The selection of control law and control parameter:
Compressor control: the control of compressor generally is that actual temperature value and desired temperature that temperature-sensitive head collects are compared, the start-stop of decision compressor.Generally, the startup-shutdown temperature of refrigerating chamber is: Tk=Ts+3 ℃, Tt=Ts-3 ℃.The startup-shutdown temperature of refrigerating chamber is: Tk=Ts+1 ℃, Tt=Ts-1 ℃.
Fan electromotor control: fan electromotor is provided with for heat exchange air-flow circulation in the case; so the start-stop of fan electromotor start-stop general and compressor is synchronous; be the compressor start, fan motor runs, compressor shutdown; fan electromotor shuts down; simultaneously, the cold air in order to prevent to open the door leaks, and the start-stop of fan electromotor also is subjected to the control of door switch; promptly any one door is opened in refrigeration, the refrigerating chamber, and fan electromotor shuts down.
Defrost heater control: from fresh-keeping, energy-conservation angle, Defrost heater should be automatic sensing frost thickness, accomplished that frost then removes, but the detection of frost layer can't be accurate at present, therefore, present stage Defrost heater the general bar of control reach the way control of predetermined defrosting temperature cutoff with regularly connecting defrosting, temperature.It generally is accumulation compressor operating 9 hours that Defrost heater is connected.Defrosting finishes to be generally evaporimeter (temperature-sensitive head promptly defrosts) temperature and reaches 6 ℃.The power of Defrost heater is generally 145 ~ 160W.
Because for refrigerator; Defrost heater is a heater, if Defrost heater can not effectively turn-off the danger that causes fire, therefore; in Defrost heater control, increased temperature fuse protection and the software judgement usually safeguard measures such as protection of the longest heat time heating time.
Temperature fuse is out of control when Defrost heater, makes evaporator temperature reach 72 ℃ of fusing automatically, cuts off heating circuit.
The control of Defrost heater heating maximum duration generally is when the continuous time of connecting of accumulation heater reaches 1 hour in software, to cut off the heater loop automatically.
Gate light control: gate light generally is a refrigerating chamber illumination usefulness, so be controlled by the refrigerating-chamber door switch.Frost-free refrigerator illuminating lamp power is generally 10W.
Duct insert heater control: duct insert heater (backwind tube heater strip among the figure and return air inlet heater strip) designs in order to prevent the air channel from freezing the obstruction air channel, and duct insert heater works asynchronously with Defrost heater.
MOD control: the switching of MOD is determined by the refrigerating chamber temperature-sensitive head.When temperature of refrigerating chamber hangs down to break point, close MOD, when temperature of refrigerating chamber exceeds the start point, open MOD.
Pulsating pump and from the ice Electric Machine Control: this part is automatic ice maker part (principle slightly)
In conjunction with Fig. 7-Fig. 9, the course of work of monitor network provided by the invention is illustrated.
Carrying out refrigerator condition monitoring, process diagnosis and maintenance can realize by comprising these three links of intelligent refrigerator, external microcomputer and diagnosis and maintenance centre's computer, wherein, intelligent refrigerator is connected by the serial communication circuit with external microcomputer, and microcomputer is connected by the Internet with maintenance centre's computer with diagnosis.Now as follows: A) intelligent refrigerator to the function declaration of each link
