The ceiling cooling means 31 includes a radiant cooler provided on the ceiling of the target room 3, and a cooling unit 32 (see FIG. 2) provided on the ceiling and a cooling device 33 (see FIG. 1) that cools the cooling unit 32. It has. The cooling unit 32 is made of a ceiling material that constitutes the ceiling surface of the target room 3, and the cooling device 33 is made of an air conditioner installed behind the ceiling. That is, the ceiling cooling means 31 drives a compressor and a fan (not shown) included in the cooling device 33 to cool the cooling unit 32 by flowing cool air through the ceiling space above the cooling unit 32, and the cooling unit 32 cools the cooling unit 32. Radiation cooling of the target room 3 is performed by radiation. Further, the operation level of the ceiling cooling means 31 can be switched between three levels of “high”, “medium”, and “low”, and the switching of the operation level adjusts the output of the compressor and the fan. It is done by doing.

  When the new air conditioning equipment 2 such as the ceiling cooling means 31 enters the system, the control means 8 acquires contribution data for the thermal environment of the new air conditioning equipment 2 as shown in FIG. ing. The numbers in parentheses in FIG. 5 indicate the order in which communication is performed, and the numbers in parentheses in FIG. 1 correspond to this.

  Specifically, the new air conditioning equipment 2 entering the existing air conditioning system notifies the control unit 30 of the control means 8 that the control means 8 has entered the system when the new air conditioning equipment 2 enters the system. It has a function. On the other hand, the control unit 30 has a data request function for requesting contribution data transmission to the new air conditioning device 2 when receiving a notification from the new air conditioning device 2. The new air conditioning equipment 2 is set with contribution data set in advance for each equipment. Further, the new air conditioning device 2 has a data transmission function for transmitting its own contribution data from the new air conditioning device 2 to the control unit 30 when the control unit 30 requests contribution data transmission.

  That is, when a new air conditioning device 2 enters the system, the notification function of the new air conditioning device 2 notifies the control unit 30 that the new air conditioning device 2 has entered the system (1). Subsequently, the data request function of the control unit 30 requests the contribution data transmission to the new air conditioning device 2 (2), and in response to this, the new air conditioning device 2 receives the control unit 30 by the data transmission function. The contribution data is transmitted to (3). As a result, the control unit 30 acquires contribution data for the thermal environment of the new air conditioning device 2.

  The contribution degree data includes contribution degree data for at least one parameter among the parameters for calculating the comfort degree composed of the PMV value. That is, the contribution degree data is data relating to the contribution degree to at least one of room temperature, humidity, radiation temperature, wind speed, amount of clothes, and amount of activity, which is information of the target room 3 that is a thermal environment, and the degree of comfort. Is correlated.

  The contribution degree data includes, for example, data indicating the correspondence relationship between the information on the thermal environment and the contribution degree of the new air conditioning equipment 2 correlated therewith.

  6A and 6B are graphs showing contribution data of the ceiling cooling means 31. FIG. The contribution degree data of the ceiling cooling means 31 is data relating to the contribution degree to the room temperature of the target room 3 (FIG. 6A) and the contribution degree to the wall surface temperature of the target room 3. The contribution is a temperature change per unit time (deg / min), and this value changes according to the temperature of the target chamber 3 as shown in FIG. For this reason, the contribution degree data of the ceiling cooling means 31 is composed of a data table indicating the relationship between each contribution degree and the room temperature of the target room 3 correlated with each contribution degree.

  The contribution data of the existing air conditioning equipment 1 is set in the control means 8 in advance. For example, in the temperature adjusting means 4 (air conditioner), as with the ceiling cooling means 31, the contribution to the room temperature of the target room 3 shown in FIG. 7A and the wall surface of the target room 3 shown in FIG. Data relating to the contribution to temperature is set as contribution data.

  The control unit 30 after entering the new air-conditioning equipment 2 controls the existing air-conditioning equipment 1 and the new air-conditioning equipment 2 when the operation command is received (4) by operating the operation means 7 as shown in FIG. (5). This control is performed based on the detection result of the comfort level detection means, the contribution data of the existing air conditioning equipment 1, and the acquired contribution data of the new air conditioning equipment 2.

  Specifically, the control unit 30 detects the comfort level by the comfort level detection means every predetermined time, and based on the detected comfort level and contribution data of each of the existing air conditioning equipment 1 and the new air conditioning equipment 2, The operation level and operation time of each of the existing air conditioning device 1 and the new air conditioning device 2 are determined. Based on this determination result, the operation of each of the existing air conditioning equipment 1 and the new air conditioning equipment 2 is controlled.

