The aperture for the temperature control cold valves 31 spent in the public area that sensor 11 measures, water is freezed by adjusting, by public area
Temperature maintains setting value, while the indoor humidity judgement that temperature and humidity controller measures according to humidity sensor in public area 12 is
It is no to continue executing with indoor temperature control methods control program.Indoor temperature control methods are specially：Temperature sensor 11 in public area
The temperature of measurement is sent to programmable controller 17, programmable controller 17 is compared the temperature of measurement with desired temperature
Compared with, the aperture of cold valves 31 is calculated by pid control algorithm, then sent the opening amount signal of cold valves 31 to cold water valve actuator 9,
The aperture that cold valves 31 are completed by cold water valve actuator 9 controls.
Programmable controller 17 is surveyed while public area temperature control is carried out by the humidity sensor 12 in public area
The humidity of public area is measured, as the humidity H in public areazDuring more than humidity set point (such as 70%), then indoor humidity control is switched to
The aperture of programme-control cold valves 31 processed, starts to perform indoor humidity control methods control program, i.e., is set and sent according to humidity measurements
Air temperature setting value, the wind pushing temperature pair that then programmable controller 17 measures according to the wind pushing temperature sensor 10 on ajutage
The aperture of cold valves 31 is controlled, and then controls water-carrying capacity, and wind pushing temperature is maintained into setting value.Specific method is：When public
The humidity H that humidity sensor 12 in area measureszDuring more than 70%, wind pushing temperature setting value is 20 DEG C, programmable controller 17
By the wind pushing temperature that wind pushing temperature sensor 10 measures compared with wind pushing temperature setting value, calculated by pid control algorithm
The aperture of cold valves 31, then the opening amount signal of cold valves 31 is sent to cold water valve actuator 9, completed by cold water valve actuator 9 cold
The aperture control of water valve 31.After 10 minutes, if the humidity that wind pushing temperature sensor 10 measures still is more than 70%, using every 10
The method that minute reduces by 1 DEG C of wind pushing temperature setting value, until when humidity is less than or equal to 70%, wind pushing temperature setting value is kept not
Become.When the humidity that wind pushing temperature sensor 10 measures is less than 65%, indoor temperature control methods are switched to again, i.e., according to public
The aperture of temperature control cold valves 31 in public area that temperature sensor 11 measures in area.
Fig. 3 is indoor temperature control methods control program flow chart, and for indoor temperature control methods, public domain is by interior
The influence of the wet interference of heat, indoor temperature is measured using the temperature sensor 11 being arranged in public domain, by measured value TzWith room
Interior desired temperature is Tz,setCompare, fiducial value is inputted into indoor temperature controller, control signal is produced, is performed by cold valves
Device 9 controls cold valves 31, the aperture of cold valves is adjusted, to ensure indoor temperature TzMaintain setting value Tz,set。
Fig. 4 is indoor humidity control methods control program flow chart, for indoor humidity control methods, sets wind pushing temperature first
Initial set value Ts,setFor 20 DEG C, ajutage is interior to be influenceed by the wet interference of air-supply heat, utilizes the air-supply being arranged in ajutage
Temperature sensor 10 measures wind pushing temperature, by measured value TsWith wind pushing temperature setting value Ts,setCompare, fiducial value is inputted and blown
