Of course, the air conditioning unit 1 may also use all the fresh air from the outside as the intake air. If in special cases, such as the case that the sterilization and disinfection are required to be carried out regularly, or during the epidemic situation, each sterilization and disinfection unit can be started to realize the sterilization and disinfection treatment of the air.
When the air conditioner is used, fresh air output from an air supply outlet of the air conditioning unit 1 enters the static pressure box 2 through the main air supply pipe 100, then enters each pressure equalizing pipe 3 from the static pressure box 2, air in each pressure equalizing pipe 3 is sent into each air supply unit 5 through the air guide pipe 4, an air outlet 511 on each air supply unit 5 outputs the fresh air, and then the fresh air processed by the air conditioning unit 1 through functions of filtering, humidifying, temperature adjusting and the like is provided around a seat. When the sterilization and disinfection treatment is needed, the first air filtering and disinfecting unit 101 on the main air supply pipe 100 is controlled to be opened, and a corresponding air treatment device is additionally connected to the reserved air opening 102 for further air treatment.
And the air in the public space enters the second air return pipe 200 from the air return opening of the public space, and the fan 201 and the valve on the air exhaust pipe 200 are opened, so that the air is exhausted out of the public space from the air exhaust pipe 200.
The use of the disinfection area 6 can be further started during an epidemic situation, a part of fresh air in the main air supply pipe 100 is shunted to the disinfection air supply pipe 61, and the second air filtering and disinfecting unit 611 on the disinfection air supply pipe 61 is also started to disinfect the personnel entering the disinfection area 6. The return air in the disinfection area 6 enters the disinfection return air pipe from the return air inlet of the disinfection area 6, and the third air filtering and disinfecting unit 621 on the disinfection return air pipe is started to work so as to disinfect the air in the disinfection return air pipe. The air in the disinfection return air pipe can be discharged from the air exhaust pipe 200 or sent into the air conditioning unit 1 as required, and before being sent into the air conditioning unit 1, the fourth air filtering and disinfecting unit 111 on the first return air pipe 11 is also opened, so that the return air entering the air conditioning unit 1 is further disinfected.
The three-wind equivalent balance ventilation air-conditioning epidemic prevention system in the public space forms a radial air supply system which takes the static pressure box 2 as the center, the pressure equalizing pipe 3 as the radiation range and the air guide pipe 4 as a multi-pole air supply point, the paths from the static pressure box 2 to the air supply tail end are basically consistent, so that the equivalent balance of the air quantity, the air speed and the air pressure reaching each air supply unit 5 can be realized, namely, the air sent to each tail end in the public space achieves the equivalent balance effect, and the problem of unbalanced air quantity, air speed and air pressure sent in the public space in the prior art is solved. Meanwhile, in the air supply process, the static pressure box 2 is not directly communicated with the air outlet 511, so that the static pressure box 2 with a small volume is not needed, and the air reaches the air supply tail end through a pipeline, so that the requirements of low air speed and low air volume of tail-end air outlet are met. Meanwhile, the requirements of the air supply end on high air speed, high air volume and high air pressure are reduced, energy is saved, the time that fresh air reaches the air outlet 511 is shortened, and the clean fresh air can be rapidly output and used.
On this basis, still set up filtration disinfection unit, can filter and disinfect the disinfection to the air, can satisfy the high requirement to the air quality during the epidemic situation very much, satisfy the normal use in high density crowd's public space.
