An air conditioner operation control means (Patent Document 1) is disclosed.

JP 2003-85586 A

  However, although the invention of the above-mentioned Patent Document 1 considers the comfort of the occupants, it simply considers the comfort of the occupants above and below the room temperature, such as in a store. There is a problem that the comfort of various people with different bodily sensations cannot be considered. In addition to the above-mentioned Patent Document 1, there are many inventions such as an air-conditioning control system and an air-conditioning control method that determine the operating state in consideration of the comfort of a person in the room taking into account the internal and external environmental conditions. Although it is disclosed, for example, a store clerk (resident in a store) and a customer (in-store fluid) have people who have significantly different personal environmental conditions even if they are in the same environmental condition. However, there has been no proposal for solving the difference between pleasant and unpleasant feelings caused by differences in the environmental conditions of each experience.

  The present invention has been made in view of such circumstances, and an object of the present invention is to operate the air conditioner so as to create an environment in which the resident in the store and the fluid in the store are not uncomfortable. The object is to provide a store air-conditioning control method for controlling the state.

  In order to solve the above-mentioned problem, the air conditioning control method for a store according to claim 1 is characterized in that a resident comfortable environmental condition that a resident in the store staying in the store for a predetermined time or more feels comfortable, and a predetermined time in the store. The operating condition of the air conditioner is determined based on the optimal environmental conditions in the store calculated by applying a predetermined weight to each of the environmental conditions including the fluid comfortable environmental conditions that the in-store fluidist feels comfortable. It is characterized by controlling.

  According to this, when the air conditioner is operated based only on the resident comfort environment condition (fluid comfort condition) considering the comfort of the resident (store fluid), the store fluid ( It is considered that the resident in the store may feel uncomfortable. However, as described above, each of the environmental conditions including the resident comfortable environment condition and the fluid comfortable environment condition is weighted with predetermined weights. By calculating the optimal environmental conditions in the store, it is possible to consider the comfort of both the resident in the store and the fluid in the store within the store, and based on the value of the resident in the store and the fluid in the store It is possible to control the operation of the air conditioner so that both of the environmental conditions are not uncomfortable.

  The store air-conditioning control method according to claim 2 is the store air-conditioning control method according to claim 1, wherein the resident comfortable environment condition is a resident in-store belonging to a comfortable sensation environment index range in which a person feels comfortable. It is calculated by the resident comfortable feeling environment index of the resident, and the fluid comfortable environment condition is calculated by the fluid comfortable feeling environment index of the in-store fluid who belongs to the comfortable feeling environment index range.

  According to this, since the sensation environment index determined for each individual is used to calculate the resident comfortable environment condition and the fluid comfortable environment condition, it is possible to objectively measure each comfort, Resident comfortable environmental conditions and fluid comfortable environmental conditions can be obtained.

  The store air-conditioning control method according to claim 3 is the store air-conditioning control method according to claim 2, wherein the environmental condition is a temperature representing temperature, and the resident occupant experience sensation environment index and the fluid comfort The sensation environment index is determined based on the temperature outside the store and the amount of clothes of the in-store resident and the in-store fluid who depend on the temperature.

  Thereby, the discomfort by heating / cooling can be prevented by considering temperature as environmental conditions. Since the Resident Comfort Experience Index and the Fluid Experience Environment Index are determined based on the temperature outside the store and the amount of clothing that depends on the temperature outside the store, the Resident Comfort Experience Condition and the Fluid Comfort Experience Index The calculated resident comfortable environment condition and fluid comfortable environment condition are appropriate values for preventing pleasantness and discomfort due to heating and cooling.

