Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a cockpit air purification system. Background Art

[0002] The HVAC system can operate in an external circulation mode or an air recirculation (i.e., internal circulation) mode. The power consumed by the HVAC system of an electric vehicle is mostly between 1 - 2 kW. That is, for every hour the air conditioner is turned on, the cruising range is reduced by about 10.9 kilometers. If the vehicle is in the external circulation mode but at the maximum air volume condition, the cruising range is reduced by an additional 7 km per hour. That is, if the HVAC system is in the external circulation mode, the vehicle is in the external circulation mode, and the HVAC system will reduce the cruising range by 17.9 kilometers per hour. This will greatly reduce the cruising range of the electric vehicle.

[0003] If the HVAC system is in the air recirculation mode, the power consumption will be greatly reduced. However, an adult usually exhales about 30 grams of water per hour and about 40 grams of carbon dioxide per hour. If the HVAC system is always in the air recirculation mode during vehicle driving, the water vapor emitted by the human body will cause the vehicle glass to fog up, bringing unpredictable dangers to the vehicle drivers and passengers. If the defogging mode is continuously turned on, it will increase the power consumption and reduce the cruising range of the vehicle. Moreover, in the air recirculation mode, the CO 2 in the vehicle will continuously increase, causing the driver to feel sleepy during driving, bringing potential dangers to the normal operation of the vehicle. Therefore, it is necessary to develop a carriage air recirculation system so that the vehicle can filter and adsorb harmful substances such as water vapor and carbon dioxide in the carriage air, thereby avoiding fogging during vehicle driving and ensuring that the driver and passengers will not be fatigued and sleepy due to excessive carbon dioxide concentration.

[0004] However, the current cockpit air purification systems often need to replace the adsorption unit frequently and cannot achieve the normal operation of the air purification system when replacing the adsorption unit.

[0082] The cockpit air purification system of this embodiment purifies the air inside the vehicle. When the vehicle is in the internal circulation mode, it filters and purifies the water vapor and carbon dioxide in the vehicle interior air, preventing the vehicle from fogging up during driving, ensuring that the driver and passengers are not fatigued or sleepy due to excessive carbon dioxide concentration, reducing the number of times the vehicle switches to the external circulation, thereby reducing the energy consumption of the air conditioning system and greatly increasing the vehicle's cruising range.

[0083] The cockpit air purification system of this embodiment has the following two working modes specifically:

[0084] 1. Pure adsorption working mode: The first driving component 32 on the air inlet 11 drives the air inlet sealing component 33 of the air inlet flap unit 3 to block the lower gas diversion channel 12, and at the same time, the second driving component 52 on the air outlet 41 drives the air outlet sealing component 53 of the air outlet flap unit 5 to block the lower gas discharge channel 42. At this time, air flows through the upper adsorption unit 2 through the air inlet 11 for adsorption and filtration, and is then transported to the air inlet of the air conditioner's internal circulation through the air outlet 41. Conversely, if the upper gas diversion channel 12 and the gas discharge channel 42 are blocked, air can flow through the lower adsorption unit 2 through the air inlet 11 for adsorption and filtration, and is then transported to the air inlet of the air conditioner's internal circulation through the air outlet 41. Thus, single-channel gas purification and adsorption can be achieved.

[0085] 2. One-side adsorption while the other side is regenerated mode: By monitoring the gas humidity inside the air outlet 41, after determining that the adsorption resin in the upper adsorption box 21 is saturated, the first driving component 32 on the air inlet 11 drives the air inlet sealing component 33 of the air inlet flap unit 3 to the middle position of the air inlet 11. At the same time, the second driving component 52 on the air outlet 41 drives the air outlet sealing component 53 of the air outlet flap unit 5 to block the upper gas discharge channel 42. At this time, the upper heating unit 6 starts to work. Air passes through the air inlet 11, a small part of the gas flows through the upper heating unit 6 to heat the air, and then flows through the adsorption unit 2 to heat and desorb the adsorption material in the adsorption box 21 for regeneration. The highly humid gas generated during regeneration is discharged from the exhaust port 45 out of the air purification system. At the same time, most of the air introduced from the air inlet 11 flows through the lower adsorption unit 2 for adsorption and filtration, and is then transported to the air inlet of the air conditioner's internal circulation through the air outlet 41. By monitoring the humidity value of the air inside the exhaust port 45, after ensuring that the resin regeneration in the adsorption box 21 is completed, the air inlet sealing component 33 is driven by the first driving component 32 on the air inlet 11 to block the upper or lower gas diversion channel 12, entering the pure adsorption working mode. By monitoring the gas humidity inside the air outlet 41 and performing the above operations cyclically, continuous adsorption work of the air purification system of this embodiment can be achieved.
