referring to fig. 6, according to a conventional system configuration, the present embodiment is composed of an indoor unit, an outdoor unit, a refrigeration system and a corresponding control circuit; during refrigeration, low-pressure and low-temperature refrigerant vapor in the refrigeration system is sucked by the compressor, compressed into high-pressure and high-temperature superheated vapor and then discharged to the heat exchanger of the outdoor unit; meanwhile, outdoor air sucked by the outdoor fan flows through the outdoor heat exchanger to take away heat emitted by the refrigerant, so that high-pressure and high-temperature refrigerant vapor is condensed into high-pressure liquid. The high-pressure liquid flows into the indoor machine heat exchanger through the throttling capillary tube for pressure reduction and temperature reduction, and is evaporated under corresponding low pressure to absorb the surrounding heat; meanwhile, the indoor side fan enables indoor air to continuously enter fins of the indoor machine heat exchanger for heat exchange, and sends the cooled air after heat release to the indoor. Therefore, the indoor air and the outdoor air continuously circulate and flow, and the purpose of reducing the temperature is achieved. When heating, the heat of compression and condensation of the refrigerating system is utilized to heat the indoor air, the low-pressure and low-temperature refrigerant liquid is evaporated and absorbs heat in the evaporator, and the high-temperature and high-pressure refrigerant gas is released and condensed in the condenser. When the heat pump heats, the circulation direction of the refrigerant is changed by the four-way valve, so that an indoor unit heat exchanger serving as an evaporator during the original refrigerating work is changed into a condenser during heating, and an outdoor unit heat exchanger serving as a condenser during the original refrigerating work is changed into an evaporator during heating, therefore, the refrigerating system absorbs heat outdoors and releases heat indoors, and the purpose of heating is achieved.

The CPU senses the environment in the cabinet and the temperature change of the air outlet of the display machine through AD conversion and collection of the voltage, and therefore the voltage is used as a judgment basis for the temperature change in the control process of the display system. Wherein the ambient temperature in the cabinet is T1, and the temperature of the air outlet of the display machine is T2.

As shown in fig. 8, the voltage acquisition circuit performs high-voltage isolation and voltage division by using resistors R3, R4, R5, R7, R8, R9, R10, and R12, a signal detected by the MCU is a half-wave signal of 100HZ, which is filtered by R6, C2, R11, and C2 in different half cycles, and then input to the AD port of the CPU by D1 clamping, and converted to obtain a voltage value, and the program is used for control and protection after being processed, and is used as a basis for power display on the display screen;

as shown in fig. 8, the current collection circuit collects the input side current through the sampling resistor RS1, and the current is supplied to the AD port of the CPU through the operational amplifier, and the program is processed for control, protection, and display.

Reference voltage

In response to the input current of 0A,

setting the gain of RS1 as G1; if the operational amplifier gain is G2, the system outputs V0= (G1 XG 2 XI 0) + Vref;

the CPU calculates the input current I0 through a formula according to the detected V0 value.

As shown in fig. 9, the level switch acquisition circuit detects the level of the water receiving tray through one or more level switches disposed in the water receiving tray, and combines the ambient temperature in the cabinet as a basis for determining the control of the water pump, the water receiving tray heater, and the atomizer.
