Description

  The present invention relates to a mold growth amount calculation apparatus and a mold growth amount calculation method for calculating a predicted growth amount of mold in a target space and notifying a mold warning.

  In recent years, cool tubes have been used as air conditioning using natural energy. A cool tube is embedded in the ground to efficiently exchange heat between the outside air and geothermal heat. In summer, the outside air is cooled by geothermal heat, and in winter, the outside air is heated by geothermal heat.

Japanese Patent No. 3785987

  Conventionally, such a cool tube has not been cleaned. However, during the rainy season and summer season, the situation becomes hot and humid, and there is a concern that mold may be generated in the cool tube. For this reason, it is desirable to predict mold growth in the cool tube and perform cleaning based on the prediction result.

  Various methods based on temperature, relative humidity, and the like are considered for predicting mold growth (see, for example, Patent Document 1). However, the conventional method for calculating the predicted growth amount of mold targets ideal conditions, and is not necessarily a calculation method suitable for the actual situation.

  Therefore, the inventors measured the amount of mold growth in the cool tube while periodically cleaning the cool tube. As a result, mold is basically killed by cleaning.However, molds that are difficult to clean remain even after cleaning, and the mold remains without being removed, and this residual mold affects the subsequent growth of mold. I found out that

  The present invention has been made on the basis of the above knowledge, and an object thereof is to provide a mold growth amount calculation apparatus and a mold growth amount calculation method capable of calculating a predicted growth amount of mold according to a situation close to reality. And

  The mold growth amount calculation apparatus according to the present invention is based on an environmental information acquisition unit that acquires environmental information of a target space, environmental information acquired by the environmental information acquisition unit, and a degree of cleaning of members provided in the target space. A predicted growth amount calculation unit that calculates a predicted growth amount of mold generated in the member.

  In the mold growth amount calculation apparatus according to the present invention, the predicted growth amount calculation unit is based on not only the environmental information of the target space but also the degree of cleaning of the member provided in the target space, and the predicted growth amount of mold generated in the member. Is calculated. As a result, the expected growth amount of mold can be calculated in consideration of mold remaining after cleaning, and therefore, the predicted growth amount of mold can be calculated in accordance with a situation close to reality. In addition, a cleaning degree shows the ease of wiping off mold | fungi.

  The degree of cleaning indicates the ease of wiping off mold, and the predicted growth amount calculation unit seems to increase the predicted growth amount of mold generated on a member having a low degree of cleaning compared to the predicted growth amount of mold generated on a member having a high degree of cleaning. In addition, the predicted growth amount may be calculated. A member with a low degree of cleaning is more likely to have a higher mold residue after cleaning than a member with a high degree of cleaning. Therefore, in this mold growth amount calculation device, when the degree of cleaning is low, the predicted growth amount is calculated so that the predicted growth amount is larger than when the degree of cleaning is high. The predicted growth of mold can be calculated.

  If the predicted growth amount calculated by the predicted growth amount calculation unit exceeds a threshold value, an alarm notification unit may be further provided to notify an alarm. In this mold growth amount calculation device, when the predicted growth amount exceeds the threshold value, the alarm notification unit notifies the alarm, so that mold cleaning can be promoted at an appropriate time.

  If the predicted growth amount calculated by the predicted growth amount calculation unit exceeds the first threshold value, an alarm notification unit may be further provided that notifies a cleaning warning that prompts the member to be cleaned. In this mold growth amount calculation device, when the predicted growth amount exceeds the first threshold value, the alarm notification unit notifies the cleaning alarm, so that mold cleaning can be promoted at an appropriate time.

  When the predicted growth amount exceeds a second threshold value that is smaller than the first threshold value, the alarm notification unit may notify a visual alarm that prompts the member to visually check the member. In this mold growth amount calculation device, when the predicted growth amount exceeds a second threshold value that is smaller than the first threshold value, the alarm notification unit notifies a visual alarm, and thus prompts visual confirmation of mold prior to the notification of the cleaning alarm. be able to.

  A cleaning determination unit that determines execution of the cleaning of the member is further provided, and the predicted growth amount calculation unit predicts the predicted growth amount without being based on the degree of cleaning when the cleaning determination unit has not yet determined the cleaning of the member. When the execution of cleaning of the member is determined even once by the cleaning determination unit, the predicted growth amount may be calculated based on the degree of cleaning. At the time of member installation, mold does not grow in the target space, but once mold grows, mold may remain after cleaning. Therefore, in this mold growth amount calculation device, when the cleaning determination unit has not determined the execution of cleaning of the member, the predicted growth amount is calculated without being based on the degree of cleaning. When it is determined that the member is to be cleaned, the predicted growth amount is calculated based on the degree of cleaning. Thereby, the predicted growth amount of mold can be calculated according to the situation close to reality. The cleaning determination unit may determine execution of cleaning of the member by any means. For example, the warning notification unit may determine the execution of the cleaning of the member based on the notification of the cleaning alarm, or may determine the execution of the cleaning of the member based on a reset operation by an administrator or the like.