  The store air-conditioning control method according to claim 4 is the store air-conditioning control method according to claim 2 or 3, wherein the resident comfortable experience environment index and the fluid comfort experience environment index are determined by a temperature outside the store. When the temperature is lower than a predetermined reference value, it takes a substantially minimum value of the comfortable feeling environment index range, and when the temperature outside the store is higher than a predetermined reference value, it takes a substantially maximum value of the comfortable feeling temperature index range. And

  Thus, for example, in winter when the temperature outside the store is low, the Resident Comfort Experience Index (Resident Comfort Experience Temperature Index) and the Fluid Comfort Experience Environment Index (Flower Comfort Experience Temperature Index) are substantially minimum values. By doing so, the resident comfort environment condition (resident comfort temperature) and the fluid comfort environment condition (fluid comfort temperature) calculated therefrom are made the lowest while maintaining the comfort of the resident and the fluid. be able to. Therefore, the optimal environmental conditions in the store (optimum environmental temperature in the store) that are finally calculated are also low, and the air conditioning is operated at a relatively low temperature that does not lose the comfort of the resident and the flower. Can be improved. In summer and the like when the temperature rises, the energy saving effect can be similarly obtained by operating the air conditioning at a high temperature.

  The store air-conditioning control method according to claim 5 is the store air-conditioning control method according to any one of claims 2 to 4, wherein the predetermined weighting includes the resident comfortable environment condition and the fluidizer. It is performed by adding a safe temperature in the store that can avoid a heat shock caused by a temperature difference between the inside of the store and the outside of the store to a comfortable environment condition.

  Thereby, by calculating the safe temperature in the store to avoid heat shock and adding the safe temperature in the store to the weighting, it is possible to prevent a person who has just entered the store from outside the store from causing a heat shock. .

  The store air-conditioning control method according to claim 6 is the store air-conditioning control method according to any one of claims 3 to 5, wherein the temperature outside the store depends on the temperature and humidity outside the store. Correction is performed based on enthalpy.

  According to this, the amount that is determined or calculated based on the temperature outside the store as compared to the case where no correction is made by correcting the temperature outside the store based on the enthalpy representing the magnitude of thermal energy Can be obtained more appropriately.

  The store air-conditioning control method according to claim 7 is the store air-conditioning control method according to claim 5 or 6, wherein the predetermined weight is the resident comfortable environment condition, the fluid comfort environment condition, the store It is characterized by increasing the order of the internal safety temperature.

  According to this, by placing more weight on the fluid comfort environment conditions of the in-store fluidizers consisting mainly of customers than the resident comfort environment conditions of the shop residents consisting mostly of employees, Customer comfort can be improved. Furthermore, by setting the weight of the safe temperature in the store to be the heaviest, air conditioning can be operated based on a safe temperature that is less likely to cause a heat shock for both the in-store resident and the in-store fluid.

  The air conditioning control method for a store according to claim 8 is the air conditioning control method according to any one of claims 1 to 7, wherein the operation state of the air conditioner is heating when the average temperature is relatively low. It is controlled to perform only the operation, and is controlled to perform only the cooling operation when the average temperature is relatively high. According to this, it is possible to prevent the cooling operation from being performed when there is a rare day when the temperature is relatively low at a time when the average temperature is relatively high so that the heating operation is not normally performed. . Conversely, it is possible to prevent the heating operation from being performed when the average temperature is relatively low. Therefore, it is possible to prevent sudden cooling operation without adjusting the air conditioner or the like at a time when the heating operation is usually performed, and it is possible to prevent failure of the air conditioner. On the contrary, sudden heating operation when there are many cooling operations can be prevented, and failure of the air conditioner can also be prevented.

  The store air-conditioning control method according to claim 9 is the store air-conditioning control method according to any one of claims 1 to 8, wherein the control is performed when the temperature outside the store is in a general appropriate temperature range. On the other hand, the operation of the air conditioner is preferentially stopped. According to this, when the temperature outside the store is in a general appropriate temperature range, the person in the store does not feel uncomfortable without operating the air conditioner, so the air conditioning operation is stopped. As a result, it is possible to suppress wasteful power consumption and improve the energy saving effect.

  The operating condition of the air conditioner based on the optimal environmental conditions in the store calculated by applying a predetermined weight to each of the environmental conditions including the resident comfortable environmental condition of the resident in the store and the fluid comfortable environment condition of the fluid in the store By controlling the above, the comfort of both the resident in the store and the fluid in the store can be taken into consideration.

