The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. 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.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner serves as a heater in a heating mode when the indoor heat exchanger serves as a condenser, and serves as a cooler in a cooling mode when the indoor heat exchanger serves as an evaporator.
Fig. 2 shows a circuit configuration of an air conditioner 1, and the air conditioner 1 includes a refrigerant circuit 10, and is capable of executing a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit 10. The indoor unit 3 and the outdoor unit 2 are connected by a connecting pipe 4 to form a refrigerant circuit 10 in which a refrigerant circulates. The refrigerant circuit 10 includes a compressor 11, an outdoor heat exchanger 13, an expansion valve 14, an accumulator 15, and an indoor heat exchanger 16. Among them, the indoor heat exchanger 16 and the outdoor heat exchanger 13 operate as a condenser or an evaporator. The compressor 11 sucks the refrigerant from the suction port, and discharges the refrigerant compressed therein to the indoor heat exchanger 16 from the discharge port. The compressor 11 is an inverter compressor with variable capacity that performs rotational speed control by an inverter, and the four-way valve 12 switches between heating and cooling.
The outdoor heat exchanger 13 has a first inlet and a second outlet for allowing the refrigerant to flow between the refrigerant and the suction port of the compressor 11 through the accumulator 15, and the refrigerant flows between the refrigerant and the expansion valve 14. The outdoor heat exchanger 13 exchanges heat between the outdoor air and the refrigerant flowing through a heat transfer pipe (not shown) connected between the second inlet and the first inlet of the outdoor heat exchanger 13.
The expansion valve 14 is disposed between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 has a function of expanding and decompressing the refrigerant flowing between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 is configured to be capable of changing the opening degree, and by decreasing the opening degree, the flow path resistance of the refrigerant passing through the expansion valve 14 increases, and by increasing the opening degree, the flow path resistance of the refrigerant passing through the expansion valve 14 decreases. The expansion valve 14 expands and reduces the pressure of the refrigerant flowing from the indoor heat exchanger 16 to the outdoor heat exchanger 13 during the heating operation. Further, even if the states of other devices installed in the refrigerant circuit 10 do not change, when the opening degree of the expansion valve 14 changes, the flow rate of the refrigerant flowing in the refrigerant circuit 10 changes.
The indoor heat exchanger 16 has a second inlet and outlet for allowing the liquid refrigerant to flow between the expansion valve 14 and the indoor heat exchanger, and has a first inlet and outlet for allowing the gas refrigerant to flow between the compressor 11 and the discharge port. The indoor heat exchanger 16 exchanges heat between the refrigerant flowing through the heat transfer pipe connected between the second inlet and the first inlet and the second outlet of the indoor heat exchanger 16 and the indoor air.
An accumulator 15 is disposed between the outdoor heat exchanger 13 and the suction port of the compressor 11. In the liquid receiver 15, the refrigerant flowing from the outdoor heat exchanger 13 to the compressor 11 is separated into a gas refrigerant and a liquid refrigerant. Then, the gas refrigerant is mainly supplied from the accumulator 15 to the suction port of the compressor 11.
The outdoor unit 2 further includes an outdoor fan 21, and the outdoor fan 21 generates an airflow of outdoor air passing through the outdoor heat exchanger 13 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the outdoor air. The outdoor fan 21 is driven by an outdoor fan motor 21A capable of changing the rotation speed. The indoor unit 3 further includes an indoor fan 31, and the indoor fan 31 generates an airflow of the indoor air passing through the indoor heat exchanger 16 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the indoor air. The indoor fan 31 is driven by an indoor fan motor 31A whose rotation speed can be changed.
In the embodiment of the invention, the controller acquires a first detection value corresponding to the concentration of particulate matters and a second detection value corresponding to the concentration of TVOC, if the first detection value is greater than a first preset starting threshold value and the second detection value is greater than a second preset starting threshold value, the IFD module is kept in the running state, and the anion module is intermittently started based on a preset intermittent period and a preset running time, so that the IFD module and the anion module are simultaneously used in the air conditioner and stably run, and the purifying and sterilizing effects are improved.

L2>1.5L1
(2) considering the influence of the wind direction, the discharging end (negative voltage) of the IFD module, the grounding end of the IFD module, and the discharging end (negative voltage) of the negative ion module are arranged in sequence along the wind direction, as shown in fig. 4.
The principle is as follows:
1) the discharge end of the IFD module generates free electrons, and PM2.5 with positive electricity is attracted and gathered and filtered by a filter screen to the grounding end of the IFD module to form a loop;
2) the discharge end of the negative ion module generates free electrons, and the components of the ionized air form negative ions which are blown to the room by wind, so that the TVOC is eliminated.
The control mode is as follows:

And then the preset operation time of the negative ion module can be determined according to the intermittence coefficient and the preset intermittence period.
By applying the technical scheme, a first detection value corresponding to the concentration of the particulate matter and a second detection value corresponding to the concentration of the TVOC are obtained, if the first detection value is greater than a first preset starting threshold value and the second detection value is greater than a second preset starting threshold value, the IFD module is kept in the running state, and the anion module is intermittently started based on a preset intermittent period and a preset running time; and the end of discharging of IFD module the earthing terminal of IFD module with the end of discharging of anion module arranges in proper order along the wind direction according to predetermineeing the distance in the air conditioner, reduced IFD module and anion module's influence each other, make IFD module and anion module compact installation and steady operation simultaneously, greatly promote the purification degerming effect.
