The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator in the present application. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

If the floater does not continuously float after reaching the first magnetic reed switch, but the water level in the water storage tank drops along with the continuous work of the drainage pump, the floater 100 drops along with the water level, the first magnetic reed switch is closed, the receiving ends FS1-IO1 of the first monitoring chip are in an ON state, and the control module controls the drainage pump to be closed after the time delay T2.
If the floater 100 does not continuously float after reaching the second magnetic reed switch, but the water level in the water storage tank drops along with the continuous work of the drainage pump, the floater 100 drops along with the water level, the second magnetic reed switch is closed, the receiving ends FS2-IO2 of the second monitoring chip are in an ON state, the floater 100 continuously drops until the first magnetic reed switch is closed, the receiving ends FS1-IO1 of the first monitoring chip are in an ON state, and the control module controls the drainage pump to be closed and starts the unit after the time delay T2.
And finally, the control module continuously monitors the water level signal in real time.
As shown in fig. 1, the present invention can be extended to n reed switches, the nth reed switch can send the nth water level signal FSn, and the control module can receive the signal of the receiving end FSn-IOn of the monitoring chip of the nth electronic control module.
