And at least one plasma generation module 103 positioned in the housing 101 for releasing positive and negative ions into the air duct 102. It will be understood by those skilled in the art that only a single plasma generation module 103 is illustrated in fig. 1 and 2, but the plasma fan coil 100 may include a plurality of plasma generation modules 103, and these plasma generation modules 103 may be disposed on the inner side wall of the housing 101, or may be disposed alongside a plurality of fans 104, or the plasma generation modules 103 may be disposed on the inner side wall of the housing 101 at the same time, and may be disposed alongside a plurality of fans 104.

In addition, when the plasma fan 104 coil works, indoor air continuously enters the air duct 102 from the air inlet 1021 for sterilization, and purified air is continuously discharged into the room from the air outlet 1022.

In addition, suspended particles exist in the air entering the air duct 102 from the air inlet 1021, and the suspended particles are mutually attracted by respectively adsorbing positive ions and negative ions generated by the plasma generation module 104, so that the suspended particles are favorably gathered into large particles from small particles.

It will be appreciated by those skilled in the art that in operation of plasma fan coil 100, a wind tunnel 102 is formed within housing 101. accordingly, housing 101 may have a chamber therein, which may have various shapes, as shown in fig. 1 and 2. housing 101 may comprise a rectangular chamber extending in a longitudinal direction (as shown in the x-direction in fig. 1 and 2).

In some embodiments, the plasma generation module 103 is located upstream of the fan 104 on the air path. When the plasma fan coil 100 is operated, the fan 104 located downstream of the air passage can be sterilized when the positive ions and negative ions generated by the plasma generation module 103 move in the air passage 102.

Under the same voltage, the efficiency of generating ions by the micro-nano conductive fiber clusters is far higher than that of a single needle point electrode or a DBD flat electrode. The micro-nano conductive fiber cluster discharges through the tips formed by a large number of fibers to form an enough discharge channel, so that the ion generation efficiency is improved. Further, in the present embodiment, the operating voltage V of the ion discharger_OPMay be below corona discharge threshold V_S. Therefore, harmful byproducts such as ultraviolet rays, ozone, nitrogen oxides and the like generated due to overhigh voltage can be relieved and even avoided, and the device is more environment-friendly and safer.

In some embodiments, the power supply or power interface may provide a high voltage constant current power supply, e.g., a voltage above 2000 volts, to power the positive ion release array 1031 and the negative ion release array 1032 to efficiently ignite plasma. In some embodiments, the power source or power interface may include a battery, such as a rechargeable battery.

Fig. 5 illustrates a schematic diagram of the operation of a plasma generation device according to some embodiments of the present disclosure. When the plasma generation module 103 works, the power supply or the power interface supplies power to the positive ion releaser array 1031 and the negative ion releaser array 1032, and the positive ion releaser and the negative ion releaser are excited to respectively release positive ions and negative ions. For example, the micro-nano conductive fiber cluster of the positive ion releaser is excited to generate electricity to release positive ions, and the micro-nano conductive fiber cluster of the negative ion releaser is excited to generate electricity to release negative ions.

As shown in fig. 5, the positive ion releaser of the positive ion releaser array 1031 generates a large amount of positive ions, and the negative ion releaser of the negative ion releaser array 1032 generates a large amount of negative ions. The positive and negative ions are released into the plasma processing region and mixed with each other to form a high concentration plasma, for example, the average ion concentration may be not less than 10⁷/cm³. For example, a gas stream may flow through the plasma processing region, as indicated by the arrows in fig. 5, and positive and negative ions may be driven by the gas stream to move and mix in the plasma processing region. The gas flow may comprise various gas flows, such as an air flow. In the plasma treatment zone, the plasma may treat the gas stream, such as to sterilize, disinfect, etc.