Hereinafter, first to third embodiments of the present invention will be described in detail with reference to the drawings. In the first to third embodiments of the present invention, the case where temperature is used as the environmental condition will be described. In addition, the temperature sensory index, which is one of the sensory environment indices, includes indoor temperature, humidity, airflow, radiant heat, air pressure, the amount of clothes in the room (heat resistance value from the skin surface to the outer surface of the clothes, 1clo = 0.155m ² ° C / W), using SET * (standard effective temperatures) determined by activity. To simplify the explanation, the humidity, airflow, and air pressure in the room are 50%, 0.1 m / s, and 760 mmHg, respectively, and the amount of activity of people in the room is 59.8 W / m ² for both resident and resident in the store. And constant. Furthermore, the tables shown in the drawings, including those described later, show data when the temperature outside the store is 1 ° C. to 35 ° C. for the sake of simplicity. Of course, the same data is also shown for other outside store temperatures. Is set.

(First embodiment)
A first embodiment will be described with reference to the accompanying drawings. FIG. 1 is a functional block diagram illustrating a configuration of a store air-conditioning control system 1 that is air-conditioned based on the store air-conditioning control method according to the first embodiment. A measurement unit 10, an in-store optimum temperature calculation unit 37, and an air conditioner 43 are provided. The store outside temperature measurement unit 10 measures the temperature outside the store and transmits the measurement result to the store optimum temperature calculation unit 37 as the store outside temperature data 13. The store optimum temperature calculation unit 37 is configured to calculate the store optimum temperature based on the store outside temperature data 13 and output the store optimum temperature data 39 based on the calculation result. 72, a comfortable comfortable fluid temperature calculation unit 74, and an in-store optimum temperature calculation unit 70.

  Here, a specific configuration of the resident comfortable temperature calculation unit 72 will be described. FIG. 2 is a functional block diagram showing the configuration of the resident comfortable temperature calculation unit 72. As shown in FIG. As shown in the figure, the resident comfortable temperature calculation unit 72 calculates the resident comfortable temperature based on the store outside temperature data 13, and uses the resident comfortable temperature data 24 based on the calculation result as the optimum temperature 70 in the store. The resident wear amount data storage unit 17, the resident comfortable SET * determination unit 15, and the resident comfort calculation unit 23 are provided. The resident clothing amount data storage unit 17 stores the resident clothing amount based on the temperature data outside the store as data.

  The resident SET * determination unit 15 extracts the resident clothing amount data 19 based on the value of the resident clothing amount based on the store outside temperature data 13, and the resident in the store based on the resident clothing amount data 19. The resident comfortable SET * representing the sensation temperature index that the user feels comfortable is determined, and the resident comfortable SET * data 21 is transmitted to the resident comfortable temperature calculation unit 23.

  The resident comfortable temperature calculation unit 23 calculates the resident comfortable temperature, which is a temperature that the resident feels comfortable based on the resident comfortable SET * data, and calculates the resident comfortable temperature data 24 based on the calculation result in the store. This is transmitted to the optimum temperature calculation unit 70. Next, a specific configuration of the fluid comfort temperature calculation unit 74 will be described. FIG. 3 is a functional block diagram showing the configuration of the fluid comfort temperature calculation unit 74. As shown in the figure, the fluid comfort temperature calculation unit 74 is based on the outside-store temperature data 13, and the fluid comfort temperature Is calculated, and the comfortable flower temperature data 35 based on the calculation result is output to the optimum temperature 70 in the store. The flower clothing amount data storage unit 27, the comfortable flower SET * determination unit, and the comfortable flower temperature A calculation unit 33 is included.

  The fluid clothing amount data storage unit 27 stores fluid clothing amount based on temperature data outside the store as data. The fluid comfort SET * determination unit 25 extracts the fluid clothing amount data 29 based on the value of the fluid clothing amount based on the temperature data outside the store, and based on the fluid clothing amount data 29, the fluid fluid in the store Is determined and transmitted to the fluid comfort temperature calculation unit 33. The fluid comfort temperature calculation unit 33 calculates a fluid comfort temperature, which is a temperature that the fluid feels comfortable based on the fluid comfort SET * data 31, and calculates fluid comfort temperature data 35 based on the calculation result. This is transmitted to the in-store optimum temperature calculation unit 70.