  The predicted growth amount calculation unit may reset the predicted growth amount when the cleaning determination unit determines that the member is cleaned. When the cleaning of the member is executed, mold generated in the member provided in the target space is removed by cleaning by an operator or the like. Therefore, in this mold growth amount calculation device, when the cleaning determination unit determines that the cleaning of the member is performed, the predicted growth amount is reset to calculate the predicted growth amount of the mold in accordance with the situation close to reality. Can do.

  The predicted growth amount calculation unit may calculate a predicted growth amount by calculating a predicted unit growth amount of mold per set time and integrating the predicted unit growth amount. In this mold growth amount calculation apparatus, the predicted growth amount can be calculated efficiently by calculating the predicted growth amount by integrating the predicted unit growth amount of mold per set time.

  The predicted growth amount calculation unit may calculate the predicted unit growth amount only when the target space is a growth-capable environment where mold can grow. In this mold growth amount calculation device, the predicted unit growth amount is calculated only when the target space is a growth-capable environment where mold growth is possible, so unnecessary calculation processing is omitted and the predicted growth amount is calculated efficiently. can do.

  The environmental information may include temperature and relative humidity. In this mold growth amount calculation apparatus, the temperature and relative humidity that greatly affect the mold growth rate are included in the environmental information, so that the mold growth rate can be appropriately evaluated.

  The target space may be a space in the cool tube. The inside of the cool tube is particularly prone to mold during the rainy season and summer, and it is difficult to completely prevent mold from occurring only with advance measures. For this reason, the mold generated in the cool tube can be cleaned in a timely manner by calculating the predicted growth amount of the mold in the space in the cool tube.

  The mold growth amount calculation method according to the present invention is based on the environmental information acquisition step of acquiring environmental information of the target space, the environmental information acquired in the environmental information acquisition step, and the degree of cleaning of members provided in the target space. And a predicted growth amount calculating step of calculating a predicted growth amount of mold generated in the member.

  In the mold growth amount calculation method according to the present invention, in the predicted growth amount calculation step, the predicted growth amount of mold generated in the member based on not only the environmental information of the target space but also the degree of cleaning of the member provided in the target space. Is calculated. As a result, it is possible to calculate the predicted growth amount of mold generated on the member in consideration of the mold remaining after cleaning, and therefore, it is possible to calculate the predicted growth amount of mold according to a situation close to reality.

  If the predicted growth amount calculated in the predicted growth amount calculation step exceeds a threshold value, an alarm notification step of notifying an alarm may be further provided. In this mold growth amount calculation method, when the predicted growth amount exceeds a threshold value, an alarm is notified in the alarm notification step. For this reason, mold cleaning can be promoted at an appropriate time.

  A cleaning determination step for determining execution of cleaning of the member is further provided. In the predicted growth amount calculation step, when the cleaning determination step has not yet determined execution of cleaning of the member, the predicted growth amount is not based on the cleaning degree. When the execution of cleaning of the member is determined even once by the cleaning determination step, the predicted growth amount may be calculated based on the degree of cleaning. When the building is completed, mold does not grow in the target space, but once mold grows, mold may remain after cleaning. Therefore, in this mold growth amount calculation method, when the cleaning determination step has not yet determined execution of cleaning of the member, the predicted growth amount is calculated without being based on the degree of cleaning. When the execution of cleaning is determined, the predicted growth amount is calculated based on the degree of cleaning. Thereby, the predicted growth amount of mold can be calculated according to the situation close to reality.

  According to the present invention, it is possible to calculate the expected growth amount of mold according to a situation close to reality.

  Hereinafter, with reference to the drawings, preferred embodiments of a mold growth amount calculation apparatus and a mold growth amount calculation method according to the present invention will be described in detail. In the present embodiment, the target space is the space in the cool tube, and the expected growth amount of mold generated in the member provided in the space is calculated. In the drawings, the same or corresponding parts are denoted by the same reference numerals. .

(Configuration of mold growth amount calculation device)
FIG. 1 is a block diagram illustrating a mold growth amount calculation apparatus according to an embodiment. As shown in FIG. 1, the mold growth amount calculation device 1 of this embodiment includes an environment information acquisition device 2, a mold monitoring device 3, and an alarm output device 4. The mold growth amount calculation device 1 is also called a mold alarm device.

