Description

  The present invention relates to an air conditioning control device and a program.

  In indoor spaces such as offices, the air conditioner is manually controlled to adjust the indoor environment to an environment appropriate for humans, or the indoor environment is used as equipment (or machines) such as office automation (OA) equipment. Adjust to an appropriate environment.

  On the other hand, the presence / absence of a person in the room is detected using a human sensor, a card reader held by the person, etc., and the air conditioner is controlled according to the detection result of whether the room is manned or unmanned. Thus, a technique for adjusting the indoor temperature or humidity with an air conditioning control device has been proposed (for example, Patent Document 1). However, in the air conditioning control based on the detection result of the presence or absence of an indoor person using a human sensor or the like, it is difficult to control the temperature or humidity in consideration of the heat generated by the indoor equipment.

  If the room temperature rises when the room is unattended, if the room temperature rise is due to the heat generated by the operating equipment, the indoor environment is recommended for the equipment so that the equipment does not fail due to the room temperature being too high. It is preferable to perform air conditioning control so as to keep the temperature or recommended environmental humidity. However, when the room temperature rises due to solar radiation or outside air and the equipment is not operating, the operation of the air conditioner is not preferable because it wastes energy.

  Conventionally, even if the presence / absence of a person in the room can be detected, the operating state of the equipment in the room is not known. For this reason, when the room is unattended, if there is equipment in the room, the air conditioner will be operated regardless of whether the equipment is in operation or not. If not, it will be a waste of energy.

  FIG. 4 is a diagram illustrating outside air, supply air, and return air. FIG. 4 shows the air conditioner 9 and a room 21 that is air-conditioned by the air conditioner 9. The outside air temperature measurement unit 2 includes a temperature sensor that measures a temperature Te outside a building (not shown) including the room 21 at, for example, an outdoor position 9e. The air supply / humidity measurement unit 3 includes a temperature sensor that measures the air sent from the air conditioner 9 into the room 21 (hereinafter also referred to as “indoor”), that is, the dry bulb temperature Ts of the supply air, and the relative humidity THs of the supply air.

To be recorded. FIG. 5 is a diagram for explaining an example of a measurement result. As shown in FIG. 5, a set of data at each measurement time is recorded in the recording unit 8.

  In step S2, a plurality of sets of data including past outside air temperature Te, supply air temperature Ts, supply air humidity RHs, return air temperature Tr, and return air humidity RHr are recorded from the recording unit 8 by the function of the indoor state determination unit 5. Collecting and obtaining the thermal characteristics Y of the room 21 from the distribution of these data.

The thermal characteristic Y may be a straight line Y = AX passing through the origin (Y = Tr−Ts, X = Te−Tr). The thermal characteristic Y may be obtained by, for example, performing regression analysis on the distribution of data of the past measurement result Z to derive Y ′ = AX + B, and obtaining B as 0. The first principal component obtained by principal component analysis May be Y = AX. In the latter case, even if the distribution of the past measurement result Z is large in both the vertical and horizontal directions in FIG.

  In step S3, the indoor heat generation dT is obtained from the thermal characteristics Y and the current measurement results Tei, Tsi, RHsi, Tri, and RHri acquired in step S1 by the function of the indoor state determination unit 5. Since Xi = Tei−Tsi and Yi = Tri−Tsi are obtained from the current outside air temperature Tei, supply air temperature Tsi, and return air temperature Tri, and Yj = AXi is obtained from the thermal characteristics Y, the indoor heat generation dT is Yi−Yj. It can be calculated from

  In step S4, the function of the indoor state determination unit 5 determines whether the indoor heat generation dT is equal to or less than a preset value δt. The value δt is a small value close to 0, such as 0.1. If the indoor heat generation dT is equal to or less than the value δt and the determination result in step S4 is YES, the function of the indoor state determination unit 5 causes the room 21 (that is, the room) to be unmanned and there is no device in operation in the room 21. And the determination result “setting 0” is supplied to the air conditioning control unit 6 and the process proceeds to step S5. The equipment in the room 21 includes equipment that can be a heat generation source, such as an OA equipment.