  The in-store optimum temperature calculation unit 70 actually calculates and obtains the optimum temperature in the store based on the received resident comfortable temperature data 24 and the fluid comfort temperature data 35, and the optimum temperature data 39 in the store based on the calculation result. Is transmitted to the control unit 41.

  The air conditioner 43 actually adjusts the temperature in the store and determines the air conditioning mode, and has a control unit 41, which controls the operating state of the air conditioner 43 based on the in-store optimum temperature data 39. And control the operation.

  Next, the store air-conditioning control method according to the present embodiment will be described with reference to the flowchart of FIG. 4 and the tables of FIGS. FIG. 5 is a table showing the relationship between the store outside temperature, the resident clothing amount, and the resident comfortable SET *, and FIG. 6 is a table showing the relationship between the store outside temperature, the fluid clothing amount, and the fluid comfort SET *. FIG. 7 is a table showing the relationship between the resident comfort SET * and the resident comfort temperature, and FIG. 8 is a table showing the relationship between the fluid comfort SET * and the fluid comfort temperature.

  First, in step S1, the temperature outside the store is measured by the store outside temperature measuring unit 10. As a specific numerical value, in this embodiment, the temperature outside the store is measured as 1 ° C.

  Proceeding to step S <b> 2, resident clothing amount data 19 based on the store outside temperature data 13 is extracted from the resident clothing amount data storage unit 17. Similarly, fluid clothing amount data 29 based on the outside store temperature data 13 is extracted from the fluid clothing amount data storage unit 27. As described above, when the temperature outside the store is 1 ° C., as shown in FIG. 5, the resident clothing amount is 1 [clo] (about winter suit), and as shown in FIG. The person's clothing amount is 2 [clo]. These values are for those who are in the store who stay in the store for a relatively short time rather than those who stay in the store for a long time when the temperature outside the store is as low as 1 ° C. Is determined statistically based on the fact that is generally thick, and is not particularly limited to this value.

  Proceeding to step S3, the resident comfortable SET * determining unit 15 determines the resident comfortable SET * using the outside store temperature data 13 and the resident clothing amount data 19 based on the resident clothing amount. Similarly, the fluidizer comfort SET * determination unit 25 determines the fluidizer SET * using the fluidizer clothing amount data 29 based on the store outside temperature data 13 and the fluidizer clothing amount. Specifically, when the outside-store temperature is 1 ° C. as described above, the resident occupant SET * is determined to be 19.5 ° C. because the resident clothing amount is 1 [clo] as shown in FIG. As shown in FIG. 6, since the amount of fluid clothing is 2 [clo], the fluid comfort SET * is determined to be 23.7 ° C. In addition, the value of the resident comfort SET * is a value around 20 ° C., which is near the minimum value of the sensation comfort index range, so that the air conditioner 43 is efficiently operated with less energy when the temperature outside the store is low. As long as it is in the range of about 20 ° C. to 27 ° C., the comfort is not lost, so any value may be used, and the value is not particularly limited to this value. In addition, the value of the fluid comfort SET is determined in consideration of the sufficient comfort of the fluid, and is not limited to this, so that the set temperature of the subsequent air conditioner 43 is lowered to about 20 ° C., The energy saving effect may be improved.

  According to this, the resident comfortable SET * and the fluid comfortable SET * need only be within a range of about 20 ° C. to 27 ° C. (comfort body temperature index range). For example, when the temperature in winter is low, By determining the resident comfortable SET * and the fluid comfortable SET * to be around the minimum value of 20 ° C, the air conditioning set temperature will not eventually become too high, and the energy-saving effect can be improved. By determining the user comfort SET * and the fluid comfort SET * at around the maximum value of 27 ° C., the air conditioning set temperature does not become too low, and the energy saving effect can be improved.

  In step S4, the resident comfortable temperature calculation unit 23 calculates the resident comfortable temperature using the resident comfortable SET * data 21 based on the resident comfortable SET *. Similarly, the fluid comfort temperature calculation unit 33 calculates the fluid comfort temperature using the fluid comfort SET * data 35 based on the fluid comfort SET *. Specifically, when the resident comfort SET * is 19.5 ° C. and the fluid comfort SET * is 23.7 ° C. as described above, the resident comfort temperature is 18 ° C. as shown in FIGS. The fluid comfortable temperature is 13 ℃. In addition, each comfortable temperature with respect to each SET * shown in FIG. 7 and FIG. 8 is calculated by a known calculation method.