  The environmental information acquisition device 2 acquires environmental information of a space in the cool tube (hereinafter referred to as “space A”) and acquisition date information that is information on the date of acquisition of the environmental information. The environmental information includes at least temperature and relative humidity. The environmental information acquisition device 2 periodically acquires environmental information. The environmental information acquired by the environmental information acquisition device 2 may be an instantaneous value or an average value from the previous acquisition to the current acquisition. The interval at which the environmental information acquisition device 2 acquires the management information can be set to one hour, for example. It is preferable that the environmental information acquisition apparatus 2 acquires the environmental information of the space A at the cool tube outlet. As the environment information acquisition device 2, for example, BEMS (Building Energy Management System) can be used.

  Based on the information transmitted from the environment information acquisition device 2, the mold monitoring device 3 calculates a predicted growth amount of mold generated in a member provided in the space A (hereinafter referred to as “member B”). Examples of the member B include concrete, pipes, heat insulating materials, cable racks, cable ducts, protective tubes, pipe heat insulating materials, and the like (see FIG. 4). In addition, the mold monitoring device 3 performs alarm notification control based on the calculated estimated growth amount of mold. The mold monitoring apparatus 3 includes an environment information acquisition unit 31, a predicted growth amount calculation unit 32, an alarm notification unit 33, and a cleaning determination unit 34.

  The environment information acquisition unit 31 periodically acquires environment information and acquisition date information from the environment information acquisition device 2. The environment information acquisition unit 31 acquires environment information and acquisition date information, for example, the environment information acquisition unit 31 periodically transmits an information request signal to the environment information acquisition device 2 and receives the information transmission request. This can be done by the information acquisition device 2 transmitting environment information and acquisition date information to the environment information acquisition unit 31.

  The predicted growth amount calculation unit 32 calculates the predicted growth amount of mold generated in the member B. The predicted growth amount of mold is a predicted value of the current growth amount of mold mycelium. The predicted growth amount of mold is calculated based on the environmental information acquired by the environmental information acquisition unit 31, the ease of mold growth of the member B, and the cleaning degree of the member B. The calculation of the predicted growth of mold is performed by calculating the predicted unit growth of mold per set time and integrating the predicted unit growth. The set time as a calculation unit of the predicted unit growth amount can be set to, for example, 1 hour, which is an interval at which the environment information acquisition device 2 acquires management information. Then, the predicted growth amount calculation unit 32 calculates the predicted growth amount of mold for each member B. Details of the expected growth of mold will be described later.

  The warning notification unit 33 notifies a warning when the predicted growth amount calculated by the predicted growth amount calculation unit exceeds a threshold value. The alarm notification by the alarm notification unit 33 is performed when the alarm notification unit 33 instructs the alarm output device 4 to output an alarm. The alarm notified by the alarm notification unit 33 includes a cleaning alarm that prompts the cleaning of the member B and a visual alarm that prompts the user to visually check the member B. The cleaning warning is notified when the predicted growth amount calculated by the predicted growth amount calculation unit exceeds the first threshold value T1. The visual warning is notified when the predicted growth amount calculated by the predicted growth amount calculation unit exceeds the second threshold T2. The second threshold T2 is a threshold smaller than the first threshold T1. The first threshold value T1 can be set to an arbitrary value within a range of 120 [mm] to 250 [mm], for example. The second threshold value T2 can be set to a value that is about half of the first threshold value T1, for example.

  FIG. 2 is a graph showing mold mycelium growth. As shown in FIG. 2, mold (mold mycelia) grows with the passage of time from the time of installation of the member. In particular, mold growth is promoted from May to October, and mold growth is suppressed from November to April. Therefore, the alarm notification unit 33 notifies a cleaning alarm or a visual alarm only during a period during which mold growth is suppressed, that is, a period from November to April. The period for notifying the cleaning alarm or the visual alarm is referred to as an alarm notification period.

  The cleaning determination unit 34 determines the execution of the cleaning of the member B. That is, the cleaning determination unit 34 determines that the cleaning of the member B has been executed. The cleaning determination unit 34 may determine the execution of the cleaning of the member B by any means. For example, the execution of cleaning of the member B may be determined when the cleaning notification is notified by the alarm notification unit 33, and the execution of cleaning of the member B is determined when a reset operation or the like is performed by an administrator or the like. May be. When the cleaning determination unit 34 determines that the cleaning of the member B is performed, the predicted growth amount calculation unit 32 resets the predicted growth amount. Resetting the predicted growth amount means setting the predicted growth amount to zero.

