Those skilled in the art can make further improvements in the structure based on the following explanation. The protection scope of this patent shall be subject to the scope recorded in the claims.

[0022] Example 1:

[0023] A dual total heat environmental control integrated machine, as shown in the drawings, includes a square box body 1. The outer wall of the box body 1 is provided with an indoor circulation port 12, an indoor return air port 13, an outdoor air inlet 15, an outdoor air outlet 16, an indoor air supply port 17 and a controller 14. The present utility model can achieve the heating or cooling effect of one machine serving two, so as Figure 3 shown, the indoor air supply ports 17 are two and are arranged at intervals, and the two indoor air supply ports 17 can respectively fix the two outlet ends to supply air to different areas.

[0024] An evaporator 2 and a terminal filter 3 are arranged in the described box body 1. The evaporator 2 and the terminal filter 3 are arranged inside the indoor air supply outlet 17. The two are used for the final filtration and temperature adjustment when supplying air indoors. In this embodiment, the evaporator 2 and the terminal filter 3 longitudinally penetrate the entire interior of the box body 1.

[0025] An internal circulation chamber 42 is arranged in the box body 1. A circulation fan 43 is arranged in the internal circulation chamber 42. The internal circulation chamber 42 is connected to the evaporator 2 and the terminal filter 3 through the circulation fan 43. The internal circulation chamber 42 is connected to the indoor circulation port 12. In the internal circulation state, opening the indoor circulation port 12 and the circulation fan 43 can realize the air circulation indoors, and filter out impurities in the gas and adjust the gas temperature during the circulation.

[0026] As Figure 1 shown, two total heat cores are longitudinally connected in series in the box body 1, namely the total heat core I 6 and the total heat core II 61. By connecting the two total heat cores in series and cooperating with a plurality of partitions 18, the interior of the box body 1 is divided into an indoor return air chamber 5, a fresh air supply chamber 4, an outdoor exhaust air chamber 7, and an outdoor intake air chamber 8.

[0027] The indoor return air chamber 5 is respectively connected in parallel with the total heat core I 6 and the total heat core II 61 and then connected to the outdoor exhaust air chamber 7. The outdoor intake air chamber 8 is connected in series with the total heat core II 61 and the total heat core I 6 and then connected to the fresh air supply chamber 4.

[0028] A fresh air fan 41 is arranged in the fresh air supply chamber 4. The fresh air fan 41 blows the air flow into the filter chamber 31, and the terminal filter 3 is fixed in the filter chamber 31.

[0029] Further, an indoor gas filtration module 44 is arranged in the box body 1 corresponding to the indoor circulation port 12 and the indoor return air port 13. The indoor recycled gas is uniformly filtered through the indoor gas filtration module 44. During actual operation, to prevent the air flow from flowing around inside the indoor gas filtration module 44, the present utility model is provided with a spacing device on the indoor gas filtration module 44. The indoor gas filtration module 44 is divided into two parts by the spacing device and is respectively independently arranged corresponding to the indoor circulation port 12 and the indoor return air port 13.

[0030] Furthermore, an outdoor gas filtration module 81 is arranged in the box body 1 corresponding to the outdoor intake air port 15. The outdoor fresh air is preliminarily filtered through the outdoor gas filtration module 81.

[0031] The utility model is provided with a top cover 10 and a bottom cover on a box body 1. A plurality of maintenance openings are arranged on the top cover 10, namely an end filter maintenance opening 32, an indoor filter maintenance opening 45, and an outdoor filter maintenance opening 82. The above-mentioned maintenance openings are of an openable type and are respectively arranged corresponding to an end filter 3, an indoor gas filtration module 44, and an outdoor gas filtration module 81. External personnel can replace and maintain the internal filtration modules through the respective maintenance openings.

[0032] When the utility model is in use, as Figure 5 shown, fresh air enters from an outdoor air inlet 15 and is primarily filtered by an outdoor gas filtration module 81, then sequentially passes through a total heat core body II 61 and a total heat core body I 6 for series heat exchange, enters a fresh air supply chamber 4, is pressurized by a fresh air fan 41, is secondarily filtered by an end filter 3, is temperature-adjusted by an evaporator 2, and then enters the room through an indoor air supply opening 17.

[0033] The air in the room enters an indoor gas filtration module 44 through an indoor air return opening 13 for filtration, and simultaneously passes through the total heat core body II 61 and the total heat core body I 6. At this time, the indoor gas is heat-exchanged with the outdoor fresh air, then enters an outdoor exhaust chamber 7, is pressurized by an outdoor exhaust fan 71, and is discharged to the outside through an outdoor exhaust opening 16. Through the above structural arrangement, this solution uses two total heat core bodies to make up for the size defect of a single core body, and adopts a longitudinal double-section layout to reduce the waste of longitudinal space. At the same time, fresh air is in contact with double-section return air for recovery, improving the secondary recovery efficiency, with a higher recovery efficiency and reducing the indoor load.

[0034] Embodiment 2:

[0035] On the basis of the structure of Embodiment 1, since such a dual total heat environmental control integrated machine is fixed at the roof and is suspended, during operation, it is only supported by four suspension bars. Because the multiple fans in the box body 1 will vibrate during operation, to prevent such vibration from being transmitted to the outside and thus generating resonance or an increase in noise, the utility model improves the suspension bar pulling structure as follows: A suspension bar seat 11 is arranged on the side wall of the box body 1. As Figure 4 shown, the suspension bar seat 11 includes a mounting plate 111 and a hoisting plate 112. The mounting plate 111 and the hoisting plate 112 are arranged in a right-angle bending manner, and end baffles 114 are respectively arranged at their end parts. A vertical edge 115 is arranged at the outer end of the hoisting plate 112, and the outer side is blocked through the vertical edge 115. A hoisting groove 113 is arranged in the middle of the hoisting plate 112.

[0036] When the hanger seat 11 is hoisted and fixed, elastic blocks are arranged at both the upper and lower parts of the hoisting plate 112, and a tension bar penetrates through the elastic blocks. The end baffle 114 and the vertical side 115 enclose a vertical blocking area, and the horizontal constraint of the elastic block located at the upper part is realized through the vertical blocking area to prevent the elastic block from moving horizontally. During the operation of the equipment, the vibration of the equipment will be absorbed by the elastic blocks to avoid the external transmission of noise and vibration.