  FIG. 9 is a graph showing changes over time in the room temperature and the wall surface temperature of the target room 3 when the existing air conditioning equipment 1 and the new air conditioning equipment 2 are cooperatively controlled based on the detected comfort level and the contribution degree data. is there. In this example, the control unit 30 receives the detection result by the comfort level detection means, and sets the temperature adjustment means 4 (air conditioner) that is the existing air conditioning equipment 1 to the level “low” and the ceiling that is the new air conditioning equipment 2. The cooling means 31 is simultaneously operated at a level “medium” for 2.5 minutes. As a result, the room temperature and wall surface temperature of the target room 3 reach the target temperature 2.5 minutes after the comfort level is detected.

  In the example of FIG. 9, the existing air conditioning equipment 1 other than the temperature adjusting means 4 is not operated. In the example of FIG. 9, after both the room temperature and the wall surface temperature have reached the target temperature, the operation of all the existing air conditioning equipment 1 and new air conditioning equipment 2 is stopped until the detected comfort level is out of the predetermined range. The control of the existing air conditioning equipment 1 and the new air conditioning equipment 2 is determined when the predetermined range is not reached. However, the present invention is not limited to this. For example, after both the room temperature and the wall surface temperature reach the target temperature, the air blowing means 6 may be operated until the detected comfort level is out of a predetermined range.

  For reference, FIG. 8 shows the room temperature and wall surface of the target room 3 when only the temperature control means 4 is operated when the thermal environment of the target room 3 is the same as the example of FIG. 9 before the ceiling cooling means 31 enters. It is a graph which shows the time change of temperature. In the example of FIG. 8, the control unit 30 receives the detection result by the comfort level detection means and operates the temperature adjustment means 4 at the level “low” for 5 minutes. As a result, the room temperature and wall surface temperature of the target room 3 reach the target temperature 5 minutes after the comfort level is detected.

  That is, in the air conditioning system after the entry of the new air conditioning device 2 according to the present embodiment, when the existing air conditioning device 1 and the new air conditioning device 2 are linked and controlled, the contribution data of the new air conditioning device 2 is used. Yes. For this reason, as can be seen from the comparison between FIG. 8 and FIG. 9, it is possible to appropriately control the operation of the existing air-conditioning device 1 and the new air-conditioning device 2 to quickly bring the target room 3 into the target thermal environment. .

  Even when the new air conditioning device 2 is operated alone, the new air conditioning device 2 is appropriately controlled using the acquired contribution data.

表１は、新規空調用機器２である天井冷房手段３１を検知快適度及び取得した天井冷房手段３１の寄与度データに基づいて単独で運転したときの、経過時間、壁面温度、室温、及び天井冷房手段３１の運転レベルを示している。なお、この例では、目標室温が２７℃に設定され、目標壁面温度が２３℃に設定されている。

Table 1 shows the elapsed time, wall surface temperature, room temperature, and ceiling when the ceiling cooling means 31 that is the new air conditioning device 2 is operated alone based on the detected comfort level and the acquired contribution data of the ceiling cooling means 31. The operation level of the cooling means 31 is shown. In this example, the target room temperature is set to 27 ° C., and the target wall surface temperature is set to 23 ° C.

  As can be seen from the fact that the strong operation is switched to the weak operation after 4 minutes in Table 1, since the contribution data of the ceiling cooling means 31 can be grasped in this embodiment, the vicinity of the target temperature before the operation is performed. Can be predicted, and thus efficient operation can be realized.

  In the air conditioning system of the present embodiment described above, when a new air conditioning device 2 different from the existing air conditioning device 1 newly enters the system, the control means 8 for controlling the existing air conditioning device 1 is for new air conditioning. The contribution data for the thermal environment of the device 2 is acquired. Then, the control means 8 controls the existing air conditioning equipment 1 and the new air conditioning equipment 2 in cooperation using the acquired contribution data. For this reason, the existing air-conditioning device 1 and the new air-conditioning device 2 can be appropriately operated and controlled, and the target room 3 can be brought into the target thermal environment quickly or efficiently.

  In the present embodiment, the contribution degree data acquired by the control unit 8 correlates with the comfort level, and the control unit 8 uses the detection result of the comfort level detection unit and the acquired contribution degree data for existing air conditioning. The device 1 and the new air conditioning device 2 are linked and controlled. For this reason, the existing air conditioning device 1 and the new air conditioning device 2 can be appropriately controlled using the contribution degree data so that the detected comfort level becomes the target comfort level.