  The alarm output device 4 outputs an alarm instructed from the alarm notification unit 33. That is, the alarm output device 4 outputs a cleaning alarm when instructed to notify a cleaning alarm from the alarm notifying unit 33, and outputs a visual alarm when instructed to notify a visual alarm from the alarm notifying unit 33. As the alarm output device 4, a display device (display) that displays an alarm, an audio output device (speaker) that outputs an alarm sound, a printing device that prints an alarm, or the like can be used.

(Calculation method for predicted growth of mold)
Next, a method for calculating the predicted growth amount of mold by the predicted growth amount calculation unit 32 will be described.

  The amount of mold growth varies depending on the growth possible environment, temperature, relative humidity, material property value of member B, and cleaning degree of member B.

  The growable environment is an environment in which mold can grow, and is an environment in which temperature and relative humidity are within a predetermined range. The temperature range of the growth possible environment is, for example, 15 ° C. or more and 35 ° C. or less. The relative humidity range of the growable environment is, for example, 75% or more. And if space A is a growth possible environment, mold growth is promoted, and if space A is not a growth possible environment, mold growth is not promoted. For this reason, the predicted growth amount calculation unit 32 calculates the predicted growth amount on the assumption that mold grows when the space A is a growth-capable environment.

  When the space A is an environment where growth is possible, the mold growth rate increases as the temperature of the space A increases, and the mold growth rate decreases as the temperature of the space A decreases. Further, when the space A is an environment where growth is possible, the mold growth rate increases as the relative humidity in the space A increases, and the mold growth rate decreases as the relative humidity in the space A decreases. For this reason, the predicted growth amount calculation unit 32 calculates the predicted growth amount based on the temperature and relative humidity of the space A.

  The material characteristic value is a value indicating the tendency of mold growth. That is, the material characteristic value increases as mold grows easily, and the material characteristic value decreases as mold does not grow easily. The material characteristic value varies depending on the material of the member B. For example, in the above-described member B, concrete, piping, heat insulating materials, cable racks, cable ducts, protective pipes, piping heat insulating materials correspond to materials that are prone to mold, that is, materials with high material property values, and water Wet concrete, cable racks, cable ducts, protective pipes, and piping heat insulating materials correspond to materials that are difficult to mold, that is, materials with low material property values. A material having a low material property value has a higher mold growth rate than a material having a high material property value. For this reason, the predicted growth amount calculation unit 32 has a larger expected growth amount of mold occurring in the material member B having a low material characteristic value than the predicted growth amount of mold occurring in the material member B having a high material characteristic value. Thus, the predicted growth amount is calculated.

  The degree of cleaning is a degree indicating the ease of mold wiping. That is, when mold is wiped off, the degree of cleaning increases as mold is removed, and the degree of cleaning decreases as mold remains. The degree of cleaning varies depending on the member B. For example, in member B mentioned above, concrete, piping, a cable rack, a cable duct, and a protection pipe correspond to member B with a high cleaning degree, and a heat insulating material and piping heat insulating material correspond to member B with a low cleaning degree. To do. The member B with a high degree of cleaning has a higher mold residual rate after cleaning than the member B with a low degree of cleaning, which may increase the growth rate of the mold. Therefore, the predicted growth amount calculating unit 32 predicts the predicted growth amount so that the predicted growth amount of mold generated in the member B having a low cleaning degree is larger than the predicted growth amount of mold generated in the member B having a low cleaning degree. Is calculated.

  In this embodiment, a cleaning evaluation value is used as the degree of cleaning. The cleanability evaluation value is lower as the cleaning degree is higher, and is higher as the cleaning degree is lower. That is, the lower the cleaning property evaluation value, the higher the cleaning degree, and the higher the cleaning property evaluation value, the higher the cleaning degree. For this reason, the predicted growth amount calculating unit 32 is configured so that the predicted growth amount of mold generated in the member B having a large cleaning property evaluation value is larger than the predicted growth amount of mold occurring in the member B having a small cleaning property evaluation value. Calculate the predicted growth amount.

  As the cleaning property evaluation value, for example, when mold was wiped off, the area where mold was grown was divided by the area where mold was wiped (area where mold was grown / mold was wiped off) Area). FIG. 3 is a diagram for explaining how to obtain the degree of cleaning. FIG. 3A is an enlarged view of the surface of the member B before cleaning, and FIG. 3B is a diagram of the member B after cleaning. It is a surface enlarged view. Consider the case where mold C is growing on the surface of the member B as shown in FIG. The area where mold C is growing is D1. Thereafter, as shown in FIG. 3B, by wiping the surface of the member B, part or all of the mold C is wiped from the surface of the member B. FIG. 3B shows a state in which a part of the mold C remains on the surface of the member B. The area where mold C is growing is D2. The area D1 and the area D2 refer to the area of the mold C viewed from the direction perpendicular to the surface of the member B. In such a case, the cleaning property evaluation value can be expressed by D1 / (D1-D2).

