It should be noted that, the heat recovery runner apparatus 8 is a runner heat recovery apparatus comprising a heat recovery runner, a fresh air duct, an exhaust air duct, and the like, and the specific structure thereof is the prior art and will not be described herein.
In this embodiment, the air conditioning unit 4 is a combined air conditioning unit 4, which sequentially includes a primary filter 41, a surface cooler 42, a dehumidifier 43, a main blower 44, a heater 45 and a humidifier 46 along the fresh air conveying direction, and can cool and dehumidify fresh air in summer and warm and humidify in winter.

The variable frequency fan 5 replaces the traditional VAV BOX air valve to serve as an air volume adjusting mechanism, and the air delivery pipe of each cabin 200 is provided with the variable frequency fan 5 serving as a tail end air volume adjusting device and adopts a PID control mode.
In addition, a temperature monitoring device 210 is further disposed in each cabin 200 to monitor the temperature in the cabin 200 and transmit a temperature feedback signal, and the temperature feedback signal is compared with the set temperature of the indoor personnel to adjust the frequency of the frequency converter and the rotation speed of the fan. Meanwhile, the air quantity control network of the total air feeder 44 of the VAV system is also provided, the rotating speed signals of the variable frequency fans 5 of each cabin 200 are transmitted to the control box 7 through the DDC, so that the rotating speed of the total air feeder 44 is controlled, and the total air quantity of the total air feeder 44 is slightly larger than the sum of the actual air quantity of each tail end in order to ensure that a certain positive pressure is arranged in a pipeline. Compared with the traditional VAV BOX air valve serving as an air quantity adjusting mechanism, the system resistance characteristic caused by frequent adjustment of the opening degree of the air valve can be prevented from generating larger change, so that the total air quantity of the air treatment unit can be adjusted stably and effectively, and meanwhile, the air supply pressure at the tail end of the system is ensured.
In addition, it should be understood that one end of the fresh air main pipe 1 is connected to the first fresh air branch pipe 11 and the second fresh air branch pipe 12 at the same time, and the other end is used for being placed outside, so that fresh air can be introduced. And one end of the main return air pipe 3 is connected to the first return air branch pipe 31 and the second return air branch pipe 32 at the same time, and the other end is used for communicating with the cabin 200 to facilitate return air.

In this embodiment, when the air conditioner is operated under the epidemic situation, the control valve on the third return air branch pipe 33 may be opened, so that part of the return air can directly enter the air conditioner box 4, thereby further reducing energy consumption and improving energy utilization rate. And when the air conditioner operates under epidemic conditions, the control valve on the third air return branch pipe 33 is closed, so that the air return can be only conveyed to the second air channel 21b by the second air return branch pipe 32, and cross infection of fresh air and air return is avoided.
For convenience of understanding, the control valves on the first fresh air branch pipe 11, the second fresh air branch pipe 12, the first return air branch pipe 31, the second return air branch pipe 32 and the third return air branch pipe 33 are defined as follows: the first control valve 111, the second control valve 121, the third control valve 311, the fourth control valve 321, and the fifth control valve 331.

Thus, when the air conditioner operates under the epidemic-free condition, the control valve on the air supply pipe 6 is closed, so that the reverse conveying of the fresh air through the heat exchange of the fresh air duct of the heat recovery runner equipment 8 to the first air duct 21a is avoided, and the energy loss is avoided. And when the air conditioner runs under epidemic situation, a control valve on the air supply pipe 6 is opened, so that fresh air exchanged by the heat exchanger 2 can be smoothly conveyed from the first air duct 21a to the air conditioner box 4 by the air supply pipe 6. Specifically, the control valve on the air supply duct 6 is defined as a sixth control valve.
In this embodiment, each control valve is in the form of a solenoid valve. And the air conditioning system 100 further includes a control box 7, and the control box 7 is electrically connected with each control valve to control the opening degree of the valve through a programmable logic controller in the control box 7. When the opening of the fifth control valve 331 is reduced to reduce the amount of return air directly entering the air conditioning case 4 during operation under epidemic situation, the second control valve 121 is adjusted to be opened to increase the amount of supply air, and the ratio of fresh air to return air is adjusted. And when the epidemic situation is serious, the third control valve 311 and the fifth control valve 331 are closed, so that the fresh air running is realized to ensure the air supply safety.

And when in summer, fresh air is cooled, exhausted air is heated, the part of the heat pipe 23 positioned in the first air channel 21a is an evaporation section, and the part of the heat pipe positioned in the second air channel 21b is a condensation section. It should be understood that in summer and winter, the evaporation section is located below the condensation section to circulate heat exchange by means of ammonia dead weight, saving cost and having excellent heat transfer performance. Specifically, the rotation part 221 is driven to rotate, so that the vertical up and down positions of the evaporation section and the condensation section are adjusted in summer and winter.
