(Example 1)
An outline of the examples will be described before the examples of the present disclosure are specifically described. The present embodiment relates to an air conditioning system provided in an apartment house in which a plurality of houses are gathered, for example, an apartment, and which performs air conditioning in the entire building for one house. Generally, a detached house has walls, windows, and doors that are provided in four directions of north, south, east, and west facing the outside, but a house included in an apartment house has walls that are provided in two directions, north and south. , Windows and doors face the outside. Since the time zone of sunshine is different between the space on the south side of the house (hereinafter referred to as "south side space") and the space on the north side of the house (hereinafter referred to as "north side space"), the temperature environment is also different. In addition, since the living room, dining room, etc. are provided in the south space, and the bedroom, etc. are provided in the north space, the time zone of the resident's stay is also different. In order to efficiently carry out air conditioning in the entire building included in an apartment house, such a difference between the south side space and the north side space should be taken into consideration.

In order to cope with this, the air conditioning system according to the present embodiment transports air to the south side space and a transport fan for transporting air to the south side space (hereinafter referred to as "south side transport fan"). A transfer fan for this purpose (hereinafter referred to as "north transfer fan") will be provided separately. In particular, the air conditioning system independently performs control over the south transport fan and control over the north transport fan. Therefore, even if a plurality of rooms are included in the south space, the air conditioning system shares the air transport control for the plurality of rooms. The same applies to the northern space.

Each of the examples described below shows a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps (processes), order of steps, and the like shown in the following examples are merely examples and limit the present disclosure.

A part of the circulating air flows into the air conditioning chamber 180 as circulation RA56. In the air-conditioning chamber 180, the air in which the circulation RA56 and the supply air 60 are mixed is taken into the air-conditioning unit 120 in the entire building. Further, another part of the circulating air is taken into the heat exchange type ventilation fan 104 from the ventilation port 114 as the ventilation RA52. When the first outside air 50a is 100 lubes and the first exhaust 54a is also 100 lubes, the ventilation RA52 is 100 lubes and the supply air 60 is also 100 lubes. If the circulation RA56 is 900 rubes, the total amount of air carried out from the air conditioning unit 120 in the entire building is 1000 rubes. Of the air circulated by the 1000 lube air, 900 lube becomes the circulation RA56 and 100 lube becomes the ventilation RA52.

The air conditioning process executed by the system controller 300 will be described with reference to FIGS. 5 (a) and 5 (c). 5 (a)-(c) are flowcharts showing the air conditioning procedure by the system controller 300. In particular, FIG. 5A is a flowchart showing the air conditioning process, FIG. 5B is a flowchart showing the air conditioning room temperature control process, and FIG. 5C is a flowchart showing the fan air volume setting process. be. As shown in FIG. 5A, the air conditioning process executed by the system controller 300 is mainly composed of the air conditioning room temperature control process S100 and the fan air volume setting process S200, and is executed in this order.

When the user executes the air conditioning process, the system controller 300 executes the air conditioning room temperature control process S100 shown in FIG. 5 (b). In the air-conditioning room temperature control process S100, the system controller 300 acquires the heating / cooling period setting set by the input / output terminal 400 (S101). Here, the heating / cooling period setting is, for example, the cooling period in which the air conditioner 200 is operated (operated) as a cooling device when the temperature rises, and the heating period in the winter when the temperature becomes low and the air conditioner 200 is operated as a heating device. And set. By setting, for example, June to September as the cooling period and December to March as the heating period for the calendar function of the input / output terminal 400, the system controller 300 acquires the setting. can do. Next, the system controller 300 acquires the target temperature set in each of the south side space 10 and the north side space 20 by the input / output terminal 400 via the target temperature acquisition unit 310 (S102).

When the target temperature is acquired, the air conditioning room temperature control unit 312 sets the target temperature of the air conditioning room 180 (air conditioning room target temperature) in the air conditioner 200 (S103). For example, the south side space 10 has an indoor temperature of 28 ° C. and a target temperature of 25 ° C., and the north side space 20 has an indoor temperature of 27 ° C. and a target temperature of 20 ° C. Since the cooling / heating period setting acquired in S101 is the cooling period, that is, the cooling operation, the air-conditioning room temperature control unit 312 controls the air-conditioning room target temperature to a temperature equal to or lower than the lowest temperature among the plurality of target temperatures. Here, a plurality of target temperatures are compared and set to the lowest temperature of 20 ° C. or lower. For example, the target temperature of the air conditioning room is set to 20 ° C. On the other hand, in the heating period, that is, in the heating operation, the air-conditioning room temperature control unit 312 controls the air-conditioning room target temperature to a temperature equal to or higher than the highest temperature among the target temperatures of the south side space 10 and the north side space 20.