  In step S5, the operation information corresponding to “setting 0” is acquired from the setting information management unit 7 by the function of the air conditioning control unit 6, and the air conditioner 9 is controlled based on the acquired operation information. The operation information corresponding to “Setting 0” is, for example, air conditioning off, ventilation off, and the like. As described above, when the room is unattended and there is no device operating in the room, the air conditioner 9 is controlled such that the air conditioning is turned off and the ventilation is turned off (that is, the air conditioner 9 is stopped). The setting information management unit 7 turns on / off the air conditioner, turns on / off the ventilation according to the determination result “setting 0” of the indoor state determination unit 5, “setting 1” described later, and “setting 2” described later. Manage and maintain operating information such as temperature and humidity.

  FIG. 7 is a diagram for explaining an example of operation information according to the determination result of the indoor state determination unit 5 managed and held by the setting information management unit 7. As shown in FIG. 7, the setting information management unit 7 turns on / off air conditioning, temperature, humidity, and ventilation on / off for each “setting 0”, “setting 1”, and “setting 2”. The driving information shown is managed and stored in advance. The operation information may be managed and held in the setting information management unit 7 in a changeable manner in accordance with an instruction from the operation unit 103 shown in FIG.

If the indoor heat generation dT exceeds δt and the determination result in step S4 is NO, step S6 is performed by the function of the indoor state determination unit 5 in the supply air temperature Tsi, supply air humidity RHsi, return air temperature Tri, and return air. The supply air absolute humidity Xsi and the return air absolute humidity Xri are calculated from the humidity RHri, and an absolute humidity difference dx = Xri−Xsi between these absolute humidity Xsi and Xri is obtained. The absolute humidity Xsi, Xri can be calculated from, for example, the following formula for calculating the absolute humidity X [kg / kg (DA)].
Absolute humidity X = (Mw × Ep) / (Ma × (Pa−Ep))
Mw: Molecular weight of water (= 18.015)
Ma: Average molecular weight of dry air (= 20.064)
P: Atmospheric pressure (= 101.325 [kPa])
Ep = Ps × RH / 100
RH: Relative humidity [%]
Ps = exp (−0.58002206 × 10 ⁴ /Tk+0.13914993×10−0.48640239/10×
Tk + 0.41764768 / 10 ⁴ × Tk ² −0.14452098 / 10 ⁷ × Tk ³ +
0.65459673 × 10 × log (Tk)) / 10 ³
Tk = T + 273.15
T: Dry bulb temperature [° C]
In step S7, the function of the indoor state determination unit 5 determines whether or not the absolute humidity difference dx is equal to or less than a preset value δx. The value δx is a small value close to 0, such as 0.0001. If the absolute humidity difference dx is equal to or less than the value δx and the determination result in step S7 is YES, the function of the indoor state determination unit 5 determines that the room is unmanned and there are devices in operation, and the determination result “setting” 1 "is supplied to the air conditioning controller 6 and the process proceeds to step S8.

  In step S8, the operation information corresponding to “setting 1” is acquired from the setting information management unit 7 by the function of the air conditioning control unit 6, and the air conditioner 9 is controlled based on the acquired operation information. The operation information corresponding to “Setting 1” includes, for example, a temperature of 30 ° C., a humidity of 50%, and ventilation off based on the recommended temperature and humidity of the indoor device. In this way, when the room is unmanned and there are devices in operation, the air conditioner 9 is controlled so that the room has a temperature and humidity suitable for the indoor devices.

  If the absolute humidity difference dx exceeds the value δx and the determination result in step S7 is NO, the indoor state determination unit 5 determines that the room is manned, and the determination result “setting 2” is sent to the air conditioning control unit 6. The process proceeds to step S9.

  In step S9, the function of the air conditioning control unit 6 acquires the operation information corresponding to “setting 2” from the setting information management unit 7, and controls the air conditioner 9 based on the acquired operation information. The driving information corresponding to “Setting 2” includes, for example, a temperature of 26 ° C., a humidity of 40%, and ventilation on based on human comfort, building management method, and the like. In this way, when the room is manned, the air conditioner 9 is controlled so that the room has a temperature and humidity suitable for people.

  In this embodiment, there are three indoor states, namely, “the room is unmanned and no equipment is in operation in the room”, “the room is unattended and there is equipment in the room” and “the room is manned” It is possible to appropriately and efficiently control the indoor environment in which people and equipment are mixed by discriminating (or estimating) the state and controlling the air conditioner 9 according to each indoor state. That is, the air conditioner 9 can be controlled appropriately and efficiently without wasting energy according to the presence or absence of a person in the room and the presence or absence of an operating device.