  Other methods of determining the degree of cleaning are expressed in terms of the color difference, roughness (surface roughness), and ATP (adenosine triphosphate) emission level on the surface of member B before and after mold wiping. Can do. ATP is adenosine triphosphate contained in an organic substance and can be quantified by the amount of luminescence of the substance. When using the ATP emission amount, for example, a value obtained by dividing the ATP emission amount after wiping by the ATP emission amount at the initial stage of the material can be used as the cleaning degree.

  By the way, it is considered that mold does not grow on the member B when the member is installed. Then, mold grows on the member B after the member is installed, but if the member B is cleaned after the mold grows on the member B, the mold B may remain in the mold. Therefore, the predicted growth amount calculation unit 32 calculates the predicted growth amount without being based on the degree of cleaning, and once the cleaning determination unit 34 determines that the cleaning determination unit 34 has not determined the cleaning of the member B. However, when execution of cleaning of the member B is determined, the predicted growth amount is calculated based on the degree of cleaning. In the present embodiment, it is determined whether or not the cleaning determination unit 34 has determined that the cleaning of the member B has never been performed, and whether or not the cleaning notification has been notified by the alarm notification unit 33. . That is, the predicted growth amount calculation unit 32 calculates the predicted growth amount without being based on the degree of cleaning when the warning notification unit 33 has never notified the cleaning warning, and the warning notification unit 33 generates the cleaning warning even once. When notified, the predicted growth amount is calculated based on the degree of cleaning.

  Next, a specific method of calculating the predicted growth amount of mold by the predicted growth amount calculation unit 32 will be described.

Let the expected growth of mold be Lm [mm], the material property value of member B is k ₁ , the cleaning property evaluation value of member B is k ₂ , the temperature is T [° C.], and the relative humidity is RH [%]. Further, the function of the temperature T is f (T), and the function of the relative humidity RH is g (RH).

  When the cleaning determination unit 34 has not yet determined execution of cleaning of the member B, the predicted mold growth amount Lm can be obtained by the following equation (1).

Lm = Σ (k ₁ · f (T) · g (RH) +100) (1)
On the other hand, when the cleaning determination unit 34 determines that the cleaning of the member B is performed even once, the expected growth amount Lm of the mold can be obtained by the following equation (2).

Lm = Σ (k ₁ · k ₂ · f (T) · g (RH)) (2)
In addition, the constant term of Formula (1) is an approximate expression of an actual measurement value. By the way, although it is thought that the mold | fungi have not grown in the member B at the time of member installation, mold | fungi may grow in the member B by the time of completion of a building. Therefore, in equation (1), 100 [mm] is added to the predicted growth amount in consideration of mold growth during that time. On the other hand, in Formula (2), since the consideration of the cleaning evaluation value k _2, not by adding 100 [mm] to the predicted amount of growth as in Equation (1). In the formulas (1) and (2), (k ₁ · f (T) · g (RH) +100) and (k ₁ · k ₂ · f (T) · g (RH)) are prediction units. The amount of growth. In Formula (1) and Formula (2), f (T) can be expressed by a quadratic formula (a ₁ T ² + a ₂ T + a ₃ ) of temperature T, for example, and g (RH) is, for example, , (A ₄ RH ² + a ₅ RH + a ₆ ). a _{1 to} a ₆ are coefficients.

FIG. 4 is a diagram showing material characteristic values and cleaning degrees. As shown in FIG. 4, the concrete and the piping are made of a material that is less prone to mold, and the degree of cleaning is high. Therefore, in these members B, for example, next to the material characteristic value _{k 1} is 0.5, the cleaning evaluation value _{k 2} is 1.0. As the heat insulating material, a material that does not easily generate mold is used, and the degree of cleaning is low. Therefore, in these members B, for example, next to the material characteristic value _{k 1} is 0.5, the cleaning evaluation value _{k 2} becomes 1.2. Concrete wet with water, cable racks, cable ducts, and protective pipes are made of moldy materials and have a high degree of cleaning. Therefore, in these members B, for example, next to the material characteristic value _{k 1} is 1.0, the cleaning evaluation value _{k 2} is 1.0. The pipe heat insulating material uses a material that easily causes mold and has a low degree of cleaning. Therefore, in these members B, for example, next to the material characteristic value _{k 1} is 1.0, the cleaning evaluation value _{k 2} becomes 1.2.

