Air conditioning control is performed. Thereby, the facility control apparatus 30 can reduce the power consumption by the air conditioner 20. In the present embodiment, a time zone in which power consumption by the air conditioner 20 is relatively low is set as a first time zone, and a time zone in which power consumption by the air conditioner 20 is relatively high is set as a second time zone.

The weather information acquisition part 301 acquires the weather information for every time of the place where the facility used as a control object is provided from the external device.
Based on the weather information acquired by the weather information acquisition unit 301, the heat input amount estimation unit 302 estimates the amount of heat input to the facility by solar radiation or throughflow.

Next, the operation of the facility control apparatus 30 according to the present embodiment will be described.
FIG. 4 is a flowchart illustrating a method for generating an air conditioning plan by the facility control apparatus 30 according to the first embodiment.
The facility control device 30 generates a daily air conditioning plan before the start of the first time period. The air conditioning plan is a plan related to the load factor of the air conditioner 20 at each time of day.
First, the weather information acquisition unit 301 acquires weather information at each time of day of a place where a facility to be controlled is provided from an external device (step S1). Next, the heat input amount estimation unit 302 estimates the heat input amount of the facility from the weather information (step S2). The amount of heat input is estimated based on the parameters related to the facility housing such as the thermal conductivity of the facility housing and the incident condition of sunlight, and the parameters related to the weather such as the outside air temperature and the amount of solar radiation.

  Next, the reservation data acquisition unit 303 acquires facility use reservation data from the facility management apparatus 10 (step S3). The calorific value estimation unit 304 calculates the number of users in the facility and the number of devices used such as a PC (Personal Computer) from the usage reservation data, and estimates the calorific value based on the number of users (step S4). ). It is preferable that the calorific value estimation unit 304 estimates the calorific value of the heat generating device owned by the user in addition to the heat generated by the user in the facility.

  In addition, the ventilation amount estimation unit 305 calculates the number of users in the facility and the number of people entering and leaving the facility for each time from the use reservation data, and estimates the ventilation amount by the user (step S5). The ventilation amount estimation unit 305, for example, obtains the value obtained by multiplying the number of people entering / leaving the facility by a predetermined coefficient (the amount of ventilation due to entrance / exit of the facility) and the number of users in the facility by the predetermined coefficient. The ventilation amount can be calculated by adding the obtained values (the ventilation amount due to movement between rooms).

  Next, the big data acquisition unit 306 acquires data relating to the facility collected in the past by the facility management apparatus 10 (step S6). Next, the parameter specifying unit 307 performs air conditioning by data mining (frequency pattern extraction or regression analysis) based on the data acquired by the big data acquisition unit 306 and the past control history of the air conditioning device 20 by the operation control unit 311. A parameter having a correlation with the load is specified (step S7). At this time, if there is no parameter that satisfies the predetermined correlation threshold, the parameter specifying unit 307 does not specify the parameter. Next, the parameter specifying unit 307 acquires parameter values that can be used for estimating the air conditioning load at each time of day from the data acquired by the big data acquisition unit 306 (step S8).

  Next, the air conditioning load estimation unit 308 estimates the air conditioning load at each time by substituting the values of heat input, heat generation, ventilation, and parameters specified by the parameter specifying unit 307 at each time into a predetermined function. (Step S9). The air conditioning load estimation unit 308 estimates the air conditioning load q using, for example, the following formula (1) obtained by modifying the energy conservation formula.

ρ represents the air density. Cp _a indicates the air specific heat. T indicates temperature. u represents the ventilation amount estimated by the ventilation amount estimation unit 305. qx indicates the heat input amount estimated by the heat input amount estimation unit 302. Q indicates the heat generation amount estimated by the heat generation amount estimation unit 304. X indicates a parameter specified by the parameter specifying unit 307. [alpha], [beta], [gamma], and [epsilon] are correction coefficients relating to the ventilation amount, the heat input amount, the heat generation amount, and the parameters specified by the parameter specifying unit 307, respectively.

