Description

Technical Field

[0001] The present invention relates to heating, ventilation and air conditioning (HVAC) systems for vehicles, and more particularly to cabin air control systems for HVAC systems. Background Art

[0002] The HVAC system can be operated in an external circulation mode or in an air recirculation (i.e., internal circulation) mode. The power consumed by the HVAC system of an electric vehicle is mostly between 1-2kW, i.e., the air conditioning will reduce the mileage by about 10.9 kilometers per hour. If the vehicle turns on the external circulation, but under the condition of maximum air volume, the mileage will be reduced by an additional 7 kilometers per hour, i.e., if the HVAC system turns on the external circulation mode and the vehicle is in the external circulation mode, the HVAC system will reduce the mileage by 17.9 kilometers per hour. This will greatly reduce the mileage of the electric vehicle.

[0003] If the HVAC system is in air recirculation mode, the power consumed will be greatly reduced. However, an adult usually emits about 30g / hour of water and about 40g / hour of carbon dioxide through breathing. If the HVAC system is always in air recirculation mode when the vehicle is moving, the water vapor emitted by the human body will cause fogging on the vehicle glass, which will bring unpredictable dangers to the vehicle driver and passengers. If the defog mode is turned on continuously, this will increase power consumption and reduce the mileage of the vehicle. In addition, in air recirculation mode, the CO2 in the vehicle will continue to increase, which will cause the driver to get drowsy during driving, which will bring potential dangers to the normal operation of the vehicle.

[0004] At present, a dual adsorption unit structure including a first adsorption unit and a second adsorption unit has been proposed. However, the dual adsorption unit structure has a large volume, which increases the difficulty of vehicle layout; it is heavy, and the dual adsorption unit structure itself needs to add more components to strengthen the structure; in addition, the cost is high, and the dual adsorption unit needs to manage two heaters and two motors separately.

[0005] To this end, it is necessary to develop a single adsorption unit structure that ensures performance, has a relatively small size, has a relatively light weight, uses a single heater and a single motor to achieve operational control, which reduces manufacturing costs, greatly improves the compatibility of vehicle air control systems, and at the same time meets the basic functions of vehicle energy saving, thereby improving the market competitiveness of the system. Summary of the invention

In the first outlet position, the blocking pad 106 blocks the exhaust duct 14; in the second outlet position, the blocking pad 106 does not block the exhaust duct 14.

[0071] When the cabin air control system is in adsorption mode ( Figure 7 ), air with high humidity and / or high concentration of CO2 enters the air inlet passage 12 through an air conditioning fan (not shown), and then the air is delivered to the adsorption unit 3 via the adsorption chamber 16. The air is dehumidified and / or purified, and then the air flows through the outlet opening 13 and returns to the air conditioning system and is distributed to various areas in the cabin as needed.

[0072] When the cabin air control system is in regeneration mode ( Figure 8), air is delivered to the air inlet passage 12 by the air conditioning fan, and then the air is delivered to the heater 4 via the regeneration air chamber 15. The heater 4 is in operation, the air is heated to a set temperature, and then the heated air is delivered to the adsorption unit 3, and the adsorption material in the adsorption unit 3 is regenerated. The exhaust gas containing gas such as CO2 and water after regeneration flows to the environment through the exhaust pipe 14.