  Then, the predicted growth amount calculation unit 32 calculates the predicted growth amount Lm of mold for each of these members B, for each material characteristic value, or for each cleaning property evaluation value. In the present embodiment, the predicted growth amount calculation unit 32 calculates the expected growth amount Lm of mold for each material characteristic value.

(Method for calculating mold growth)
Next, a method for calculating the mold growth amount will be described. In performing the mold growth amount calculation method, the predicted growth amount Lm is set to 0, the visual alarm frequency Wvn is set to 1, and the cleaning alarm frequency Wcn is set to 1 as initial values. The visual alarm frequency Wvn is the number of times that the visual alarm is notified by the alarm notification unit 33. The cleaning alarm frequency Wcn is the number of times that the alarm notification unit 33 has notified the cleaning alarm.

  FIG. 5 is a flowchart illustrating a mold growth amount calculation method according to the embodiment. As shown in FIG. 5, in the mold growth amount calculation method of this embodiment, first, the environmental information acquisition step (S1) is performed, then the predicted growth amount calculation process (S2) is performed, and then the alarm notification step (S3). Next, a cleaning determination step (S4) is performed. The following processing is performed periodically (for example, every hour).

  In the environmental information acquisition step (S 1), the environmental information acquisition device 2 acquires environmental information and acquisition date information, and the environmental information acquisition unit 31 acquires environmental information and acquisition date information from the environmental information acquisition device 2.

  In the predicted growth amount calculation process (S2), the predicted growth amount Lm of mold is calculated for each member B having the same material characteristic value.

  FIG. 6 is a flowchart showing the predicted growth amount calculation step. As shown in FIG. 6, in the predicted growth amount calculation process (S2), first, the predicted growth amount calculation unit 32 is based on the environment information (temperature T and relative humidity RH) acquired by the environment information acquisition unit 31. It is determined whether A is a growth-capable environment (S21). That is, the predicted growth amount calculation unit 32 sets the temperature T acquired by the environment information acquisition unit 31 within a set range (for example, 15 ° C. or more and 35 ° C. or less) and the relative humidity RH acquired by the environment information acquisition unit 31 is set. It is determined whether it is within the range (75% or more). If the predicted growth amount calculation unit 32 determines that the space A is not a growth-capable environment (S21: NO), the predicted growth amount calculation step (S2) ends.

  On the other hand, if the predicted growth amount calculation unit 32 determines that the space A is a growth-promoting environment (S21: YES), next, whether or not the cleaning notification unit 33 has notified the cleaning alarm once, that is, It is determined whether or not the cleaning determination unit 34 has determined that the cleaning of the member B has never been performed (S22). Here, whether or not the cleaning notification has been notified by the alarm notification unit 33 is determined by whether or not the cleaning alarm frequency Wcn is 1.

  Then, if the predicted growth amount calculation unit 32 determines that the warning notification unit 33 has never notified the cleaning warning (S22: YES), it next calculates the predicted unit growth amount of mold based on the environmental information. (S23), the predicted growth amount Lm is calculated (S24). That is, the predicted growth amount calculation unit 32 calculates the predicted unit growth amount based on the environmental information (temperature T and relative humidity RH) acquired by the environmental information acquisition unit 31, and integrates the predicted unit growth amount. The predicted growth amount Lm is calculated. The predicted growth amount Lm and the predicted unit growth amount can be obtained from the above-described equation (1).

  On the other hand, if the predicted growth amount calculation unit 32 determines that the cleaning notification has been notified even once by the alarm notification unit 33 (S22: NO), next, the mold is checked based on the environmental information and the degree of cleaning (cleanability evaluation value). A predicted unit growth amount is calculated (S25), and a predicted growth amount Lm is calculated (S26). That is, the predicted growth amount calculation unit 32 calculates the predicted unit growth amount based on the environmental information (temperature T and relative humidity RH) acquired by the environmental information acquisition unit 31, and integrates the predicted unit growth amount. The predicted growth amount Lm is calculated. The predicted growth amount Lm and the predicted unit growth amount can be obtained from the above-described equation (2).

  Then, when the predicted growth amount calculation unit 32 calculates the predicted growth amount Lm, the predicted growth amount calculation step (S2) ends.

  FIG. 7 is a flowchart showing the alarm notification step. As shown in FIG. 7, in the alarm notification step (S3), first, a visual alarm notification process (S31) is performed, and then a cleaning alarm notification process (S32) is performed.

