from RY1 to RY2…RY9 etc, which are nine relays and driver ICULN2003; another route becomes
stable 5V after 7812 regulator, and becomes single-chip, to supply electricity to LED
or LCD, or boozer etc.
Buttons, LED or LCD is a window of man-machine inter-action. The work status of machine
can be changed through buttons, LED or LCD indicates real-time work status of machine.
If remote control mode, the receiver of RC receive or send order or signal, and then pass
them to the single-chip. The surface temperature of evaporator is transferred to
single-chip through an evaporator sensor. Water level sensor transmit water level
information to the single-chip. All these signals pass to the single-chip, and then
analyzed and processed and the single-chip send all kinds of orders and control the on-off
status of all relays through driver ICULN2003.The whole machine works well under the
coordination of the single-chip.