Next, the system controller 300 executes the fan air volume setting process S200 shown in FIG. 5 (c). In the fan air volume setting process S200, the system controller 300 acquires the air conditioning room temperature from the air conditioning room temperature sensor 194 (S201). The system controller 300 acquires the indoor temperature of the south side space 10 from the south side temperature sensor 190a, the south side temperature sensor 190b, and the south side temperature sensor 190c, and obtains the indoor temperature of the north side space 10 from the north side temperature sensor 192a, the north side temperature sensor 192b, and the north side temperature sensor 192c to the room of the north side space 20. Acquire the temperature (S202). The system controller 300 acquires the target temperature of the south side space 10 and the target temperature of the north side space 20 from the input / output terminal 400 via the target temperature acquisition unit 310 (S203).

The air-conditioning amount determination unit 314 compares the target temperature with the air-conditioning room temperature and calculates the temperature difference (S204). The blower amount determination unit 314 determines the blower amount of the conveyor fan based on the calculated temperature difference (S205).

The amount of air blown is determined, for example, as follows. When the target temperature of the north side space 20 is 20 ° C. and the temperature of the air-conditioned air-conditioned room 180 is 20 ° C., the amount of air blown by the north side transfer fan 124 corresponding to the north side transfer duct 140 connecting the north side space 20 and the air conditioning room 180. Is the maximum value. Here, the amount of air blown can be the air blown capacity of the transport fan or the operating notch. For example, if it is possible to set the air volume of the transport fan in 10 stages from the air volume "1" to the air volume "10" in order from the one with the smallest air volume, here, the air volume of the north side transport fan 124 is determined to be "10". do. That is, the air volume determining unit 314 lowers the indoor temperature of the north space 20 from 27 ° C., and further blows the maximum amount of air at the same temperature (20 ° C.) in the air conditioning chamber 180 in order to maintain the target temperature of 20 ° C. ,decide.

Further, when the target temperature of the south side space 10 is 25 ° C. and the temperature of the air conditioning room 180 whose air conditioning is controlled is 20 ° C. The target temperature of 10 may be below 25 ° C. Therefore, the blast amount determination unit 314 sets the blast amount of the south side transport fan 122 to, for example, the blast amount “5” which is lower than the maximum value. That is, the air flow rate determining unit 314 responds to the difference between the target temperature and the temperature of the air conditioning chamber, for example, in a space having a large temperature difference (for example, a space having a large temperature difference (for example, the north side space 20: temperature difference 0 ° C.)) with respect to a space having a small temperature difference. The air volume of the transport fan is made larger than that for the south space 10: temperature difference of 5 ° C.).

The above processing is performed for all spaces (S206N → S202 ... → S206Y). When the air flow amount determining unit 314 determines the air flow amounts of the south side transfer fan 122 and the north side transfer fan 124, the total air flow amount is calculated by adding the air flow amount of the south side transfer fan 122 and the air flow amount of the north side transfer fan 124. do. On the other hand, the blast volume determination unit 314 holds as a threshold value "16", which is, for example, 80% of the maximum value "20" of the total blast volume. The blast volume determination unit 314 compares the calculated total blast volume with the threshold value. When the total air volume is equal to or less than the threshold value (Y in S207), the fan air volume control unit 316 controls the south transport fan 122 and the north transport fan 124 according to the air volume determined by the air volume determination unit 314 (Y). S209).

On the other hand, when the total air volume is larger than the threshold value (N in S207), the air volume determination unit 314 determines the air volume of the south transport fan 122 and the north transport fan so that the total air volume is equal to or less than the threshold value. The air volume of 124 is adjusted (S208). At that time, the amount of air blown is adjusted so that the change in the relationship between the amount of air blown by the south-side transport fan 122 and the amount of air blown by the north-side transport fan 124 becomes small. For example, when the air volume of the south transport fan 122 is "10" and the air volume of the north transport fan 124 is "10", the air volume determination unit 314 sets the air volume of the south transport fan 122 to "8". The air volume of the north side transport fan 124 is also changed to "8". The fan air volume control unit 316 controls the south side transfer fan 122 and the north side transfer fan 124 by the air flow amount adjusted by the air flow amount determination unit 314 (S209).