  In this way, since the SET * that is determined for each resident in the store and each fluider in the store is used to calculate the resident comfortable temperature and the fluid comfortable temperature, measure each comfort objectively. Therefore, precise resident comfort temperature and fluid comfort temperature can be obtained.

  In step S5, the in-store optimum temperature calculation unit 70 assigns predetermined weights to the resident comfort temperature data 24 based on the resident comfort temperature and the fluid comfort temperature data 35 based on the fluid comfort temperature, thereby optimizing the inside of the store. Calculate the temperature. Specifically, when the resident comfort temperature is 18 ° C. and the fluid comfort temperature is 13 ° C. as described above, for example, when the resident comfort temperature is weighted by 20%, the fluid comfort temperature is weighted by 80%. The optimal temperature in the store is 18 x 0.2 + 13 x 0.8 = 14 ° C. In this embodiment, 20% is given to the resident comfortable temperature and 80% is given to the fluid comfortable temperature as an example. By placing emphasis on in-store fluidizers, which are the majority of the store, the store resident in the store is not considered uncomfortable while taking into account the comfort of the in-store fluidizer first. Absent.

  Proceeding to step S6, the controller 41 determines the operating state of the air conditioner 43 based on the in-store optimum temperature data 39 based on the in-store optimum temperature, and operates. Specifically, since the optimum temperature in the store is 14 ° C. as described above, the control unit 41 determines the operation state of the air conditioner 43 using this temperature as the set temperature, and performs the operation. Naturally, in this case, since the store outside temperature (1 ° C.) is lower than the store optimum temperature (14 ° C.), the air conditioner 43 is controlled to operate in the heating mode.

  Note that the calculation of the fluid comfortable temperature and the calculation of the resident comfortable temperature are independent operations. Therefore, the calculation is not limited to the order described above, and both calculations are completed before the calculation of the optimum temperature in the store in step S5. Any order may be used. For example, the extraction of the fluid clothing amount may be started after the calculation of the resident comfortable temperature is completed. Further, in this embodiment, the case where the value of the store outside temperature 13 is 1 ° C. has been described as a specific example. However, the present invention is not limited to this, and the optimum temperature in the store is exactly the same as the above method regardless of what the temperature is. The air conditioning temperature can be set.

  In general, when the outside temperature of the store is in the range of about 20 ° C to 26 ° C, the SET * of the resident in the store and the SET * of the fluidist in the store are in the range of 20 ° C to 27 ° C even when the air conditioner is not operated. In this case, the control unit 41 does not operate the air conditioner 43 based on the in-store optimum temperature, and stops the operation of the air conditioner 43 by an air conditioner operation stop unit (not shown). In addition, the temperature outside the store that stops this air conditioning (the temperature at which the SET * of the resident in the store and the fluidizer in the store becomes 20 ° C to 27 ° C) is not necessarily 20 ° C to 26 ° C depending on the installation situation of the store and the installation area. It is not a range and can be changed according to the situation. Thereby, the useless operation of the air conditioner 43 when the necessity is low can be prevented, and a high energy saving effect can be obtained.

  According to the present embodiment, discomfort due to heating and cooling can be prevented by considering temperature as an environmental condition. Since the resident comfort SET * and the fluid comfort SET * are determined based on the temperature outside the store and the amount of clothing depending on the temperature, it is calculated from the resident comfort SET * and the fluid comfort SET *. The resident comfortable temperature and the fluid comfortable temperature are appropriate values for preventing pleasantness and discomfort due to heating and cooling.

  When the air conditioner 43 is operated based only on the resident comfort temperature (fluid comfort temperature) in consideration of the comfort of the resident (store fluid), the shop fluid (store resident) However, as described above, by calculating the optimum temperature in the store by performing a predetermined weighting on the resident comfortable environment temperature and the fluid comfortable temperature, the inside of the store is calculated. The comfort of both the resident in the store and the fluid in the store can be considered, and air conditioning is performed so that both the resident in the store and the fluid in the store will not be uncomfortable based on the optimal temperature in the store. The operation of the device can be controlled.

