The utility model discloses a fan disc with independent fresh air, which comprises a shell 1 and a heat exchanger 2 arranged in the shell 1, wherein the heat exchanger 2 can be a fin type heat exchanger and is used for refrigerating or heating return air entering the shell 1. A separation assembly is arranged in the shell 1, and the separation assembly separates the inner cavity of the shell 1 into a return air cavity 11 and a fresh air cavity 12 which are mutually independent. The return air cavity 11 is communicated with a return air inlet 13 and a first air outlet 14 which are formed in the shell 1, the fresh air cavity 12 is communicated with a fresh air outlet and a second air outlet 15 which are formed in the shell 1, and the heat exchanger 2 is arranged in the return air cavity 11.

The air return opening 13 is formed in the top of the shell 1, so that indoor air enters the air disc from the top air return opening 13 after the air disc is installed. The first air outlet 14 and the second air outlet 15 are both arranged on the same side of the shell 1, so that negative pressure is conveniently applied to the air outlets, and return air is driven to flow out from the air outlets after passing through the heat exchanger 2. The fresh air port is communicated with outdoor air, an air valve 4 is arranged in the fresh air port, and the air valve 4 is driven by a controller. When the air valve 4 is opened, outdoor air flows into the fresh air cavity 12 under the drive of the negative pressure of the second air outlet 15 and is directly blown out from the second air outlet 15; when the damper 4 is closed, the outdoor air is isolated from the fresh air chamber 12 and cannot flow to the second air outlet 15 through the fresh air chamber 12. The position of the air valve 4 can be designed according to practical situations.

The return air inlet 13 is internally provided with a grid 5 and a filter screen 6 from outside to inside. The grid 5 plays a supporting role in the trampling process of a user, prevents damage to the inside of the wind disc, and simultaneously can prevent sundries with larger volume from falling into the cavity. The filter screen 6 is used for preventing impurities with smaller volume from falling into the cavity, such as dust, sand, hair and the like.

The inside of the shell 1 is provided with a water receiving disc 7, and the heat exchanger 2 is erected above the water receiving disc 7, so that condensed water generated in the heat exchange process drops into the water receiving disc 7, and is discharged in time. The separation assembly comprises a first supporting plate 31, the first supporting plate 31 is inserted into the water receiving disc 7 or integrally formed with the water receiving disc 7, the first supporting plate 31 separates the return air cavity 11 and the fresh air cavity 12, and the heat exchanger 2 is erected on the first supporting plate 31.

The shell 1 is also provided with a second bearing plate 32, and two ends of the heat exchanger 2 are respectively connected with the first bearing plate 31 and the second bearing plate 32. The two ends of the heat exchanger 2 are provided with wind shields 21, the first bearing plate 31 and the second bearing plate 32 are provided with limiting grooves, and the wind shields 21 are embedded in the limiting grooves. In this embodiment, since the heat exchanger 2 heats or cools the return air by the heated or cooled water flow, the wind guard 21 is further provided with a plurality of through holes for penetrating the pipeline of the heat exchanger 2.

The water pan 7, the first support plate 31 and the second support plate 32 are made of EPP foam material. EPP material does not have thermal conductivity, so cold bridge transmission is isolated, and energy efficiency loss of the whole machine is avoided. The water pan 7, the first supporting plate 31 and the second supporting plate 32 are formed by using foam XPS (XPS) film, so that the smooth degree of the water pan 7 and the supporting plate is ensured, and the plugging fit is tighter.

The separation assembly further comprises a separation plate 33, and the separation plate 33 is embedded in the return air inlet 13 and corresponds to the fresh air cavity 12. The partition 33 is attached to the casing 1, and the suspension end of the partition is connected to the first supporting plate 31, so that a side of the return air chamber 11, which is close to the return air inlet 13, extends toward the fresh air chamber 12. The gaps between the peripheries of the wind shield 21, the first bearing plate 31 and the partition plate 33 and the shell 1 are filled with sealing sponge, so that the occurrence of wind cross between the fresh air cavity 12 and the return air cavity 11 is further avoided. The sealing sponge is made of PU sponge materials.

When the indoor air is required to be refrigerated or heated, negative pressure is formed at the first air outlet and the second air outlet by an external fan, so that the indoor air is sucked in through the air return opening. The sucked indoor air is blown out from the first air outlet after being heated or cooled by the heat exchanger and finally is sent back to the room, and the circulation is performed, so that the rapid temperature rise or temperature reduction of the indoor air is realized, the time required by heat exchange is reduced, the energy consumption is saved, and the efficiency is reduced by preventing the introduction of fresh air.

When indoor air is turbid, outdoor fresh air needs to be introduced. At this time, the controller drives the air valve to open, and because the external fan still operates at this time, the second air outlet still has negative pressure, so that outdoor fresh air can be sucked into the fresh air cavity through the air valve and then directly blown out from the second air outlet, and finally the fresh air is sent back to the room after being mixed with indoor air outside the air disc. The air flows of the fresh air cavity and the return air cavity are not mixed in the air disc, and the influence of the temperature difference of the fresh air on the heat exchanger is avoided.

According to the air disc with the independent fresh air, indoor air enters from the top of the air disc, is subjected to heat exchange and then is discharged from the side face to form convection circulation, and fresh air is controlled through the air valve so as to regulate the indoor air quality. The structure has large air return area and can improve the air return efficiency. Meanwhile, the fresh air cavity and the return air cavity of the air disc are mutually independent, so that the full heat exchange between the return air and the heat exchanger can be ensured, and the influence of fresh air on the heat exchange efficiency is avoided.