As described above, the diameter of the south side transfer duct 130 is made larger than the diameter of the south side branch transfer duct 134, and the diameter of the north side transfer duct 140 is made larger than the diameter of the north side branch transfer duct 144. Since the south side transport duct 130 and the north side transfer duct 140 are arranged in the ceiling 42, if the diameters of the south side transfer duct 130 and the north side transfer duct 140 become large, there is a possibility that they cannot be arranged in the ceiling 42. In the following, a modified example for dealing with such a situation will be described.

FIG. 6 shows the configuration of the house 1000. The house 1000 is shown in the same manner as in FIG. 1, but instead of the south side transport duct 130, the south side branch chamber 132, and the south side branch transport duct 134 in FIG. 1, from the first south side transport duct 600a collectively referred to as the south side transport duct 600. Includes the 4th south side transport duct 600d. Further, in the house 1000, instead of the north side transport duct 140, the north side branch chamber 142, and the north side branch transport duct 144 in FIG. 1, the first north side transport duct 610a to the fourth north side transport duct 610d collectively referred to as the north side transport duct 610 are used. include.

The first south side transfer duct 600a to the fourth south side transfer duct 600d and the first north side transfer duct 610a to the fourth north side transfer duct 610d are connected to the whole building air conditioning unit 120. The first south side transport duct 600a is connected to the first south side outlet 136a installed in the first Western-style room 12. The second south side transport duct 600b is connected to the second south side outlet 136b installed in the LDK 14, and the third south side transport duct 600c is connected to the third south side outlet 136c installed in the LDK 14. The fourth south side transport duct 600d is connected to the fourth south side outlet 136d installed in the kitchen 16. The south side transport fan 122 of the whole building air conditioning unit 120 transports the air-conditioned air from the first south side transport duct 600a to the first Western-style room 12, LDK 14, and kitchen 16 of the south side space 10 via the fourth south side transport duct 600d. Since the amount of air blown in the south side transfer duct 600 is the same as the amount of air blown in the south side branch transfer duct 134 in FIG. 1, the diameter of the south side transfer duct 600 is the same as the diameter of the south side branch transfer duct 134. Therefore, the diameter of the south side transport duct 600 is smaller than the diameter of the south side transport duct 130 in FIG.

The first north side transport duct 610a is connected to the first north side outlet 146a installed in the second Western-style room 22. The second north side transport duct 610b is connected to the second north side outlet 146b installed at the entrance 26. The third north side transport duct 610c is connected to the third north side outlet 146c installed in the third Western-style room 24, and the fourth north side transport duct 610d is connected to the fourth north side outlet 146d installed in the third Western-style room 24. Will be done. Since the amount of air blown in the north side transfer duct 610 is the same as the amount of air blown in the north side branch transfer duct 144 of FIG. 1, the diameter of the north side transfer duct 610 is the same as the diameter of the north side branch transfer duct 144. Therefore, the diameter of the north side transport duct 610 is smaller than the diameter of the north side transport duct 140 in FIG.

According to this embodiment, since the air in the air conditioning chamber 180 is transported only to the south side space 10 and the north side space 20, it is possible to perform air conditioning suitable for the house 1000 in an apartment house. Further, since the air conditioning suitable for the house 1000 in the apartment house is executed, the air conditioning for the house 1000 in the apartment house can be efficiently executed. Further, since the south transport fan 122 corresponding to only the south space 10 and the north transport fan 124 corresponding to only the north space 20 transport air, the efficiency can be improved while being easy to control. Moreover, since the control is easy and the efficiency is improved, it can be configured at low cost. Further, since the space 10 is divided into the south side space 10 and the north side space 20, the south side space 10 can be controlled according to the high load in summer and the north side space 20 can be controlled according to the high load in winter. Further, since the south side space 10 is controlled according to the high load in the summer and the north side space 20 is controlled according to the high load in the winter, comfort can be realized at low cost.

Further, the average value is calculated from a plurality of sensors such as the south side temperature sensor 190a, the south side temperature sensor 190b, and the south side temperature sensor 190c for the south side space, and the north side temperature sensor 192a, the north side temperature sensor 192b, and the north side temperature sensor 192c for the north side space. ing. The temperature is controlled in the south space and the north space. For this reason, it is possible to realize temperature homogenization and comfort in each space at low cost in an apartment house where the temperature difference is large in the north and south, but the temperature difference is unlikely to occur due to the existence of adjacent houses in the east and west.