(Second embodiment)
A second embodiment will be described. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 9 is a functional block diagram illustrating a configuration of the store air-conditioning control system 1 that is air-conditioned based on the store air-conditioning control method according to the second embodiment. As shown in the figure, a characteristic configuration different from the first embodiment is that the in-store optimum temperature calculation unit 37 is provided with an in-store safety temperature calculation unit 45. The in-store safety temperature calculation unit 45 calculates the in-store safety temperature 46, which is a temperature at which neither the resident in the store nor the fluid in the store will cause a heat shock based on the temperature outside the store. The in-store safe temperature data 46 based on the calculation result is transmitted to the in-store optimum temperature calculation unit 70.

  Next, a store air-conditioning control method according to the present embodiment will be described with reference to the flowchart shown in FIG. 10 and the above-described FIGS. FIG. 11 is a table showing the relationship between the store outside temperature and the store safe temperature.

  As shown in FIG. 10, in step S <b> 7, the temperature outside the store is measured by the store outside temperature measuring unit 10. As an application of specific numerical values, it is assumed that the store outside temperature is measured as 1 ° C. in order to facilitate comparison with the first embodiment.

  Proceeding to step S 8, the resident clothing amount based on the store outside temperature data 13 is extracted from the resident clothing amount data storage unit 17. Similarly, the amount of fluid clothing based on the outside store temperature data 13 is extracted from the fluid clothing amount data storage unit 27. Specifically, since the temperature outside the store is 1 ° C., the resident clothing amount is 1 [clo] as shown in FIG. 5, and the fluid clothing amount is 2 [clo] as shown in FIG. clo].

  In step S9, the resident comfort SET * determination unit 15 determines the resident comfort SET * using the store outside temperature data 13 and the resident clothes amount data 19 based on the resident clothes amount. Similarly, the fluidizer comfort SET * determination unit 25 determines the fluidizer SET * using the fluidizer clothing amount data 29 based on the store outside temperature data 13 and the fluidizer clothing amount. Specifically, when the temperature outside the store is 1 ° C., as shown in FIG. 5, the amount of resident clothing is 1 [clo], so the resident comfortable SET * is determined to be 19.5 ° C. As shown in FIG. 2, since the amount of fluid clothing is 2 [clo], the fluid comfort SET * is determined to be 23.7 ° C.

  In step S10, the resident comfortable temperature calculation unit 23 calculates the resident comfortable temperature using the resident comfortable SET * data 21 based on the resident comfortable SET *. Similarly, the fluid comfort temperature calculation unit 33 calculates the fluid comfort temperature using the fluid comfort SET * data 35 based on the fluid comfort SET *. Furthermore, as a characteristic step of the present embodiment, the in-store safe temperature calculation unit 45 calculates the in-store safe temperature by a known calculation method based on the store outside temperature data 13. Specifically, when the resident comfortable SET * is 19.5 ° C. and the fluid comfortable SET * is 23.7 ° C., the resident comfortable temperature is 18 ° C. as shown in FIG. 7 and FIG. Is 13 ° C., and the in-store safety temperature calculated when the store outside temperature is 1 ° C. as shown in FIG. 11 is 16 ° C.

  Proceeding to step S11, in the in-store optimum temperature calculation unit 70, the resident comfort temperature data 24 based on the resident comfort temperature, the fluid comfort temperature data 35 based on the fluid comfort temperature, and the store safety temperature based on the store safety temperature. The optimum temperature in the store is calculated by giving a predetermined weight using the data 46. Specifically, the optimal temperature in the store is weighted by 10% for the resident comfort temperature (18 ° C), 40% for the fluid comfort temperature (13 ° C), and 50% for the in-store safety temperature (16 ° C). Is calculated as 18 × 0.1 + 13 × 0.4 + 16 × 0.5 = 15 ° C. According to this, by placing importance on the fluid comfort environment temperature of the in-store fluidizer, which is mostly made up of customers, rather than the resident comfort temperature of the in-store staff, which is mostly made up of employees, important customers in the store Can enhance the comfort. Furthermore, by making the weight of the safe temperature in the store the heaviest, it is possible to operate the air conditioner based on a safe temperature that is difficult to cause a heat shock for both the resident in the store and the fluid in the store.