As shown in fig. 5, the positive ion releaser array 1031 and the negative ion releaser array 1032 may be oppositely arranged. For example, the discharge tips of the positive ion releasers on the positive ion releaser array 1031 may be directed to the discharge tips of the negative ion releasers on the negative ion releaser array 1032. Between the positive ion releaser array 1031 and the negative ion releaser array 1032, a plasma processing region may be formed. In some embodiments, the distance between the positive ion releaser array 1031 and the negative ion releaser array 1032 may be in the range of 40mm-1500 mm.

In some embodiments, the positive ion releaser array 1031 and the negative ion releaser array 1032 can be arranged in other arrangements, such as at least one of side-by-side arrangement, spaced arrangement, staggered arrangement, angled arrangement, back-to-back arrangement or stacked arrangement. Wherein the angled arrangement means that the orientations of the normal directions of the positive ion releaser array 1031 and the negative ion releaser array 1032 form an included angle of more than 0 ° and less than 180 °. For example, the positive ion releaser array 1031 and the negative ion releaser array 1032 may be arranged at intervals, oriented substantially the same, forming a plasma processing region in the direction of orientation. Positive ion releaser array 1031 and negative ion releaser array 1032 are spaced a distance apart from each other which helps to prevent premature, excessive annihilation of positive and negative ions and increase plasma concentration in the plasma processing region. Positive ion releaser array 1031 and negative ion releaser array 1032 may be arranged at an angle, oriented to form an included angle, so as to prevent premature, excessive annihilation of positive and negative ions.

The positive and negative ions are mixed with each other and diffused with the air flow to the whole air passage to form a high-concentration plasma treatment region, for example, the average ion concentration may be not less than 10⁷/cm³Therefore, a plasma environment is effectively formed, the energy generated by the mutual collision and annihilation of the positive ions and the negative ions can decompose germs in the air, a sterilization effect is achieved, the breeding and infection of the germs are reduced, and meanwhile, a large amount of free radicals such as OH, O and the like, singlet oxygen and the like excited by the plasma generation module 103 are used for decomposing pollutants. In addition, when the plasma generation module 103 works, harmful byproducts such as ozone, ultraviolet rays and nitrogen oxides are not generated, consumables such as chemical reagents and antibiotics are not used, and the plasma generation module has the characteristics of environmental protection.

In some embodiments, the plasma generation module 103 further comprises: an ion barrier 1035 (shown in fig. 4) is located between the positive ion releaser array 1031 and the negative ion releaser array 1032.

The ion barrier 1035 has an insulating property, and the ion barrier 1035 can weaken the influence of the positive and negative electric fields of the power supply on part of positive and negative ions, and reduce the probability of the ions moving towards the opposite electrode. Meanwhile, as the positive and negative ions cannot pass through the ion barrier 1035, the motion track of the compounding of the positive and negative ions when meeting is correspondingly prolonged, the formation of ion wind is hindered, and the probability of the compounding of the positive and negative ions in advance can be reduced.

In some embodiments, the ion barrier 1035 extends in the longitudinal direction of the barrier between the positive and negative

ion release arrays

1031, 1032, and the transverse cross-section of the ion barrier 1035 is triangular, rectangular, trapezoidal, or wedge-shaped.

In some embodiments, the height of ion barrier 1035 is greater than the height of positive ion releaser array 1031 and negative ion releaser array 1032. The height of the ion barrier 1035 can be set according to the actual installation environment, but is not lower than the height of the positive and negative ion releaser, and is in the range of 5mm to 100 mm.

In some embodiments, the plasma generation module 103 can also include a housing 1033 (shown in fig. 4). The housing 1033 may have various shapes. For example, the housing 1033 may have an upper surface, and the positive ion releaser array 1031 and the negative ion releaser array 1032 may be provided at intervals on the upper surface of the housing 1033. It will be appreciated by those skilled in the art that other arrangements of the positive ion releaser array 1031 and the negative ion releaser array 1032 may be employed.

In some embodiments, the housing 1033 further includes a plurality of support portions 1034 protruding from a sidewall of the housing 1033, the support portions 1034 being provided with screw holes for mounting the plasma generation module 103 or magnets 106 for attaching the plasma generation device 103 thereto.