  FIG. 8 is a flowchart showing visual alarm notification processing. As shown in FIG. 8, in the visual warning notification process (S31), first, the warning notification unit 33 determines whether or not the predicted growth amount Lm is larger than the second threshold T2 (S311). If the warning notification unit 33 determines that the predicted growth amount Lm is not greater than the second threshold value T2 (S311: NO), the visual warning notification process ends.

  On the other hand, if the warning notification unit 33 determines that the predicted growth amount Lm is greater than the second threshold value T2 (S311: YES), the warning notification unit 33 then determines whether or not a visual warning has been notified once. (S312). Whether or not a visual alarm has been notified by the alarm notification unit 33 is determined by whether or not the visual alarm frequency Wvn is 1. And if the alarm notification part 33 determines with the alarm notification part 33 notifying the visual alarm even once (S312: NO), it will complete | finish a visual alarm notification process.

  On the other hand, if the warning notification unit 33 determines that the visual notification has not been notified by the warning notification unit 33 (S312: YES), it next determines whether or not it is a warning notification period (S313). Whether or not it is an alarm notification period is determined by whether or not the acquisition date information acquired by the environment information acquisition device 2 is within the period from November to April, which is an alarm notification period. And if the alarm notification part 33 determines that it is not an alarm notification period (S313: NO), a visual alarm notification process will be complete | finished.

  On the other hand, if the alarm notification unit 33 determines that it is the alarm notification period (S313: YES), it next determines whether it is the alarm notification date (S314). That is, in this embodiment, a visual alarm is notified only on a predetermined date in January. The alarm notification date can be, for example, the first day of each month. And if the alarm notification part 33 determines with it not being an alarm notification day (S314: NO), a visual alarm notification process will be complete | finished.

  On the other hand, if the alarm notification unit 33 determines that it is the alarm notification date (S314: YES), it next notifies a visual alarm (S315). The alarm notification unit 33 includes the contents of a visual alarm for a member B that is prone to mold (a member B having a material characteristic value of 1.0), and a member B that has a material characteristic value of 0.5 (a member having a material characteristic value of 0.5). The content of the visual alarm for B) is made different. For example, the visual alarm for the member B that is prone to mold is the content shown in FIG. 9, and the visual alarm for the member B that is difficult to mold is the internal tone shown in FIG. In this case, it is preferable to include a cleaning method in the case of mold growing in the content of the alarm.

  Then, when notifying a visual alarm, the alarm notifying unit 33 counts up (+1) the number of visual alarms Wvn (S316), and ends the visual alarm notification process.

  FIG. 11 is a flowchart showing the cleaning warning process. As shown in FIG. 11, in the cleaning warning notification process (S32), first, the warning notification unit 33 determines whether or not the predicted growth amount Lm is larger than the first threshold T1 (S321). If the warning notification unit 33 determines that the predicted growth amount Lm is not greater than the first threshold value T1 (S321: NO), the cleaning warning notification process is terminated.

  On the other hand, if the warning notification unit 33 determines that the predicted growth amount Lm is larger than the first threshold T1 (S321: YES), it next determines whether it is a warning notification period (S322). Whether or not it is the alarm notification period is the same as in step S313 of the visual alarm process (S31), the acquisition date information acquired by the environment information acquisition device 2 is within the period from November to April, which is the alarm notification period. Judgment is made by whether or not there is. And if the warning notification part 33 determines that it is not a warning notification period (S322: NO), a cleaning warning notification process will be complete | finished.

  On the other hand, if the alarm notification unit 33 determines that it is the alarm notification period (S322: YES), it next determines whether it is an alarm notification date (S323). That is, in this embodiment, a cleaning warning is notified only on a predetermined day in January. The alarm notification date can be, for example, the first day of each month. And if the warning notification part 33 determines with it not being a warning notification day (S323: NO), a cleaning warning notification process will be complete | finished.

  On the other hand, if the alarm notification unit 33 determines that it is an alarm notification date (S323: YES), it next notifies a cleaning alarm (S324). The alarm notification unit 33 includes the contents of the cleaning alarm for the member B that is prone to mold growth (member B having a material characteristic value of 1.0) and the member B that is difficult to mold mold (member having a material characteristic value of 0.5). The content of the cleaning warning for B) is different. For example, the cleaning alarm for the member B that tends to grow molds may have the contents shown in FIG. 12, and the cleaning alert for the member B that hardly molds may have the contents shown in FIG. In this case, it is preferable to include the elapsed period from the previous cleaning and the cleaning method in the content of the alarm.

  Then, when notifying the cleaning alarm, the alarm notifying unit 33 counts up (+1) the cleaning alarm frequency Wcn (S325), and ends the cleaning alarm notification process.