(Second embodiment)
Next, a second embodiment different from the above will be described. In addition, about the same structure as 1st embodiment, the same number is provided and the overlapping description is abbreviate | omitted.

  The control means 8 of the present embodiment has a learning function for rewriting contribution data acquired from the new air conditioning device 2 to new contribution data based on the actual use of the new air conditioning device 2.

  FIG. 10 is a graph showing contribution data with respect to room temperature of the ceiling cooling means 31 which is the new air conditioning device 2 in relation to the room temperature and the contribution degree. The solid line in FIG. 2 indicates initial contribution data (contribution data set in the ceiling cooling means 31) at the operation level “high” acquired when the control unit 30 enters the ceiling cooling means 31. A point P in FIG. 2 indicates the actual measurement contribution (−0.6 deg / min) at the operation level “high” of the ceiling cooling means 31 measured at an arbitrary room temperature (25 ° C.). Further, the broken line in FIG. 2 indicates the corrected contribution data at the operation level “high” of the ceiling cooling means 31 rewritten based on the measured contribution degree of the ceiling cooling means 31 at an arbitrary room temperature.

  In the example of FIG. 10, the difference (−0.2 deg / min) between the actual measurement contribution (−0.6 deg / min) and the contribution (−0.4 deg / min) corresponding to the actual measurement contribution in the initial contribution data. ) Multiplied by a coefficient a (0.25: a satisfies 0 <a <1) as a correction value (−0.05 deg / min). Then, initial contribution data represented by a relational expression of y = −0.08x + 1.6 (y: contribution (deg / min), x: room temperature (° C.)) is represented by a relation of y = −0.08x + 1.55. The contribution data shown in the formula is rewritten. The reason why the coefficient a is multiplied in the above is to suppress variations caused by a change in the outside air temperature, a change in the wall surface temperature, the door of the target chamber 3 being opened, and the like. The actual measurement contribution may be data acquired when the ceiling cooling unit 31 is operated alone, or data acquired when another existing air conditioning device 1 is operated simultaneously with the ceiling cooling unit 31. Data obtained by subtracting the contribution degree of the existing air-conditioning device 1 may be used.

  The contribution data rewritten as described above is used as new contribution data thereafter, and the cooperative control between the existing air conditioning device 1 and the new air conditioning device 2 is performed using the latest contribution data.

  As described above, in the present embodiment, the contribution data is rewritten to new contribution data based on the usage record of the new air conditioning equipment 2, and thereafter, the existing air conditioning equipment 1 and the new air conditioning are used using the new contribution data. Device 2 is cooperatively controlled. For this reason, the contribution degree data used for the cooperative control of the existing air conditioning equipment 1 and the new air conditioning equipment 2 can be set to a value according to the actual construction situation according to the actual use of the new air conditioning equipment 2. The existing air conditioning device 1 and the new air conditioning device 2 can be controlled more appropriately.

  Further, the contribution degree data of the ceiling cooling means 31 of the present embodiment includes data indicating a correspondence relationship between the information on the thermal environment and the contribution degree of the new air conditioning device 2 correlated therewith. And when the control means 8 acquires the information of arbitrary thermal environment and the contribution degree of the ceiling cooling means 31 corresponding to this as a usage record of the ceiling cooling means 31, contribution data based on this acquired use record To be new contribution data. For this reason, the entire contribution degree data composed of data indicating the correspondence relationship between the information on the thermal environment and the contribution degree of the new air conditioning equipment 2 correlated therewith is quickly changed to a value corresponding to the actual construction situation. The existing air conditioning device 1 and the new air conditioning device 2 can be appropriately controlled.

  The contribution data may be sequentially rewritten in the same manner as described above every time data on the usage record of the new air conditioning equipment 2 is acquired, or may be rewritten only at the time of setting such as initial use. It may be.

  Moreover, in each said embodiment, although it was set as the air conditioning system into which the new air conditioning apparatus 2 was newly entered into the several existing air conditioning apparatus 1, the system before entering the new air conditioning apparatus 2 is one for existing air conditioning The apparatus 1 may be provided. In each of the above embodiments, the comfort level is set as the PMV value, but other comfort indexes such as ET (Effective Temperature: effective temperature) may be detected as the comfort level. In addition, each of the existing air-conditioning device 1 and the new air-conditioning device 2 in each embodiment is not limited to the above-described one, and may be another air-conditioning device.