  Thereby, efficient air-conditioning operation can be realized. By determining the state of “unattended and no operating equipment”, the air conditioning can be stopped without adversely affecting the equipment. By determining the state of “unmanned and operating equipment”, it is possible to reduce air-conditioning energy compared to when manned without adversely affecting the equipment. Because the recommended temperature / humidity range of equipment is generally wider than that of humans, the amount of heat removed by the air conditioning system and the amount of cooling heat can be reduced especially during cooling. Furthermore, since the ventilation which is a factor which increases a cooling calorie | heat_amount can be stopped, a cooling calorie | heat_amount can further be reduced compared with manned time. As a result, the air conditioning energy can be reduced compared to manned time.

  In the first modification, the absolute humidity difference dx obtained by the function of the indoor state determination unit 5 is supplied to the recording unit 8 in step S6 shown in FIG. 3, and the absolute humidity is supplied to the recording unit 8 as shown in FIG. The difference dx may be recorded together with the corresponding outside air temperature Te, supply air temperature Ts, supply air humidity RHs, return air temperature Tr, and return air humidity RHr. FIG. 8 is a diagram illustrating an example of a measurement result obtained by adding the absolute humidity difference dx.

  In the second modified example, the minimum value min (dx) of the past absolute humidity difference dx acquired from the recording unit 8 is obtained by the function of the room state determination unit 5 in step S7, and the absolute humidity obtained in step S6. A value obtained by subtracting the minimum value min (dx) from dx may be compared with the absolute humidity difference δx.

  According to the 1st and 2nd modification, the influence of water vapor generation sources other than the person permanently installed indoors, such as a foliage plant, can be suppressed.

Further, in the third modified example, in S9 shown in FIG. 3, the absolute humidity difference dx obtained in step S6 together with the determination result “setting 2” is supplied to the air conditioning control unit 6 by the function of the indoor state determination unit 5 to By the function of the control unit 6, the frequency of ventilation may be determined according to the magnitude of the absolute humidity difference dx. For example, the ventilation frequency per hour may be obtained by the following formula.
Ventilation frequency = C × α × dx / D
C: Ventilation volume per hour per person (eg 25.5m ³ / h)
D: Volume of the room 21 [m ³ ]
α: Set value (for example, α = D / 0.1)
According to the third modification, when the number of people in the room is small, the frequency of ventilation can be reduced, and the load on the air conditioner 9 can be reduced.

  In the above embodiment and each modified example, the air conditioning control device 10 controls one air conditioner 9 that controls the air conditioning in one room 21, but the air conditioning control device 10 controls the air conditioning in a plurality of rooms 21. Control one air conditioner 9, control a plurality of air conditioners 9 that control the air conditioning of one room 21, or control a plurality of air conditioners 9 that control the air conditioning of a plurality of rooms 21 Also good. Moreover, when controlling the several air conditioner 9 which controls the air conditioning of the several room 21, the air conditioning control apparatus 10 may control the several air conditioner 9 so that the air conditioning of each room 21 may be controlled independently. .

  According to the above-described embodiment and each modification, an appropriate air-conditioning operation according to the indoor state can be performed, so that the air-conditioning energy can be used efficiently. For example, the indoor state determination unit 5 outputs the determination result of the indoor state and the absolute humidity difference dx to the air conditioning control unit 6, and the air conditioning control unit 6 determines at least one of the ventilation frequency and the ventilation amount according to the absolute humidity difference dx. It can also be controlled. The air conditioning control unit 6 controls the air conditioner 9 to increase at least one of the ventilation frequency and the ventilation volume as the number of people in the room (or the number of people in the room) increases and the absolute humidity difference dx increases. Thus, the comfort of the person in the room can be ensured. In addition, the air conditioning control unit 6 controls the air conditioner 9 so as to reduce at least one of the ventilation frequency and the ventilation volume as the number of occupants decreases and the absolute humidity difference dx decreases, so that the load on the air conditioner 9 is reduced. Can be reduced. As a result, appropriate ventilation according to the number of people in the room can be performed.
