Const float xdata C2=+0.0405; A floating type fixed value of // definition is+0.0405.
Const float xdata C3=-0.0000028; A floating type fixed value of // definition is-0.0000028.
Const float xdata T1=+0.01; A floating type fixed value of // definition is+0.01.
Const float xdata T2=+0.00008; A floating type fixed value of // definition is+0.00008.
Float xdata rh=*p_humidity; A floating type variable of // definition, this variable storage is measured the numerical value of humidity.
Float t=*p_temperature; A floating type variable of // definition, this variable storage is measured the numerical value of temperature.
Float rh_lin; A floating type variable of // definition.
Float rh_true; The temporary actual humidity of floating type of // definition is worth variable.
Float t_C; The temporary actual temperature of floating type of // definition is worth variable.
T_C=t*0.01-40; // actual temperature computing formula
rh_lin=C3*rh*rh+C2*rh+C1;
Rh_true=(t_C-25) * (T1+T2*rh)+rh_lin; // actual temperature value obtains computing formula.
Equalized temperature principle: by the same upper temperature limit of setting of temperature value of current collection, lower limit compares, if this value surpasses the higher limit of setting, now master control borad sends a refrigeration command frame (every day, command frame was all the agreement that master control borad and air-conditioning control panel set) to air-conditioning control panel, air-conditioning control panel feeds back to master control borad after receiving this order immediately, and air conditioner starts to support the chamber processing of freezing to marking, after receiving feedback signal, to air-conditioning control panel, there is cooling order immediately in master control borad, air-conditioning control panel feeds back to master control borad after receiving this order immediately, and air conditioner starts to support the chamber processing of lowering the temperature to marking.If this value is lower than the lower limit of setting, now master control borad sends one and heats command frame to air-conditioning control panel, air-conditioning control panel feeds back to master control borad after receiving this order immediately, and air conditioner starts to heat processing to marking foster chamber, after receiving feedback signal, to air-conditioning control panel, there is the order that heats up immediately in master control borad, air-conditioning control panel feeds back to master control borad after receiving this order immediately, and air conditioner starts to carry out hyperthermic treatment to marking foster chamber.If master control borad now sends shutdown command immediately to air-conditioning control panel within the normal range of the temperature value of current collection in setting, air-conditioning control panel feeds back a shutdown command immediately will turn off air conditioner to master control borad simultaneously.The temperature of so can balance mark supporting chamber is for a long time within normal range and extend serviceable life of air conditioner." equalized temperature schematic diagram " as shown in figure 12, the process flow diagram of equalized temperature as shown in figure 13.
Ultrasonic humidifying principle: the humidity value that gathers current humidity value and setting compares, if the humidity value gathering is higher than setting value, closes ultrasonic humidifier.If automatically start ultrasonic humidifier lower than setting value, to marking foster chamber, add wet process.Be humidity control flow chart as shown in figure 14.
