Background
Both the negative ion module and the IFD (Intense field dielectric, strong field dielectric) module belong to high voltage discharge, and if they operate simultaneously, the electric fields overlap or cancel each other, the following effects will occur:
(1) Electric field superposition
The discharge end of the IFD module is-12 KV, the GND end is 0V, the discharge end of the anion module is-10 KV, when two electric fields are overlapped, a local-22 KV high negative pressure end is formed, a large amount of free electrons are generated under the action of the high negative pressure end, oxygen and nitrogen in air are ionized to form ozone and nitride, the health of a user is endangered, and potential safety hazards are caused.

(3) Electronic short circuit
As shown in fig. 1: free electrons and negatively charged ions generated at the negative high-voltage discharge end of the negative ion module are absorbed by the GND end of the IFD module, so that an electronic short circuit is formed, and the following is caused:

The air conditioner in this application 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 a 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 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.
An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an 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 function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.
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 performing 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 to each other by a connection pipe 4 to form a refrigerant circuit 10 through which a refrigerant circulates. The refrigerant circuit 10 includes a compressor 11, an outdoor heat exchanger 13, an expansion valve 14, a receiver 15, and an indoor heat exchanger 16. The indoor heat exchanger 16 and the outdoor heat exchanger 13, among others, function as a condenser or an evaporator. The compressor 11 sucks in 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 of variable capacity that performs rotational speed control based on an inverter, and the four-way valve 12 switches between heating and cooling.
The outdoor heat exchanger 13 has a first inlet and outlet for passing the refrigerant between the outdoor heat exchanger and the suction port of the compressor 11 via the accumulator 15, and has a second inlet and outlet for passing the refrigerant between the outdoor heat exchanger and the expansion valve 14. The outdoor heat exchanger 13 exchanges heat between the outdoor air and the refrigerant flowing through a heat transfer tube (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 the opening degree is reduced to increase the flow resistance of the refrigerant passing through the expansion valve 14, and the opening degree is increased to decrease the flow resistance of the refrigerant passing through the expansion valve 14. The expansion valve 14 expands and decompresses the refrigerant flowing from the indoor heat exchanger 16 to the outdoor heat exchanger 13 during the heating operation. Further, even if the state of other devices mounted in the refrigerant circuit 10 does 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 a first inlet and outlet for allowing the gas refrigerant to flow between the gas refrigerant and the discharge port of the compressor 11. The indoor heat exchanger 16 exchanges heat between the indoor air and the refrigerant flowing through the heat transfer tube connected between the second inlet and the first inlet of the indoor heat exchanger 16.
A receiver 15 is disposed between the outdoor heat exchanger 13 and the suction port of the compressor 11. In the accumulator 15, the refrigerant flowing from the outdoor heat exchanger 13 to the compressor 11 is separated into a gas refrigerant and a liquid refrigerant. 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 the 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 rotational 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 indoor air and the refrigerant flowing through the heat transfer pipe. The indoor fan 31 is driven by an indoor fan motor 31A capable of changing the rotational speed.
In the embodiment of the invention, the controller acquires the first detection value corresponding to the concentration of the particulate matters and the second detection value corresponding to the concentration of the TVOC, if the first detection value is larger than the first preset starting threshold value and the second detection value is larger than the second preset starting threshold value, the IFD module is kept in an operating state, and the anion module is intermittently started based on the preset intermittent period and the preset operation time, so that the IFD module and the anion module are simultaneously used in the air conditioner and are enabled to stably operate, and the purification and sterilization effects are improved.
The present invention will be described below with reference to the mounting mode and the control mode.

L2>1.5L1
(2) In consideration of the influence of the wind direction, the discharge end (negative pressure) of the IFD module, the ground end of the IFD module, and the discharge end (negative pressure) of the negative ion module are sequentially arranged 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, attracts and gathers positively charged PM2.5, filters the free electrons through a filter screen and reaches the grounding end of the IFD module to form a loop;
2) The discharge end of the negative ion module generates free electrons, ionizes components of air to form negative ions with negative electricity, and is blown into a room by wind to eliminate TVOC.
The control mode is as follows:
preventing interaction between the IFD module and the electric field of the negative ion module, and during control, adopting an intermittent working mode, as shown in fig. 5:
in the purification mode, a first detection value corresponding to the concentration of particulate matters (such as PM 2.5) in the ambient air and a second detection value corresponding to the concentration of TVOC in the ambient air are obtained, if the first detection value is larger than a first preset starting threshold value and the second detection value is larger than a second preset starting threshold value, the IFD module is kept in an operating state, and the anion module is intermittently started based on a preset intermittent period and a preset operating duration.
The preset intermittent period (pulse width modulation PWM) may be determined according to a second detection value corresponding to the TVOC concentration and a preset relationship table, or may be determined according to a set value input by a user, where the preset relationship table is established according to a corresponding relationship between the second detection value and the preset intermittent period.
The intermittent coefficient D is the ratio of the operation duration of the negative ion module in the intermittent period to the intermittent period, the intermittent coefficient can be 0.5 or 0.25, and whether a second detection value corresponding to the TVOC concentration is larger than a preset threshold value is judged; if yes, d=0.5; if not, d=0.25. And then determining the preset operation time length of the negative ion module according to the intermittent coefficient and the preset intermittent period.
By applying the technical scheme, a first detection value corresponding to the concentration of the particulate matters and a second detection value corresponding to the concentration of the TVOC are obtained, if the first detection value is larger than a first preset starting threshold value and the second detection value is larger than a second preset starting threshold value, the IFD module is kept in an operating state, and the anion module is intermittently started based on a preset intermittent period and a preset operating time length; and the discharge end of the IFD module, the grounding end of the IFD module and the discharge end of the anion module are sequentially arranged in the air conditioner along the wind direction according to a preset distance, so that the mutual influence of the IFD module and the anion module is reduced, the IFD module and the anion module are compactly installed and stably operated at the same time, and the purification and sterilization effects are greatly improved.
Corresponding to the air conditioner in the embodiment of the present application, the embodiment of the present application further provides a control method of the air conditioner, where the method is applied to the air conditioner including a refrigerant circulation loop, a compressor, an outdoor heat exchanger, an indoor heat exchanger, a strong field dielectric IFD module, a negative ion module and a controller, as shown in fig. 6, and the method includes the following steps:

Specifically, particulate matters in the air around the air conditioner may be particulate matters such as PM2.5 or PM10, a first detection value corresponding to the concentration of the particulate matters may be obtained through a PM2.5 sensor or a PM10 sensor, a second detection value corresponding to the concentration of the TVOC may be obtained through a TVOC sensor, and if the first detection value is greater than a first preset starting threshold, the IFD module needs to be kept in an operating state to reduce the first detection value, so as to avoid the interaction between the negative ion module and the IFD module, and the negative ion module is intermittently started based on a preset intermittent period and a preset operation duration.
The discharge end of the IFD module, the grounding end of the IFD module and the discharge end of the anion module are sequentially arranged in the air conditioner along the wind direction, so that the discharge end of the IFD module generates free electrons, positively charged particles (such as PM 2.5) are attracted and gathered, filtered by a filter screen and reach the grounding end of the IFD module to form a loop, and meanwhile, the discharge end of the anion module generates free electrons, ionizes components of air to form negatively charged anions, and the negatively charged anions are blown into a room by wind to eliminate TVOC.
