The invention provides a vehicle air conditioning box, a vehicle air conditioning system and a control method thereof.The vehicle air conditioning box comprises a box body shell, the box body shell is provided with an inner space, a main heat exchange air duct is formed in the inner space, and an air inlet and an air supply outlet are formed in the box body shell; an in-vehicle heat exchanger and an in-vehicle fan corresponding to the in-vehicle heat exchanger are arranged in the main heat exchange air duct, an inlet of the air return duct is controllably communicated with an air outlet side space of the in-vehicle heat exchanger, and an outlet of the air return duct is communicated with an air inlet side space of the in-vehicle heat exchanger. The air inlet side space and the air outlet side space are both located in the main heat exchange air duct. The air return duct is arranged on the air conditioning box, so that part of airflow subjected to heat exchange with the in-vehicle heat exchanger can be guided into the air inlet side space of the in-vehicle heat exchanger to enter the in-vehicle heat exchanger again for secondary heat exchange, and it is guaranteed that the air outlet temperature of the air conditioning system can reach the temperature value set by a user; and the use comfort and the satisfaction degree of the user are improved.

    本发明提供一种车用空调箱、车辆空调系统及其控制方法,其中车用空调箱,包括箱体外壳,箱体外壳具有内部空间,内部空间中形成有主换热风道,箱体外壳上构造有进风口及送风口,主换热风道内设置有车内换热器及与之对应配置的车内风机,车用空调箱还包括回风风道,回风风道的入口与车内换热器的出风侧空间可控连通,回风风道的出口与车内换热器的进风侧空间连通,且进风侧空间及出风侧空间皆处于主换热风道内。本发明通过在空调箱上设置回风风道能够将与车内换热器进行热交换之后的气流中的一部分引流至车内换热器的进风侧空间内再次进入车内换热器进行二次换热,保证空调系统的出风温度能够达到用户设定温度值,提升用户的使用舒适性以及满意度。