  FIG. 14 is a flowchart showing the cleaning determination step. As shown in FIG. 14, in the cleaning determination step (S4), first, the cleaning determination unit 34 determines whether or not cleaning has been executed (S41). If the cleaning determination unit 34 determines that cleaning is not being performed (S41: NO), the process returns to step S322 of the cleaning alarm notification process (S32) (see FIG. 11), and performs the above-described process again.

  On the other hand, if the cleaning determination unit 34 determines that cleaning has been executed (S41: YES), the cleaning amount Lm and the number of visual alarms Wvn are reset (S42). That is, the predicted growth amount Lm is reset to 0, which is an initial value, and the visual alarm frequency Wvn is reset to 1, which is an initial value. Then, the cleaning determination unit 34 ends the cleaning determination step.

  Thus, in the present embodiment, the predicted growth amount Lm of mold generated in the member B is calculated based on not only the environmental information of the space A but also the degree of cleaning of the member B provided in the space A. Thereby, the mold growth growth Lm can be calculated in consideration of mold remaining after cleaning, and therefore the mold growth growth Lm can be calculated in accordance with a situation close to reality.

  In addition, a member with a low degree of cleaning is more likely to have a greater residual amount of mold after cleaning than a member with a high degree of cleaning. Accordingly, when the degree of cleaning is low, the predicted growth amount Lm is calculated so that the predicted growth amount Lm is larger than when the cleaning degree is high, so that the expected growth amount Lm of mold is adjusted to the situation close to reality. Can be calculated.

  Further, when the predicted growth amount Lm exceeds the first threshold value T1, a cleaning warning is notified, so that mold cleaning can be promoted at an appropriate time. Furthermore, since the visual warning is notified when the predicted growth amount Lm exceeds the second threshold T2 that is smaller than the first threshold T1, the visual confirmation of mold can be promoted prior to the notification of the cleaning warning.

  Moreover, when the building is completed, mold does not grow in the space A, but once mold grows, mold may remain after cleaning. Therefore, when the cleaning determination unit 34 has not yet determined the cleaning of the member B, the predicted growth amount Lm is calculated without being based on the degree of cleaning, but the cleaning determination unit 34 cleans the member B even once. Is determined, the predicted growth amount Lm is calculated based on the degree of cleaning. Thereby, the predicted growth amount Lm of mold can be calculated in accordance with the situation close to reality.

  Further, when the cleaning of the member B is executed, mold generated on the member provided in the target space by the cleaning by the worker or the like is removed. Therefore, when the cleaning determination unit 34 determines that the cleaning of the member B is performed, the predicted growth amount Lm can be calculated according to a situation close to reality by resetting the predicted growth amount Lm.

  Further, by calculating the predicted growth amount Lm by integrating the predicted unit growth amount of mold per set time, the predicted growth amount Lm can be calculated efficiently.

  In addition, since the predicted unit growth amount is calculated only when the space A is a growth-capable environment where mold can grow, it is possible to efficiently calculate the predicted growth amount Lm without using unnecessary calculation processing.

  Further, since the temperature T and the relative humidity RH that greatly affect the mold growth rate are included in the environmental information, the mold growth rate can be appropriately evaluated.

  In addition, the inside of the cool tube is particularly prone to mold during the rainy season and summer, and it is difficult to completely prevent mold from occurring only with prior measures. For this reason, the mold generated in the cool tube can be cleaned in a timely manner by calculating the predicted growth amount Lm of the mold in the space in the cool tube.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment.

  For example, in the above-described embodiment, the alarm notification unit has been described as notifying the alarm when the predicted growth amount exceeds the threshold. However, the alarm need not necessarily be notified.

  Moreover, although the said embodiment demonstrated as what notifies a visual alarm and a cleaning alarm, the content of the alarm to notify is not specifically limited, You may notify the alarm which only shows the estimated growth amount of mold | fungi.

  Moreover, although the said embodiment demonstrated as what determines the execution of cleaning of a member by the cleaning determination part, it does not necessarily determine execution of cleaning of a member. In this case, it is only necessary to determine whether the predicted growth amount is calculated based on the degree of cleaning or whether the predicted growth amount is calculated without being based on the degree of cleaning with the notification of the cleaning warning. Similarly, the predicted growth amount Lm and the number of visual alarms Wvn may be reset upon notification of the cleaning alarm.

  In the above embodiment, the predicted growth amount is calculated by accumulating the predicted unit growth amount, and the specific arithmetic expression is exemplified. However, the calculation method of the predicted growth amount is not particularly limited, Various known methods can be employed.

  Moreover, in the said embodiment, although object space was demonstrated as the space in a cool tube, object space is not specifically limited, Various space can be made into object.