  Next, the heat storage amount determination unit 309 estimates the heat source temperature for each time based on the weather information acquired by the weather information acquisition unit 301 (step S10). This is because when the cooling water that is the heat source of the air conditioner 20 is cooled by the cooling tower, the temperature of the cooling water varies depending on the outside air temperature. Next, the heat storage amount determination unit 309 specifies a load factor for each time at which the COP of the air conditioner 20 is maximized based on the estimated heat source temperature (step S11). The air conditioner 20 has a partial load characteristic in which the COP changes depending on the load factor of the air conditioner 20.

  Next, the heat storage amount determination unit 309 reads out the air conditioning load in the second time zone from the air conditioning loads for each time estimated by the air conditioning load estimation unit 308. And the peak time (time slot | zone (tau) in FIG. 2) when the air-conditioning load when operating the air-conditioning equipment 20 with the load factor in which COP becomes the maximum becomes smaller than the air-conditioning load estimated by step S9 is specified (step S12). Next, the heat storage amount determination unit 309 obtains the sum of the differences between the air conditioning load when the air conditioning device 20 is operated at the load factor at which the COP is maximum and the air conditioning load estimated in step S9 at the specified peak time. The amount of heat to be generated is determined as the amount of heat stored in the heat storage body (step S13).

  Next, the operation control unit 311 calculates the time required for the heat storage amount determination unit 309 to store the heat amount calculated in step S13 in the heat storage body with the load factor estimated in step S11 by the heat storage amount determination unit 309 ( Step S14). The time t required to store the heat storage body is calculated by the following equation (2).

  Qs is the heat storage amount determined by the heat storage amount determination unit 309. qo is the rated output capacity of the air conditioner 20. p is the load factor of the air conditioner 20.

Next, the operation control unit 311 determines whether or not the calculated time is equal to or shorter than the length of the first time zone (step S15).
When the operation control unit 311 determines that the calculated time is equal to or shorter than the length of the first time zone (step S15: YES), the operation control unit 311 stores the heat storage amount as the operation plan for the first time zone. The determination unit 309 determines to perform the heat storage operation of the air conditioner 20 during the time calculated in step S14 with the load factor estimated in step S11 (step S16). Further, the operation control unit 311 determines that the air conditioner 20 is operated at the load factor specified in step S11 during the peak time as the operation plan for the second time zone (step S17). Then, the operation control unit 311 determines to operate the time other than the peak time in the second time zone at the load factor corresponding to the air conditioning load estimated in Step S9 (Step S18).

  On the other hand, when it is determined that the calculated time is longer than the length of the first time zone (step S15: NO), the operation control unit 311 determines the air conditioning equipment in the first time zone from the power consumption of the air conditioning equipment 20 in the peak time. The load factor of the first time zone and the load factor of the peak time are specified such that the value obtained by subtracting the power consumption of 20 is maximized (step S19). For example, the operation control unit 311 calculates the power consumption for each combination of the load factor of the first time zone and the load factor of the peak time, so that the power consumption of the air conditioner 20 at the peak time can be calculated in the first time zone. The combination that maximizes the value obtained by subtracting the power consumption of the air conditioner 20 is specified. The operation control unit 311 can calculate the power consumption E of the air conditioner 20 using the following equation (3).

  Xcop (p) is a COP of the air conditioner 20 when the load factor is p.

  The operation control unit 311 specifies the load factor in the first time zone and the load factor in the peak time so that the maximum value of the power consumption of the air conditioner 20 at the peak time does not exceed the contract power.

  The operation control unit 311 determines, as the operation plan for the first time zone, the heat storage operation of the air conditioner 20 with the load factor determined in step S19 (step S20). Further, the operation control unit 311 determines that the air conditioner 20 is operated at the load factor rate specified in step S19 during the peak time as the operation plan in the second time zone (step S21). Then, the operation control unit 311 determines to operate a time other than the peak time in the second time zone at a load factor corresponding to the air conditioning load estimated in step S9 (step S22).