In some embodiments, the housing 1033 can also include other mounting structures. Fig. 6 illustrates a partial schematic view at a in fig. 2 according to some embodiments of the present disclosure. As shown in fig. 6, in some embodiments, the housing 1033 further comprises one or more magnets 106 disposed on a surface or at corners of the housing 1033 for adsorptive mounting of the plasma generation module. For example, as shown in fig. 6, the magnet 106 is used to fix the plasma generation module 103 to the inner side wall of the housing 101. Specifically, the magnet 106 is located at a corner of the housing 1033 of the plasma generation module 103.

In some embodiments, plasma fan coil 100 includes: a screen 107 (shown in fig. 3) located at the air inlet 1021. The filter screen 107 can effectively prevent external dust from entering the air duct 102, and ensure the cleanness inside the air duct 102, so that the positive ion releaser array 1031 and the negative ion releaser array 1032 of the plasma generation module 103 do not stop working due to being contaminated by excessive dust, and the fan 104 is kept clean.

In addition, when the fan 104 works, the air sucked into the air inlet 1021 from the indoor space carries the annihilated positive and negative ions, and the annihilated positive and negative ions can kill bacteria in the filter screen 107 when passing through the filter screen 107, so that secondary pollution is avoided.

Have the suspended particles in the indoor air, suspended particles is because of adsorbing positive ion and anion respectively and inter attraction, gathers into the large granule by the tiny particle to when the room air got into wind channel 102 through income wind gap 1021, the large granule of gathering can be intercepted by the filter screen 107 of income wind gap 1021 department, improves the filtering efficiency of large granule dust, reduces indoor dust grade fast. Therefore, in the process of purifying indoor air in a circulating reciprocating manner by the plasma fan coil 100, the filter screen 107 and the plasma generation module 103 are used in a matching manner, so that the interception efficiency of the filter screen 107 can be effectively improved while the grade of the filter screen adopted by the filter screen 107 is reduced, the effect of purifying air is achieved, the air volume loss is reduced, the energy consumption of the fan 104 is reduced, and the effects of energy conservation and environmental protection are achieved.

In some embodiments, the screen 107 comprises a primary screen, a medium-efficiency screen, or a high-efficiency screen.

In some embodiments, the plasma fan coil 100 further comprises a pneumatic switch in the wind tunnel 102, connected to at least one plasma generation module 103, for controlling the switching of the plasma generation module 103 based on the airflow.

When the fan 104 works, the airflow passes through the air duct 102, and when the pneumatic switch 108 monitors the airflow in the air duct 102, the plasma generation module 103 is turned on. Therefore, when the fan 104 is in an operating state, the plasma generation module 103 is also in an operating state, so that the air discharged into the room from the air outlet 1022 is always sterilized and purified.

In some embodiments, the plasma fan coil 100 further includes a cold heat exchanger 109 (shown in fig. 3) located upstream of the air outlet 1022.

The air in the air duct 102 is heated or cooled when passing through the heat exchanger 109, and the heated or cooled air enters the room through the air outlet 1022, thereby achieving the effect of adjusting the indoor temperature; further, since the heat exchanger 109 is located downstream of the plasma generation module 103 on the air passage, the heat exchanger 109 can be sterilized when positive ions and negative ions generated by the plasma generation module 103 move through the air passage 102.

In some embodiments, as shown in fig. 3, the heat exchanger 109 is also located downstream of the fan 104 in the air path. The cold-heat exchanger 109 is located at the downstream of the fan 104 and is far away from the plasma generation device 103, so that the working environment temperature of the plasma generation device 103 is not easily affected by the cold-heat exchanger 109, and the service life of the plasma generation device 103 is prolonged.

It should be understood that the described embodiments of the present disclosure are exemplary embodiments only, and are not to be construed as limiting the present disclosure. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present disclosure should fall within the protection scope of the present disclosure.