Further, since the south side transport duct 130 and the north side transport duct 140 are arranged through the ceiling 42, it is possible to realize piping suitable for the house 1000 in an apartment house. Further, since the exhaust space 30 that does not belong to the south side space 10 and the north side space 20 is separately arranged, the space for exhaust only can be set. Further, since the heat exchange type ventilation fan 104 supplies the heat-exchanged supply air to the air conditioning chamber 180, the heat supply can be efficiently executed. Further, since the heat exchange type ventilation fan 104 can be arranged in the central portion of the house 1000, the lengths of the south side transport duct 130 and the north side transport duct 140 can be shortened. Further, since the temperature of the air conditioning chamber 180 is controlled, it is possible to realize the air conditioning of the house 1000 in the apartment house.

(Example 2)
Next, Example 2 will be described. The second embodiment relates to an air conditioning system provided in an apartment house in which a plurality of houses are gathered, for example, an apartment, and which performs air conditioning in the entire building for one house, as in the first embodiment. In the second embodiment, it is assumed that a gas floor heater is installed in the space on the south side. When the gas floor heater is turned on, the temperature of the south space rises. Therefore, the target temperature can be achieved even if the amount of air blown to the south space is reduced. Further, by reducing the amount of air blown to the south side space, it becomes possible to increase the amount of air blown to the north side space. Hereinafter, the differences from the first embodiment will be mainly described.

FIG. 7 shows the configuration of the house 1000. House 1000 further includes a gas floor heater 500 for the configuration of FIG. The gas type floor heater 500 is installed in the first Western-style room 12 and the LDK 14 in the south side space 10. The gas type floor heater 500 may be installed only in the LDK 14 of the south space 10, or may be installed in the kitchen 16. On the other hand, the gas type floor heater 500 is not installed in the north space 20. In the second embodiment, it is assumed that the air conditioner 200 (not shown) heats the air in the air conditioning chamber 180.

The input / output terminal 400 receives an instruction from the resident to turn on or off the gas type floor heater 500. The input / output terminal 400 transmits a signal (hereinafter, referred to as “instruction signal”) indicating an instruction to turn on or off to the gas type floor heater 500 and the system controller 300. The gas type floor heater 500 has a communication function such as wireless communication, and receives an instruction signal from the system controller 300. The gas type floor heater 500 turns on and off the heating according to the instruction signal.

As described above, the system controller 300 receives the temperature from each of the south side temperature sensor 190a, the south side temperature sensor 190b, the south side temperature sensor 190c, the north side temperature sensor 192a, the north side temperature sensor 192b, the north side temperature sensor 192c, and the air conditioner room temperature sensor 194. do. Further, the system controller 300 receives an instruction signal from the input / output terminal 400. The system controller 300 sets the temperature of the air conditioner 200 based on the received temperature, and transmits the set temperature to the air conditioner 200. Further, the system controller 300 sets the airflow amount of each of the south side transfer fan 122 and the north side transfer fan 124 based on the received temperature, and transmits each of the set air flow amounts to the south side transfer fan 122 and the north side transfer fan 124. do. At that time, the operating status of the gas type floor heater 500 is reflected based on the instruction signal.

FIG. 8 shows the configuration of the system controller 300. The system controller 300 further includes a floor heating operation acquisition unit 320 and a timekeeping unit 322 with respect to the configuration of FIG. The floor heating operation acquisition unit 320 receives an instruction signal from the gas type floor heater 500, and acquires the operation status of the gas type floor heater 500 based on the on or off instruction indicated by the instruction signal. The operating status of the gas floor heater 500 indicates whether the gas floor heater 500 is on or off. The timekeeping unit 322 has a clock function and acquires the current time.

The blast amount determination unit 314 selects an operation for determining the blast amount based on the operation status acquired by the floor heating operation acquisition unit 320 and the time acquired by the timekeeping unit 322. FIG. 9 shows the data structure of the table held in the air volume determination unit 314. As shown in the figure, the operation is defined for the combination of the operating state and the time of the gas type floor heater 500. Here, as an example, the daytime is defined as "7:00 to 19:00" and the nighttime is defined as "19:00 to 7:00 the next day". Daytime and nighttime regulations are not limited to this. The blast volume determination unit 314 identifies whether it is daytime or nighttime based on the time acquired by the timekeeping unit 322.

