  The environment control device 1 includes a controller 11, a first memory 12, a second memory 13, a third memory 14, and an index derivation unit 7. The index deriving unit 7 may have either a configuration provided in the environment control device 1 or a configuration provided separately from the environment control device 1.

The second memory 13 is an outdoor information memory that stores the history of measurement data of outdoor temperature and outdoor humidity acquired from the outdoor information detection unit 32 and the history of measurement data of outdoor wind speed acquired from the wind information detection unit 33.

  The index deriving unit 7 derives an indoor temperature index T1 and an outdoor temperature index T2. The human sensory temperature depends on temperature, humidity, and wind speed, and the indoor temperature index T1 and the outdoor temperature index T2 are derived as follows. The indoor temperature index T1 is derived by [T1 = indoor temperature + (indoor humidity−60) × 0.1−indoor wind speed]. The outdoor temperature index T2 is derived by [T2 = outdoor temperature + (outdoor humidity−60) × 0.1−outdoor wind speed]. The derivation formulas for the indoor temperature index T1 and the outdoor temperature index T2 are based on the theory that when the humidity increases by 10%, the sensory temperature increases by 1 ° C., and when the wind speed increases by 1 m / s, the sensory temperature decreases by 1 ° C.

The air conditioner 21 performs the cooling operation when the controller 11 is turned on, and stops the cooling operation when the controller 11 is turned off. The mechanical ventilation device 22 performs a mechanical ventilation operation when the controller 11 is turned on, and stops the mechanical ventilation operation when the controller 11 is turned off. The natural ventilation device 23 performs a natural ventilation operation when the controller 11 is turned on, and stops the natural ventilation operation when the controller 11 is turned off.

  The flowchart of FIG. 2 shows the operation of the environment control device 1. The environmental control device 1 acquires indoor and outdoor environmental information (temperature, humidity, wind speed) from the environmental information detection unit 3 (step S1). Next, the index deriving unit 7 calculates the indoor temperature based on each data acquired from the environment information detecting unit 3 (including each data stored in the first memory 12 and the second memory 13 as necessary). The index T1 and the outdoor temperature index T2 are derived (step S2). Next, the controller 11 selects a control mode of the control device 2 based on a predetermined algorithm (step S3). Control modes include an air conditioning mode, a mechanical ventilation mode, a natural ventilation mode, and a stop mode.

  Then, the controller 11 determines whether or not the selected control mode is the air conditioning mode (step S4). When the selected control mode is the air conditioning mode, the controller 11 turns on the cooling operation of the air conditioning device 21, controls off the mechanical ventilation operation of the mechanical ventilation device 22, and turns off the natural ventilation operation of the natural ventilation device 23. Control (step S7). When the selected control mode is not the air conditioning mode, the controller 11 determines whether or not the selected control mode is the mechanical ventilation mode (step S5). When the selected control mode is the mechanical ventilation mode, the controller 11 turns off the cooling operation of the air conditioner 21, turns on the mechanical ventilation operation of the mechanical ventilation device 22, and controls the natural ventilation operation of the natural ventilation device 23. On control is performed (step S8). When the selected control mode is not the mechanical ventilation mode, the controller 11 determines whether or not the selected control mode is the natural ventilation mode (step S6). When the selected control mode is the natural ventilation mode, the controller 11 controls the cooling operation of the air conditioner 21 to OFF, controls the mechanical ventilation operation of the mechanical ventilation device 22 to OFF, and controls the natural ventilation operation of the natural ventilation device 23. On control is performed (step S9). When the selected control mode is not the natural ventilation mode, the controller 11 determines that the selected control mode is the stop mode, and performs the cooling operation of the air conditioner 21, the mechanical ventilation operation of the mechanical ventilator 22, and the natural ventilation device. The natural ventilation operation 23 is controlled to be off (step S10).

  In the mechanical ventilation mode, the cooling operation of the air conditioner 21 may be turned off, the mechanical ventilation operation of the mechanical ventilation device 22 may be turned on, and the natural ventilation operation of the natural ventilation device 23 may be turned off.

  Next, an algorithm used when the controller 11 selects the control mode of the control device 2 will be described with reference to FIG.

FIG. 3 is a conceptual diagram of algorithm selection by the controller 11, where the outdoor temperature index T2 is on the horizontal axis and the indoor temperature index T1 is on the vertical axis. The controller 11 selects a control mode according to the indoor temperature index T1 and the outdoor temperature index T2 derived by the index deriving unit 7. In FIG. 3, a straight line 100 indicates T1 = T2. In the region 101 on the indoor temperature index T1 side with the straight line 100 as a boundary, the outdoor temperature index T2 is lower than the indoor temperature index T1 (the outdoor is cooler than the indoor). Further, the outdoors temperature index T2 side of the area 102 to the linear 100 to the boundary, the indoor temperature indicator T1 is lower than the outdoor temperature index T2 (cool more indoor than outdoor). The straight line 100 may be included in any of the regions 101 and 102.

  The controller 11 compares the indoor temperature index T1 derived by the index deriving unit 7 with the outdoor temperature index T2 (first comparison result).

  Further, the controller 11 compares the indoor temperature index T1 derived by the index deriving unit 7 with a threshold H1 (first threshold), a threshold H2 (second threshold), and a threshold H3 (third threshold) (first threshold). Comparison result of 2). The magnitude relationship between the threshold values H1, H2, and H3 is threshold value H1> threshold value H2> threshold value H3. The indoor temperature index T1 includes a comfortable range C1 that is comfortable for indoor persons. The upper limit of the comfortable range C1 is the threshold value H1, and the lower limit of the comfortable range C1 is the threshold value H3. The indoor target temperature is set within the range of threshold value H1> target temperature> threshold value H3, and the threshold value H2 is set to the indoor target temperature set by the target temperature setting unit 4.

