Further, the radiuses of the impellers of the centrifugal fans (111, 121) of the first air supply assembly 110 and the second air supply assembly 120 may be the same or different, and the air supply capacities of the first air supply assembly 110 and the second air supply assembly 120 are not required, and may be the same or different. The second air supply assembly 120 may be an alternative air supply assembly, when the air conditioner is started up in an initial stage, the indoor temperature needs to be quickly lowered or raised, a large air volume circulation is needed, the second air supply assembly 120 may be turned on to increase the air volume of the indoor unit 10, so that the indoor temperature quickly reaches the preset temperature of the user, when the indoor temperature is stable, the second air supply assembly 120 may not be operated, and only the first air supply assembly 110 is operated to maintain the indoor temperature stable, so that the air supply capacity of the second air supply assembly 120 is not required to be the same as the air supply capacity of the first air supply assembly 110.
Or, when the indoor air quality is seriously polluted and the oxygen content is low, and the fresh air device 200 needs to be opened, the second air supply assembly 120 can be started to operate, so that the function of auxiliary air supply is achieved, the indoor air is rapidly updated by the outdoor fresh air, and the indoor air quality is rapidly recovered to a good state.
For the new trend device 200, in order to prevent that the winter from using the condition of air conditioner or heating installation for a long time, the room air is comparatively dry, is unfavorable for user healthy, the inventor is to being provided with humidification subassembly 230 in the air inlet chamber of new trend device 200 for carry out the humidification to outdoor new trend.
As shown in fig. 6 to 8, the humidifying assembly 230 includes a clip-shaped water tank 231 transversely disposed in the air inlet chamber, water is injected into the clip-shaped water tank 231, and the humidity in the air inlet chamber is increased by evaporation of water vapor, so as to increase the humidity of outdoor fresh air entering the air inlet chamber.

The aperture of the water-absorbing and water-retaining material is 1-2 cm, and the water-absorbing and water-retaining material is used for absorbing water in the square water tank 231 to the ventilating grid 232 to humidify outdoor fresh air. Preferably, the aperture of the water-absorbing and water-retaining material is 2mm, so that the humidity at the ventilating grid 232 is ensured, the outdoor fresh air is fully humidified, and the outdoor fresh air stably and smoothly passes through the ventilating grid 232. If the aperture is less than 1mm, a large amount of fresh outdoor air can be collected at the ventilation grating 232, and when the pressure reaches a certain degree, the connection relationship between the water-absorbing and water-retaining material and the clip-shaped water tank 231 is damaged. When the pore diameter is larger than 2mm, the humidifying effect is not so remarkable.
Because the humidifying component is arranged in the air inlet cavity, outdoor fresh air passes through the air inlet cavity and enters the air supply cavity, the outdoor fresh air is humidified by the humidifying component, and the humidity of the outdoor fresh air entering the room is improved.

As shown in fig. 6, when the cleaning module 251 needs to be replaced or water needs to be filled into the rectangular trough 231, the user pulls out the cleaning module 251 through the pull handle 252, and replaces the cleaning module 251 or fills water into the rectangular trough 231, so that the structure is simple and the operation is convenient for the user.
In addition, there is the clearance between purification module 251 and the ventilation bars 232, and the clearance here plays the cushioning effect to outdoor new trend, can make outdoor new trend fully humidify in ventilation bars 232 department on the one hand, and on the other hand makes the even stable entering of outdoor new trend purify module 251.
The purification module 251 can purify air delivered to the room using a high electric field dielectric technology. Specifically, this purification module 251 is IFD purifier, and IFD is a dust removal technique, for the most advanced among the present dust removal technique, the most efficient technique, and the effectivity is extremely strong. A strong electric field with a dielectric material as a carrier is utilized. The dielectric material forms a honeycomb hollow micro-channel, the dielectric wrapping electrode slice forms a strong electric field in the channel, the strong electric field exerts huge attraction on charged particles moving in the air, only generates minimum air flow impedance, and can adsorb almost 100% of particles moving in the air, and the removal effect on particle pollutants such as PM2.5 and the like is particularly obvious. Adopt above-mentioned purification module 251, can reduce the PM2.5 granule in the air by a wide margin in the weather that the haze was abused, effectively improve the quality of sending into indoor outdoor air.
The purification module 251 can also be filtered by HEPA, which is a high-efficiency filter paper, and can filter 99% of fine particles in the air, so as to ensure that the air output by the fan module 220 is clean and avoid secondary pollution.
In order to better remove the sand and dust mixed in the outdoor fresh air, the inventor further improves the fresh air device 200, as shown in fig. 3 and 4, specifically as follows:

After entering the first air inlet cavity 211a, the fresh outdoor air changes the flow direction through the air guide plate 213 and enters the second air inlet cavity 211b through the gap.
Specifically, the air deflector 213 is on the same vertical plane with the rear wall of the blowing cavity 221; the rear wall of the blowing chamber 221 extends vertically downward to obtain the air deflection plate 213. The air deflector 213 can be formed with the air inlet cavity 211 and the air supply cavity 221 of the fresh air device 200 during the manufacturing process, so that the manufacturing process is simplified and convenient.
The air deflector 213 plays two roles in this embodiment, one is to play a role in shielding dust, so as to prevent dust in outdoor fresh air from being directly sucked into the fresh air fan 222 by the fresh air device 200 and damaging the blades of the fresh air fan; secondly, the centrifugal dust settling effect is achieved, outdoor fresh air enters the air inlet cavity 211 from the fresh air inlet pipe 212 under the action of the air deflector 213, the flowing direction is changed to form annular circulating inlet air, large granular substances can be thrown out under the centrifugal effect of the annular inlet air, the large granular substances are prevented from entering the fresh air fan 222, and the two effects jointly guarantee the effect of fresh air exchange.
In addition, the dust removal net is detachably mounted at the air inlet of the fresh air inlet pipe 212, so that dust or mosquitoes can be prevented from entering the fresh air device 200 to pollute or destroy the internal structure of the fresh air device 200, and the quality of fresh air exchanged by the fresh air device 200 is prevented from being reduced.
In the fresh air device 200, the filter assembly 240 and the purification assembly 250 are arranged, so that fresh air entering a room can be purified, especially, the air pollution is increasingly aggravated at present, the purified air is sent into the room, the quality of the indoor air is improved, and the harm of the polluted air to the body is reduced.
In addition, as mentioned above, the air intake module 210 and the fan module 220 of the fresh air device 200 of the present invention are distributed vertically, which is used for more reasonably utilizing the space inside the casing 100. Specifically, the fresh air exchange indoor unit 10 further includes an electrical box 140, as shown in fig. 3, the electrical box 140 is disposed at an upper portion of the fresh air device 200, and in order to effectively utilize the limited space inside the casing 100 of the indoor unit 10, the upper portion of the air supply cavity 221 includes a horizontal section 221a extending backward from the front portion of the casing 100 and an inclined section 221b extending along the horizontal section 221a and continuously inclining upward toward the air outlet 202 of the volute 223 of the fresh air blower 222; the electrical box 140 is located on the inclined section 221 b.
Generally, the electrical boxes 140 are transversely distributed inside the casing 100, however, in the present invention, the electrical boxes 140 are creatively arranged in an inclined manner and fixedly mounted on the inclined section 221b of the air supply cavity 221 of the fresh air device 200, the air supply cavity 221 further plays a role of a bracket, which reduces the original fixing structure of the electrical boxes 140, and makes more space inside the casing 100 used for air circulation, therefore, the fresh air exchange indoor unit 10 provided by the present invention not only has enough power to drive the outdoor fresh air to flow, but also has enough space to make the outdoor fresh air enter the indoor unit 10.
Moreover, the electrical box 140 is obliquely arranged, the interior of the electrical box 140 faces the front part of the shell 100, and the wiring groove of the electrical box 140 is close to the front upright post of the cabinet air conditioner, so that the wiring and the arranging are convenient to maintain, the production efficiency of a production line is improved, and the inspection and the maintenance of after-sales personnel are also convenient.
The fresh air device 200 in each of the above embodiments can be operated independently of the heating or cooling operation of the indoor unit 10, and can also be operated synchronously with the heating and cooling operation of the indoor unit 10.
In the fresh air exchange indoor unit 10 of the air conditioner of the present invention, the fresh air device 200 may be installed inside the indoor unit 10, integrated with the indoor unit 10, or installed outside the indoor unit 10. No matter the installation state of any form, all can reduce the cost of using the new trend system among the prior art by a wide margin, and the noise is low, has better user experience.
In the following description, the terms "front", "back", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", "longitudinal", "left and right", and the like, are used in the orientations and positional relationships indicated in the drawings, which are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