The blast amount determination unit 314 selects the south side weak blast operation when the operating status of the gas type floor heater 500 indicates ON, that is, when it is acquired that the gas type floor heater 500 is operating. Further, the air flow rate determining unit 314 acquires that the operating status of the gas type floor heater 500 is off and the time is at night, that is, the gas type floor heater 500 is not operating, and is predetermined. Even if it corresponds to the night time, select the south side weak ventilation operation. On the other hand, when the operating status of the gas type floor heater 500 indicates off and the time is daytime, the air flow rate determining unit 314 selects normal operation.

The normal operation is the same operation as that of the first embodiment. Therefore, the air-conditioning volume determination unit 314 executes the fan air-conditioning control process of FIG. 5 (c) after executing the air-conditioning room temperature control process of FIG. 5 (b). On the other hand, in the south side weak air blowing operation, the process of step 205 in the fan air volume control process of FIG. 5C is different from that of the normal operation. The air flow amount determining unit 314 determines the air flow amount of the north side transport fan 124 in the same manner as in the first embodiment.

On the other hand, the air flow amount determining unit 314 determines the air flow amount of the south side transfer fan 122 by reducing the air flow amount of the north side transfer fan 124. Here, the air flow amount determining unit 314 determines the air flow amount of the south side transfer fan 122 in the same manner as in the first embodiment, and then, when the determined air flow amount is equal to or larger than the air flow amount of the north side transfer fan 124, the north side transfer fan 124 The amount of air blown by the south side transport fan 122 may be finally determined by reducing the amount of air blown by the fan. Reducing the amount of air blown by the north-side transport fan 124 corresponds to reducing the amount of air blown by the north-side transport fan 124 by a certain amount, for example, "2". Further, reducing the amount of air blown by the north side transport fan 124 may mean reducing the amount of air blown by the north side transport fan 124 by a certain percentage, for example, "20%". By reducing the amount of air blown by the south side transport fan 122 in this way, it becomes difficult for the total amount of air blown to be larger than the threshold value. As a result, the amount of air blown by the south side transport fan 122 is smaller than the amount of air blown by the north side transport fan 124.

The operation of the air conditioning system with the above configuration will be described. FIG. 10 is a flowchart showing an air conditioning procedure by the system controller 300. If the gas type floor heater 500 is in operation (Y in S500), the air flow rate determining unit 314 selects the south side weak air blow operation (S504). When the gas type floor heater 500 is not operating (N of S500) and not in the daytime (N of S502), the air volume determining unit 314 selects the south side weak air blowing operation (S504). In the daytime (Y in S502), the air flow rate determining unit 314 selects normal operation (S506).

According to this embodiment, when it is acquired that the gas type floor heater 500 is operating, the amount of air blown by the south side transport fan 122 that conveys air to the south side space 10 provided with the gas type floor heater 500. Is smaller than the air volume of the north side transport fan 124, so that air conditioning for the house 1000 in the apartment house can be efficiently performed. Since the amount of energy used by the air conditioner 200 is about 1.5 times higher for heating than for cooling, when the gas floor heater 500 is turned on in the south space 10, the heating by the air conditioner 200 is performed in the north space. By allocating to 20, the load of heating by electricity can be reduced. In addition, since the load of heating by electricity is reduced, energy consumption can be reduced. In addition, since the amount of power supplied to an apartment house is limited for each building, it is possible to cut the peak power consumption during high power consumption. In addition, since the peak power during the time when power consumption is high is cut, it is possible to realize air conditioning in the entire building even with a small contract power. In addition, since floor heating and air conditioning in the entire building are used together, it is possible to achieve a peak cut in winter, which accounts for a large proportion of air conditioning power. Further, since only the north side space 20 is supplemented by the air conditioning in the entire building based on the floor heating with gas, the power consumption can be suppressed. Further, when the floor heating is turned off at night, the set temperature of the non-resident south side space 10 can be lowered to reduce the load, and the energy can be shifted to the resident north side space 20.

The present disclosure has been described above based on the examples. It will be appreciated by those skilled in the art that this embodiment is exemplary and that various variations of each of these components or combinations of processing processes are possible and that such modifications are also within the scope of the present disclosure. ..
