. do. Contents that differ from the above-described embodiment will be described below.

The system control unit 100 repeatedly executes the determination process of step S20 and the determination process of step S21 while continuing the air conditioning operation control set by each remote controller. If the determination in step S20 is YES, the system control unit 100 determines in step S21 whether or not the opening of the damper device is at the lower limit. Further, in step S21, it may be determined whether or not the opening degree of the damper device is such that the flow path is closed.

If the opening degree of the damper device is not the lower limit value or the flow path is not closed in step S21, the same acceleration air conditioning control as in the first embodiment is executed in step S30, and the process returns to step S10. to continue air conditioning operation control. If the opening degree of the damper device is at the lower limit or the flow path is closed in step S21, the same thermo-off process as in the first embodiment is executed in step S30A. Further, in the same manner as in the second embodiment, the start opening degree processing of the damper device is performed in step S40, and the process returns to step S10 to wait until the next air conditioning operation.

If the determination in step S21 is YES, it means that the amount of air blown to each air conditioning area is small or almost zero. In this state, the thermo-off execution condition is satisfied in at least one of the plurality of air-conditioned areas even though the air is gradually blown into the air-conditioned areas. In such a state, the degree of overcooling or overwarming has progressed considerably, so the air conditioning can be immediately stopped to suppress the deterioration of comfort at an early stage.

Further, in step S21, the opening degrees of the damper devices corresponding to all the air-conditioned areas that are subject to determination in step S20 are determined. In this case, even though the opening of all the damper devices is closed or close to that, the air conditioning is sufficiently effective even though the air volume is small. It is possible to suppress overcooling and overheating of all air-conditioned areas.

Further, in step S21, it is assumed that the opening degree is determined for the damper device corresponding to the air-conditioned area determined that the thermo-off execution condition is not satisfied. In this case, it takes time to reach the thermo-off temperature even if accelerated air-conditioning control is applied to the unsatisfactory area. Therefore, by executing the thermo-off process in step S30A rather than the acceleration air-conditioning control, it is possible to early suppress overcooling or overheating of all the air-conditioned areas.

In the air-conditioning system 1 of the third embodiment, when even one air-conditioned area that satisfies the thermo-off temperature exists among the plurality of air-conditioned areas, the opening degree of the passage opening degree adjusting device corresponding to all the air-conditioned areas is set to the lower limit. Acceleration air conditioning control is not performed when the value or flow path is closed. In this case, the air conditioning system 1 performs thermo-off processing to stop air conditioning for all air-conditioned areas. According to this configuration, the air conditioning is sufficiently effective even though there is almost no air flow. By executing thermo-off processing without executing acceleration air-conditioning control in such a state, air-conditioning can be immediately stopped, so that it is possible to quickly escape from overcooling or overheating of all air-conditioned areas.

(Fourth embodiment)
In the fourth embodiment, another control executed by the air conditioning system 1 will be described with reference to FIG. 10 . The flowchart of FIG. 10 differs from the flowchart described with reference to FIG. 3 of the first embodiment in that steps S31, S32, and S40 are executed after step S30. Further, step S32 is the same processing as step S30A of the second embodiment. Contents different from the first embodiment and the second embodiment will be described below.

The system control unit 100 repeatedly executes the determination process of step S20 and the determination process of step S31 while continuing the air conditioning operation control set by each remote controller.

After the acceleration air-conditioning control is executed in step S30, it is determined in step S31 whether or not there is an area where the thermo-off execution condition is still not satisfied after a predetermined time has elapsed since the acceleration air-conditioning control was executed. That is, in step S31, it is determined whether or not there is an air-conditioned area that has not yet reached the thermo-off temperature even though the acceleration air-conditioning control has been continued for a predetermined period of time.

If all areas have reached the thermo-off temperature in step S31, normal thermo-off is performed in step S10B, and the process returns to step S10 to continue air conditioning operation control. If it is determined in step S31 that there is an area for which the thermo-off execution condition is still not satisfied, the same thermo-off processing as in step S30A of the second embodiment is performed in step S32. Then, in the same way as in the second embodiment, the start opening degree processing of the damper device is performed in step S40, and the process returns to step S10 to wait until the next air conditioning operation.