  Thereby, the facility management apparatus 10 can generate an operation plan that suppresses the peak of the power consumption of the air conditioner 20 and reduces the total power consumption. Next, the facility management apparatus 10 operates the air conditioner 20 based on the generated operation plan. During the operation of the air conditioner 20, the air conditioning load estimation unit 308 estimates the air conditioning load at the current time. This is to cause the operation control unit 311 to correct the operation plan based on the predicted value of the latest air conditioning load.

  In addition, the operation control unit 311 acquires the actual heat source temperature from the heat source temperature acquisition unit 310 in the first time zone and the peak time, and sets the air conditioner 20 at a load factor that maximizes the COP based on the heat source temperature. Make it work. In addition, the operation control part 311 controls a load factor by controlling the rotation speed of a compressor, when the air conditioner 20 is an electric type. The operation control unit 311 can also calculate and control the load factor based on the following equation (4) based on the temperature change rate dT / dt of the heat storage body.

V indicates the volume of the heat storage body. Cp _w indicates the specific heat of the heat storage body.

  When the facility control device 30 finishes operating the air conditioning device 20 for one day, the function correcting unit 312 is a function that the air conditioning load estimating unit 308 uses for estimating the air conditioning load based on the daily operation history by the operation control unit 311. The correction coefficients α, β, γ, and ε in equation (1) are corrected. Thus, the facility management apparatus 10 can control the air conditioning equipment 20 more appropriately by updating the function used for estimating the air conditioning load.

  As described above, according to the present embodiment, the facility management apparatus 10 can refine the estimation of the air conditioning load by utilizing the data of the facility management apparatus 10 that the facility has for management and operation. . As a related technique, there is a technique for estimating an air conditioning load using weather information, but the estimation of the air conditioning load has not been refined using data of the facility management apparatus 10.

As a related technique, there is a technique for creating an operation plan that satisfies a desired heat storage amount at a rated load, but an operation plan has not been formulated in consideration of the partial load characteristics of the air conditioner 20.

  Further, according to the present embodiment, the facility management apparatus 10 estimates the heat generation amount and the ventilation amount based on the number of users, and estimates the air conditioning load based on the heat generation amount and the ventilation amount. As a related technology, there is a technology for estimating the calorific value from the average number of users of the facility, but the calorific value and the ventilation amount have not been estimated from the number of users. The facility management apparatus 10 can estimate the air conditioning load with high accuracy by estimating the ventilation amount in addition to the calorific value.

<< Second Embodiment >>

On the other hand, the facility management apparatus 10 according to the second embodiment controls the air conditioner 20 so that the electricity bill is minimized.

  Generally, the electricity charge for the power system is set to be lower than the daytime electricity charge. Therefore, the facility management apparatus 10 according to the second embodiment causes the air conditioner 20 to perform a heat storage operation in a time zone (first time zone) where the electricity rate is relatively low, and a time zone where the electricity rate is relatively high ( By causing the air conditioner 20 to perform air conditioning control using the heat stored in the second time zone), the electricity charge for air conditioning is suppressed.

By specifying the load factor during peak hours, the air conditioner 20 is controlled so that the electricity bill is minimized.

<< Third Embodiment >>

The light shielding control device is controlled. The shading control device is a device that controls the amount of solar radiation into the facility by adjusting the opening, for example, a blind.

  The operation control unit 311 controls the amount of solar radiation into the facility and the illuminance of the lighting device according to the weather state indicated by the weather information acquired by the weather information acquisition unit 301 in order to ensure the illuminance in the facility. Thereby, the operation control unit 311 can suppress the power consumption of the lighting device. On the other hand, since the amount of heat input increases as the amount of solar radiation into the facility increases, it is necessary to increase the amount of heat removed by the air conditioner 20. Therefore, the operation control unit 311 adjusts the amount of solar radiation into the facility, the illuminance of the lighting device, and the heat removal amount of the air conditioning device 20 so that the power consumption or the electricity bill is minimized.

  As an example, the operation control unit 311 adjusts the amount of solar radiation by controlling the shading control device so that the load factor of the air conditioner 20 is always the load factor that maximizes the COP in the second time zone. Is mentioned.
