As a result, it is possible to provide home sales support showing the humidity control effect.

Hereinafter, the processing contents of the humidity control effect simulation means 1 in the humidity control effect simulation apparatus will be described more specifically.

First, a simulation of a change in moisture absorption / release weight of the humidity control building material 10 is performed.

As procedure 1, the horizontal axis represents the water content (wt%),
The relative humidity (% RH) is plotted on the vertical axis, and the equilibrium moisture content curve 16 is obtained.
(See FIG. 10), and this is converted into a mathematical expression. Then, the material thickness of the humidity control building material 10 is divided into layers of several millimeters, and based on the equilibrium water content curve 16, the first moisture content of the unit thickness layer (the first layer on the surface) of the humidity control building material 10 in contact with the atmosphere A is determined as the first value. The relative humidity B of the material hollow air in the layer is determined (see FIG. 11).

As a procedure 2, based on the following formula, the difference E between the atmosphere A and the relative humidity B of the hollow material air and the saturated steam partial pressure C obtained from the temperature are used to calculate a steam partial pressure difference E relating to moisture absorption and desorption. Ask. -Atmospheric relative humidity A-Material hollow space relative humidity B = Relative humidity difference D for moisture absorption and desorption D-Saturated water vapor partial pressure C at evaluation x Relative humidity difference for moisture absorption and desorption D = Water vapor partial pressure difference for moisture absorption and desorption E Note that the temperature of each layer of the humidity control building material 10 was the same because there was almost no difference from the atmosphere. Further, at the real life level, the temperature hardly affects the amount of moisture absorbed and released by building materials, but rather the relative humidity and the amount of absorbed and released moisture have a great effect. In order to calculate the moisture absorption / desorption rate, it is necessary to determine the water vapor partial pressure difference from the relative humidity difference at each temperature.

As the procedure 3, the atmosphere and the moving steam amount F of the first layer are calculated based on the following formula from the water vapor partial pressure difference E, the moisture conductivity 17 and the unit layer thickness obtained in the procedure 2 (FIG. 12). -Steam partial pressure difference E x moisture conductivity 17 x layer thickness of the unit thickness layer = atmosphere and amount of moving steam F of the first layer F As the fourth step, the first layer material hollow gap relative humidity B obtained in the first step, From the difference H of the relative humidity G of the hollow space of the second layer obtained in the same manner as in Procedure 1, and the saturated water vapor partial pressure C obtained from the temperature, based on the following equation, the first layer and the second layer are separated. The water vapor partial pressure difference I relating to the movement of moisture is obtained (see FIG. 13).・ Relative humidity relative to the hollow space of the first layer B−Relative humidity relative to the hollow space of the second layer G = differential H ・ Saturated steam partial pressure C at the time of evaluation × difference H = steam partial pressure difference I involved in moisture absorption / release I From the water vapor partial pressure difference I between the first layer and the second layer and the moisture conductivity 17 obtained in the procedure 4, the moving water vapor amount J between the first layer and the second layer is calculated based on the following equation (FIG. 14). -Water vapor partial pressure difference I x moisture conductivity 17 x layer thickness of unit thickness layer = moving water vapor amount J of the first and second layers J As step 6, the third layer and subsequent layers up to the last layer of the humidity control building material 10 Repeat the calculation.

In step 7, the total weight of each layer after moisture absorption and desorption is calculated as the total moisture absorption and desorption amount. This overall balance can be represented by the water vapor transfer amount F of the first layer.

In order to verify the above, as shown in FIG. 15, an electronic balance 31 is placed in a thermo-hygrostat 30 and a humidity control building material 10 having a back surface and a small surface covered with aluminum tape 32 thereon. Is installed, the temperature in the thermo-hygrostat 30 is fixed to 25 ° C., and the relative humidity is set to be repeated for 12 hours in the range of 50% to 90%, and the weight variation of the humidity control building material 10 is changed at one minute intervals. The data is read by the data logger 33. Compare this measured value with the simulation result performed under the same temperature and humidity conditions,
The unit thickness of the simulation result is adjusted so that both are approximated.

Using the obtained unit thickness, the moisture absorption / desorption behavior under the conditions different from the above was simulated, and the result as shown in FIG. 17 was obtained. According to FIG. 17, it was possible to obtain a simulation result that was very close to the actual measurement value. This indicates that the simulation was able to accurately grasp the behavior of the humidity control building material 10 under the required environmental conditions.

As described above, the moisture balance of the humidity control building material 10 is not a single unit of the humidity control building material 10 but a layer of several millimeters. Therefore, the equilibrium moisture content curve 16 can be used.