If the determination in step S31 is YES, it means that all the air-conditioned areas have not yet reached the thermo-off temperature even though the accelerated air-conditioning control has been continued for the predetermined time. Even if the accelerated air-conditioning control is continued, it will take more time to reach the thermo-off temperature, so the air-conditioning is immediately stopped in step S30A. By this process, it can be avoided that the degree of overcooling or overheating progresses further.

The air-conditioning system 1 of the fourth embodiment performs thermo-off processing to stop air conditioning for all air-conditioned areas if there is an air-conditioned area that does not meet the thermo-off temperature after a predetermined time has elapsed since the acceleration air-conditioning control was performed. to implement. According to this configuration, the air conditioning is forcibly stopped when all the air conditioning areas do not enter the thermo-off state even if the accelerated air conditioning control is performed for a predetermined time. As a result, it is possible to reduce the execution time of the acceleration air-conditioning control, save energy, and quickly escape from overcooling or overheating of all the air-conditioned areas.

(Fifth embodiment)
A fifth embodiment will be described with reference to FIGS. 11 and 12. FIG. As shown in FIG. 11, the air-conditioning system 1 of the fifth embodiment includes a target area operation unit that can set the air-conditioning area to be determined in step S20A of FIG. 12 by a human operation such as a user. The air-conditioned area excluded from the determination target in step S20A by operating the target area operation unit is recognized as an exclusion area in the determination processing in step S11. Since the exclusion area is an area that can be set by the user or the like in this manner, the area desired to be excluded from the targets of the acceleration air-conditioning control or the like can be set according to the preferences of the user or the like. The user, etc. can select, as excluded areas, for example, an air-conditioned area that is used infrequently, an area that has a low air-conditioning load compared to other areas, an area that has a high air-conditioning load compared to other areas, and an area that does not require air conditioning. Can be set.

The main remote controller 16 includes a target area operation section 16b that can set whether or not at least the first area 21 is to be determined in step S20A. In addition to the first area 21, the target area operation unit 16b may be configured to be able to set other remaining areas. In this configuration, the target area operation unit 16b determines not only the first area 21 but also at least one of the second area 22, the third area 23, the fourth area 24, and the fifth area 25. It is an operation unit that can set whether or not to The system control unit 100 is configured to receive a setting signal regarding a setting area according to the operation of the target area operation unit 16b.

The individual remote controller 161 includes a target area operation section 161b that can set whether or not the second area 22 is to be determined in step S20A. The system control unit 100 is configured to receive a setting signal related to the setting area according to the operation of the target area operation unit 161b. The individual remote controller 162 includes a target area operation section 162b that can set whether or not the third area 23 is to be determined in step S20A. The system control unit 100 is configured to receive a setting signal related to the setting area according to the operation of the target area operation unit 162b. The individual remote controller 163 includes a target area operation section 163b that can set whether or not the fourth area 24 is to be determined in step S20A. The system control unit 100 is configured to receive a setting signal regarding a setting area according to the operation of the target area operation unit 163b. The individual remote controller 164 includes a target area operation section 164b that can set whether or not the fifth area 25 is to be determined in step S20A. The system control unit 100 is configured to receive a setting signal related to the setting area according to the operation of the target area operation unit 164b.

The flowchart of FIG. 12 differs from the flowchart described in the second embodiment in that the determination process of step S11 is executed after step S10. The system control unit 100 repeatedly executes the determination processing of steps S11, S20, and S20A while continuing the air conditioning operation control set by each remote controller.

The system control unit 100 determines whether or not there is an exclusion area in step S11. When the exclusion area is not set in step S11, the determination process of step S20 is performed, and when YES determination is performed in step S20, step S30A and step S40 are performed in order.

If an exclusion area is set in step S11, it is detected in step S20A whether the temperature of each set air-conditioned area satisfies a thermo-off execution condition, and the thermo-off execution condition is established for at least one air-conditioned area. Determine whether or not In step S20A, determination processing is performed in the same manner as in step S20 of the first embodiment.

If the thermo-off execution condition is met for any one of the set areas that are not excluded, but not for the remaining air-conditioned areas, a YES determination is made in step S20A. Further, if the condition is not established for all the air-conditioned areas among the set areas, a NO determination is made in step S20A.

