Start to indicate.At this point, as shown in figure 4, control unit 10 accepts the experimental condition being entered and test starts to indicate.So
Afterwards, control unit 10 starts to test (step S11) after setting the experimental condition accepted.Specifically, in step S11, control
Portion 10 sets experimental condition by storing the experimental condition accepted to RAM.Thereafter, control unit 10 starts to test.
If starting to test, control unit 10 starts the temperature adjustment control (step S12) of the air of air conditioner 80.According to
This, is supplied in laboratory 9 by the air that air conditioner 80 is adjusted temperature from blow-off outlet 84.
Specifically, in step S12, control unit 10 is by carrying out so-called PID control, so that temperature sensor TR is detected

81 air heating efficiency or the air cooling capacity of evaporator 82.In addition, air themperature tune of the control unit 10 in air conditioner 80
Pressure fan 86 is allowed to generate the wind of regulation wind speed in whole.
If the temperature that control unit 10 starts the air of air conditioner 80 adjusts control, adjustment setting humidity PIDH is calculated
(step S13).
Specifically, in step S13, the saturated vapor pressure LW (SVT) of air of the control unit 10 based on set temperature SVT,
The saturated vapor pressure LW (PVT) and setting relative humidity SVH for detecting the air of temperature PVT, calculate adjustment setting humidity PIDH.
Adjustment setting humidity PIDH is that have the steam partial pressure WPT of target gas ST and have to detect with temperature sensor TR

Also, detection temperature PVT is set as " 60 DEG C ", and detecting relative humidity PVH is " 90% ".Moreover, being located at moment " t21 ", set
Temperature SVT is changed to " 30 DEG C ", and setting relative humidity SVH is changed to " 90% ".
At this point, control unit 10 will use the sky of the set temperature SVT " 30 DEG C " obtained from the first storage unit 61 in step S13
It the saturated vapor pressure LW (30 DEG C) (=0.02717) of gas and setting relative humidity SVH " 90% " and is obtained from the first storage unit 61
The air of the detection temperature PVT " 60 DEG C " taken saturated vapor pressure LW (60 DEG C) (=0.15221) calculated result (for example,
16%) it is calculated as adjustment setting humidity PIDH.
If control unit 10 calculates adjustment setting humidity PIDH in step S13, set using the calculated adjustment
Humidity PIDH carries out the humidity adjustment control (step S14) of the air of air conditioner 80.
Specifically, control unit 10 is by carrying out so-called PID control, so that relative humidity sensor HR in step S14
The detection relative humidity PVH of detection, which reaches, adjusts evaporator 82 in the mode that the calculated adjustment of step S13 sets humidity PIDH
Air cooling capacity and humidifier 83 steam supply amount.
If control unit 10 starts humidity adjustment control in step S14, determine whether to terminate test (step in execution
S15).Specifically, control unit 10 is from the time in the adjustment control of step S12 start temperature by step in step S15
In the case where the execution time for the test for including in the experimental condition of S11 setting, determine to terminate test.In other cases, sentence
It is fixed not terminate to test.
Control unit 10 is determining not terminating to test (being no in step S15) and determine to adjust from humidity in step S14 to control
From the time of beginning without the stipulated time in the case where (being no in step S16), the later processing of step S15 is repeated.