According to the equilibrium moisture content curve 16, the moisture content (wt.
%), It is possible to calculate the relative humidity (% RH) corresponding to the hollow material at the unit thickness.

By using the moisture conductivity 17,
It is possible to calculate the moisture transfer between materials and between materials.

Regarding the heat transfer in the humidity control building material 10, since there is almost no temperature difference inside the humidity control building material 10, it is possible to easily calculate the water vapor pressure in the material by calculating the temperature difference between the room and the room as 0. it can.

Therefore, even with the humidity control building material 10 having substantially the same moisture absorption / desorption performance, the moisture absorption of the material itself is low.
The moisture absorption and desorption is performed using the entire material thickness 18 with high moisture conductivity 17, and the low moisture conductivity 17 does not use the entire material thickness 18 for moisture absorption, but the material itself has high moisture absorption performance. Although the characteristics are different from those possessed, a simulation can be performed based on the difference in the characteristics.

Next, indoor humidity is predicted using the above simulation.

As procedure 1, the sum (total amount) N of the steam weights before the operation of the humidity control building material 10 per unit time is determined (FIG. 1).
8). The sum of the weight of steam before the operation of the humidity control building material 10 per unit time N = the weight of steam inflow by ventilation K + the weight of steam discharged from occupants L + the ventilation residual amount of steam weight Q in the previous unit time M Procedure 2
The relative humidity O in the room is calculated from the temperature per unit time using the total amount N of water vapor. Then, based on the relative humidity O, the indoor moisture-absorbing building material performs moisture absorption / release behavior, and the moisture absorption / release amount P is calculated. The moisture absorption / desorption amount P is subtracted from the total water vapor amount N to calculate the humidity-controlled indoor water vapor weight Q (see FIG. 19). -Indoor water vapor amount after humidity control Q = Total water vapor amount N-Moisture absorption and release amount P determined by relative humidity O As step 3, relative humidity R is calculated using indoor water vapor amount Q after humidity control, and moisture absorption and release of building materials is calculated. The humidity control effect is 24.

The above procedures 1 to 3 are repeated. At this time, the obtained indoor water vapor amount Q after the humidity control is defined as the water vapor weight Q per unit time before the next procedure 1.

By using the weight fluctuation simulation of the humidity control building material 10 and the indoor humidity prediction, a work area required for achieving the target humidity is obtained, or a humidity control effect obtained by defining the work area. 24 can be predicted.

[0049] For example, "Tokyo August August
Simulation is performed for “when 0 is used”.
The following simulation conditions are used. The values calculated by SMASH are used for the outside temperature and humidity and the room temperature. "Simulation conditions 1 ・ Tokyo 2nd to 4th August 10th tatami room on the 2nd floor (master bedroom) ・ 2 adults 21:00 to 7pm Room occupancy 50g / person / hour steam discharge ・ Air conditioner 21:00 to Use for 2 hours at 22:00 Set temperature to 26 ° C Ventilation rate 0.5 times / hour ・ Construction company C's humidity control building material 10 is installed on the entire ceiling (17.4 square m) Cross is not installed. The results are as shown. According to FIG. 20, it was confirmed that the humidity change in the living room was leveled by the humidity control building material 10.

Also, by setting the construction area, the characteristics of the actual humidity control building material 10 and the virtual humidity control building material 10 can be applied to the indoor prediction simulation, and the humidity control effect 24 can be predicted. In addition, by summarizing the regularity of the parameters of the virtual building material used in the simulation, it is possible to obtain an equation for simply determining whether the new humidity control building material 10 has reached the required performance.

For example, in order to obtain a humidity control building material 10 satisfying the following simulation conditions, it is presumed that the following formula must be satisfied. "Simulation condition 2 ・ Tokyo ・ Overall of master bedroom ceiling ・ Air conditioner used from 21:00 to 23:00 Ventilation frequency 0.5 times / hour ・ Two adults 21:00 to 7:00 Room time 50g / person / hour water vapor discharge Furniture not furnished No cloth ・ Target environment The appearance rate of 80% RH or less is 95% throughout the year. ”The required performance of the humidity control building material 10 is a simple formula. {Equilibrium moisture content difference of 60-95% RH (%)} × {moisture conductivity 17 (g / m / h / mmHg)}
> 0.05 and ・ Material absolute dry specific gravity x material thickness 18 (mm) x $ 60-95% RH
Equilibrium moisture content difference (%)} × {moisture conductivity 17 (g / m /
h / mmHg)> 2.0 It should be noted that the values to be achieved in the above two equations are changed according to changes in the environmental conditions and the target environment.

Included in this invention.

For example, input and output may be performed via communication, and the humidity control effect simulation means may be software information stored in a recording medium.