If the determination in step S20A is NO, all the set areas have not yet reached the thermo-off temperature and are neither too cold nor too warm, so the process returns to step S10 to continue the air conditioning operation control. If the determination in step S20A is YES, the system control unit 100 sequentially executes steps S30A and S40, returns to step S10, and waits until the next air conditioning operation.

The air-conditioning system 1 of the fifth embodiment includes a target area operation unit capable of setting an air-conditioned area for determining whether or not the thermo-off temperature is satisfied. In step S20A, the air conditioning system 1 determines whether there is at least one air conditioning area that satisfies the thermo-off temperature among the plurality of air conditioning areas set by operating the target area operation unit.

According to this configuration, it is possible to set an exclusion area based on the judgment of the user, for example, if the area is not an air-conditioned area that requires air-conditioning capacity. As a result, it is possible to provide the air conditioning system 1 that can perform accelerated air conditioning control that is suitable for the user's preference and ease of use. In addition, in areas with a high air conditioning load, or areas with a large amount of solar radiation and heat dissipation even when there are few people or no people, it is difficult to reach the thermostat temperature even if accelerated air conditioning control is performed, which is a factor that lengthens the time for accelerated air conditioning control. can be. By setting such an area as an exclusion area, the air-conditioning system 1 of the fifth embodiment can reduce the time required for accelerating air-conditioning control and provide air-conditioning operation control that quickly brings the vehicle to a highly comfortable state.

(Sixth embodiment)
A sixth embodiment will be described with reference to FIGS. 13 and 14. FIG. As shown in FIG. 13, the air-conditioning system 1 of the sixth embodiment has a function of automatically detecting an air-conditioned area in which a person is present, which is to be determined in step S20B of FIG. It has An air-conditioned area in which the presence of a person cannot be detected by the occupancy detection device 17 is an area with a low air-conditioning load because there is no heating element such as a person, and is recognized as an absent area in the determination process of step S11A. For example, a human sensor, a heat ray sensor, a thermography camera, or the like can be used as the presence detection device 17 . The system control unit 100 is configured to receive a signal indicating the detection result of the presence detection device 17 .

The flowchart of FIG. 14 differs from the flowchart described in the fifth embodiment in that steps S11 and S20A of FIG. 12 are replaced with steps S11A and S20B. The system control unit 100 repeatedly executes the determination processing of steps S11A, S20, and S20B while continuing the air conditioning operation control set by each remote controller.

In step S11A, the system control unit 100 determines whether or not there is an unoccupied area among the plurality of air-conditioned areas, based on the detection result of the presence detection device 17. FIG. If there is no absence area in step S11A, the determination process of step S20 is executed, and if the determination is YES in step S20, step S30A and step S40 are executed in order.

If there is an absent area in step S11A, it is detected in step S20B whether the temperature of the occupied areas excluding the absent area satisfies the thermo-off execution condition, and whether the thermo-off execution condition is satisfied for at least one occupied area. determine whether or not In step S20B, determination processing is performed in the same manner as in step S20 of the first embodiment.

If the thermo-off execution condition is satisfied for one of the areas in which a person is present and not satisfied for the remaining areas, a determination of YES is made in step S20B. Further, if the condition is not established for all the areas in the room, a NO determination is made in step S20B.

If the determination in step S20B is NO, all areas in the room have not yet reached the thermo-off temperature and are neither too cold nor too warm, so the process returns to step S10 to continue the air conditioning operation control. If the determination in step S20B is YES, system control unit 100 sequentially executes step S30A and step S40, returns to step S10, and waits until the next air conditioning operation.

The air-conditioning system 1 of the sixth embodiment includes a room presence detector 17 capable of detecting an air-conditioned area in which a person is present. The air-conditioning system 1 determines whether or not there is at least one air-conditioned area that satisfies the thermo-off temperature among a plurality of air-conditioned areas in which the occupancy detection device 17 has detected the presence of a person. According to this configuration, an air-conditioned area that does not require air-conditioning capacity due to the absence of people can be set as an exclusion area by automatic operation instead of relying on human judgment. As a result, it is possible to provide the air conditioning system 1 that can perform accelerated air conditioning control or the like suitable for the fact of the presence of people without the need for manual setting.

