News Reading | Current Location: internal structure Home >> News >> Simmel / News supermarket fruit fresh cabinet, introduced the internal structure of the supermarket fruit fresh cabinet introduction; fruit fresh cabinet cabinet air conditioner in supermarket heating operation, also need to increase the defrosting time to time heating some fruit, to make the air conditioner defrosting operation, must meet the following two conditions. Supermarket fruit fresh cabinet remote control signal transmitter is independent of the air conditioner of the machine key switch box, it is known as a remote switch. The keypad consists of matrix switch circuit. ICl scan pulse switch box and the keyboard signal encoder input circuit constitute key commands. When you press a function key, the corresponding scan pulse through the key switch input to the ICl, ICl enable read-only memory within the corresponding address is read out to produce the corresponding instruction code, and then converted by the instruction into a binary encoder Yu-coded instructions. The coded instructions supermarket fruit fresh cabinet instruction output from the encoder to the encoder modulator to form a modulated signal. Modulated signal through a buffer stage to encourage control, infrared signal from the driver stage VTI, VT2 composition enlarged enough power to drive an infrared light emitting diode emits modulated command signal. Meanwhile, supermarket fruit fresh cabinet cabinet air conditioner control system supermarket in a more comprehensive protection circuitry. When Mei through thermal relay current exceeds a predetermined value, FR normally closed contacts will jump open, normally open contact sticking. And when the system pressure is too high, the high-pressure controller P contacts will jump. Therefore, if any of the above situation, it can make J2 relay coil is energized. J2 action eyelashes S line voltage is zero, then the air conditioner does not work, there will be failures prompted the panel supermarket fruit fresh cabinet display.