  Proceeding to step S12, the operation state of the air conditioner 43 is determined and operated by the control unit 41 based on the in-store optimum temperature data 39 based on the in-store optimum temperature (15 ° C.). Specifically, heating operation at a set temperature of 15 ° C. is performed.

  Similarly to the first embodiment, the air conditioning operation is stopped when the temperature outside the store is in the range of 20 ° C to 26 ° C.

  The calculation of the in-store safety temperature is not necessarily performed in step 10, but from step S7 in which the temperature outside the store is calculated to step S12 that actually controls the operation of the air conditioner, that is, You may perform in the arbitrary steps of step S8-S11. Further, the specific numerical values used in the present embodiment are not limited to these as in the first embodiment.

  According to the present embodiment, in addition to the effect of the first embodiment, by adding the in-store safety temperature to the weighting, the in-store fluid who has just entered the store from outside the store has a rapid temperature It is possible to prevent heat shock due to change. Furthermore, by making the weight of the safe temperature in the store the heaviest, the temperature in the store can be made highly safe for preventing heat shock. In addition, by increasing the weight of the fluid comfortable temperature rather than the resident comfortable temperature, the customer comfort can be further increased to the extent that the employee does not become uncomfortable.

(Third embodiment)
Hereinafter, a third embodiment will be described. The same elements as those in the first or second embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 12 is a functional block diagram illustrating a part of the configuration of the store air-conditioning control system 1 that is air-conditioned based on the store air-conditioning control method according to the third embodiment. In the figure, only the periphery of the enthalpy correction unit 49 and the outside-humidity measurement unit 51 added to the configuration of the second embodiment is shown, and the other parts are the same as the configuration shown in FIG. It is.

  As shown in the figure, as part of the configuration for controlling the air conditioning in the present embodiment, an outside-store humidity measuring unit 51 for measuring the outside-store humidity and an outside-store temperature measuring unit 10 The enthalpy is calculated from the measured temperature outside the store and the humidity outside the store measured by the outside-humidity measuring unit 51, and the above-mentioned temperature outside the store is corrected based on the enthalpy to calculate the corrected temperature outside the store. An enthalpy correction unit 49 is provided. The enthalpy correction unit 49 can transmit data to the in-store optimum temperature calculation unit 37.

  Next, the store air-conditioning control method according to the present embodiment will be described with reference to the flowchart shown in FIG. 13 and FIGS. 5 to 8 and 11 described above. As shown in FIG. 13, in step 13, the temperature outside the store is measured by the outside temperature measuring unit 10, and the humidity outside the store is measured by the outside humidity measuring unit 51. As an application of specific numerical values, it is assumed that the store outside temperature is measured as 1 ° C. in order to facilitate comparison with the first and second embodiments. In this embodiment, since not only the store outside temperature but also the store outside humidity is measured, this value is set to 70%.

  Proceeding to step 14, the resident clothing amount based on the outside store temperature data 13 is extracted from the resident clothing amount data storage unit 17. Similarly, a fluid clothing amount based on the store outside temperature data 13 is extracted from the fluid clothing amount data storage unit 27. Specifically, since the temperature outside the store is 1 ° C., as shown in FIG. 5, when the temperature outside the store is 1 ° C., the amount of resident clothing is 1 [clo]. As shown, the amount of fluid clothing is 2 [clo].

  Proceeding to step 15, as a characteristic process in the present embodiment, based on the enthalpy calculated by a known method based on the temperature outside the store and the humidity outside the store, a predetermined correction is performed on the temperature outside the store, and the outside correction temperature is calculated. To do. Specifically, if the enthalpy is calculated when the temperature outside the store is 1 ° C and the humidity outside the store is 70%, it can be seen that it is almost the same value as the enthalpy when the temperature is 3 ° C and the humidity is 50%. Adjust the standard when the standard humidity is 50%, and calculate the outside correction temperature as 3 ℃.