(Seventh embodiment)
In the seventh embodiment, other controls executed by the air conditioning system 1 will be described with reference to FIG. 15 for the differences from the first embodiment. The flowchart of FIG. 15 differs from the flowchart described with reference to FIG. 3 of the first embodiment in that the determination process of step S22 is executed after step S20.

If the determination is YES in step S20, acceleration air conditioning control is not started until a predetermined waiting time elapses in step S22, and after the predetermined waiting time elapses, acceleration air conditioning control is executed in step S30. That is, if the determination in step S20 is YES, the acceleration air conditioning control is not immediately executed, but if such a state continues for a while, the acceleration air conditioning control is executed to increase the air conditioning output of the indoor unit 10. The thermo-off temperature is reached early by raising the temperature or increasing the air flow rate.

The air-conditioning system 1 of the seventh embodiment starts accelerated air-conditioning control after the standby time has passed since one of the plurality of air-conditioned areas has reached the thermo-off temperature. According to this, a YES determination is made due to a temporary change in room temperature due to a temporary change in the amount of solar radiation from the outside or a temporary change in the number of people in the room, and the acceleration air conditioning control is immediately started. You can prevent it from being lost. In addition, when there is only a small difference in the air conditioning loads between multiple air conditioning areas and there is only a short time left until the temperature reaches the thermo-off temperature, it is possible to suppress overcooling or overheating by performing normal thermooff processing without executing acceleration air conditioning control. .

(Eighth embodiment)
In the eighth embodiment, regarding other controls executed by the air conditioning system 1, contents different from the second embodiment will be described with reference to FIG. The flowchart of FIG. 16 differs from the flowchart described with reference to FIG. 8 of the second embodiment in that the determination process of step S23 is executed after step S20.

If the determination in step S20 is YES, the thermo-off process is not started until a predetermined waiting time elapses in step S23, and the thermo-off process in step S30A is executed after the elapse of the predetermined waiting time. That is, if the determination in step S20 is YES, the thermo-off process is not immediately executed, but if such a state continues for a while, the thermo-off process can be executed to prevent overcooling or overheating. .

The air-conditioning system 1 of the seventh embodiment starts the thermo-off process after a predetermined standby time has passed since at least one air-conditioned area satisfying the thermo-off temperature exists among the plurality of air-conditioned areas. According to this, a YES determination is made due to a temporary change in the room temperature due to a temporary change in the amount of solar radiation from the outside or a temporary change in the number of people sitting in the room, and the thermo-off process is started immediately. You can prevent it from slipping.

(Ninth embodiment)
In the ninth embodiment, regarding other controls executed by the air conditioning system 1, contents different from the first embodiment will be described with reference to FIG. The flowchart of FIG. 17 differs from the flowchart described with reference to FIG. 3 of the first embodiment in that acceleration air-conditioning control is divided into two stages of processing in steps S30B and S30C.

If the determination in step S20 is YES, system control unit 100 controls indoor fan 101 to increase the blowing output as one of the acceleration air conditioning controls in step S30B. As a result, the amount of air supplied to each air-conditioned area increases, which contributes to early reaching the thermo-off temperature.

The process of step S30B continues until it is determined in step S22 that the predetermined control time has elapsed. When the temperature of the air-conditioned area reaches the thermo-off temperature before the predetermined control time elapses, the normal thermo-off processing described above is executed, so the processing of step S30 is stopped and the process returns to step S10. . If the thermo-off temperature is not reached even after step S30B is continued for a predetermined control time, processing for increasing the air conditioning output is executed in step S30C, and the process returns to step S10 to continue air conditioning operation control. The system control unit 100 executes a process of increasing the output of the compressor 111 so as to increase the refrigerant discharge amount in step S30C, for example. Further, the air conditioning system 1 of the ninth embodiment may be configured such that the order of steps S30B and S30C in the flowchart of FIG. 17 is changed. Even with this configuration, the air conditioning can be strengthened step by step when the output of the accelerated air conditioning control is not sufficient.

According to the ninth embodiment, by stepwise increasing the air flow rate and increasing the air conditioning output, the air conditioning can be strengthened when the output of the accelerated air conditioning control is not sufficient. suppression can be achieved.