  Then, the controller 11 controls the cooling operation of the air conditioner 21, the mechanical ventilation operation of the mechanical ventilation device 22, and the natural ventilation operation of the natural ventilation device 23 based on the first comparison result and the second comparison result, respectively.

  Specifically, when the indoor temperature index T1 is equal to or higher than the threshold value H1, the controller 11 selects the air conditioning mode, controls the cooling operation of the air conditioner 21 to be on, controls the mechanical ventilation operation of the mechanical ventilator 22 to be off, and naturally ventilates. The natural ventilation operation of the device 23 is turned off.

  On the other hand, when the indoor temperature index T1 is less than the threshold value H1 and greater than or equal to the threshold value H2, the controller 11 performs the following processing. First, when the intersection of the indoor temperature index T1 and the outdoor temperature index T2 belongs to the region 101 (T1> T2), the mechanical ventilation mode is selected, the cooling operation of the air conditioner 21 is turned off, and the machine of the mechanical ventilator 22 is controlled. The ventilation operation is turned on and the natural ventilation operation of the natural ventilation device 23 is turned on. On the other hand, when the intersection of the indoor temperature index T1 and the outdoor temperature index T2 belongs to the region 102 (T1 <T2), the stop mode is selected, the cooling operation of the air conditioner 21, the mechanical ventilation operation of the mechanical ventilator 22, and the natural The natural ventilation operation of the ventilator 23 is controlled off.

  On the other hand, when the indoor temperature index T1 is less than the threshold value H2 and greater than or equal to the threshold value H3, the controller 11 performs the following processing. First, when the intersection of the indoor temperature index T1 and the outdoor temperature index T2 belongs to the region 101 (T1> T2), the natural ventilation mode is selected, and the cooling operation of the air conditioner 21 is controlled to be off. The ventilation operation is turned off, and the natural ventilation operation of the natural ventilation device 23 is turned on. On the other hand, when the intersection of the indoor temperature index T1 and the outdoor temperature index T2 belongs to the region 102 (T1 <T2), the stop mode is selected, the cooling operation of the air conditioner 21, the mechanical ventilation operation of the mechanical ventilator 22, and the natural The natural ventilation operation of the ventilator 23 is controlled off.

  When the indoor temperature index T1 is less than the threshold value H3, the controller 11 performs the following process. First, when the intersection of the indoor temperature index T1 and the outdoor temperature index T2 belongs to the region 101 (T1> T2), the stop mode is selected, the cooling operation of the air conditioner 21, the mechanical ventilation operation of the mechanical ventilator 22, the natural The natural ventilation operation of the ventilator 23 is controlled off. On the other hand, when the intersection of the indoor temperature index T1 and the outdoor temperature index T2 belongs to the region 102 (T1 <T2), the natural ventilation mode is selected, and the cooling operation of the air conditioner 21 is controlled to be off. The ventilation operation is turned off, and the natural ventilation operation of the natural ventilation device 23 is turned on.

  For example, the indoor temperature index T1 may drop at night or the like, and indoor people may feel cold (indoor temperature index T1 <threshold value H3). At this time, if the outside air warms up at dawn and the outdoor temperature index T2 rises and exceeds the indoor temperature index T1, the natural ventilation operation of the natural ventilation device 23 is controlled to be turned on, and warm outdoor air is taken in indoors. Can suppress over-cooling. Thus, when the indoors are too cold, the indoor thermal environment is improved at low cost by natural ventilation, and the comfort of indoor persons is improved.

  Furthermore, the controller 11 controls each device of the control device 2 based on an indoor temperature index T1 that represents the temperature of a human being indoors and an outdoor temperature index T2 that represents the temperature of a human being outdoors. Therefore, since the thermal environment control is performed in consideration of the thermal sensation in which a person feels the heat and cold, the accuracy of the thermal environment control for improving human comfort is improved.

  And the control content of the control apparatus 2 by the controller 11 is sequentially memorize | stored in the 3rd memory 14 which functions as a control log memory. The display device 6 can display the control status and control history of the control device 2 by the environment control device 1 with reference to the third memory 14.

  Further, the environmental control system may omit the mechanical ventilation device 22 by setting the threshold value H1 = the threshold value H2. In this case, the same effect as described above can be obtained.

  The index deriving unit 7 sets the indoor temperature index T1 and the outdoor temperature index T2 to [T1 = indoor temperature + (indoor humidity−60) × 0.1], [T2 = outdoor temperature + (outdoor humidity−60) × 0.1]. It should be noted that the derivation formulas for the indoor temperature index T1 and the outdoor temperature index T2 are not limited to the formulas shown in the present embodiment, as long as they are formulas representing human temperature. The index deriving unit 7 may derive the indoor temperature index T1 and the outdoor temperature index T2 using, for example, expressions representing the Misnar sense temperature and the Linke sense temperature.

  Then, when the indoor temperature index T1 is equal to or higher than the threshold value H1, the controller 11 controls the cooling operation to be on and the natural ventilation operation to be off.

  When the indoor temperature index T1 is less than the threshold value H2 and greater than or equal to the threshold value H3, the controller 11 turns off the cooling operation and turns on the natural ventilation operation if the outdoor temperature index T2 is lower than the indoor temperature index T1.
