DETAILED DESCRIPTION

[0020] The utility model is further described below through an implementation method. As shown in the accompanying drawings, the following description is only an exemplary explanation of the structure of the constant air volume environmental control integrated machine. Those skilled in the art can make further improvements on the structure based on the following explanation. The scope of protection of this patent shall be based on the scope recorded in the claims.

[0021] Embodiment 1:

[0022] A constant air volume environmental control integrated machine, comprising a square box 1, the outer wall of the box 1 is provided with an indoor circulation port 12 and an indoor return air port 13, an outdoor air inlet 15, an outdoor exhaust port 16, an indoor air supply port 17 and a controller 14. The utility model can achieve a one-to-two heating or cooling effect, so Figure 3 As shown, there are two indoor air supply outlets 17 which are arranged at intervals. The two indoor air supply outlets 17 can respectively fix two outlet ends to supply air to different areas.

[0023] The box body 1 is provided with an evaporator 2 and a terminal filter 3, and the evaporator 2 and the terminal filter 3 are arranged inside the indoor air outlet 17; both are used for final filtering and temperature adjustment during indoor air supply. In this embodiment, the evaporator 2 and the terminal filter 3 vertically penetrate the entire box body 1.

[0024] like Figure 1As shown, a single high-power full-heat core 6 is provided in the box 1, and the box 1 is divided into an indoor air supply bin 4, an outdoor air exhaust bin 7 and an outdoor air inlet bin 8 by connecting the single high-power full-heat core 6 in series and cooperating with a plurality of partitions 18.

[0025] The indoor return air port 13 is connected to the high-power full-heat core 6 and then connected to the outdoor exhaust bin 7 through the regulating valve 5, and the indoor air is discharged to the outside through the outdoor exhaust fan 71.

[0026] The outdoor air inlet bin 8 is connected to a single high-power full-heat core 6 and then connected to the indoor air supply bin 4 through a regulating valve 5. An indoor air supply fan 41 is provided in the indoor air supply bin 4. The outdoor air flow is introduced into the terminal filter 3 through the indoor air supply fan 41. The terminal filter 3 is fixed in the filter bin 31.

[0027] Furthermore, an indoor gas filter module 42 is provided in the box body 1 corresponding to the indoor circulation port 12 and the indoor return air port 13, and the indoor recovered gas is uniformly filtered through the indoor gas filter module 42. During actual operation, in order to prevent the airflow from flowing inside the indoor gas filter module 42, the utility model is provided with a spacer on the indoor gas filter module 42, and the indoor gas filter module 42 is divided into two by the spacer and independently provided corresponding to the indoor circulation port 12 and the indoor return air port 13.

[0028] Furthermore, an outdoor air filter module 81 is provided in the box body 1 corresponding to the outdoor air inlet 15, and the outdoor air is primarily filtered by the outdoor air filter module 81.

[0029] The utility model is provided with a top cover 10 and a bottom cover on the box body 1, and a plurality of inspection ports are provided on the top cover 10, namely, a terminal filter inspection port 32, an indoor filter inspection port 43, and an outdoor filter inspection port 82; the above inspection ports are openable, and are respectively provided corresponding to the terminal filter 3, the indoor gas filter module 42, and the outdoor gas filter module 81. External personnel can replace and maintain the internal filter module through each inspection port.

[0030] When the utility model is used, Figure 5 As shown, fresh air enters from the outdoor air inlet 15 and undergoes primary filtration through the outdoor gas filter module 81, then passes through the high-power full-heat core 6 for heat exchange, passes through the regulating valve 5, and then enters the indoor air supply bin 4, and then is pressurized by the indoor air supply fan 41, and undergoes secondary filtration through the terminal filter 3, and then enters the room through the indoor air supply port 17 after the temperature is adjusted by the evaporator 2.

[0031] The indoor air enters the indoor gas filter module 42 through the indoor return air port 13 for filtration, and then exchanges heat between the indoor gas and the outdoor fresh air through the high-power full-heat core 6, and then enters the outdoor exhaust bin 7, is pressurized by the outdoor exhaust fan 71, and is discharged to the outside through the outdoor exhaust port 16.

[0032] In the above process, only the indoor air supply fan 41 and the external exhaust fan 71 are used for internal and external air supply, which effectively reduces energy consumption and noise. During the air supply process, the fresh air volume is adjusted by the regulating valve 5. This design can adapt to different working conditions. In addition, all the above structures adopt mechanical structure design, which is stable, efficient and has a low failure rate.

[0033] When the utility model performs indoor air circulation, after the indoor circulation port 12 and the indoor air supply fan 41 are opened, the airflow passes through the indoor gas filter module 42 for primary filtration, then enters the indoor air supply bin 4 for pressurization by the indoor air supply fan 41, passes through the terminal filter 3 for secondary filtration, and then is temperature adjusted by the evaporator 2 before being sent into the room through the indoor air supply port 17 to complete the indoor circulation.

[0034] Furthermore, since this type of constant air volume environmental control integrated machine is supported by only four hanging rods during operation, the high-power fan in the box body 1 will vibrate during operation. In order to prevent this vibration from being transmitted to the outside and causing resonance or noise increase, the utility model improves the hanging rod pulling structure as follows: A hanging rod seat 11 is provided on the side wall of the box body 1, such as Figure 4 As shown, the hanging rod seat 11 includes a mounting plate 111 and a hanging plate 112. The mounting plate 111 and the hanging plate 112 are bent at right angles, and end baffles 114 are respectively arranged at the ends of the two. The outer end of the hanging plate 112 is provided with a vertical edge 115, and the outer side blocking is achieved by the vertical edge 115; the middle part of the hanging plate 112 is provided with a hanging groove 113.

[0035] When the hanging rod seat 11 is hoisted and fixed, elastic blocks are arranged on the upper and lower parts of the hanging plate 112, and a tension rod runs through the elastic block and the hanging groove 113. The end baffle 114 and the vertical edge 115 form a vertical blocking area. The vertical blocking area is used to horizontally constrain the elastic block located at the upper part to prevent the elastic block from moving horizontally. When the equipment is running, the vibration of the equipment will be absorbed by the elastic block to avoid the transmission of noise and vibration.