  Proceeding to step 16, the resident comfortable SET * determination unit 15 determines the resident comfortable SET * using the resident clothing amount data 19 based on the resident clothing amount 19 based on the corrected temperature outside the store. Similarly, the fluidizer comfort SET * determination unit 25 determines the fluidizer SET * using the fluidizer clothing amount data 29 based on the fluidizer clothing amount based on the outside correction temperature. Specifically, when the store outside temperature is 1 ° C., the store outside correction temperature is 3 ° C. as calculated in step 15, and the resident clothing amount is 1 [clo] as shown in FIG. The resident comfortable SET * is determined to be 19.7 ° C. Further, as shown in FIG. 6, the amount of fluid clothing is 2 [clo] and the fluid comfort SET * is determined to be 23.9 ° C.

  Proceeding to step 17, the resident comfortable temperature calculation unit 23 calculates the resident comfortable temperature using the resident comfortable SET * data 21 based on the resident comfortable SET *. Similarly, the fluid comfort temperature calculation unit 33 calculates the fluid comfort temperature using the fluid comfort SET * data 35 based on the fluid comfort SET *. Further, the in-store safety temperature calculation unit 45 calculates the in-store safety temperature based on the outside store correction temperature data based on the outside store correction temperature calculated in step 16. Specifically, when the resident comfortable SET * is 19.7 ° C. and the fluid comfortable SET * is 23.9 ° C., the resident comfortable temperature is 18 ° C. as shown in FIG. 7 and FIG. The fluid comfortable temperature is 13 ℃. Then, the in-store safety temperature corresponding to FIG. 11 is calculated to be 18 ° C. using the outside store correction temperature (3 ° C.) obtained by correcting the store outside temperature (16 ° C.) in step 16.

  Proceeding to step 18, in the in-store optimum temperature calculation unit 70, the resident comfort temperature data 24 based on the resident comfort temperature, the fluid comfort temperature data 35 based on the fluid comfort temperature, and the store safety temperature based on the store safety temperature. The optimum temperature in the store is calculated by giving a predetermined weight using the data 46. Specifically, the resident comfortable temperature (18 ° C), the fluid comfortable temperature (13 ° C), and the above-mentioned in-store safety temperature (18 ° C) are the same as in the second embodiment, 10%, 40%, When 50% weighting is performed, 18 × 0.1 + 13 × 0.4 + 18 × 0.5 = 16 ° C.

Proceeding to step 19, the operation state of the air conditioner 43 is determined and operated by the control unit 41 based on the in-store optimum temperature data 39 based on the in-store optimum temperature.
Specifically, heating operation at a set temperature of 16 ° C. is performed.

  According to the present embodiment, in addition to the effects of the second embodiment, a correction is made to the outside temperature based on the enthalpy representing the magnitude of the thermal energy, and the resident comfort SET * These amounts can be obtained as more appropriate values by obtaining the fluid comfort SET * and the in-store safe temperature. Therefore, the comfort of the resident in the store and the fluid in the store and the improvement of the heat shock prevention effect can be improved with higher accuracy.

  Next, based on the time classification data classified based on the average outside store temperature for each predetermined time in the configuration of the first to third embodiments, the time-dependent control for switching between cooling and heating is given priority over the control. By providing the means (not shown) in the control unit 41, the cooling operation is performed when the average temperature is relatively high, when the average temperature is relatively high, and when the temperature is rarely low. It is possible to prevent this from happening. Conversely, it is possible to prevent the heating operation from being performed when the average temperature is relatively low. Therefore, it is possible to prevent sudden cooling operation without adjusting the air conditioner 43 or the like at a time when the heating operation is usually performed, and to prevent failure of the air conditioner 43. it can. On the contrary, sudden heating operation at the time when there are many cooling operations can be prevented, and the failure of the air conditioner 43 can also be prevented.

  In addition, this invention is not limited to the said embodiment, A various change is possible within the range of the summary of invention. For example, the present embodiment is applied only to the case where the store outside temperature is 1 ° C. Of course, the present embodiment can be applied to any other temperature. In the first to third embodiments, air conditioning is controlled based on SET * as one of the indices representing the bodily sensation environment conditions, but other indices such as PMV and discomfort index may be used. good.
